i broke my AC adopter and used a similar one with 19.5 V and lower Amp than what was on the original adopter. unfortunately it had reverse polarity and as i plugged it in, my laptop died immediately.
there was no smell or any thing but it wont turn on anymore. i have replaced the battery and also got a new AC adopter but nothing works. it's completely dead
will replacing the power supply fix the issue or is the motherboard fried?
i'v searched the internet for a solution, some say just replace the power supply some suggest motherboard components need to be replaced. i'm not sure what to do.
thank you for your assistance.
Without a doubt a component or components on the motherboard have been damaged. Possibly a diode or fuse (they look like solid state components). The following links will explain more.
