Re: my dell 9400 wont.....
The impoortant thing is if the pc will P.O.S.T.? (This is what its called when the motherboard performs its initial checks) If it is making it past the dell screen and then goes black there is a component that the motherboasrd is getting that just malfunctions and causes the blackout. Most common is a bad hard drive, bad battery, or bad ram Try switching through thesre and see if that fixes you r issue

try starting it in safe mode....you do that by pressing the F5 key before windows starts up.. like right after you turn it on...once your in safe mode do a real good virus scan..i have seen that happen and it was a virus
you may need to change your power settings. it sounds like when you plug it in it goes into a mode thinking there is another monitor hold the FN key and press a key usually f5 that looks like a computer monitory. anyway plug in the pwoer cable, and hold fn and press the key that looks like a computer monitor maybe twice until the monitor comes back on let me know if that works!
First power the system on using Fn+Power and see if the diags run and you have video. If you have video in the diagnostics, then I'd suspect the video card as the failure point.
Also connect an external monitor and press Fn + F8 to activate the VGA port If you get video on an external monitor, I'd suspect the LCD as the failure point.
It shows no power on your laptop but it shows you the dvd player led comes on then off. I would suggest try the following:
1. Remove laptop battery, optical drive, hard drive and ram. Remove external peripherals as well.2. Make sure AC Adapter is not yet connected to the laptop. Press and hold on the laptop's power button for 10 seconds to drain the power flea.3. Connect the AC Adapter to a known good power outlet, check AC Adapter power LED if it is on. Try to sense if AC Adapter is not making a bit of noise when it is plugin to the wall power outlet.4. Connect now the AC Adapter to the laptop. Check if AC Adapter LED stays on when it is connected to the laptop. If the LED stays on means the AC Adapter is fine. If the AC Adapter LED turned off check the AC Adapter pin that goes to the laptop AC socket if it is loose.5. If AC Adapter stays on after connecting to the laptop try to power on laptop. If no power LED comes on then this is motherboard problem. 6. Before replacing the motherboard there is one checking needs to do. If you can open your laptop bottom part then good, do this when laptop is not connected to any power source. Try to reseat the laptop CMOS battery then try to power on laptop after, if still fails then replace motherboard. I hope this helps.
(before you do anything remove the battery and th ac plug)remove the memory inside small door on the backside that has a "M" on it now once you remove the memory install the battery, power on if you hear a couple of beep tones you are half way there the motherboard is good so the problem is what you took out so there are two memory slot try them in the A slot one at a time.If the problem is memory replace it.
First Run a diags on the dell laptop. You can initiate it by pressing fn+power button together and start the laptop. It will go to the diags screen. Tell me if the diags pass or not and then we will troubleshoot further. Thank you Rakesh Dell Laptop Expert
