Question

Asus X550 laptop wont start

by Jul 23, 2018 3:44AM PDT

Hello,

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?

I think it's dead. Time to check out how much a new motherboard is.

Thanks for your answer. You don't think it's a fuse or a component that failed?

I have yet to find fuses in laptops. Mostly in the charger. So yes, components can fail but since the makers do not publish schematics (Apple being a little different about schematics) there is no reason you can expect board repair. Especially when the story was told above.
