Half a second is much to soon for a Windows problem to show. So contact Dell tech support and arrange a repair.
Dell inspiron E1505 running Vista home. Wife turned it off last night and this morning it won't start. No prior problems.
On pressing power button, Dell flash screen comes up for about one half second, then black. Indicator lights on right hinge:
- power light steady
-read/write light flashing
-battery light off
I've tried two power cords, no change. Battery out with power cord, no change.
