Strange trackpad issue

Hi
Last weekend my Synaptics trackpad started to behave odd, during boot up the mouse pointer is in the centre of the screen, then as the computer loads up it starts to move all over the screen by itself.. If I try to move it using the trackpad it will move in a straight line left to right or visa versa.. but it is difficult to move in any other direction.
If I do move it, as soon as I let go it moves backwards and forwards on it's own....
I have unistalled the device drivers and software, reinstalled this using recovery manager, then updated to the latest verson, but it still behaves odd.
If I let the notebook boot up, leaving it for a few minutes it will be OK.
It is as iff the trackpad is loading last... I have also tried cleaning the trackpad...
The notebook is an HP Envy 17-1050ea with Windows 7 64 Bit.
Any suggestions...
Stuart

Strange Trackpad Issue - is it a problem?

Hello all,
My DVI p/book is more or less three years old now and has never given me any significent problems. As a long term apple user i have never been more pleased with one of their machines. The new macbooks are very impressive, but this laptop has served me so well i fully intend to keep running it until i need to upgrade.
A strange problem has started occuring - well, it's not really a problem more of an annoyance and i'm wondering if it's something to worry about. when i put my finger on the trackpad to tap or make a gesture, it makes a load "click" noise. it only happens as i put my finger on the trackpad.
resetting the trackpad with the palm of my hand stops this for a few minutes, then it starts again.
should i be worried? is my trackpad on the way out?
many thanks for any help

Hi, Rich. In two years of reading every new post in the Tibook forums nearly every day, I don't recall ever seeing the behavior you describe reported before. Consequently, I have many more questions than answers for you.
Does the sound come from your PB's speakers? Does it stop if you mute them? Can you hear it through headphones, when headphones are connected?
Is it a static discharge? Can you see a spark accompanying the sound if you turn the display brightness all the way down and then touch the trackpad in a dark room? Do you feel any "electric" or tingling sensation when you touch your trackpad or any other part of your PB?
Does it make any difference how firm the contact is between your finger and the trackpad — i.e. if you sneak up on it very gently and barely touch it, is the sound the same as if you tap it firmly? Is there any physical "give" in the trackpad to suggest that the sound is produced by physical movement?
In the absence of any similar reports from others, I have no idea whether there is any software you might have installed that would cause this behavior. You might try creating a new user, logging in as that user and seeing whether the behavior persists. If it doesn't, that would suggest that you have some preference or setting or third-party software — peculiar to your normal user account — that is causing the behavior.
Please post back with further details. This is very interesting.

Weird trackpad issue. OSX?

This is strange and possibly a tad petty, but I cant get my trackpad tracking sensativity anything less than full. Whenever I go into System Preferences to change it, it always sets itself back to full when I close the window. Is there some sort of memory file that resets it when I close the window? Ideas?

Are you having problems with your trackpad while typing? My pointer moves around like crazy while typing. The four corners are suppose to be dead while typing but arent!
I have had two SR MBPs captured with this issue and other issues! The thing that piXXed me off was that with the first capture they ignored the trackpad issue so in goes the second one.
I feel so used...

Strange performance issue with 3510/3511 SAM-FS disk cache

Hi there!
I'm running a small SAM-QFS environment and have some strange performance issue on the disk storage part, which somebody here might be able to explain.
Configuration: one 3510, dual controller, RAID-5 9+1, one hot spare and one disk not configured for whatever reason. The R5 logical drive hosts a 150GB LUN for SAM-QFS metadata (mm in SAM-FS speak) and a 1TB LUN for data (mr in SAM-FS speak). Further, there are two small LUNs (2GB, 100GB) for some other purpose. Those two LUNs have nearly no I/O. All disks are SUN146G. Host connection is 2GBit, multipathing enabled and working.
Then the disk cache became too small, and the customer added a 3511 expansion unit with SUN300G disks. One logical drive is a RAID-1, 1+1, used for NetBackup catalog. The other is a RAID-5, 8+1, providing two LUNs: 260GB SAM-FS metadata (mm) and 1.999TB SAM-FS data (mr).
For SAM-FS, the LUNs form two file systems: one "residing" in the 3510, the other "residing" in the 3511 expansion. Cabling is according to the manual and checked several times by several independant people. Operating system is Solaris 10, hardware is a V880.
The problem we observe: SAM-FS I/O on LUNs on disks inside the 3510 is fine. With iostat, I see 100MB/s read and 50MB/s write at the same time. On the SAM-FS file system which is running on the two LUNs in the 3511, the limit seems to be at 40MB/s read/write. Both SAM-FS file systems are configured the same in regards of block size.
In case I have activity on both SAM-FS file systems, I see 100MB/s+ on the LUN running inside the controller shelf and another 40MB/s on the disk runnin in the 3511 expansion chassis. So, the controller is easily capable of handling 150MB/s.
Cache settings in the 3510 controller are default I think (wasn't installed by me), batteries are fine.
Is this 40MB/s we experience a limitation by the expansion shelf? Don't think so. Anybody has any ideas on this? What parameters to check or to change? Any hint appreciated. I can also provide further details if needed. Thank you.
wolfgang

SUN300G disks sound like 300GB FC disks.
Depending on how many files are in the SAMFS file system, sharing the mm and mr devices on the same RAID array can be a pretty horrible idea. In my opinion and experience, it's almost always better to NEVER put more than one LUN on a RAID array. Period. Putting more than one LUN on an array results in IO contention on that array. And large, unnaturally configured (9+1? Why?) RAID arrays will have problems from the start.
What are the block sizes used on the RAID arrays? It wouldn't surprise me to see that the RAID array on the expansion tray has a very large block size. Larger block sizes are, in general, not better. Especially for SAMFS metadata - which IIRC is something like 8k or 16k blocks.
I suspect what is happening is most of the metadata updates are going to the mm device on the new array, contending with the IO operations on the file data.
How much space is left on each mm device? What does "iostat -sndxz 2" show when you're having the IO problems?

Strange import issue .. no longer works in 2.6 or Beta 3

Strange import issue.
I use LR-2.6 everyday but have only played around with the LR-3 for a limited amount of time so the other day I decided check it out and tried to import a handful of RAW(canon) files on a SDxc-8g card via a USB card reader. I set it up to copy and convert to DNG, apply a few keywords and Metadata but when I tried it acted like it imported the first image and then froze. Card reader lights stopped blinking and just stayed on, program task bar doesn’t show any progress, not even for the first image. I then went to the folder that I was going to have the images copies to and it contained a file of the first image, but there is no indication that LR-3 even created it and it doesn’t show up in the catalog. When I tried to close out LR-3 is popped up the “in the middle of a task warning” so I just closed the program and tried it a couple more times to no avail.
So I though o well I will just open up LR-2.6 and import them from there, guess what now LR-2.6 does the exact same thing!!
I thought maybe my card reader was a POS but I was able to drag all the files to a new folder on my desktop and import them from there, nope. Tried rebooting a couple times, even opened a new catalog to test with, in both LR-2.6 and LR-3 and neither will work..
I am stumped any ideas?

Thank you for everyone's assistance
I actually figured out what the problem was, like most issues it comes back to operator error, it seem I had inadvertently chose a "rename file on import" template that I had set up to name the files based on a custom fill-in field in the Meta Data, I normally only used that template when I was exporting images that had been completely edited, so being these images were new imports that field was blank, hence it would import the first image and then do to " don't import subjected duplicates" being checked it would just stop the import process.

Trackpad issues on Macbook Pro 15"

Hi! I'm experiencing trackpad issues with a Macbook Pro 15" Model A1286. The battery had recently swollen after a long and productive life of about 5 years. Assuming this was a fair life/usage for a battery I have ordered a replacement from Apple.
While waiting for the replacement battery and following advice from other users, I removed the battery and have the power lead connected to prevent damage from the swollen battery. However, the trackpad now only appears to work the cursor movements around the screen and does not register clicks without the battery in place - it's as if it's got nothing to push against. I'm guessing that the swollen battery may have caused damage to the trackpad, but won't know until the new battery arrives.
Do I just need to be patient and wait for it's arrival or are there any suggestions of how to rectify this please?
Thanks in advance for your advice.

Trackpad issues on Macbook Pro, new June 2009

I have been unable to resolve a trackpad issue that began this afternoon on my Macbook Pro. The computer was new in June. I was playing an online computer game, and it seemed that drag was locked on even though I hadn't changed any settings. Movements of the mouse dragged the window. The drag would not release with 1 click, 2 finger click etc. When I tried typing, the letters selected and replaced as soon as I typed new ones. After several restarts with the same behavior occurring, I reloaded the Snow Leopard 10.6 OS. I originally installed it about 2 weeks ago, and it has been working fine until now. After the reinstallation, the trackpad will not register most clicks of the trackpad. It will register taps, but it refuses to let the user click and drag. I have Microsoft Vista installed in Boot Camp and the trackpad is operating with the same glitches on boot camp. Clicks of the trackpad do not register most of the time. If they do, I have to click very hard, and even then it doesn't always work.

Strange Catalog Issue or bug. Help, photos disappeared help?

My images disappeared in the catalog. They are not missing, they are just not visable. I think there is a bug in the Fliter section.
Let me explain. I have one Main folder with 5 Sub folders. All those folders contain random amounts of images. (i.e. the path would be... Photo/2010/BeachShoot, or Photo/2008/PartyPics... etc).
I imported 5 years of images, hence 5 Sub Folders. I was randomly flagging images to be rejected with the 'x' key. Basically routine maintenance... flag so many, then call up only the rejected photos in the grid view, select all, then delete. Remove the Flag Filter... repeat process over and over... Basic, simple work...
Now... doing the exact some thing.. I removed all Flag filters and my images are no longer appearing in the catalog. I tested, by turning on flags, off flags.. etc. The images did not accidentally get deleted. I checked my hard drive location. Images are there. I rebooted the machine, I opened up another catalog, to trick it back... did not work. I tried to re-import the images.. but it says they are already in the catalog.
Strange part: On the Left Sidebar window, under Catalog "All Photographs" it shows the correct number of photos in the catalog. However... the strange part... Under "Folders" in the Left Sidebar beneath Catalogs my Main Folder shows "Zero" number of images. But, if I click on a sub root folder where the images reside, they number changes from Zero to the correct number of images and my images reappear on the screen as normal..
The work around... click on every subfolder...
The solution... Unsure? Help!

What happened to the huge thread on trackpad issues?

There was a huge thread I has a subscription to with hundreds of replies and thousands of views on the problems especially with Early 2008 MacBook/Pro with erratic cursor movements, hypersensitive scrolling and lack of tap-functionality with the Bootcamp drivers.
I can no longer find the thread nor am I still subscribed. Yet except for a patch that is only for Late 2008 laptops and a hacked version of the patch from a user that never fixed any of the problems on my machine, there has no been no updated driver from Apple.
What's the deal?

What problems with trackpad issues? There are none! Haha... Just Kidding...

Strange Printing Issue With New HP & Pages

Hello!
I have a very strange printing issue with a new HP printer. I have written pages documents heavy in Texts which are located within tables. The documents print fine on a Cannon and Epson printer and look great but when I print the document on my new HP Laserjet Pro 400 Colour M451nw some of the text on some rows come out of the printer looking like they are bold / slightly fuzzy. This only happens with some of the rows of text, not all of them. The font is the same in every row with the same format.
You can see this in the attached image. The first line (Thanks very much) has printed correctly but the subsequent lines look bold / slightly fuzzy.
After a lot of testing the only way I can resolve this is if I copy the content into a new pages document and only then it will print and look ok with the HP printer.
This must be a problem within my origional document. I would simply copy and paste everything into a new document however this would take a very, very long time (over 5 years of work producing teaching materials and over 100 documents and thousands of tables and formatting that cannot be copied and pasted).
Also, on other printers you can see the lines seperating each row of the table. These lines are not visible on the HP print outs, even when the table is copied into a new document.
Has anyone come accross an issue like this before? Is there a way I can fix this without creating a new document? Do I need to get a new another new printer (the 4th printer this week!)?
Any advise, wise words would be greatly apprechiated!
Thanks!

Sorry, Fruhulda. After 4 hours on the phone with Apple care they are taking this issue further themselves. It seems to be a problem with our pages document and the compatibility with certain drivers. We have still not gotton to the bottom of it and Apple are going to get back to me when they have an answer.
We also worked out that the issue only happens when you print via Ethrenet & USB. Printing via Wifi is ok and there are no quality issues.
Very Strange!

Trackpad Issue - Please Help!

Hi there,
Hope you can help me out here.
I've recently purchased a 15" i7 Macbook pro. The machine is but 3 weeks old &, of course, very well looked after.
A few days ago, the built-in trackpad started behaving eratically. Cursor moving by itself, not responding to touch, clicking and opening things involuntarily. Not good at all. Many users seem to have had this exact same issue.
These problems seemed to miraculously stop after a few re-boots and possibly a software update? I really couldn't tell you what resolved the problem.
Unfortunately I now have a totally different problem.
There is a thin, possibly 8 to 10mm horizontal strip across the centre of the trackpad that no longer responds to touch. If I move my finger from the botom of the trackpad upwards (or vice versa), the cursor will stop momentarily as it passes over the horizontal strip. The buttons are fine and the rest of the trackpad is fine. For the moment, I've increased the cursor acceleration so that I can at least navigate round the screen with a smaller area of the trackpad. USB magic mouse seems to work fine.
If anyone else has experienced this &/or found a solution for this issue, please help me out here. I have rifled through endless threads about MBP trackpad issues with little success & do not live close to an apple store/genius bar.
This is a 3 week old machine that cost me a small fortune. To be getting software/hardware issues so early on in it's lifespan is really rather worrying for the future.
Appreciate your help here.
J

I'm not sure what caused this, but I extended my lunch break and drove the machine down to the Westfield apple store. I didn't have an appointment with the Genius Bar but I managed to persuade one of the staff to speak to a technician in the workshop. She came back into the store and told me that they had replacement trackpads and that , considering the machine was only 3 weeks old, the technicians kindly sandwiched the repair into their timetable at zero cost. 2 Hours later, I now have a perfectly functioning trackpad/machine.
I can't thank them enough.
My only gripe is that I couldn't speak to a technician to find out what the problem was, how they resolved it or what causes these issues for future reference. Understanding why these problems occur often helps to build your own framework of understanding. Most of the threads i've read about trackpad issues are largely unresolved with people only speculating the problem/solution.
The initial issue I had with the trackpad's erratic behaviour seemed to be a well known problem that many are associating with a trackpad firmware update. Unless by pure coincidence I had an immediate & major hardware fault after it, which is unlikely, my personal guess is that the two issues were related.

[solved] Strange Audio Issue

I am experiencing a strange audio issue with my Intel-HDA ICH7:
# lspci -v
00:1b.0 Class 0403: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 01)
Subsystem: Hewlett-Packard Company Unknown device 30a5
Flags: bus master, fast devsel, latency 0, IRQ 22
Memory at d2400000 (64-bit, non-prefetchable) [size=16K]
Capabilities: <access>
when I installed Arch linux the first time a mounth ago on this computer, I had a sound problem that was solved in a very strange way.
Everything worked fine until a week or so (I believe from Alsa 1.0.12). Now sometimes sound works and sometimes it doesn't. For example sometime I boot the computer and have no sound, then I reboot it without doing anything, and then sound works.
I have tried messing with the modprobe.conf:
# /etc/modprobe.conf (for v2.6 kernels)
# --- BEGIN: Generated by ALSACONF, do not edit. ---
# --- ALSACONF version 1.0.11 ---
#alias snd-card-0 snd-hda-intel
#alias sound-slot-0 snd-hda-intel
# --- END: Generated by ALSACONF, do not edit. ---
#options snd-hda-intel model=F1734
options snd-hda-intel model=z71v
options snd-hda-intel position_fix=1
but it was useless. If I put back the modules in rc.conf everything is worse: sound doesn't work at all.
A diff between lsmod in a "working boot" and a "without sound boot" showed that the same modules where in kernel memory.
A diff between dmesg showed this difference:
< hda_intel: azx_get_response timeout, switching to single_cmd mode...
was present in the not working boot. This line is absent in a working boot dmesg.
The only way to make the sound card working everytime is to remove the snd* modules load from the boot sequence and load the modules "by hand" after the login.
Any ideas?
PS : If something is unclear due to my poor English please tell my and I'll try to explain it better.

phrakture wrote:snd-hda-intel is screwed up - on my thinkpad I had to go into the bios and enable the modem for sound to work. Oddly enough, the modem was off by default.
Also, mine has no PCM listed, I need to use "front" as my PCM level... not to mention the UI is way off with 'tpb' (if you have a thinkpad)
Yes it's not an Arch Linux related problem: I had problems with Debian (Etch and Sid based distros like ubuntu) too (but there I had no modprobe issue on the init sequence. Maybe is a problem of shared IRQs, but I have to study the existing documentation as I am a newbie). The difference is that Arch is simple enought for me to try something like modprobing "by hand" in the init sequence. PCM seems to work, however the volume is very low and I have found no way to make the mic work. Under Mepis I was able to make it work only if I plugged it in windows xp and then reboot into Linux. But I can't try it with Arch as I have erased the windows partition...
I will try the new kernel, study the documentation and then report. Hoping this will be usefull to others too.

Very strange backlight issue

I have a 600mhz (16 VRAM) iBook that I'm trying to fix for a friend. It has a strange backlight issue. Everytime the ibook is started, it chimes, and shows the screen (bright and perfect), but as soon as 9.2 starts to load, the backlight goes out. It is not intermittent, it happens at the exact same time every time I start it up (right when the progress bar starts to move). I reset the PRAM, which caused the computer to now look for a startup device, so all the extra time it takes search, the backlight is fine. Here's what I've tried.
In firewire mode, the backlight never comes on
With a hardware test disc, the backlight never comes on
Reset the PRAM (several times)
Reset the PMU (several times)
Any ideas out there?

As an update, I tried a Mac OS 10.4 startup disc which seemed to work, and the backlight came on with no problems. The machine did freeze on the welcome screen right after I selected english as the language of choice. So I tried a 10.3 disc which yeilds a kernal panic of "Unable to find driver for this platform: "PowerBook 4,3". After this, I tried a 9.2.2 disc which boots (takes 20 mins to boot) and when I try to load the installer I receive a "this program can not run on this machine", and it closes. This really seems like a strange problem. Any ideas?

(Not a) Trackpad Issue

I don't know what to call this issue and it's a sort of trackpad issue but not really. When I rest my palm on the sides of the computer off of the trackpad (no my thumb and no part of my hand is on the trackpad) I can still select things as if I were using the trackpad or as if I hit ctrl-select. I can even do it one fingered.
The real problem arises when in the middle of typing my hand hits on those areas because it will sometimes select whole pieces of text and then I'll hit a letter or space and it will wipe it all out. I had this problem when I first got it but I assumed it was because I wasn't used to such a wide trackpad. Others have had this problem when using my mac but I've chalked it up to new mac users. However after the problem getting worse recently I realized it's not me.
The trackpad isn't fabulous in general and I can't always get this straightened out. I couldn't get an appointment with the genius bar until Friday and the people at the Apple Store thought I was crazy and kept asking if I had some part of my hand on the trackpad. I happened to experiment when I was in Best Buy and it appears their model does it too but isn't nearly as sensitive as mine is.
I would love to know if others have this and if you've found fixes (don't want to give up my laptop, I need it, for a repair). Also what would I search for for others with similar problems.

P.S. I can't move the arrow around the screen with the areas not on the trackpad I can only select in these area.
