Re: Compaq Presario CQ62 410c US power supply Question

Hi all ! I am having some problems with the same laptop. I have connected the center pin directly to the 19 volts supply and now the laptop is dead. Later I foud out that the center pin is actually connected to the +19v rail throght a 390k resistor. I hope this helps.

B700029 can you tell me any advice on the motherboard. Should I replace the KB chip? or where should I look for signs of trouble?
