Call to Acer Aspire 5670-series owners! Help!

post #1 of 3
Thread Starter 
So, long story short I have a very sick Acer Aspire 5672 in my possession. Attached is an image of what is wrong. What I would like is for someone to tell me what ICs I need to pick up to replace the asploded ones.

If someone could crack theirs own, and obtain the identification information on the tops of these that would be amazing! Obviously, I can't because two (Blue and White) and of the tops are irreparably damaged, and the third (Red) is mildly obscured making the identification information ambiguous. I could probably work on the red one for longer and get it, so the real priorities are the blue and white ones.

Note on picture: It is from pre-exploding, but I assure you, they have definitely seen better days.

This is very much appreciated!

Ok, so I was able to read them after donning a pair of extremely high strength glasses and grabbing my flashlight. They are:

Red: 4704 (BD553B)
Blue: 4422 (???)
White: 4422 (???)

The value in brackets is, I assume, a serial number of some sort. I presume the four-digit value is a part-number of some sort. They are all produced by the same company. Only the company logo is printed on the chips, and it looks familiar but I can't put a name to it. It doesn't appear on any larger chips (Unlike Infineon which appears several times with its full name printed on the chip). The logo looks like this:

Don't know much about electronic circuit, but have you tried just to visit an electronic stores and show them the board? My guess is that these IC are pretty standard for use on other circuit boards as well.

cheers ...
