ThinkPad T21 Motherboard

Hello.

A friend of mine has given me his IBM Thinkpad T21 to fix for him.

It won’t boot, just gives a 0175 error.

I know it will need a replacement motherboard but i am having problems finding one.

I was wondering if it is only the Lenovo ThinkPad T21 (12P3366) Motherboard that will fit into this laptop? Or are there other motherboards that will fit into this laptop?

Thank you in advance,
Sam.
