Hi,

I have a Dell laptop which has developed a fault. It doesn't recognise
its own power supply. A bit of internet research reveals that this is
a common fault on this particular model, and it's a fault with the
motherboard, so an expensive repair.

Sounds like a broken DC jack. Not that hard to remove the motherboard,
desolder the jack and replace with a new jack purchased from eBay. Or
have someone do it for you. It's not expensive work.

Plenty of web sites that will show how, and the service manuals are
freely downloadable from dell online.
