I'm in a bit of a dilemma. So, the keyboard on my cell isn't working right, and i have a Thinkpad. I was wondering if I could use the Thinkpad keyboard for the Dell? The Dell has Windows XP, and the thinkpad has a corrupted Ubuntu install, hope the Thinkpad can be used for something like this until I pick up a USB keyboard, or is this possible? Thanks. A laptop CAP use a standard USB keyboard. But using a Laptokey board to drive a USB cable is another thing. It is very difficult.
Short answer: No
My assumption is that you need a keyboard to change things in the BIOS. Is that so? That makes if very difficult. The BIOS wants a real keyboard.

The long answer belongs the the category: 'You said it could not be done'

Short answer is No...UNLESS they are both the same manuf. keyboards it simply won't workAdditional information:

From this you can see they are very specific. They have both mechanical and layout variations. Notice how many there are for just the Dell laptops.

If necessary, most laptops will be usable i if you plugin an EXTERNAL standard USB keyboard. But some special functions will not work.

You have to get the OEM keyboard for a perfect replacement.
