i open my macbook pro mid 2010, trying to replace the battery, and i’m using a iron screwdriver. i touch one component by mistake with iron screwdriver and its cause an electric shock. i was surprised because i had already removed the power and the battery but it still cause an electric shock. when i done replacing the battery, i see my macbook run much slower, didn’t detect the battery, the fan run faster and the macbook run with much stuck / lag. what i have to do ?
Capacitors work like miniaturized power banks and can store power for some time even after power supply has been removed. It’s very likely the short circuiting damaged some component on the logic board. If you have the skills and tools you should find and replace whatever is damaged or pay someone into component level repairs to do the job for you. A further possibility would be a logic board replacement.
