hello,
I have this imac come in for repair i get S5 and G3_hot power.when i press power button the S5 light goes off and then come back on but the machine does not turn on.I reprogrammed the bios cleaned the Me engine same problem.I notice that each time i remove the cmos battery the machine comes on and works fine .But every time i have to remove cmos battery for it to turn on.what is this problem with cmos battery to reset.
I have a same problem with Hp probook.
anyone can tell me where i should look in
thanks

Okay so 2 things I noticed that the voltage to intruder_L signal and 32k osc was not correct waveform the pch needed a proper reflow and now the machine works perfectly no problem the pch is SR176
Thanks
