Lenovo T520 Battery drain

2019-10-31, 10:01 AM

Hi, i have just purchased an old T520, but are experiencing issues with low battery.

it's a T520 I7, 8gb ram with a 500 SSD

 

I did install win10 on it, but as the battery where about 2 hours with a 9-cell battery i tried replacing the battery, but are still only getting about 2 hours 40min on a full charge.

reinstalled win7 ultimate64bit incase there where issues with optimising it in win10.

still no change.

i have ran the driver updates with service bridge, driver booser as well as windows update as well as the battery firmware update, but still no change.

i am currently running full battery7 saving, and it says the usage is about 20-24W, just running Chrome pretty much

Does anyone have any solutions on how to fix this?

 

/Andreas
