1) I tried connecting my monitor to the laptop and I´ve had no success.
2)Regarding the drivers, I`m afraid I didn´t pay much attention to them the only thing I remember was that the update was triggered when I installed directx 9.0c.
3)Sadly, the computer is silent as if it were idle or asleep, but the lights are still on. If you are talking about windows sounds, forget it, I don´t hear a thing 😛
4)Tried and had no success. I even tried disassembling the damn thing.
