Short answer: Yes.

Long answer: The CPU is usually not considered to be a CRU (="Customer Replaceable Unit"), like e.g. the keyboard or memory modules, so only a certified service technician may open up the machine without voiding warranty.

But if you are able to do it very carefully without leaving any noticeable traces, and keep the old CPU around in order to swap it back prior to to have the machine being serviced under warranty, then this should be a minor concern. Personally, i wouldn't want to submit my still valid warranty to the risk of being voided just by a dumb negligence on my behalf while trying to do as described, and i definitely wouldn't recommend it either. But after warranty expiration, nothing would be able to prevent anyone from repairing his/her own machines to one's heart's content.

Thanks ,rumbero !

Guess its worth more to extend warranty before it expires than any "small" enhancement got by
T8300 -> T9300 (increase 0.1Ghz + 3MB L2 cache)

A faster drive, like the Mometus XT, or SSD is probably a better path to make your machine feel more responsive. Typical notebooks usage i.e. Office and Internet do not push the CPU much, but faster boot times and application launch times will much more noticeable.

Just make sure that your laptop is actually eligible for a warranty extension...

AFAIK, some of the T61/p model numbers were "blacklisted" at one time, stripping them of the ability to get the warranty renewed...
