You're laptop has a processor that is a few generations old. I'm assuming this is the processor you have: ARK | Intel® Core™2 Quad Processor Q8200 (4M Cache, 2.33 GHz, 1333 MHz FSB) or maybe this one: ARK | Intel® Core™2 Quad Processor Q8200S (4M Cache, 2.33 GHz, 1333 MHz FSB). If your laptop has a socket so that you can swap the processor and if the BIOS of your laptop supports the "upgraded" processor, you could theoretically swap processors. You would have to get a processor of the same generation as the processor you have. You would want a processor that doesn't have a higher TDB. You might find one that has a faster clock frequency and bigger cache. But I wouldn't expect to get a really big performance boost.
Computer performance has come a long way since your computer's generation, so you probably would not be happy with upgrading your processor to another processor from the same generation. If it was me, and my computer didn't perform at the level I needed, I would buy a new computer instead of thinking about upgrading the processor.
