See p. 20 of the Service Manual here:

 

Manual 

 

The motherboard only supports Celeron CPUs so there is no worthwhile upgrade you could do without replacing the whole motherboard. If you really want to make a project of it a better motherboard and processor for that model could likely be found for not very much money but the laptop is still just about obsolete at this point.

I think either we are communicating in the wrong language or you are just messing with me. The answer has been given. Good luck.
