Hi there, my tm 8204's battery is now about 3 years old, and can only hold the power for about 30 min.
So I got a new battery for the laptop, not an original battery but new,
and after 1 charging of the battery, there was no power for the laptop.
I thougt that an original battery could do better, so I switch it for the not original battery.
Guess what, the same shit happens, after 1 charging,
there was no power in the battery, only if I got the electrical wire...
