Here are pictures of the possible problem I bought the whole computer from an auction as broken or for parts. Everything else works fine, except this As you can see, someone did a poor solder job on the EFI chip (or is it?) and I wonder if it could be the cause for the computer not to power up at all. Even the fan doesn’t go on. Nothing. It’s dead as a door nail So how would I proceed? I guess analysing the board with a multimeter could show what’s wrong with it, but I don’t have a clue how would I do that + I don’t have much skill doing repairs at a component level. Thanks for any help!
Marhowl , it is absolutely possible. Yes, it looks like a repair including some bridging of the traces, really not a bad solder job:-). Since you do not know anything about the history of this IC you would not know if it even has the firmware programed before it was installed.
