Question Toshiba Satellite Pro C50 - will not boot/run on battery

Aug 5, 2020
Good day all

My Toshiba Satellite Pro C50 has just developed the following problem.

It will not run or boot on the battery.

When the AC cord is connected, the battery is showing as 100% charged but as soon as the AC cord is unplugged the laptop immediately dies and does not respond to the "on" button. I have also tried another battery from another machine that I know is working.

I have tried removing and reinstalling both the battery and the cmos battery. Just fyi, the laptop does not seem to have a hard reset button.

Any thoughts?

Kind regards
