If the laptop works using the AC adapter & works using a charged battery, then the CPU is not the problem. So the problem has to be the battery charger, either it is faulty or there is a broken wire or connection.
Randomly removing items & replacing them could easily end up causing the laptop to stop working.
At present you can use the laptop with a fully charged battery or using the AC adapter, so at least you can use it.
Buying 2nd hand items is always risky as often the reason they are sold by someone is because there is a problem with it.
agree with you.
if i could only find a diagram for this board and to see where the charger part is located....

its just i have been very lucky buying second hand... 28bucks for a used board, 43 for a new one... i got the lesson....

now i have two board completely functional... but they cant charge... (they would work great as a desktop computer lol
