ThinkPad T61 7664-1KU - cpu upgrade T7500 to T9500 - possible? [ Edited ]

@AndrewTo, what do you want to know? whether you still have warranty or whether your laptop supports T9xxx Penryn cpu?

P.S. T61 is already 4 generation old.

@lead_org

yep, I desperately want to know if my system is compartible with Penryn, for cooler n prolly longer battery life.

T61 is too old I know, but itz also an excellent machine dat no one wud want to abandon it (except for itz weight n battery life)

Also wud like to confirm dat 7663 can run modified BIOS 2.27-1.08 to unleash SATA2 (http://forum.notebookreview.com/lenovo-ibm/459591-t61-x61-sata-ii-1-5-gb-s-cap-willing-pay-solution-...)

thank u very much!

The modified bios should be compatible with all the T61 and T61p, however you install it at your own risk.

Well whether your motherboard will natively support penryn cpu, depend on the FRU number of your motherboard. You can check here

http://support.lenovo.com/en_US/product-and-parts/partsLookup.page

The modified bios will allow you to run the penryn cpu even if your motherboard does not support digital thermometer, however it will lose support for thermal overload protection. So if the CPU overheats it will not trigger an automatic shutdown.

@lead_org

thank u very much!! sorry abt off topic

I'm running official 2.27, cud u plz advice a way to flash the non-official BIOS(also 2.27 if I'm not mistaken) bypassing version check, or downgrading to previous ver?

"flash2.exe /u" dis command not working, it says:

"Checking files and environment... done.

Start flashing...

Error during flash. Error code = 99 (179) 

!!!Updating your bios while Microsoft BitLocker drive encryption is enabled will cause subsequent boots of the encrypted drive to fail. if you are using BitLocker, plz refer to BitLocker help for info on how to temporarily disable it b4 updating ur bios!!!"

prob is, non of my drives r enabled BitLocker (Control Panel > Security> BitLocker)

or maybe wait for newer version to be released(Middlton mentioned in 4thMay2011 dat he will not)

again, the links of lenovo(parts checkup, warranty checkup) cannot recognize my SN, "* 07/09" printed beneath my laptop(I hv no prob on reading it as the lable is intact), I tried many combinations (with or without hyphen, with or without spacing, with or without 07/09, capital letters etc)

in Lenovo ThinkVantage Toolbox:

Product: 766313U

Serial: *

BIOS: 7LETC7WW (2.27)

Warranty: Could not be determined

Hi AndrewTo,

If your serial number label is hard to read, try this software method suggested by goretsky:
