@BobWya: no CPUs are NO LONGER soldered onto mobos! That ended with Cyrix' chips! Both AMD and Intel chips have dedicated sockets for laptops. Yes they are harder to use than desktop mobos, but no, they don't prevent CPU upgrades!
Question is thus perfectly legit, and comments were more or less OK.
Now, case in point: if your laptop has a chipset revision that is said to handle more recent chips, then you may want to try. However:
- the only 100% surely working chips are those that are found as upgrade options for this laptop model: it means BIOS support
- anything more recent may, or may not, work; the best solution, is to get a chip, test if it boots, and keep the chip if it does.
