I am running Windows XP Pro, will all the service packs and driver updates currently available. Whenever I bring my 4760 out of suspend mode, I have no keyboard! That is, no matter what keys I press, nothing happens (even ALT-CTRL-DEL)

Everything else works ... mouse, Internet, etc. ... but the only way I have found to get the use of my keyboard back is to reboot. Anyone have any ideas on what could be causing this or how to fix it???

Sorry to reply to myself, but I realized after more testing that it doesn't occur everytime. Sometimes it comes out of suspend just fine

This also occurs sometimes after hibernating, but again, annoyingly enough, not everytime.

If anyone has any thoughts, I would appreciate it.

There don't appear to be any BIOS updates available for the 4760 on sagernotebook.com -- did you find a BIOS update elsewhere?

it might have been 88 or 56 that i saw it for. i guess it's a call-tech-support thing if you don't hear from Adam here.

suspend issues

Hi:

Give the following two ideas a try and see if it helps:

1. Stop usiing windows hibernate. If the computer has a battery management program, try using that excusively. If you have both windows power management AND another power management program that may be causing the conflict.

2. Reinstall your OS. The OS and any system drivers you loaded could be causing a conflict.

Hope this helps

1) I already disabled hibernation, but found that the problem occurs with suspend as well as hibernation. Not everytime, mind you, just sometimes. Especially seems to happen when I am in a hurry.

2) Reinstall the OS? Well, I could wipe the drive and re-install the OS, then install each driver and application again, testing suspend extensively after each driver installation, hoping to determine which driver is causing the problem, but, umm...not to sound ungrateful for the advice...but that would be insane! That would take many, many hours and may not even isolate the problem.

In absence of other ideas, I am just going to continue to live with it, as annoying as it is. When it happens (which seems to be about 50% of the time I suspend), I can either reboot or suspend/unsuspend again to get my keyboard back. Really annoying, but survivable.

I too have the same issue when I return from Standby, no keyboard.

I also have an additional symp[tom that when I return from Hibernation, I have no screen. It appears as if the keybaoard may work, but no video. If I reboot, all is fine.

Any ideas?

I have found that if I simply put the machine back into SUSPEND, then bring it back again, I get the keyboard back more then 50% of the time. Still annoying, but faster than rebooting.

Microsoft recently released a rather cyptic recommended update to the USB subsystem in Windows XP, which is related to Suspend and Hibernation. Since installing that, I have not experienced the loss-of-keyboard after suspend problem (yet). I am hopeful that this actually resolved the problem:
