Dell Dimensions 5100 Power Button

I have a Dell dimensions 5100.

The power button 'Flickers' orange, it is not a standard flash but flickers as though there is a faulty connection.

Any ideas what it could be.

This happened a cuople of days ago and after a bit is testing (removing /reseating/cleaning) I played about with the button and it started up agaian, although it then blue screened and I had to run a chkdsk on the drive to repair it.

It has now happened again.

I am assuming based on the fact I had it working again that it is not a power supply issue - could it be a faulty power button?

Re: Dell Dimensions 5100 Power Button

The power light is tied to the Mother Board and therefore it could be an issue with just about anything on the PC. Here is the trouble shooting documentation and the link should bring you directly to what the various conditions of the power LED mean.

There is also a detailed listing for the HD light as well as some diagnostic lights (if your paticular variation is equiped)

Dimensions 9100 added RAM now won't boot remove batery and will boot or reboot not from power off

Possibly a bad power supply. If you remove all the memory and it still won't power up unless you remove and re-insert CMOS battery that is a symptom of a defective power supply

Main power button LED is flashing or solid yellow

This is a major problem that crippled Dell. Moels Optiplex Gx260, Gx 280, and Dimensions of whose mdel number i don't remember have this problems. This signal shows that either a power supply or your motherboard is malfunctioning. If you have an insurance better use it now or else get some technical assistance.

Dell Dimension 5150 automatically turns off

That flashing amber light is usually a sign the power supply is failed or is failing. I would suspect the power supply is the problem in yours. It is the better of the two problems connected with the flashing amber light..the other is motherboard is failing. Arrrr!
hope this helps (it takes a standard- oh say 350 watt 20-24 pin power supply unit.)
Hope an answer helps.
Please leave rating, thankyou
