Hmph. (Jumpy) Touchpad issues and Suspend idiosyncrasies.

(I'll try not to turn this into a novel, but I guess when I have a problem it just happens that I naturally try to describe everything that goes on for full disclosure. Bear with me.)
I just got a hold of an older laptop, a Dell Latitude C640, and to my dismay setting up Linux on it hasn't been the walk in the park I'd hoped it'd be. I read a bunch of articles about Linux on this machine before I got it and most seemed to have a pretty easy time of everything. Of course this might be because the laptop is quite a few years old and older Linux kernels acted different ways, but I guess I assumed that things would be even easier using a modern distro.
The Touchpad
It worked fine on the install of Windows XP that came installed on it, with no problems at all. Before installing any flavor of Linux I ran Knoppix on it just kind of to make sure things would go OK. It was a little dated, being Knoppix 5.10, but I figured it'd do for my purposes.
The first time I booted it seemed to work OK, with the mouse cursor behaving mostly as it should, with a little lag. I've used this same Knoppix disk on another laptop and it did much the same thing. After another boot, however, I saw that things weren't going to be so easy. The cursor immediately drifted off into one of the screen's corners (it didn't seem to care much which one it was in, as long as it was in one) and would refuse to come out. I could move the cursor a little ways off of the edge of the screen, but not far enough to click anything, and it would immediately go back as soon as I released my finger. So I tried a few other disks. First I tried a CD I have for Crunchbang Linux (just a minimalist, Openbox-based Ubuntu flavor), and then Knoppix 4. Both gave very similar results. Crunchbang let me have a little bit more control over the cursor for a little while after booting, maybe for about a minute, and then the same behavior cropped up. I only booted with Knoppix 4 once, but it was pretty much the same deal.
I started reading up on what might be going on and came across a thread on the Linux Mint forums that seemed to be describing an issue very close to mine (though mine is completely unrelated to the AC adapter and persists whether it's plugged in or not). Someone in the thread suggested it was a kernel issue, since it's definitely not a hardware issue, so I then booted into a copy of DSL I had lying around, which uses the 2.4 kernel. Sure enough everything worked without problems. This caused me to believe, going by some of the conclusions from the Lnux Mint thread and apparently mistakenly, that the issue may have been with the 2.6 Debian kernels, so I figured I'd just get Arch installed and see how things went.
After getting X set up and working properly I saw that the issue was going to be much the same. To get around the cursor being dragged into the corner against my will I found out that if I ran without HAL or that if I disabled hot-plugging I could use the touchpad, although not flawlessly. Here's xorg.conf:

The "AutoAddDevice" option is the only thing that seems to make any difference in usability at all; without it I can't use the touchpad at all, and with it I can, but to varying degrees. I've found that right after I boot up everything seems to work exactly how it's supposed to, but shortly after, sometimes 15 seconds, sometimes many minutes, things seem to get kind of unresponsive. The cursor will go where I want it to go, but it jumps around and does it very slowly. The mouse buttons also get very unresponsive. Right click is especially bad, and I often have to hold down the button just to get it to do what I want, but left click is very bad too, requiring me to push the button down for almost a full second, sometimes several times. Taps on the pad, after things go wrong, also stop being recognized, forcing me to use the buttons (which I'm OK with). It's usable, but the behavior is not ideal whatsoever—it's rather annoying.
The most aggravating thing, I think, is that I can't seem to find anyone else using this same model that has this issue. The latest I've seen is from January: An Ubuntu (8.10) user reports no issues and is very pleased (see comments at the bottom of the page).
Suspend (both to disk and RAM)
I actually did install the latest Crunchbang (9.04.01, the 32-bit "Lite" edition) first to see if anything would clear up by installing it rather than running the live CD, but I only had it installed for a few hours. I didn't really get into messing with xorg.conf that much yet, only really touching "FingerLow" and "FingerHigh" settings, so the touchpad issue was still nagging me. I did play around a bit though and found out that suspend to RAM and suspend to disk worked pretty much from the go, only requiring that I installed uswsusp. Issuing a simple "sudo pm-suspend" or "sudo pm-hiberate" put the computer to sleep and it woke back up without any issue at all.
But suspend on Arch is proving to be a pain in the neck. Suspend to RAM simply will not work; the computer shuts down but will not resume, leaving me only a blank screen with an unresponsive keyboard. Suspend to disk works (using hibernate-script as pm-hibernate doesn't seem to do anything at all), but it works very poorly; both suspending and resuming take a very, very long time—so long, in fact, that I'm just better off shutting down and restarting normally, since the boot time is better. I don't know what accounts for the drastic difference in distros, and this isn't the first experience I've had with suspension working on Ubuntu but not on Arch. What is different in the Ubuntu implementation of pm-utils than the Arch way? Is it the Ubuntu kernel? Is there any way to implement the Ubuntu way with Arch (because, after all, I'd prefer to use Arch)?
I'm considering installing Crunchbang once again if I can't get things to work the way I want them to in the next few days on Arch. And, if I can't make the touchpad work in a satisfactory manner on Cruchbang, I might just have to reinstall Windows. I don't want to do that.

At least for the moment I've given up and reinstalled Windows XP, but I'm still kind of looking for solutions. Suspend and hibernate are things I find to be somewhat important, but secondary to the touchpad issues, so I'm focusing on those.
Out of curiosity today I test out pretty much every live CD I have in the house. I found an old Ubuntu CD for 6.06 (Dapper) and had a little bit of luck with it. By default pretty much every live CD configures Xorg to use an additional mouse that isn't present; to fix this I edited the "ServerLayout" section xorg.conf to only use the touchpad. With this old Ubuntu CD, this achieved the desired result (mostly). The touchpad worked how it ought to with no lag, but a few features were not implemented.
Ubuntu 6.06 used the 0.4.3 version of the synaptics driver; newer Linux distros usually use 0.99 and above. I tried my Knoppix 5.1 CD again, editing xorg.conf again to reflect the absence of an external mouse, but I did not get the behavior I was hoping for. When I checked I found out that Knoppix 5.1 came with the 0.14.6 version of the synaptics driver.
Turns out that 0.14.5 was something of a turning point for the driver.
Makefile support for Xorg 7.0 has been added.
Two-finger scrolling and pressure dependent motion
speed have been implemented. A new parameter has
been added to give greater control over tap
behavior.
(http://freshmeat.net/projects/synaptics/releases/228794)
I suspect that the problem is coming from the addition of the "pressure dependent motion speed." I don't know what options control this to toy with them.
However, I'm not so sure. This sounds like it would be something that would toy with my mind, making me think I'm experiencing "mouse lag" when certain options are really just conflicting, but as I had to point out again on another forum on which I posted this same thread, when using Arch (and the most recent synaptics driver) things started out fine and only after a little while, sometimes less than a minute, sometimes many, would things start to act up. Either some progress is being made to resolve this problem with the latest releases, or something is going wrong internally that I do not understand. I just cannot understand why, with the newest drivers, it's only after some use that the problem kicks in while when using all others the problems are immediate.

Windows 8 and touchpad issues

I upgraded an old Toshiba L45-S7423 laptop from Windows XP to Windows 8 Pro recently via CD/DVD. A couple of days later, the touchpad stopped working, but a USB mouse works just fine. The touchpad issue might be related to a Windows update that occurred
about the same time. The laptop has been running Windows XP for several years without issues other than slow boot and shutdown. Of course, I know very little about Windows 8. Any ideas on how to proceed. Thanks!

Hi,
It seems the issue is more related to the driver update from Microsoft site. I recommend performing System Restore first. Then, you may prevent installing the hardware driver updates from Microsoft right now.

Touchpad problems ((and other Windows 10 issues)

I upgraded to Windows 10 pretty smoothly, but I'm experieiincing the same problems as others when it comes to using tablet mode etc. My biggest frustration though is that the touchpad no longer consistently supports two-finger scrolling, which is sooo frustrating. Also, edge-swipe gestures to bring up things like the app-switcher and charms bar (is it still called that?) don't work either. I've updated to the latest drivers (all of the ones that Lenovo has at ths point) and that doesn't seem to fix any problems. Anyone know how to solve the touchpad issues? Also, seriously disapponted with the Lenovo support on these issues. The Yoga went from being one of my favorite laptops to being one of my least favorite with this OS "upgrade" and next time, I'll probably get a computer from Dell.

Hi, I too was experiencing simlar frustrations on my Flex 2-15" which uses a similar touchpad, the movement would even stop all together for about 15-20 secs, extremely frustrating!! Since my wireless mouse would work just fine I knew it had to be an issue with the drivers. So the updated driver version for win 10 min my case is going from v17(win8) to v19+(win10). I noticed that the Device Manager driver was showing that new version but the Synaptics control panel was reading that the driver was still 17 which I could see might cause issues for the hardware input to be read properly. Here is how I fixed it: 1) If you haven't already, download the windows 10 driver for your specific computer/ trackpad from this site. 2) Go to your device manager cpl and expand the pointer mouse objects and uninstall all of the drivers but DO NOT reboot immediately. 3) Goto the Programs and Features cpl and uninstall the Synaptics program (or ELAN / Alps depending on your stock controller app) 4) Reboot when prompted. 5) Run the download in step one and install the driver and Synaptics app when prompted NOTE: In my case the Synaptics install would not open on its own and had to open it's setup.exe manually <<C: drivers\Touchpad Driver(Elan, Synaptics, ALPS)\2al301af\Synaptics>> If you still have the issue, try running through the steps while disconnected from the internet. It might be auto-updating with the wrong data. I hope this helps those afflicted my this annyoing issue.~gC

U310 jumpy touchpad with pluggen ac\dc adapter

u310 jumpy touchpad with pluggen ac\dc adapter - impossible to work with notebook
I have this very strange problem. Ever since getting a replacement AC adapter for my laptop, the mouse has started going all crazy. If the adapter is unplugged, the mouse works perfectly fine, but the second I plug the adapter back in it goes crazy again. I've heard of this problem before but I'm unaware of any solutions. Any help would be much appreciated.
can you give me a firmware for my touchpad? or should vendor to replace ac adapter?

HP Envy 15 Heating Issues and Screen Damage

Hello,
This is going to be quite long since I'm going to explain everything in as much detail as possible.
I bought my HP Envy 15 (j123tx) in September 2014 and for three months I had absolutely no issue with it (work wise and gaming wise) until one day I booted up the computer and noticed that a big rectangular portion of the screen (on the top - in the rectangular area that aligns with the touchpad when the lid is closed) was discoloured. Specifically it was much darker than the rest of the screen on a black background and yellow on a white background.
After checking to see if there was anything on the screen's surface, I realized it was a hardware issue and decided to use my warranty (of which I have another 8 months or so remaining). I told the retailers about the issue and they told me it could be because of the pressure applied on the lid (when it is closed) that affects the screen specifically in that area since the touchpad is a bit sunken in to the notebook's body. After expressing my displeasure at how inconvenient that is since I've taken very good care of my notebook and have only transported it in the HP notebook bag, they promised me that they would send it to the HP Service Center in Sri Lanka who would replace the display panel for me (obviously since my notebook is still under warranty).
After 10 working days, I went over to the retailer's warranty center and collected my notebook with the display panel replaced and the problem gone. I did however notice that the technicians had pasted a note next to the touchpad which read "Check the temperature of the touchpad. It could be heating up and damaging the screen". I asked the retailer's technicians what this meant and they told me that since the notebook has a magnesium (or magnesium based) body, it tends to heat up. The heat could also be heating up the touchpad (since that too seems to be made of magnesium). As a result whenever I close the lid of my notebook, the rectangular screen area directly above the touchpad could be heating up and thus getting damaged.
Now this to me seems like a huge product defect. I've been using HP notebooks for more than 8 years and I've never heard of this issue before. I asked the technicians how I could prevent this from occurring again and they told me to use the little cloth that came with the laptop when I bought it that is placed under the lid (between the screen and the keyboard) when the lid is closed.
While using that little cloth doesn't seem to be quite inconvenient, I'm very afraid that the problem will occur again and I'll have to get it fixed again which involves transferring all my data and losing my notebook for 2 weeks which is highly problematic for me as I require it for work. Should the problem occur again outside the warranty period, I feel I may have wasted a good amount of money on this notebook when I trusted HP over its competitors simply due to my past experiences with its reliability, durability and performance.
While I realize this is not a current issue - I would really like to know if this issue has been experienced before (my search did not turn up anything related) and if I do have to be worried about it happening again and if so, how I should go about handling it with the retailers (perhaps I should give it back and ask for a refund for selling me a defective product).
Thank you sincerely.
PS: I have attached a picture of the problem when it occurred for your reference.

Thanks for the prompt reply WeiH.
Sadly there doesn't seem to be an HP Service Center in my country (Sri Lanka). So now I'm really confused as to what my retailer's technicians meant by "we'll send it to the local HP Support Center and have your display panel replaced".
Whatever they did, the display panel has been replaced and I've been using it for less than a week so far with no issues. The touchpad hasn't really been heating up and has in fact been as warm as the rest of the notebook. Perhaps it's because I have now turned on the option of disabling the touchpad whenever an external cursor device is attached (since I primarily always use a mouse).
Needless to say, since we both have no clue as to how the touchpad overheated and damaged the screen (in the exact position and measurement as the touchpad) I feel like it's just a matter of time before it happens again.
Obviously I understand that there's little you can do on your side other than direct me to an HP Support Center. However I hope my worries are justified as I feel that as a consumer I shouldn't have to worry about my brand new product malfunctioning by no fault of my own.

HP Touchpad Issues - HP ENVY 15t-q100 - Needs Reflashed to Function Properly -

I have the HP Slim Quad 100 Notebook with the HP Synaptics Touchpad.
The touchpad intermittently stops working correctly. Sometimes it's so bad that it's unusable.
I have done a little research and I found that the driver is causing the Touchpad to detect clicks and touch when there is none. I've confirmed this by looking at the real-time Pressure graph tool that measures Touch Pressure.
According to the Synaptics Pressure Graph tool (in the Synaptics folder, the red "Z" Icon [SynZMetr] is the name), the Touchpad is detecting pressure even when my hand is off the Touchpad altogether. I suggest that anyone with this same issue confirm this themselves as well, during your time of random malfunction and sporadic movements. You will see pressure in the pressure graph even when there is no contact with the touchpad.
My temporary solution:
Double click on the 'Reflash' folder in the Synaptics folder:
C:\Program Files\Synaptics\SynTP\SynReflash
After I reflash using this method, the issue is fixed immediately. However, sometimes I have to do this on a daily basis!!! What is the root issue and how can I fix it???
Other Troubleshooting:
I've reinstalled the newest driver a few times:
Current Version:
Synaptics Touchpad Driver -18.1.7.8 , Size: 187.8 MB -- Oct 11, 2014
File name: sp66500.exe
^ This did nothing to solve the problem from re-occurring.

Compilation of Lenovo X120e issues and solutions

Just thought a compilation of issues may be beneficial for folks who own an X120e.
Screen adjusts brightness automatically without user input depending on content on screen:
http://forum.lenovo.com/t5/X-Series-ThinkPad-Laptops/X100e-screen-brightness-increasing-by-itself/td...
This is caused by Vari-Bright being enabled in the Catalyst Control Center. With this option enabled, the screen will automatically adjust its brightness depending on what is shown on the screen. The display brightness is increased when the screen is predominantly white while the display brightness is decreased when the screen is predominantly dark. An easiest way to see this effect happening is to have two tabs opened in a web browser window. Set one tab to display a website that is mainly filled with white pixels (such as this Lenovo Forum) and another tab to display a website that is mainly filled with dark pixels (such as http://www.krijtenberg.nl/ ). Switch between the two, pausing a few seconds in each tab.
Solution:
Open the Catalyst Control Center and select the PowerPlay option in the Power section. Uncheck the Vari-Bright option (or adjust the slider) and click Apply. Verify that the automatic adjustment is no longer occuring by doing the two tab experiment described above.
Function keys for brightness control not working after waking from sleep / hibernation in some instances:
http://forum.lenovo.com/t5/X-Series-ThinkPad-Laptops/x120e-Funtion-keys-for-brightness-not-working/t...
For my X120e, whenever I have it sleeping or hibernating and change the power source (such as initiating sleep when on power and then waking it up while on battery, or vice versa), the function keys for brightness controls do not work.
Solution:
Restarting the machine will bring back functionality of the brightness control keys...
A way to prevent this from happening in the first place is to wake the X120e in the same power state that the X120e was put to sleep in (wake up from power adapter if slept while connected to power adapter, or wake up from battery if slept while on battery).
All we can do now is wait for Lenovo to come up with a fix on their side of things.
AMD SATA Controller and TRIM for SSD:
The AMD SATA Controller provided by Lenovo does not support passing of TRIM command according to http://www.hardwarecanucks.com/forum/450343-post35.html for SSDs. The Lenovo provided AMD SATA Controller is 1.2.1.197, before the official TRIM support in 1.2.1.263. If you're using a HDD, this is of no concern.
Solution:
In order to have support for passing of TRIM command, one has to update the AMD SATA Controller to any version above 1.2.1.263 ( http://sites.amd.com/us/game/downloads/Pages/integrated_win7-64.aspx#3 for Windows 7 64-bit, for example) or uninstall the AMD SATA Controller to revert back to Microsoft's Standard AHCI 1.0 Serial ATA Controller.
Disclaimer: Since the AMD SATA Controller driver linked is not from Lenovo themselves, I'm sure they won't provide any support if something is to occur so try at your own risk.
As HP79 mentions below, at least according to the update notes, TRIM implementation is implemented for Hudson chipsets as of 1.2.001.263.
Audio Stutter / Slurring occuring during playback of video/audio:
http://forum.lenovo.com/t5/X-Series-ThinkPad-Laptops/x120e-Stuttering-Audio/td-p/389023
This issue can be reproduced (at least on my X120e) by waking the X120e after putting it to sleep. The symptom is the audio repeating a sound over a span of a second or two during playback and is quite noticable.
Solution:
uEFI Bios version 1.11 seems to deal with the audio stuttering issue. So far, results lead to positive outcomes.
Old Solution:
PWMTR64V.DLL that is loaded at Startup seems to be causing this issue. Disabling it from launching when starting up seems to cure the Audio Stutter (even after waking up from sleep which was seen to be a pretty reliable way to get the issue to repro). Start Menu > Launch MSCONFIG from the Search Bar > Select Startup Tab from the System Configuration window > Uncheck Thinkpad Power Manager > Restart.
This does not seem to turn off the power manager application itself so settings in Power Manager can be saved and it seems to still be in effect. However, opening up Power Manager from the notification / taskbar can cause audio stuttering and mouse movement slowdown while it is launching and/or when applying settings. This is only temporary and is gone when Power Manager is closed. (Thanks kns7977 for the find)
Pending to see if those who uninstalled Power Manager are able to turn off the offending startup .dll.
Mouse seems to stutter or stay in place for a moment when moving:
This seems to be caused by the same issue causing the Audio Stutter / Slurring. At least at this time, the cause of the issue and solution seems to be the same.
Emulating Middle Mouse Button with Trackpoint:
One can set up the middle button between the left and right click button for the TrackPoint to act like pressing a middle mouse button on a standard mouse by changing the scrolling type to Smooth instead of the default Standard.
Control Panel > Hardware & Sound > Mouse > UltraNav Tab > Setting for TrackPoint > Setting for Choose Scrolling or Magnifying Glass Function > Smooth.
Trackpad's two finger gesture being hit or miss:
The trackpad's two finger scrolling is very hit and miss.
http://forum.lenovo.com/t5/X-Series-ThinkPad-Laptops/X120e-Touchpad-issues/td-p/393751
Solution: Turning off Gesture Filtering may alleviate the problem. As mentioned in http://forum.notebookreview.com/lenovo-ibm/561751-x120e-owners-thread-24.html#post7323293, it seems that the Gesture Filtering is counteracting any sort of two finger input.
Get to Mouse Properties by Fn + F8, select Manage Settings. At Mouse Properties, select the UltraNav tab > Settings for TouchPad. Expand the Smart Check Settings, highlight Gesture Filtering, and uncheck the Enable Gesture Filtering box and Apply.
Screen flickers lines:
http://forum.lenovo.com/t5/X-Series-ThinkPad-Laptops/x120e-Flickering/td-p/389523
Had this issue occur on me once, but never seen it happen again. Unsure what caused or cured it.
Solution:
If the flickering is occuring, a restart is all that is needed to alleviate the problem. Haven't tested if hibernation fixes it, but neither sleep nor turning off the screen with the Power Manager dealt with the flickering.
3-Cell Battery mentioned as a 40Wh in the Order Page of Lenovo X120e when it is actually rated as 32Wh according to Power Manager:
http://forum.lenovo.com/t5/X-Series-ThinkPad-Laptops/X120e-3-cell-40Wh-battery-reported-as-32Wh-by-P...
Yeah...
Solution:
Accept that it's a 32Wh you will get when selecting 3-Cell or go for the 6-Cell if you want more than 32Wh.
2x2 ABGN Driver from Lenovo triggering Error Code 10:
http://forum.lenovo.com/t5/X-Series-ThinkPad-Laptops/X120e-ABGN-Driver-issue-in-Windows-7-Pro-x64/td...
The Wireless driver from Lenovo's site seems to not work with the 2x2 ABGN wireless when installed on a fresh copy of Windows 7 x64.
Solution:
Not really quite a solution, but one can bypass this by either installing the 32-bit Windows 7 and installing the 32-bit driver, or using the factory recovery disc to install 64 bit windows 7 to have it install drivers that work for x64 windows 7.
X120e bluescreens after installing LAN Realtek 7.26.902.2010 drivers from Lenovo's Driver download site.
http://forum.lenovo.com/t5/X-Series-ThinkPad-Laptops/x120e-bluescreen-when-installing-lan-drivers/td...
The drivers doesn't seem to work and it causes a bluescreen on fresh installed Windows 7 x64.
Solution:
As Clicq suggests, Realtek's own drivers from http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=13&PFid=5&Level=5&Conn=4&DownTy... seems to deal with the issue.
Screen quality on the X120e:
http://forum.lenovo.com/t5/X-Series-ThinkPad-Laptops/x120e-poor-LCD-quality-viewing-angles/td-p/3945...
The quality of the screen on an X120e is below expectations.
This is common with low-quality TN panels not helped by glossy displays. My personal X120e screen likes to bleed certain colors of red.
Solution (not really):
One can use the Windows 7 built-in color calibration tool to adjust the colors to make it more tolerable. Adjusting your own viewing angle in relation to the screen might deal with some color issues (hard to figure out what's the correct viewing angle because of TN panel's small range of optimal viewing angles). Also, changing the refresh rate to 60Hz may deal with some headaches due to the screen (as it did for me).
HDMI Overscan to HDTV issue:
http://forum.lenovo.com/t5/X-Series-ThinkPad-Laptops/HDMI-overscan-to-HDTV-issue-on-x120e/m-p/395335
There is a black border when outputting to HDTV through HDMI.
Solution:
AMD's CCC by default sets a specific value for overscan / underscan. One can http://forum.lenovo.com/t5/X-Series-ThinkPad-Laptops/Output-to-TV-via-HDMI-port-black-border-on-the-... while the device is connected via HDMI (the option is hidden if the HDMI port is not used) and adjust the slider to an acceptable value.
Skype asserts after 10-20 seconds of video chat:
http://forum.lenovo.com/t5/X-Series-ThinkPad-Laptops/x120e-Skype-quits-after-10-20-seconds-of-video/...
When doing a video chat, the video feed will freeze and then skype will crash to desktop.
Solution:
Version 5.3 of Skype seems to be the culprit. Until Skype itself is fixed, one can use Skype 5.2.60.113 from http://www.filehippo.com/download_skype/changelog/9465/ to bypass this issue. Just reject any offer to update to 5.3 after installing 5.2, for now.
If there is anything I missed, please respond and I'll update this post with new information. These are the ones that I have encountered so far with my Lenovo X120e. Don't get me wrong, I like my X120e... it's just been a "learning" experience lol

Split x2 - Touchpad issue after upgrading to Windows 8.1

Hello,
I bought this Split x 2 a week ago and it came with WIndows 8. Everything was working fine until I upgraded to WIndows 8.1. Now my Touchpad will freeze some times and I have to log out and log back in to my profile to unfreeze the touchpad other times I can get it to unfreeze by resetting the release touch screen buttom.
I called HP customer service and they said it was a Microsoft issue and transfer me to them. Microsoft said it was a hardware (HP) Issue and that i needed to go back to the store where I bought it
(BestBuy). I took it back yesterday to BestBuy and they gave me a knew one. I did the same thing and upgraded to Windows 8.1 and touchpad issues is back. So pretty sure is not a hardware issue.
All windows updates are completed
I checked the Touchpad's Driver and it is up to date.
NOTE: I plugged a wireless mouse to my laptop and when the touchpad freezes the wireless mouse still works.
Does anyone know a fix for this issue? Everything else works great on the laptop is just very inconvenient when you are working and you have to log out to get your touchpat to work again.
Any help would be appreaciate it.

Well you gave me a great idea. So the same thing happened to me, the install failed due to the driver signature. I uninstalled the current driver, then turned off the feature that requires signed drivers and installed the driver. Everything is working so far.... the only odd thing is it doesn't show the driver any where. I am going to try a few other things BUT the mouse hasn't stopped working for a good half hour.

Help with touchpad issue!!

After looking on the web, I realise this is not an isolated issue and many people have had it.
*Problem in bold if you cant be bothered reading everything :)*
The problem I have is with the touchpad on my Macbook Pro. This morning my mac had a funny turn and kept freezing soon after loading up the desktop. I could move around with the touchpad but not do much else, so I restarted and plugged in an external mouse and this worked. So I was really annoyed (My TV had decided it was going to pack in aswell this morn) and was about to hurl my mac at the TV to teach them both a lesson when my TV fixed itself and my touchpad gained some usability.
This is the strangest part - to start with the touchpad could double click - but you had to use three fingers instead of two, it could three finger swipe - but with four fingers and 5 fingers for expose!! But I couldn't single click. *Now, However, I can do everything on the mac by touching the pad but there is no response when I physically click the pad down. You can hear the click but nothing happens, unless you press really hard, in which case it works 1 out of 5 attempts.*
My macbook is only four months old, so I'm presuming it is still under warranty? However, I didn't buy directly from Apple but instead from Currys, will this make a difference. I would just take it in to an Apple Store but the nearest one is about 1.5 hours away and I have no car So I don't want to waste money and time getting there only for them to turn me away/ have no warranty!!
Thanks in advance for any help,
Adam

Should they fix it for free? I
If the unit is under a year old or you purchased the 3-year AppleCare plan, then yes.

TX2Z - 5 days of use: my initial impression, issues and need for advice

Hello All,
I have had my TX2Z for a complete 5 days now. Prior to purchasing, i had a Dell 700m for almost 4 years. When I bougt the Dell, i got it loaded with a 2GHz Intel processor, 2GB RAM, 120GB HDD, XP Pro, etc. It is a brilliant machine and I really enjoyed it...it was good to me and I really can say I never had any issues with it. I took care of it and it returned the favor. I upgraded to Vista Business back in November and it was still great. In fact, I still think it out performs (in terms of speed and stability), most other new laptops owned by my collegues. However, for work, i really needed a tablet and although i read some bad reviews about the TX2Z, i read many more good reviews. So a couple of weeks ago, I called them and ordered a pretty loaded one. I have the 2.4GHz processor, 4GB RAM, Vista Ultimate 64 bit, 250GB 7200 RPM HDD, etc. I assumed it would be quite fast since reviews i read stated the standard 2.2GHz processor was sufficient.
So it came in last Tuesday and I began the migration process. I did a lot of reserach online about what bloatware to remove and did so. Between work and time at home, it took me 2 days to get everything to migrate over from my Dell and install my applications. I partitioned the HD and put my data on the new partition. Outlook migration was quite bothersome to say the least.
I've had a lot of strange issues and had to do a lot of reserach to find fixes but it seems random new issues pop up from time to time. They may be small, but i'm not too technical so I just expect things to work as they did on my Dell for so long.
1. I feel its very slow. When you click on something, like when going through email in Outlook, the email just doesn't show up in the preview pane right away...it takes anywhere from 3-5 seconds...something that was instant before. Same thing when doing many other things...I feel like even web browsing has slowed down. i have defragmented, cleaned, optimized, etc...still inadequate.
2. I feel its very delicate. I've had it freeze on me a couple of times and today, i booted up and logged in and it went to some other profile on the computer with a message stating that there was an issue with my user profile. scared me, but i restarted and then it booted into my profile. then when i booted up again later, it did the same thing! thank God this time it was fine on the first go, but now i feel i have to worry about that every time i boot up...not a cool feeling.
3. I'm trying to get used to the tablet portion of it, but i feel it can be a little annoying sometimes. i won't complain much about it though because I think i need more practice first. i can write pretty well, but drawing on teh screen, the main reason for my using it, isn't that friendly...i always have to put the screen up to access teh keyboard and touchpad to really have what i want happen...i can't just do everything from the tablet.
4. heat: ive seen many people complain about this...it really is annoying how much heat comes out of this thing. i have to keep a folded cloth on my lap so it doesn't bother me.
5. fan: again, another concern i see expressed a lot...very annoying so i try to use only when unplugged and charge when i'm not using it. for the heat issue and the fan...i don't understand why HP doesn't use something else...i mean in this day and age, when they know this is a known issue on other models, why would they use it again?
so that's pretty much all i can think of now. i do like a number of things too, but i really would like advice on the above. i know a lot of you will say just to wipe everything out and start over, but is there any other way to run some tests to see what the issue is? i really don't want to go through another 2 day process. also, if i have to do this, is there a better way to migrate programs and data to an external HD and then back? i just moved my data to an external HD and basically just installed software using discs and internet downloads...took forever!
what about these recover discs i hear a lot aboutt? if i make them now, will they keep all current data and configurations too or just the original OS?
sorry for the long post, but would like some help on what to do. i need to have some confidence built in me about this machine and some reassuracne that i should be happy for the next 2-3 years. TIA.

hmmm this is actually a not bad idea!

Hp G62 cold touchpad issue

I have an HP G62 a20sA laptop and its developed a fault. The touchpad is very intermittent, for example if i go to click on something the single click or double click wont work, or if i go to move the pointer it will judder across the screen.
The wield thing is that this only happens while the laptop is cold, as in when i have only just turned it on and the laptop plastic is cold. After a while of the laptop being on and the area where the touchpad is gets warmer the pad becomes more responsive.
If the touched is particularly bad I can sometimes lay my hand across the whole pad for a while warming it up and it will become more responsive for a while, almost as if it needs to be warm for my finger to be recognised.
I dont think this is a driver issue as the driver is the most up to date driver.
My brother has the same laptop but slightly differnet spec and his is starting to develope this fault too.
Anyone else had this issue and or have any suggestions.

HI Timhannah1988:
Thank you for your post. I will do my best to aid you in this endeavor!
I assume that the laptop is stored in normal temperatures and not in a very cold room. I am providing you documentation on "Using and Configuring the TouchPad (Windows 7 and Vista)" click here. You could also run the HP Support Assistant click here to look for updates and help resolve issues. Please let me know if this has helped.

Satellite P300-1AN - Touchpad issue with AC adapter

I've a Satellite P300-1AN notebook and since the beginning (two weeks)
I have a touchpad issue: it is not immediately responsive and the pointer trembles when touching the pad. Very often it freezes for just one or two seconds.
This is VERY annoying. A USB mouse works perfectly.
I tried reinstalling ALPS drivers, tried Synaptics ones, tried just Windows Vista drivers: no way.
Now I have found the reason: this issue is present only when the notebook is powered by AC adapter.
With battery the touchpad is perfect.
I contacted Toshiba Service and thay said that they won't change the AC adapter if I don't try before a complete system restore!
Isn't it simpler just try with a new adapter and only then, if the problem persists, try more drastic procedures?
Has anyone had this same issue?

> I contacted Toshiba Service and thay said that they won't change the AC adapter if I don't try before a complete system restore! Isn't it simpler just try with a new adapter and only then, if the problem persists, try more drastic procedures?
The point is that your notebook should be always checked using the Toshiba factory configuration.
Why? Because the ASP wants to be sure that this issue is not related to a software problem (compatibility issue with 3rd party applications). The software issues are not covered by warranty.
Furthermore the ASP will always recover the notebook before checking any hardware parts for a malfunction. Therefore you should always backup your data from the HDD before you will send the notebook for checking.
I would recommend to reinstall the OS using the Toshiba recover disk and then check if the issue would appears.
If yes then you can contact the ASP again and could provide all details which are necessary for an technician.
Bye

Jumpy touchpad when I scroll after some updates on Thinkpad S440

Hello everybody
Yesterday I ran some updates and since then I have a touchpad issue. It automatically jumps when I scroll down or up. Sometimes, when I scroll down a PDF or a webpage it goes automatically to the end.
This is a very annoying issue. My Thinkpad is new and clean and this issue came after some updates.
I am thinking the problem might be due of:
- Synaptics UltraNav driver update (16.6.4.38)
- Auto Scroll Utility (2.10)
I don't know a lot, if someone has the same issue or know the solution I would be nice to add your experience
Thank you.

I also agree that it would be nice for a warning if the updateConfig.xml file does not exist, or if it is not formatted properly. For example, I change my app ID before publishing and forgot to update the config file resulting in me having to submit yet another version - from a human factors standpoint, these errors will occur from time to time so any help on the machine-side would be useful.
Additionally, it would be nice to have the option to remove/hide any apps that have been withdrawn from the 'Manage' screen.
All-in-all though, I think you guys are doing a great job!

Hi Tomsconi,
Thank you for visiting the HP Support Forums and Welcome. I have read your thread on your HP ENVY m6-n012dx Notebook and having issues with the Touchpad and Touchscreen. Here is a document on how to troubleshoot the mouse and Touchpad sensitivities. Here is a link to The HP Support Assistant. The HP Support Assistant will help with the drivers and software that are on your machine now. Here is a document on an update download for Windows 8.1 that might help. It is a recommended update for Touchpad issues.
Hope this helps you.
