i bought a very cheap hp2133 recently, but it was fitted with a painfully slow via c7m 1.2ghz...:\
unfortunately, hp decided that the cpu's were to be soldered in, so you cannot even change them. i know i open the whole thing up had a look..
pff...pc's can always change their cpu's?!
btw, if you are a hp2133 owner, you can remove the internal plastic grills from the hot air exit points and improve air flow and therefore temperature, by a not inconsiderable amount.
also the thermal paste hp use is more like plasticene. remove all this and get some proper paste on there and the infamous heat problem of hp2133's is improved.
why do all sorrts of laptops seem to have their exhausts going downwards from the back, so basically you heat your er, lap? why not have the go straight out the back or up thru the lid or something?
anyway..someone is working on changing the cpu for the hp, worse ways i could slap a 1.6ghz mobo and cpu soldered combo in there, but not even sure if that will be enough..or sell it to someone and wait for something with beef to come along ^^
