T520 battery7 issues

2019-11-26, 14:59 PM

Hi guys, i have an issue with my battery on an old t520, it's currently using a 9cell battery, but i have also tried 6 cell.

the GPU is off, and no unessercy processes are running in the background.


what i have done so far

-Changed the battery

-Ran a battery reset

-tried turning optimus off

-reinstalled with windows 7 instead of win10.

-running firefox as browser (less CPU heavy)

-disabled almost every startups

-Running avast AV for security with less powerusage.


However no matter what i do i never get above around 2:30 on battery. this is with the old 9cell 66.2 wh remaining.


processor: Intel: I7-2720QM 2,20ghz.

Ram:  8gb


Please help, as in this current setup i wont be able to use on the train to school even :(
