Well the laptop is a Sony Vaio powered by AMD E-450 APU HD6320 320gb, upped ram 4gb. The original package came with Starter 7 32bit and some bloat. Reformatted it to Home Premium <unfortunately it's 64 bit> and have mostly covered most device installs. Having used the laptop before install, it has visual indicators for volume adjustment and brightness adjustment when pressing the Fnc + F keys. Also only the Fnc + F keys for sound adjustment works, brightness doesn't change when pressing the function key plus the appropriate F key to adjust brightness. Is there a way to get them back? Or it's a factory thing? <Haven't deleted the OEM recovery sector so I can go back to the default OS installed> Sorry it's my 1st venture to mobile computing , have been on desktop eversince Edit: BTW Thanks in advance.
