i did install for few CQ40-115AU
and CQ40-125AX

and i recommended Vista

the common problem both on Vista and XP is the "Tett" sound
just XP the sound quite irritating and for Vista just smooth sound

for drivers.
i will try update you all regarding it soon
just want to share..

and one more thing..
while i was installing CQ40-125AX in VIsta
there is 2drivers not available for Vista
Wireless - Broadcom
Webcam - Cyberlink Youcam

yaa already out
the price is similiar with CQ40-125AX
huhu

who bought those last unit 125AX must be frustrated
