Dell inspiron 6400 rebooting

I have recently taken out the system board. After I turn it off it will reboot , not immediately but anytime up to 30 minutes afterwards. Strange
I have checked that the wires are back in the original places. There must be a short, or something.

Anyone come across this problem before?
What would I check?

    Its not the software. When it boots up it works perfectly well.



    It is not the cooling. After reassembling the laptop, heatsink paste was applied and it runs at a cooler than average temp.



    The computer restarts approx 30 mins after its been shut down.

    I am going to open it up again and see if there is a short.



    Just thought someone may have come across this problem before - i had updated the BIOS recently as well.

That kind of rebooting problem is usually a hardware conflict. Make sure all the boards and cable are plugged in right. Also, remove any addons like extra RAM chips while troubleshooting.

Otherwise, it could be a faulty part. MB, RAM, video card, etc.

Lastly, it could be a corrupted hard drive.

Good luck.

You took out the system board for what reason?
did you remove fan and heatsink and when you put it back together did you put thermal compound between processor and heat sink? sounds like machine may be overheating due to lack off thermal compound or dried up compound

My Dell Inspiron 6400 (Windows XP Home) won't reboot. It's giving me a "Loading PBR for descriptor 1 ... done" line on a black screen. What can I do to fix it. Can I salvage my content / files


Before you use the Recovery CD you need to backup your data because to restoring your laptop will wipe your data off the hard disk.
To backup your data when you cannot boot up your laptop, remove the hard drive and connect it to an USB hard drive adapter. Connect this hard drive/USB adapter into the USB port of a working computer. The computer will see it as an external storage device, you can then open the folders and backup your data.
You can then fit the hard drive back into the Dell laptop and boot up with the Dell recovery CD to reinstall Windows etc.

Multiport communications port(COM4)


Unless it's affecting something directly you can just leave it be. It's probably just a simple driver issue.

If you do in fact want to "fix" the problem I'd start with just uninstalling the device in the device manager and then reboot the computer.

Did you recently re-install windows? When did you notice this problem?

Touchpad not working


Hello, my best solution would be to check ebay and order one there. If you are familiar with removing the power button bezel, do so and remove the keyboard as well. Then check the connection for the mouse. Its a small little ribbon cable coming from the mouse area.
Here is a direct link you can get these parts from:

Errorcode 2000:0221 / 4C00:041C


Have you tried rebooting and pressing f11 several times immediately up on reboot. This will give you the option to restore to Dell's System restore. If this does not work for you let me know. I have it had work for previous client's.
