Lenovo T61 - Discrete to UMA

[ktmmotocross]

Hello.
Have this laptop Lenovo T61 with nvidia GPU with black screen and one long beep and two short beeps.

It is very known GPU issue, so i have in mind if it can be converted to UMA

Best bet is to replace the GPU with a fixed revision. White underfill, datecode > 0830

Re: Lenovo T61 - Discrete to UMA

is it worth it?

for reball i charge 30e, service charge another 30e from customer and chip cost minimal 30e

and i dont have good seller for that ic

Lift the chip and start the board like that. It doesn't work?

Its cheaper for the customer to put in an intel board.

If nobody did it before on the Internet, this mainboard cannot be converted to UMA.
