Maximum PC

I picked up a Dell D800 last month very cheaply for my wife to use around the house. It has worked great until this morning.

Now, it won't power up. Nothing happens when I press the switch. I have tried it on both battery power and plugged into the wall.

No lights, no fans, no nothing.

If this was a desktop, I would assume the Power Supply was shot, but I know next to nothing about laptops.

Any ideas what it could be?

Check the battery and see if has a self test button, if it does what is the status?

Try the AC adapter without the battery, will it power up?

Is the jack for the AC adapter a bit loose? These DC jacks can get broken loose from the motherboard, sometimes you can wiggle the plug a bit and the system will power on.

If the AC adapter is 2 piece, you can disconnect the cord from the brick, then unplug and reseat the cord in case it was loose.

Try another outlet, or try another device in that outlet.

Otherwise, you will need to get the AC adapter tested, or have the power system checked out.

The simplest explanation is always the most likely.

After taking it apart, I found that the power button had come unplugged.

Glad you got it fixed.

I wonder if it happened to the previous owner as well, so they sold it.
