I have an Acer 5755g with i5 vPro and 4 gigs of ram; windows 8.1 running on it.
following are the problems; which made me come out and post a question over here
1. brightness can never be adjusted
2. can never connect to the WiFi

i use UniBlue DriverScanner 2014 to scan and upgrade . . .
removed and reinstalled the drivers and the hardware ten times literally !!
pls advice . . .
thanks in advance
