you can't upgrade a laptop processor.
Not true. Most you can but only a slight model or two faster than what you currently have. Usually it's not worth it as laptop cpu's are expensive and spending a few hundred dollars for an extra 200-400mhz isn't worth it.
OP, why would you buy a laptop and not choose a good processor at the start.
Double not true
I have an Acer Extensa 5620z. originally came out with 1.5ghz or slower. I upgraded the cpu to a T8300 (2.5ghz) in a matter of seconds. just a matter or unscrewing the access panel, unscrewing the heatsink and using a flat head to unlock the processor socket, pull it out, pop new one in and reverse above steps.
New processor cost me $45 second hand, and I sold my old processor for $30. so I got a 1.0+ghz upgrade for $15.
Quite annoying when looking for info and people just chuck up a NO to cover everything when its clearly quite a laptop specific answer
