Guest sparks691@centurytel.net Posted July 21, 2007 Posted July 21, 2007 I have an older laptop (about 3 years old) running Windows XP. I can't get automatic power management to work. Using the Power Settings in window in XP, I set times for Standby and Hibernate on battery power. XP just ignores these settings and runs the battery down to nothing. I can choose Hibernate or Standy from the shutdown menu (or sleep button) and it works just fine. The display turns off at the time I specify and stays off until I touch the mouse or keyboard. I am assuming that if the "manual" Standby and Hibernate works then the BIOS setings must be correct. I looked at the BIOS APM settings and it was not clear at all which settings to enable/disable.

Definitly an XP issue. Next step is to disable everything in MSCONFIG startup and try again.
Guest sparks691@centurytel.net Posted July 22, 2007 Posted July 22, 2007 Re: Laptop Standby and Hibernate problems Ok, even more confused but closer to solution. Booting with all startup items disabled had no effect. If I select one of the default options in the power management window (Max Battery or Portable/Laptop, for example) everything works. I will test variations of these default settings to see when it "breaks". I suspect it may have something to do with saving the power profile. It looks like changing the settings has no effect (even if you click "Apply") unless you "save" or "save as". BDS
Guest sparks691@centurytel.net Posted July 22, 2007 Posted July 22, 2007 Re: Laptop Standby and Hibernate problems Now, I modified and saved a new power profile and it doesn't work. Apparently any deviations from the default profiles are not tolerated by XP. If I change the standby time from 5 min. to 15 for example, standby will not happen unless a battery alarm action is set to standby. BTW, I checked another laptop and got the same result. Am I the only one or is this just another windows bug that eveybody lives with? BDS

If you have a laptop with its own Power Management setting, you might want to check there. Patty
