1.	Solve : Laptop motherboard repair?
Answer» Hi, I plugged my LAPTOP to the wrong voltage 21 V instead of 17 V and I fried something because of the smell. I plugged the adapter later & the lights flashed & there was no power on the laptop, I already replaced the motherboard but I get the FLASHING lihgts & no power too. What else can I do?You replaced the MBoard and it still doesn't work ? ? Is this a used MBoard ?No, it's a new oneThis may seem cynical. Sorry. But in hind sight would have been BETTER to let someone else repair the laptop. Still, you might sell the laptop for parts and go buy a used laptop of the same type. Do I need to secure the motherboard with all the screws back so it's grounded before I TURN on the laptop?Did you try this without the battery connected. Just in case 21V tombstoned your battery.
