Battery life and windows power manager

by bli47 Jul 13, 2007 7:35PM PDT

Last week a friend got himself a new laptop and since he and I have the same machine he donated the old one to me so I could use for instance his battery. It only had a life of 20-30 mins from fully charged to windows shutting my machine down at 3% power left.
After this I changed back to my own battery to find it now also had a very short life. While it still used to do about an hour, it now died at 30 min.
This morning I did a little test. I told power management to do nothing when the battery was to die and looked what happened. After about 20 mins the warning message showed up. I ignored it and saw battery charge go down to 0%. I closed all applications but my browser (on wireless!) and went on. The battery finally died after roughly one hour and 15 mins!
In the old windows 95 one could recalibrate the power meter. In XP I have not been able to find that feature.
Does anybody have an idea how to correct this power management issue?

In Win XP go to desktop > right click anywhere but over a icon> .display propierties> screen saver tab> look for Power button > go from there

Calibrration is not a Microsoft feature.

So there is no generic method unless you get lucky and it's in the control panel.

If only you had shared the make, model number of that laptop then I might have known where it is or would be able to seek out if it was documented.
