Touchpad disabled after sleep

2009-04-13, 3:10 AM

I have a u330 running Windows Vista with the Synaptics pointer driver installed.  When the machine sleeps for more than 30 minutes and is revived the touchpad is disabled and pressing Fn-F8 has no effect (it remains disabled instead of toggling).  I called support this evening and we fixed it by resetting the BIOS settings to their default values, but that doesn't seem like a tenable solution.  Anyone else seen these issues with the touchpad?  I reflashed the BIOS this morning with the latest from the Lenovo download page, but that's because I was already having (different) touchpad issues.  I tried searching threads with no success, but if you happen to know of an existing discussion on this topic, a link would be great.

This could be related with bad driver and usb polling interval.

First is resolved by getting latest driver from synaptics com and second can be fixed by these two registry tweaks.

I installed the registry tweaks but still no joy.  The minute I open the lid to bring it out of sleep and press a key to activate the screen, the "touchpad disabled" light comes on and will not toggle with Fn-F8.  At times I've even had the keyboard go dead on me, which I fix with a draconian reboot.

Well, I'm not 100% sure yet, but I booted into OKR, it performed a scan of system files and noticed some things were amiss, I OKed a fix and the touchpad seems to work now coming out of sleep.
