Man, that did not take long :lol:
My A600 needs repairing. It's just as dead as a doornail. There's no obvious motherboard malaise, you switch on the power, nada. Not even the LED lights up.
That's one of the best sorts of problem to fix... it might seem terrible but it's not, it probably just means the +5V line is kaput, you need to check the capacitors and all that but it's probably just a resistor that's gone (or even a fuse if there is one). Chances are that as soon as you get a good 5V line the whole machine will be just fine.
Given the choice between repairing a machine with nothing happening and a machine which works 90% of the time but occasionally goes wrong, I know which I'd rather have, any day!
