so i upgraded my laptop's T5250 (1.5 GHz C2D, 2MB cache) to a T7500 (2.2 GHz C2D, 4MB cache). it took 3 hours. i lost no screws, and everything appears to work okay. still: WHAT A FUCKING PAIN IN THE ASS. hp/compaq laptops used to be EASY to update -- almost trivial, even. this dv9500-series was a fucking bear -- i had more weird-ass screws, bits of plastic, and odd cable ends ever. i had my wife play "operation" with screws i lost in the housing twice, and i used 3 of my 5 jeweller's screwdrivers. but it is done, and now i run company of heroes like glass on it. hooray for me, or something.
