XPS 400 will not boot

This question is not answered

Have an XPS 400 configured with Win home server s/ware. Turned off while away from home. When I pushed the power button would not start and the power indicator light just flashed on and off until power cord was disconected. Any Ideas?

  • Here's the Troubleshooter for the XPS 400.

    What color is the blinking power button?

    Do you see anything on the monitor, like a flashing cursor in upper left corner?

    What color are the 4 diagnostic LEDs when it won't boot? Look up error codes at the link, above.

    When was last time you replaced the motherboard battery?

  • blinking power light is Amber

    Monitor is completly blank, no flashing ciusor.

    Diagnostic lights flash briefly when power button first pushed, then no leds.

    Replaced the mother board battery, still same.

    The fan on the video board spin when power is applied and then stop.

  • Soundling like it might be a power supply issue.

    If you use a power strip, surge protector or UPS, disconnect those and plug the PC directly into the wall. Maybe try a different wall outlet too.

    If you system has it, try moving the voltage selector switch on rear of the tower back and forth a few times. Be sure to UNPLUG the system first! And be sure the selector is set for the correct voltage before you plug it back in!

  • Checked the PSU and only getting voltage from one pin on the M/B connector. Replaced PSU and it's up and running.

  • Same thing happened to me. When this type of problem occur. It is usually due to PSU failing or a possible GPU problem.
