P-II Dell laptop
I have an antique of a laptop that only enters BIOS, no OS. (though I have run puppy Linux live mode) But I depend on this machine quite a bit.
This is because I have a newer Dell laptop that I do use, and it's battery charger doesn't work. As it happens the older one has the same batteries and the charger works.
So basically I have a battery charger with 101 key keyboard and a 9 inch LCD screen.
