I have a hp ze4430us with the mobile athlon xp 2400+ processor and would like to know if it is possible to upgrade to a faster processor. I downloaded and read the manual from hp but the spec section curiously omits what type of cpu's were available for the 4400 series.

I'm having some heat issues (along with a dead hd) and will be opening up the laptop to clean and reapply thermal compound and figure it's as good a time as any to upgrade.
