Most likely I won't reball the CPU, just reflow it.
What is interesting, that initially when I got the board from Ebay, it was working great, I have installed Windows, and it worked.
After a while,...

Can't be solder balls cracking?

Re: Asus Q502L does not boot up properly

There is only the ITE IC and the CPU on this board. What could cause this issue?
BGA solder issue at the CPU?

Re: Asus Q502L does not boot up properly

Re: Asus Q502L does not boot up properly

It's been a while since I have looked at this laptop, but I have just had a bulb turn on above my head.
The laptop hard drive, has to have a 12V supply as well, other than 3.3V and 5V supply?

Re: Asus Q502L does not boot up properly

I have even replaced the hdd daughter board, so it is hard to believe that the connector is causing these issues.
I will check the connector, just in case.
It recognizes a USB stick. Starts...

Re: Samsung UN40C6300 clicking fast

I don't know, if I should mess with a board that most likely I will return.

Unfortunately, there are no schematics for this board.
I will look at it and, if I can't find it, I will make some pictures.
