I can't say for your specific laptop but I recently installed Win 7 Pro on my Acer Aspire One A0A150 netbook. Acer did not have any Win 7 (or Vista) drivers
available on their website for it. Win 7 installed drivers for everything except the multi-card reader but I was able to find a driver
for that and install it to make my netbook 100% functional in Win 7.
