T61 7500 Upgrade

I have a T61 7500 2.2 ghz laptop. Is it possible to replace my 2.2 ghz processor with a faster one, without replacing the

motherboard or anything else?

Hi, and welcome to the forums!

 

What you currently have is a "Merom" CPU, upgrades include a T7700 (also a Merom) and Penryn CPUs (up to a T9500). Both types of these CPU's (Merom and Penryn) use socket P and work using the same motherboard chipset (GM965), so theoretically it should be possible.

 

However, unless the Penryns require some additional thermal IC for proper function -  such an upgrade would depend on the motherboard revision, the newest version mobos already carry all hardware fully supporting Penryn CPUs, earlier version mobos may not. A BIOS upgrade would also be in order.

 

Would be best to get input from a Lenovo engineer on this one for clarification on motherboard revisions and Penryn upgradablitlity on the T61 series system boards.

 

Hope this helps

Re: T61 7500 Upgrade

I believe this was answered on the Thinkpads.com forum a few weeks ago.  There was some issue with a "thermal sensing error" using the Penryn CPU.  Do a search on Thinkpads.com for this.
