I have the same problem. Amber blinking light. green light on the motherboard stays lit when it's plugged in.



I've talked with Dell tech support. One guy suggested replacing the motherboard, front IO panel and the power supply. Unfortunately my warrenty just expired, of course, and they won't extend it as my computer is having problems. Plus extending is cost about 300 dollars for one year. So another guy in the spare parts department said 95 percent of the time the blinking light means power supply and so I ordered that. I hope it fixes the problem. I have the same problem.

I ordered a new power supply from spare parts at Dell. I installed it and it actually worked! I am happily surprised at my good fortune of finding a solution. Good luck to all in fixing it.

Ok, so pretty much when i turn on the button, there would be an amber color blinking, this has been going on for the past 3-5 weeks, the green light in the back is always on, but won't turn on.

Computer often won't boot up when I try to switch it on. An expert said that I should just leave the computer switched on all the time and that it was the mother board. Otherwise when it is on the computer works fine. Is there any other solution to the problem? Computer often won't boot up when I try to switch it on.
