well notebook drivers are likely to take sometime to update for windows 8. this happens usually after every windows update. windows xp to windows vista was similar headache. though windows 7 drivers should have worked just fine on windows 8.
Yeah. Most (if not all) drivers installed in my system currently are Windows 7 drivers. Even the Bluetooth is working fine. After reading Samuel's post I felt that even my Bluetooth won't work properly. Just tried it and it's working perfectly. The only driver related issue for me right now is this mousepad not unlocking thing.
