    I have tried most of these solutions- i pretty much figured it is something internally... I have tried different ram and power cord(I have several donor computers) I have also tried without a battery - nothing happens: not even a battery light then. Could be a power switch

Most likely cause...motherboard has burned out. But try reseating your RAM , and removing your battery with the power cord removed. Press the power button to drain and "reset" things. Reinstall the cord and battery.

If it still doesn't start, try another charger. They can partially fail so they appear to charge but don't have enough power to run the machine.

Finally, try replacing your power switch. This sometimes fixes a starting problem.

Motherboard replacement will cost as much as getting another D800.

Check the status of the battery directly from the battery. Turn the laptop over and on the batter is an battery indicator button and lights to tell you if it's charged. If it is charged then you have an problem internally. Wiggle the tip of the power cord at the laptop connection to see if it is loose, if it is then you have an loose connection on the motherboard which can be fixed by an experienced tech that can solder or the motherboard will need to be replaced.


IF THIS HELPS PLEASE VOTE.....GOOD LUCK AND THANKS..

Hi,

Take out the battery and try booting the machine on AC power only. If the machine boots up then let the operating system load up, the shut it down. Remove the AC jack and put the battery back in again, then power it up.

If it boots all is well if it doesn't then there could be a problem with the battery.

Please let me know how you get on and good luck.

    Hi,

    I have to agree with mrogers59.

    It is most likely the motherboard which is at fault here. If the laptop has a power board (a separate board that comes away from the main board with power switch on it), you can always swap one out from one of your donor computers.

    If its part of the motherboard then chances are the motherboard has developed hairline cracks on solder on the parts that get the hottest. The usual places are the power point on the motherboard, GPU (graphics processing unit) and so on.

    you can always try removing the BIOS battery from the motherboard for 20 minutes to see if clearing the CMOS works.

    Other than that you could try swapping motherboards from the donor computers that you have.


    Regards.

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.

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.

D800 will not even boot


Okay, I had that problem with my HP less than a minute ago.

Maybe it is the same problem. See if the battery light comes on. Press the power button again and again if it doesn't start, for some time. It may show the boot screen and hang. Now, the battery must be charged. Shut it down directly and switch the AC off.

Now, switch it on and see if the battery light comes on. If it does, it is the same problem as mine. Now, turn the PC over and remove the battery carefully. There may be switches for that.

Now, plug in the AC and start it without the battery in. If it does, you're done. Now, plug in the battery again.
