I know that this question may has been asked many times but here we go again.
I always had wanted to try the old thinkpad experience so I got one very cheap but in a rough condition. (Nvida Version)
Funny fact they forgot to remove a protective foil from the thermal pad so the chip was not cooled at all.
Model type is : 7663 - B22 S/N xxxxxxxx
Manufactured : 08/04.
It has a T7300. Bios version is from 2010.
Will this survivor accept Penryn processors like T8300 ?
Well, in my country Penryn processors are cheaper and easier to find.

Yes, it should work with no issues. I'd also recommend you to install the "Middleton BIOS" to remove any thermal error warnings and to unlock the SATA-II speeds.

I'd like to elaborate. It's possible you could have a merom only motherboard. The first Penryn capable motherboards were used in January of 2008. Yours was made in April of 2008. Odds are your motherboard is compatible but if it's not you will get a thermal sensing error because the merom motherboard cannot read the digital temperature sensor that Penryn CPU uses. In this application so sensor is redundant and the Middleton bios will prevent the error. If you install the new CPU and you get a thermal sensing error, hit the Escape key and it should boot. At this point install Middleton bios and you are good to go.
If you can tell me the part number of the motherboard I can tell you if it has native Penryn support.

curious how can you tell what support Motherboard (mb) has and where do you get this information? I have search my heart out looking for the clarifying sourse.
I have a 42w7652 from machine manu date 07/08 and cant find out much of anything about weither it is a dual supported cpu board or one of the merom only mb looking to use penryn cpu and prefer to use penryn supported board even if it means installing new mb rather than go the bios fix.

That motherboard will not support a Penryn CPU without bios modification. That motherboard also has an unreliable CPU chip. If you would like a motherboard with Penryn support I can get you one however it is a bit difficult finding one with the newer GPU chip. My recommendation would be to swap the motherboard with one that has Intel graphics instead of Nvidia. If you would like my help getting a motherboard please send me a private message. Since your existing motherboard is still working, one of the rare Nvidia survivors, I would recommend using it and plan on replacing it if / when the GPU fails. When you do the CPU swap be sure to use so fresh thermal paste and make sure you get a good quality brand.
I personally did the research and reverse engineering to determine which motherboards could or could not support Penryn CPU chips. I published a chart at t61. Wikispaces dot-com however that website no longer exists and the page was moved to the forums at thinkpads. Com. There is a link in the Forum at the top of the page to the t61 Wikispaces page. You will not find this information published by Lenovo or IBM anywhere.
Your production date is also a clue, the first two numbers are 07 indicating 2007, Penryn CPU chips were not used until 2008. Starting in January 2008 these models could have either motherboard however the ones with the improved GPU chip were used exclusively until August of 2008 and the series was canceled shortly afterward. I can still get these rare motherboards on occasion but they are getting fewer and far between also are getting costly. The Intel motherboards are still reasonably priced alternatives.
