My acer notebook screen recently gave out suddenly. I can still see the screen albeit in a very dim way, so I do not think it is completely shot. But whenever I do something that affects the screen i.e opening and closing I hear a faint noise coming from the right speaker and then the dim screen comes up. I have it plugged into an external monitor currently which seems to be working at the time, although I am skeptical as to whether this can hold up. Little things have slowly been deteriorating on my computer (first my A/C cord was having problems them after one usb port broke the other no longer works). I have a three part question to ask: 1. Is there something I can do to it without having to spend on anything, as I am a tech savvy person, and assembling and disassembling is no problem. Maybe some settings I can mess with, anything really I'm willing to try. 2. If I do need to purchase something, what exactly do I need to buy, whether it be an inverter or something of the nature. 3. If I continue to use this external monitor, should I back up my files somehow, b/c I feel an impending complete failure of my computer coming as several things are wrong with it at this point.
