Re: Dell Latitude D800

You have a short circuit. Try powering up but with the battery out.

Re: Dell Latitude D800

I had the same problem with one of the old dell laptops.I knew what went wrong cause I got quite pissed off with my laptops speed and banged it hard. Then it stopped working. So I decided to open the laptop(Need to be brave and have some knowledge ).After trying everything I finally found that the processor has come loose. So put it back into place , then the laptop started working. Your problem might be the same, could be a loose connection,

I need to unlock a bois pass word for dell latitude D800

The best way to unloc a BIOS password is to reset by removing the CMOS battery and while the mains is removed press the power button a few times and leave for about 30 seconds. Refit the battery and power up. Password should be removed.

My dell latitude d800 dosnt start. no cursor no splash screen ..only lightning some buttons..


If you see power lights but nothing appears on the screen, it could be a "POST" (Power-on Self Test) problem or simply LCD problem.

Here are some steps that you can try. One of these may work on your case.

1. Remove the battery and the ac adapter then press the power button for at least 20 seconds to drain electric charges left on the system. (You may need to repeat this step to get it work.)

2. If above step doesn't work, try to plug in an external monitor and see if you get display from the external monitor.

3. If you get display from the external monitor, I'm sure your having problem with the LCD components. In this case, check and replace faulty LCD backlight, LCD cable or LCD inverter. The LCD inverter is often a culprit.

4. Try to reinsert the memory module/s (RAM) of the unit, try using one RAM at a time to see if it works. A faulty RAM will cause the laptop not to POST.

5. If reinserting the RAM doesn't help, most likely your motherboard needs to be replaced.

Hope this helps.

Hi there, my six year old dell latitude D800 lcd goes dark (not completely, but unreadable); (first brightness was jumping down and up). Two years ago I had such problem and solved by replacing the lcd...

Sorry to hear that, Paul. As far as notebooks displays go, the light behind the screen is the part most likely to go out. It generally does just that: it just goes out, though the screen itself works (the LCD is still generating a picture, which you said you can still see). Whether you run it dim or bright doesn't play much of a role.
Another inverter replacement is probably needed here, with the light itself (what the inverter is powering) an somewhat less likely explanation. In any case, the notebook will have to be opened up to do the work, where is where a lot of the cost comes from (unless you or a friend is doing the work for you).

Good luck!

I Have a Dell Latitude D800 and it's plugged into power. when i hit the start button it lights up a couple of lights on the keyboard, they go out after a couple of seconds and then nothing happens?

Is the battery charging? and is the power adaptor properly plugged in? If yes then it's probably a faulty PSU and you will need to phone DELL for a replacement/repair.

My Dell Latitude will not turn on. When I press the power button it will come on for 5 seconds then go off. Can anyone help ?

Plug in the AC power cord, remove the battery, and try powering up. Anything? Any lights?
Remove power cord, hold in the power button for 30 seconds, then try plugging it in again and powering up without the battery. Any change?
