Do not see any power lights on the front? - Maxtor Personal Storage 3100 (M01E100) 100 GB Hard Drive

The lights have stopped working on the panel on your washing machine.

Hi RORY CALLOWAY-GOUZOULES, try removing the power to the unit at the power point.
Wait 20 seconds and power it back up at power point and see if power button on front of unit will power it up.

I'd say that you have exhausted your options. You can try to isolate the power on problem by removing your your memory modules, hard disk drive and see if it at least stays powered on. Here is a link from Dell for your laptop's manual:

The front park lights work correct? If the front park lights work than there is not a problem with the light switch since the brown wire from the switch supplies power to the front park lights, front side markers, and the rear taillights. There should be twelve volts on the brown wire from the headlight switch with the connector plugged in and the park lights turned on. If this is true that there is a problem with the wiring to the back of the vehicle. A thorough inspection of the harness should reveal the problem. The dim break and blinkers support the above. High resistance also know as corrosion, in the wires or connections would cause this problem.
