Warranty expired last spring. When I power up, the screen goes black around the login XP screen. I pull the AC cord out and try the same thing off just the battery and it's fine.
I tried another power cord from out IT dept. at work and it does the same thing. I also tried using the machine AC without the battery and no luck.
All power settings are normal.
What's the problem?

Re: Screen blackout when using AC cord
I think you're goin to have to replace your" dc-jack" as it's called. This is where your AC cord plugs into your laptop.DC-jack problems are very common in laptops.Over time they wiggle loose just enough to mess up the solder connection on the motherboard.Try gently wiggling your AC cord where it plugs into your computer ,if you screen returns to normal when you wiggle the plug a certain way,then you've most likely got a bad dc-jack.

It sounds like the back light power inverter is triggering a safety feature, perhaps due to a fault or bad charging system. I'd first contact Dell to make sure you're using the right power adapter for your unit. Enabling a bios pdu scan that's resulting in a message such as the one you described WARNING: 130WATTS ADAPTER DETECTED, U MUST USE A 210W OR HIGHER ADAPTER" THE PERFORMANCE WILL ADJUST TO MATCH THE POWER OF YOUR ADAPTER" is a hint to a larger problem so, if that's all correct take that to an authorized dealer and swallow the cost. Remember that's a workstation so lifecycle services may be having issues with the brick.
It sounds like your backlight is damaged.
On some units this can be replaced on its own. On others, it requires the entire LCD to be replaced.
I'll see if I can find out which this is, in your case, and find you a part number.
If you power it on and you see an image but it then goes black, that means your screen and components is/are working fine. There is a loss of "communication" from the motherboard to the video controllers and drivers to the screen. If you do see an image for a split second at bootup but it then disappears, your screen is fine. If your screen was bad you would not see anything. I suggest you not spend a dime with that "expert" because it sounds like they are just trying to make a buck. It will not resolve your issues by replacing the screen.
Here are a few things you can try:
* Pull the battery out of the laptop and remove the power cord. Press the power button and hold it down for 20-30 seconds. This is to drain any and all residual power from the laptop. Then release the power button, put the battery back in, plug back in the power cord and attempt to power up.
* Keep screen at 30 degree angle (just wide enough to reach in and press power button). There could be a malfunction with the sensor that detects the lid being open or closed. Once the power button is pressed, keep the lid at the angle (partially closed) and see if it boots up. Give it a full three minutes or so to see if it works.
* Try the combination of the function keys that are meant to switch the display to external.... It is different for different computers. Normally it will consist of something like FN + f4. Try looking for the little icon to indicate an external display. You can also try using these combinations of function keypresses: Alt+Ctrl+F1 and Alt+Ctrl+F3 and Alt+Ctrl+F11
* Check and see your display hardware/drivers/onboard controllers functionality - if you connect an external display you should see your desktop without a hitch.
If none of the above helps, please let me know and I will continue to assist you in troubleshooting.
Your screen inverter is failing or has failed. Remove the bezel from around the screen and the inverter sits under the screen and is atached by two plugs. The inverter takes DC power and converts it to high voltage AC power to run the lcd backlight. Yours is failing. These are 20 bucks on ebay. Remove the rubber plugs around the bezel that are covering the attaching screws, remove screws, pry the bezel off the frame with your finger nails, use caution and wirk a corner first, then work your way around the screen. Look below the screen and there at the bottom is the inverter...unplug at both ends and replace with a good one.
Are you running on battery or AC? Try using the power cord, remove the battery and see if it continues. I have seen a battery that is on its last legs do some weird things to a computer. Also, check your power management setting. Control panel, power, and set the computer to "always on" just to see if it could be a power management setting. If none of this works, i would back up all your files, and try to reload win xp from scratch.
your wires connecting from your laptop hardware to your display is messed up and is only "re-connected" and "hot-wired" by your action of closing/opening the lid.... use your warranty... your problem is when your warranty is expired so be glad this happened when you still have warranty
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
