In Reply to: XPS 420 will not boot, fans on high by was6477

Starting to track this down. I have pulled everything off the motherboard. With just the motherboard with power, CPU. All cards are out, all RAM is out, hard drive disconnected, front panel has power.

1) I am getting a blue power button on the front of the case, indicator light 1 only, the miniview on the case is displaying "No memory modules detected".

2) Added 1 gig of new Dell memory, not the same memory that came with the computer. Getting indicator lights 1, 2, and 3. Power button onfront of case is still blue. Miniview display shows "Card case fan failure"; "CPU fan Failure", "System Battery Voltage is low", and "No Display device found".

3) Connected what I now know are the CPU/Card case fans. Indicator lights 1, 2, and 3 are on, blue power button. Miniview displays "System battery voltage is low" and "No display device found". After the messages and indicator lights came up I heard two quick beeps. I also plugged this directly into a wall outlet and got the same results. The hard drive, dvd burner are not connected yet. network card, phone/fax, video card are not connected.

I am headed to the store to pick up a new battery CR2032.
