Well, mine is working fine so far, but i updated all the drivers first after i bought it using 3rd party software, so i didn’t check factory driver error.
Using it for downloading in public WiFi, campus life, and some programming. Heck i even using it as Oracle 9g server and XAMPP server since i need them. No faulty problem, WiFi is good, battery also good (around 8-9 hours), USB is good too.
The only trouble was when i updated the Sound driver with 3rd party driver updater, and it stopped working (fixed it with rolling back).
