win 7 hibernates immediately when plugging off

Hello,

I just uploaded Win7 and I have a big problem.

It IMMEDIATELY hibernates the Laptop when pulling out the cord to run on battery.

I changed the advance battery settings that the Low level is at 10 and the Critical is at 5% instead the original 99-98% settings

If I turn back the Laptop again I'm able to run it for another 30-40 min, I didn't had the time to check it. (My battery is old, but with XP I was able to run for 40 min.)

And my power meter always shows 100% even if it shows 1h:37m or 37m to drain.

Any thoughts, ideas, suggestions well appreciated.

Thanks

Did Bios update, same thing, reset same thing, no luck. But thanks for the effort!
BUT Found the solution!>
In the local group policy editor>
Start>type gpedit.msc in the search box and select the group policy editor program.

Expand Computer Configuration>select Administrative Templates>All settings>

There is the Policy > Critical battery notification Action.

I set it to Take No Action.

So when I plug out the cord it stays on. I'm happy.

Then the problem!

Win7 Battery Meter thinks that my Battery is depleted, is in critical state, says 0min left (100% charged) although I know for sure that is still can do 30-40 min. So its completely inaccurate.

Any thoughts on this now? What's next?

Thanks guys!

Hi,

I have a dell d630 with nvida m135 and a T7500 cpu. Installed W7 ultimate x86 and everything looks fine, but
whenever I use the restart funktion windows logs off, then shuts down rather harsh. All other
power funktions seem fine, hibernate and standby all work. Anyone saw this problem?
