Re: dead asus x550d

I don't have a schematic for this model, usually its hard to find schematic of asus. that's why I give you image's link as reference. However, you could search the boardview.

- Did You Check Resistance at 2 coil near capacitor 220uF 6.3v on bottom board? Of course without adapter and battery


2 pieces Caps with value 220uF both of them have 6.3v that indicate those caps connect with output the IC, you'll had seen this on many board of notebook especially near DC/DC controller for 3.3v and 5v or right on the other side of the board (whether on top or bottom)

Re: dead asus x550d

the two coils are not shorted to ground so I think the two capacitors are also good,

Re: dead asus x550d

i reheat the ic and i got 5valws but no 3valw and no light indicator

Re: dead asus x550d

is it possible that my 3valw/5valw ic has a problem?
