Option to disable UltraNav (touchpad + trackpoint) when external mouse is connected

I grabbed the 5/2011 drivers for UltraNav from the Lenovo site and it appears that an option 'to disable the integrated pointing devices when an external pointing device is present' does not exist, or at the very least I can't easily find it. Please please please please tell me I'm simply being dense and this behavior is very easy to enable.
Seriously, the 5-year old Dell drivers I had with my old machine did that, and this is driving me BONKERS.
Alternatively, if what I'm doing here is feature-requesting, I'd be like 50% there if I could Fn+F8 and have an option to kill both the touchpad and the trackpoint - alas, I can disable 1 or the other BUT NOT BOTH WITH THAT OPTION. Can I really not disable both?
Lenovo W520, Windows 7 Professional 64-bit.

Even though it passed some time from first post I'm writing a solution for auto disabling UltraNav touchpad and trackpoint when external mouse is connected.
I have Lenovo L530 that doesn't have shortcut on keyboard to disable Elantech touchpad so after a driver update (from about 20 March 2013) I tried to find a solution again -now with success.
To auto disable touchpad when external mouse is connected you have to set value in registry editor here is procedure (for Windows 7 procedure for other Windows editions is similar or same):
Click Windows type in regedit and run it.
Navigate to HKEY_CURRENT_USER\Software\Elantech\OtherSetting. (If you can't find Elantech\OtherSetting in HKEY_CURRENT_USER navigate to HKEY_LOCAL_MACHINE\Software\Elantech\OtherSetting.)
Find DisableWhenDetectUSBMouse double click it and change value (from 0) to 1, hit OK.
(If you don't have DisableWhenDetectUSBMouse in Elantech\OtherSetting create new DWORD with name DisableWhenDetectUSBMouse and set value to 1.)
Restart computer.
I hope someone still find this helpful.

How to disable UltrNav when external mouse connected

Is there a way to have the UltraNav turned off automatically when an external mouse is connected?
When typing it’s too easy to inadvertently touch the UltrNav and if you’re not watching find you’re typing in a different location, so we like to turn it off. But when I need to quickly access the laptop I would like to use the UltrNav and not have to find and connect the mouse.
I can turn it off/on through the control panel/system tray, however it’s near impossible to turn on without a mouse.
Our users have gotten use to this feature in other laptop brands but according to the Lenovo help desk it’s not available.

Hi, GDodman
Unfortunately, I don't think this option is currently supported on Lenovo Think brands. I did some research on the topic and attempted to change the settings of UltraNav, but was not able to find this function. If you find that UltraNav is too easy to inadvertantly tap while typing, then I would recommend changing the sensitvity to a lower setting to reduce future misclicks and random movements.
Best of luck,
Adam

Disabling Ultranav TouchPad keeping TrackPoint

I have a Ultranav keyboard and I want to disable the Touchpad but keep the Trackpoint. I'm using the latest driver (noted below), but it doesn't have an Ultranav tab in the Control Panel. I've searched the net and can't find any real solution. Has anyone tried physically disconnecting the Touchpad? Is so, some tips on doing that without destroying the keyboard would be much appreciated. Thanks.

Can't disable touchpad when external mouse connected

Hey guys,
OS: Win7 64Bit
Product : b0p18pa#ab4
Model: dv6-7007tx
The only way i've figured out a way to disable the touchpad is to uninstall the PS/2 compatible mouse in device manager. (which requires a restart) to come into effect and is reinstalled after the next restart afterwards.
the touchpad is SO sensitive it makes it extremely aggrivating to type as i keep tapping the pad with my palms.
any insight would be fantastic.
cheers guys.

Hi,
Please try:
   Control panel > Mouse > ClickPad Settings
   Tick Disable internal pointing device when .....
   Click Apply
Regards.

Windows 8 and Canvio Desk 3TB: System will not boot when external hdd is connected

http://h30434.www3.hp.com/t5/Desktop-Operating-Systems-e-g/HP-PAVILION-A6109N-amp-windows-8-System-w...
Hi,
just recently upgraded to Win Pro on my HP PAVILION A6109N. I also bought a toshiba canvio desk 3TB. What I notice is that if I reboot my pc with the extermnal HDD connected, my system will not boot.
I have check my BIOS boot settings and the order of the boot.
I have tried disabling USB Legacy Support in the BIOS
I have reformatted the external HDD
but still my desktop will not boot if the external HDD is connected....If I disconnect the external HDD...the system will boot up ....
I am at a loss....*** scratching my head ***

Update: The only solution for me was to format the drive as ext3 and plug it into one of my Asus RT-N66U USB ports, as most routers don’t yet recognize 3TB drives as NTFS. It’s not much help to people who don’t have a router with this capability, and it also slows transfer rates to ~12MB/s.
Given the short length of the cable, your only other options are to have the 3TB Canvio sitting right next to you so you can unplug from a front USB port before each boot, or place it towards the rear of your desk and crawl under the desk to disconnect it from your PC prior to each boot.
It's a pity because Toshiba produce great internal HDD's, but my experience when it comes to external drives is they're simply junk. I wish I had read the reviews before purchasing.

Satellite Pro A300 - Cursor constantly moves when external mouse connected

Hi there
I have a Satellite Pro A300. When I attach a mouse directly by USB the cursor is constantly moving. I also have a mouse attached via a Toshiba docking station and that works perfectly.
It doesn't matter which USB port I use or whether the laptop is connected to the docking station or not, or whether it is running on mains or battery power.
I thought it was the mouse that was the problem so I went and bought a new one but the problem is persisting.
Actually, while I have been writing this post, it has stopped doing it and then started again! Very frustrating.
Can anyone help?
Thanks
Susib

Hi
How about the touchpad does the cursor moves and jumps using the touchpad?
Try to disable the touchpad while using the USB mouse check if you can notice a difference
How about BIOS?
Do you have the latest version installed?

MacBook Air is getting hot when external monitor is connected - restart solves the problem

I have a two weeks old Mac Book Air 11" (128GB / 4GB / i5). Sometimes when I connect it to my external monitor, the FAN is getting loud and the MacBook becomes very warm on the surface near the "F3 button". The activity monitor says CPU is at 0-1% and there's no process that causes any CPU load (I switched to "show all processes" of course). Nevertheless something makes the Mac becoming hot. A simple restart while the external monitor is connected solves the issue completely, temperature and fan speed are instantly decreasing. Is this a issue related to the graphics driver? For me it seems the behavior is caused by the graphics processor rather than by the i5 CPU as activity monitor does not show any process causing high CPU load.
Known issue?
Thanks!

I was runnig into the same problem. Plugging in to the apple 23" display at work worked well, but when I plugged in my Dell 23" at home the fan started being noisy...
ALTERNATIVE SOLUTION: it seems to me that putting the air to into SLEEP MODE and back solves it as well!!
I will confirm later on.

IMovie doesn't recognize camera when external hd is connected

I can't import a movie from my camera into iMovie6 when a external hd is connected.That is,a 400gb LaCie tripple interface or a freecom classic sl hard drive400gb.
When a LaCie Mini 80gb is connected there is no problem.
When one of the above is connected with firewire iM doesn't recognize the camera at all.
When connected with usb2 it does see the camera,but only imports for about two seconds and that quits.
Any suggestions?
Jacqo

Thanks Karsten.
Yes, my camera is a Canon,but not one of the models mentioned in that tech note.
I've solved it now.
Reading your reply gave me a bright idea.
If that is true why can I import with the smaller LaCie hd connected?
Look at the type of firewire cable Jacqo.
Yes,that is a different type of cable;connected the 400g with the cable that came with the 80g hd and eureka,it works.
So it was just a matter of the right type of firewire cable.
Why didn't I think of that earlier.
Again ,Thanks Karsten.
Jacqo.

Wifi dropping and slow when external USB hdd connected

Hi,
I have a problem with Wifi connection in my Macbook Air 2014 running Yosemie 10.10.1. I have USB hub, which is plugged to power and I have connected external sound card, Apple keyboard and my external HDD (I used it as Time Machine) to it. Sometimes my Wifi starts dropping and internet is extremely slow, but when i unplugged external HDD, everything seems to be fine. I've tried 3 USB hubs, but still the same problem.
Does anyone have similar problem?
Thanks for any advice.

go into system prefs -> startup disk and select the disk with os x on it. that should solve the problem

Error Message -6753 when External Drive/Printers Connected

I downloaded Airport Utility 5.3.2 (532.8) and am now having problems with my Airport Extreme. I have a green light and internet access, but I am no longer able to access the external drive or the 2 printers connected to the Airport (all connected USB through a hub).
When I open Airport Utility and try to update the settings or check on the status of the drive or printers, I get the -6753 Message that prompts me to check my connections. So far, I have repaired permissions, unplugged and disconnected the Airport and even reset it, but when I hook the drive and printers up, it always reverts to this situation.
Has anyone found a fix for this problem or knows how I could install an earlier version of the utility? Thanks in advance.

You have a hardware fault. Make a "Genius" appointment at an Apple Store for diagnosis. It's a free service.

[Solved] Wierd boot order when external drives are connected

So, I've got two external drives, an ntfs drive and ext4 drive. After a recent upgrade, I get this error message when starting up the computer with them connected.
Bootloader: syslinux.
For the ntfs drive:
::performing fsck on '/dev/sda1'
fsck: fsck.ntfs: not found
fsck: error 2 while executing fsck.ntfs for /dev/sda1
ERROR: fsck failed on '/dev/sda1'
::mounting '/dev/sda1' on real boot
mount: unknown filesytem type 'ntfs'
For the ext4 drive (Megadrive is the name of the hard drive):
::performing fsck on '/dev/sda1'
Megadrive: clean, 230913/188148544 files, 193365856/732566385 blocks
ERROR: Root device mounted successfully, but /sbin/init does not exist. Bailing out, you are your own. Good luck.
With both of them connected, it gives the same message as for when the ext4 external is connected. When they are both disconnected, it finds the proper drive that I recorded in syslinux.cfg file.
What could be causing this? If someone could point me in the direction of how to troubleshoot this, that would be a great help?

Crash when external HD is connected

I have a Western Digital 500 GB MyBook drive with a folder named "iMovie events" where all of my iMovie 08 clips are stored. There is also another folder named "iM HD" that stores three projects from iMovie 06 on this drive as well.
If I eject and disconnect the Western Digital drive, iMovie 08 will start up just fine, no problems. After it is started, if I connect the Western Digital drive, I get the spinning beach ball and a few minutes later iMovie crashes, quits and asks me to send a report to Apple.
If I mount the Western Digital drive first, and then open iMovie 08, the spinning beach ball comes up right away and after a few minutes iMovie will crash, quit and ask me to send a report to Apple.
I've searched the forum for a similar problem to no avail. Any guesses as to my problem?

Just FYI to anyone who stumbles across this thread in the future who might have a similar situation.
First, the FW ports on my Western Digital external drive crapped out and I read about people who had WD drives fail on them rather quickly. So today (black Friday) I picked up another 500 GB drive and transferred all of my video from the WD using the USB port to the new drive.
After transferring all of the video (thankfully without the WD drive dying), I trashed all of the iMovie Event cache folders and opened iMovie. Again it tried to process all the events and quit before finishing. So, I trashed all of the cache folders again and the next time, I moved half of my event folders outside the iMovie Events folder. The next time I opened iMovie, it was able to get all the way through the processing task and I could see all of the iMovie Events that I left in the folder. I closed and quit iMovie and moved all but the last three event folders back into iMovie Events folder. Re-opened iMovie and it found all the new event folders. Repeated the process one final time with the last three folders and everything is opening and loading as normal.
Now, I just need to try to find out why the iMac isn't seeing the WD on the firewire port. Hopefully I can still RMA the drive if the ports somehow were fried.
Anyhow, I hope this might help anyone who may encounter a similar situation in the future.

Flashing Amber when external HD is connected to AirEx Base Station (n)

My new base station (latest model) has been operating perfectly giving good wireless connection to both the internet and my Lacie HD. I don't always power up the Lacie HD, only when I need to access files, most of the time I use the AEBS for just the internet.
Just recently however, whenever I press the blue power button on the lacie to connect wirelessly - my AEBS green light turns to flashing amber.
Can anyone explain why this has just started happening? I usually have no problems with this set-up, and have made no set-up changes.
Thanks

I agree it is not "officially" supported by apple. But with the new firmware, they do claim that it can be used to back up data using Time Machine.
I, too, would like to know where "they" claim that. It's certainly not here: [AirPort Base Station and Time Capsule Firmware Update 7.5.2|http://support.apple.com/kb/DL1106].
Since it has worked for few people, why shouldnt it work with me?
It does work for some of us, for a while. But this forum, and the Time Machine forums, have many threads complaining that it worked for days, weeks, or months, then suddenly the backups were corrupted beyond repair. That's happened to me 4 times in just over a year.
You might try the things in #D2 of [Time Machine - Troubleshooting|http://web.me.com/pondini/Time_Machine/Troubleshooting.html] (or use the link in *User Tips* at the top of the +Time Machine+ forum). Some of those steps may help (but won't prevent the corruption problem).

Fan running when external display is connected

I have a MacBook Air 13in, mid 2011, 4GB memory, 1.7 GHz (iCore 5), running OS X 18.3.
With the laptop on, every time I connect an external display (HP LA2205wg) through a miniDisplay to VGA adapter, the fan starts running wild and it is so loud to disturb my work. Yet, I check the activity monitor (All processes) and there does not seem to be any process taking a lot of CPU.
However, if I swich the MBA off, wait a few seconds for the fan to stop, and then restart the MBA, there is no fan noise. I have to do this every day I get to the office and connect the external display. It's annoying, as I have to reopen the same files etc.
I have browsed the apple support forums and I have seen similar posts, some dated 2009. Yet no actual fix is suggested in the posts. I am still giving it a shot, hoping I don't need to waste even more time to go to an Apple store. Any help would be greatly appreciated.

I was experiencing this 100% of the time at work with projectors. I found that once I forced the GPU to NVIDIA in the BIOS... the issue was resolved.
I'd rather have stability than battery life.

Can't connect to my wifi network when external monitor is connected

The computer is a very new Retina Macbook Pro. The monitor is an older Alienware/Benq 20" (3:4) LCD. I'm using a DVI to mini-displayport adaptor and plugging into the thunderbolt ports on the Macbook Pro. Router is a Belkin F5D8233 Wireless N router. As soon as I connect the monitor my connection to my wifi network times out and refuses to let me connect (every attempt just results in a "connection timed out" error). However, I was surprised to find that I could connect to my neighbor's network without any issue. Anybody have any idea what the issue could be?
