Hello guys, I am using Acer TravelMate 4200 from last few months and it is running Windows Vista Operating system in it. Everything was working smoothly with my laptop till yesterday night. But from today morning whenever I try to close the DVD tray after using the DVD drive, my laptop shuts down automatically by itself without any warning. What could be the reason behind this? Does anyone have any solution to solve this problem of mine? Please help me by posting your kind suggestions.
