Battery,Charger,HDD good
Worked at 1:00pm powered down than at 4:00pm would not power up. In between times computer just sat on desk.
Pressing power button & F12 key at same time causes battery light (right side) to come on RED & fan to run for about 10-15 secs than it turns off.
Tried removing battery run on charger same result
When pressing power button (Cap,Num.lock,scrol lock lights) along with HDD light on far right side come on for 2-4 secs than go off.
Removed memory,HDD,cd drive same result
What else can I try & have you ever heard of this problem before.
Thanks

I had similar problem on a used D600 I bought. Would power up when cold, but not boot immediately after shutting down (would restart okay). Indicator lights (3) and power light came on for a few seconds then all went off. Found what seems to work at another site. Not a fix, but a workaround: Hold F7 and F8 while pressing the power button. Like magic. Still, Caps Lock, Num Lock and 3rd light (scroll lock?) have been and still are non-responsive most of the time, but I can live with that. Hope this helps someone.
This appears to be a fairly common problem with this and some other Dell laptops. The problem is one or more poor (probably solder) connections between the power button and the circuit board below. Pressing and holding F8 & F9 and sometimes F9 & F10 and then pressing the power button work better. Can press down on panel just to the right of the power button and make the three indicator lights work, too.

You can try to replace the motherboard, which is apparently totally UnHappy

Press power button. Computer starts up. NO lights light up except the power button is on steadily. Fan turns on for about 5 seconds and then computer shuts down. You can hear the HDD running. Only way to turn computer OFF is to take the battery out of it and disconnect the power cord.
battery died, I plugged in power and restarted. I got black screen and sounds like hdd runs 10 sec and stops. how do I fix???
