Also, I have seen that flipping the power sw do the trick, but I would pull the battery and use the jumper to clear the CMOS, in this case.
read this and get back to us: http://www.computerhope.com/issues/ch000312.htm Do you have a little red switch on the back of your PSU? If so, how is it set? to what value?
Sounds like the wire(s) to the power switch maybe broken. Remove the power switch wires from the header, and momentarily short them out using a jumper to simulate the power switch and see if it comes on. If you don't feel confident doing that, then just plug the reset button onto the location for your power switch and try it that way. Using the reset button on the case as the power switch. If it powers up then, the switch/wires are damaged somewhere, you will need a DVM to check which is at fault.................
cpu fan is attactched to the motherboard. I tried switching the power sw with the reset sw still nothing. Havn't tried taking the battery out yet will do that later. I read that document and I'll try the computer with my old psu. The little red tag behind my psu is set to 115v
ok I took the battery out and put it back in. Still nothing. little green light bright as ever but still wouldn't turn on.
I am the friend, and I'm absolutely sure the front panel pins are correct. Also, try as I might, I could find no PC Speaker plug. Once, when we tried to turn it on, I may have heard a faint beep sequence, but it was probably my imagination, or the PC Speaker was VERY quiet. Also, we couldn't get it to repeat (the beeping).
Okay, getting back to the post about removing the battery and it not working, that is not all you have to do sometimes. You have to short out the CMOS, using the jumper, or in the case of one of my motherboards, touching the blade of a screwdriver across two pips. Most have jumpers though, so pull the battery out, find the jumper to short the CMOS, leave it on the clear setting for about 10 seconds, put it back in the normal position, put the battery in, hit the power, and pray like hell you hear a beep or see something on the monitor.
the intel board might be different as i have one here that you have to move a jumper from 1 position to another just to get into the bios setup
I think I found out what's wrong. when I first put the mobo in the new case I forgot to put in spacers. SO i think the mobo fried itself when it shortcircuted it with the case. Anyone agree? And if that's the case are the stuff connected to the mobo also fried?
the faint beeps you though you heard I heard too. It beeped when I pushed the motherboard back alot when I plugged the psu into the mobo.
sounds bad then, are u sure the metal of the case was touching the board? if you have done this then it could have damaged any number of components depending on where the short was.
yeah thats kinda bad. Tried using the mobo outside the case nothing. Hopefully i didn't burn anything else besides the mobo..orelse it'll get kinda expensive to replace.
I just went thru this last weekend-5-12-08. I disconnected all my optical drives and backup hdds and all periperals. No luck, would not turn on with on button. Green light on motherboard also. I figured it was major so I brought the Dell into a shop I was referred to. Took em a couple of days to get to it. Called and all it was was the ethernet card was shorted out. Tech said that was preventing the power up. $56 with labor and new ethernet card and pc back to normal. I found an honest tech. Nerd Works in Baton Rouge, La. He said lightning probably got it. Cox cable so reliable. Cable was not on surge protector. APC doesn't have that connection. Could have been ddp!!
not me!!! apc has coax connections on 1 of their surge protected power bars as a custumer bought 1 today as we were picking up her new computer.
@ddp I just got new pc today. You know anything about LightFX led light software came with a Dell XPS630?
