The green light means that the 5 volt control circuit is on. This is what allows the power on switch to begin the sequencing of the power supply. I'd have to ask what P1 looks like. If it's a square 4 pin connector it could be for the CPU but would provide 12v and shouldn't even be a factor at that point. This could still be simply a power supply. What happens if you press the power button with P1 disconnected? If the PS is good, fans and drives should start but if the connector is for the CPU it's not going to start. If no fans, beeps or drive activity, I'm suggesting power supply first.
Hey everyone. Im new here and i have a problem thats really getting me angry. Here's what I have:
HP Pavilion a1630n
AMD Athlon 64 x2 Dual-Core 4600+
XP Media Center 2005
I recently shut down my computer and tried to turn it on the next morning and now it doesnt turn on at all. No beeps, no fans/lights, no activity whatsoever. When everything from the PSU is connected inside the computer, the green light on the back doesnt glow at all. But when I take out the P1 connector from the motherboard, the green light turns on. Any ideas on whats going on?
