I think it's dead. Time to check out how much a new motherboard is.
I have a problem with my Asus X550 laptop which wont start and shows now lights. It started a week ago when i repaired my DC adaptor (the socket pins broke off). I accidently connected the AC wires to the DC side and vice versa. After that my Asus did still work but the battery didn't charge, so i ordered a new battery, assuming it shorted. After that it dit work but still the Asus accu didn't charge. After some testing on the motherboard and putting it back together, now it doesn't do annything. It won't start or doesn't show any lights https://www.mupload.nl/img/77eij7vw1e.jpg
. However, there is 19,5 volts on the connection pins of the DC adapter to the motherboard. https://www.mupload.nl/img/nzn4lavin3qrk.jpg
I looked at the motherboard again and think i found a component that is missing. Can someone help me with this?
