Upgrading a processor in a laptop is a lot harder than in a desktop. I doubt you'd be able to get as good a thermal seal on the new processor as the manufacturer got on the old one. In addition, as far as I can tell, the t9900 is not compatible with the same socket(s) as the t7700, so it probably wouldn't work anyway, and even if it did, the performance increase would barely be noticeable.
