I changed the battery of my Macbook Pro mid 2010 and it worked all fine for some time.
Then I stopped using the computer for a while (around 1 year or a year and a half) and now the computer won't switch on unless I open it and I remove the battery.
I've done that, removed the battery, switch it on and reset the SMC and the NVRAM or PRAM. Then plugged the battery on again and nothing. Not switching on again.
I also tried leaving the computer charging the battery for about 5 hours. Nothing.
If the battery is wrong, why won't it switch on when still plugged into the network via magsafe?
I would rather not buy another battery because they are about $50 and this computer is 11 years old. Trying to look for another solution if possible as I won't be using this computer that much anyways.
