Hi all,

After a faulty power supply, a friend bought a generic one that never managed to power up the laptop. It ended up draining the battery and then we couldn't power it.

We would a tleast like to get back the data on the ssd, sadly bitlocked and with no recovery key at hand...

I don't know if we can manage to identify the faulty capacitors and replace them (not even sure I'd ba able to do it. I did some soldering but never on such tiny things).

 

An alternative might be to bypass them entirely... Not sure if that is reasonable, but since most of them are there to eliminate noise and that I just want to power it at least once to get the recovery and/or the data...

 

Thanks a lot !

After opening it up, I noticed the following :

 

I found a schematic for what I think to be a similar board : https://www.rom.by/files/1bc0e_asus_ux31a2.pdf

Page 88

I fixed the URL from my previous posts.

I thought the black ones were also capacitors but it turned out they are resistors (:

 

The second resistor (orange crossed) is now gone. It was completely lose...

It also seems there is a short.

Testing both in 1 and 2 got me a short.
