Electronics 2000

Hi,

New to this forum so hi all.

Basically our family laptop (Asus x51rl) died a death due to a faulty power supply. I could smell burnt silicon from inside it and dismantled it to find the issue.

I've found the source of the issue which is a burnt component by the battery socket which must be some sort of shorting pin. I've fixed computers all my working life and build electronics for a hobby but have never had a go at fixing integrated circuits before. Hell, what have I got to lose

Can anyone identify the component that is burnt out, I've attached two images of the damaged board and a couple of images I found on the net of the same board area with no damage.
Thanks for any advice,

Gary

Hi,

Found some more information. After a lot of searching (mainly non-english sites with google translate) I have found a few more images:





According to the forums it is a 5 volt Regulator part of the 5 volt stabilizer circuit labelled PU5900. The actual chip has marking 8C752 and they call the chip Stabilizator (but this could be a bad translation). They also mentioned replacing it with L78L05ACUTR.

Does this seem right from the new images? Would replacing the chip with the L78L05ACUTR be ok?

Thanks again,

Gary

You now have to ask the question

did it die or was it killed?
