Windows XP(Home) "Sleep" & "WakeUp" Keys & HIBERNATE.

[Guest]

I used to be able to use the above 2 keys on my keyboard until recently and
also HIBERNATE is not shown under Control Panel's "Power Options". I have
tried Diagnostic Boot, Selective Boot and Safe Mode but Hibernate does not
return. I also followed a link which suggested typing "sigverif" into "RUN"
from START & searched WINDOWS, WINDOWS\system32 and WINDOWS\system32\drivers
but this did NOT reveal the suggested culprit ( a WinRT.sys driver- in that
case.). So I cannot find out why I cannot use the 2 Keyboard keys OR
Hibernate facility. Can anyone suggest any other avenue I could try, please?

If the problem is recent you might find that System Restore will do the
trick. Go to Start->Help and Support->Pick a task->click on System Restore
link and follow the onscreen wizard to restore your computer to an earlier
time. Only go back to the day prior to the problem occurring and only use
this option if the problem is very recent like within the past few days.
System Restore won't affect things like data files you've created or e-mail
and other non system files and it doesn't affect anything in the My
Documents folder but it will revert backwards so any system changes you made
after the restore time will have to be redone including any software you may
have installed after that restore date. System Restore in undo-able.

For hibernate to function, ACPI must be enabled. Check System Devices in
Device Manager to ensure that ACPI is installed and functional. ACPI must be
enabled in BIOS settings (usually under Power or Power Management) and
functioning when XP is installed. A repair install or full re-installation
is required to configure ACPI. Also check your Windows folder for a file
named nohiber.txt. This file will contain information why Windows won't
operate Hibernate. In most cases, a suggestion will be offered as to how to
proceed and be able to use hibernate.

I'm not certain about your specific keyboard but some devices require
software for special functions to work. Perhaps you need to reinstall the
sftware that came with your keyboard.

Hello,

there is a "good" KB on this:

support.microsoft.com/kb/266169

It is for Win 2000 but also applies for Win XP
