Hi, i have the C700 which wont turn on and no lights, screen ect- totally dead- PS is good. Switch is good and 3v there shorting when pressed. When plugged in the blue light at the power socket flashes blue for a sec only . PS socket resistance is 8000 ohms Pulled it all apart and 19v is through the input mosfets and sense resistor. 3V isnt at bios chip next to super IO if it is the bios chip? no volts on any leg. pulled all parts off board to see if they are causing short or drag down Tried my PS and NO amps are being drawn and with power switch pushed on too. Fan dosent twitch. CPU ect are cold as no amps drawn Tried resistance to ground of many parts and cant find any shorts and PS wasnt drawing amps anyway. So slightly ON but not fully?. Super IO fault? Also screen disconnected in case that was faulty and 19V is at connector to screen
No lights on front and battery is not being charged.- Checked carefully board and noting burnt or out of place
Any one can help, i have schematic.- where i should look for trouble or is it one of the main chips likely and have to do a full reball ect.
thanks
