Help with a T23 lower unit and T20 parts

[rmojo2]

I have a technical question: Will the HD, memory, keyboard, LCD, and the memory door from a T20 work with a lower unit (laptop motherboard, encompassed by its base plastic housing) of a T23.

The T23 lower unit is in working order but the T20 has a bad mainboard.

Thanks in adavance for any advice.

use a more descriptive subject line and you might get more people reading your thread.

There are quite a few differences between the T20-T21-T22 TPs and the T23. For starters, the T23 uses a different chipset, PC133 memory and has 2 USB ports instead of the 1 on the T20.

Check this web site for a list of T20 to T22 parts:

And this one for the T23:

Also get the IBM Hardware Maintenance Manual for T20 to T23:

Keep us updated on your results.

the T23 lower unit had the base plastic motherboard and CPU. The T20 has everything except a working mainboard. I knew about the Memory being 100 in a T20 and that the T23 uses 133 but will all of the other components together create a working unit?

The Fan/Heatsink on the T23 TPs are different.

Does the T23 base have the I/O Card? The T20-T22 TPs have a single USB outlet, the T23s have 2 outlets.

The keyboards are the same and the screen and lid should interchange. The T23 may have a built in wireless antena.

Did you check and compare the parts lists on the sites I recommended?

That should give you some guidelines.

Good luck.

Yes the lower unit has the i/o card so If I can get it I think I will.
