Alarm beeps and orange light flashes when power is switched on.


If you unplug the power cord from the wall and the PSU, then flick the little red voltage switch on the back up and then back down again, plug it back in and it should work again

Dell PowerEdge 2300 Server won't boot


To power off using the power button, press and hold in for more than four seconds.

However this is not solving your problem of not booting, needs some more information. Such as Beeping noises, number and length of beeps. Or any LED.s flashing?

This depends, if it's a disk failure you probably have lost data. If the disk still works the data can be recovered by attaching the disk to a another computer

Same **** happened with my PS3. So I returned it, and got the newer version of it. I went home and plugged it in: The fan came on along with a green light. BUT THEN..... 5 seconds into it, the damn thing shuts down and flashes red along with the three beeps. Not to mention the yellowish orange light. Even the brand new version did the same ****. I am in your same position and I would love to hear a way to fix this. Pretty weak.
