Hi everyone, i just replaced my 2Ghz CoreDuo in my T60p with a new 2.33 core2 duo T7600; the computer won't start. I went back to the original processor and disabled the security chip and retried and still nothing...
My bios is 1.10 with i updated yesterday from lenovo support, obviously could not find the 2.0 bios which has been removed from their website as mentioned in this forum.
Any ideas?
Is the bios 1.10 not able to recognize Merom Core2Duo?
Is there anything else i missed?
Also, does anybody have the 2.0 bios they could point me to if i need it?
Thank you

Just found a link to a chinese driver forum and downloaded the 2.01; i upgraded bios and reinstalled t7600 and now it works like a charm.
Thanks

Hmm that doesn't sound good at all. Am I understanding what you posted correctly that with BIOS 1.10 installed your computer would not boot. That you then replaced the T7600 with the original T2500 CPU and it still wouldn't boot?

If so then how did you update the BIOS?

I hope IBM has not removed the 2.01 BIOS because it does support the T7600 and they don't want us to have that feature with out getting it through them.


So did you run any test, before and after? What does it feel like, does it make a difference? Where did you get the T7600 from?

Thanks

It seems you mixed something up. Anyway. He put the "old" CPU back in slot when the T7200 wouldn't run "the course he wanted to play". Then he did some BIOS adjustments but it didn't has any effects.

1- I had bios 1.10 starting
2- I replaced the T2500 with the T7200 and the computer would not start
3- I replaced the T2500 back in and computer ran fine as usual and then I upgraded to bios 2.01 which i found online at a chinese driver forum (used online translation)
4- After upgrading to 2.01 without problems i shut down and replaced the T2500 again with the T7200 and the computer now started fine and has been running very well since.
5-I did not do any benchmarks but subjectively seems slightly faster but not blisteringly so.
I hope that makes it clear.
I do think that Lenovo pulled the 2.01 to make upgrading less easy to the end user until they have sold some of their own machines preconfigured with Merom.
I got the T7200 from Newegg for $650, PC connection and CDW also have them for a $100 more.

How difficult or easy is it to swap out the processor? Removing the heatsink tricky at all?

No, it was quite easy and i had to swap 4 times total, you should really have thermal cream/paste handy because everytime you remove the heatsink you have to clean the processor and the heat sink contact surface and apply a thin layer (at least i did). Make sure to download the lenovo t60p instruction manual search for link on this forum.

Just ran sisoft sandra and it bencmarks dead-on with expected result, also emt64 is enabled

Kudos on the pioneering effort!

$650 - ouch!

Could I talk you into putting the T2500 back in long enough to run some comparison benchmarks?

Better (read: more practical) idea -- Is there a set of benchmarks that you can run on the T7200 and that I can run on my T2700 to see the direct effect of going to Core 2?

I Googled "sisoft sandra" and it looks like that is commercial software for which I don't want to shell out $s.

catdog,
when you pulled off the heatsink, what did you do with the GPU's cooling compound? Have you replaced it with thermal grease too? How about the GPU's temparature?
