Dell Precision M4400 - no hibernate option
Hi,
I have just rolled out a Dell Precision M4400 with Windows XP Professional 64 bit installed.
Does anyone know where the option is to enable Hibernate? The hibernate tab in Power Options is missing, and I have been unable to find anything in the BIOS.
Many thanks.

Open command prompt & type "powercfg /a". It will tell you what settings are avaliable (such as standby and/or hibernate). If it tells you that you have a PAE mode, you have 4 gigs of memory and hibernation has been disabled.
From a command prompt, enter "powercfg /hibernate on" to enable hibernation (or it may give you an error if something else is wrong.) If you get an error, check your Divice Manager. If you have any yellow exclamation marks (device not working properly) hibernation probably won't work.
It's possible that a bad device driver is the cause, or a bad program (McAfee 3.1.4 was known to kill hibernation).
Also, hibernate is incompatible with Terminal Services. If enabled, disable the TermService service, reboot, and the missing Hibernate tab should be restored.
Read "How to troubleshoot hibernation and standby issues in Windows XP" at Microsoft Support. http://support.microsoft.com/?kbid=907477
Lastly, not all laptops support hibernation.

One other thing. All your driver MUST support standby / hibernation.
Make certain all your drivers are up-to-date and your not using any generic drivers (esp. video and chipset drivers).
