In my acer aspire 1522 was a mobile a64 3000 (81,5W - 1,5V), i changed it to a simillar cpu only 3400, same watts and voltage. The machine runs fine but sometimes it gets very hot, now i have the opportunity to buy a real mobile a64 3400 with the same socket only the cpu has 62W and voltage only 1,4.
I have the bios 1.11 on my notebook, on the prior bios 1.09 acer mentioned in the read me: BIOS support AMD PowerNow function.

Which i think indicates that it should work, because the DTrs they build in have only quiet and cool and not powernow support. But on the other side it could also mean that the only support the mobile semprons like in a similar model aspire 1363 - is there a way to get ot which cpus are really int bios supported? thanks in advance. /blush.gif' border='0' style='vertical-align:middle' alt='blush.gif' />

It should work, but my main doubts are with BIOS & motherboard support since the mobile versions run at lower voltage than the DTR's. FWIW on the compaq r3000z/zv5000z people did successfully replace the DTR with the mobile versions but I am not sure about the Acer.

Also PowerNow and Cool n quiet are the same. I think desktops processors get the cool n quiet label whereas the mobile versions get the PowerNow label. in any case they do the same thing of dynamically changing the voltage and clock speed as an when needed.
