Standby/Hibernate disappear on laptop Windows XP Pro

[michel young]

Recently I noticed that on my laptop the Suspend/Hibernate option has
disappeared. I checked the control panel and the tick box to enable
the feature is gone.

Here's what I've tried so far:

Under Computer Management -> Computer -> Advanced Configuratoin and
Power Interface (ACPI) PC: I've removed the feature restarted the
computer...nothing's changed. (The item reinstalled itself.)

Tried to execute the: %windir%\System32\rundll32.exe
powrprof.dll,SetSuspendState command from the Start -> Run box.
Nothing happens.

I restarted my computer and at the login page I noticed under options
the standby feature is enabled. When I log in, no more standby. If I
logout of the computer back to the main login screen, no standby. I
have to restart the entire computer to get the standby item to appear
in the login screen.

So some strange setting is disabling the standby feature of the
laptop. This is really annoying considering now I can't just put the
laptop to sleep now, I need to restart entirely.

Any ideas on how to find the process or application that's blocking
the Standby feature?


Thanks for the help,


Michel

What you DON'T want to do is mess with the ACPI HAL setting again.
You're just lucky you didn't trash your laptop's ability to boot.
That said.....

What's probably happened is you recently either installed a driver or
software that is not XP ACPI compatible and the system turned off the
Standby - Suspend - Hibernate feature. Now you need to find out which
driver, what software, what hardware, etc. is the cause.

First thing to do is open the hardware tree in Device Manager and see
if everything is OK. Trouble shoot from there. But definitely do
not try to remove or otherwise change the ACPI HAL.
