Hi I been given a laptop to fix. its a Toshiba C855
When you put it on charge the Laptop says its charging OK (the batter has the Plug thru it) but the percentage battery charge goes down not up. I have tested the volts from the charger and its giving out 19v so not under feeding. My Guess is that the battery on its way out but don't want to fork out on a new one on a whim.
