Hello,

I've two Acer V5-122P with same problem: short and doesn't turn on.

In primary 19v i found PU4201 (TPCC8131), change and same result and now it burns!

I see PC4416 bruned too, and the line with PC4404, PC4403 shorted...change BQ727, same result.

What can i do?

Sorry for my bad english.

Thanks

If you do not understand this, you should not even try to repair the laptop.

No i don't but i cannot learn?

Do you have right, we must have to learn.
I've to inject 3v on the circuit to found the shorted capacitor.

Thanks for your suport. Topic closed.
