I have two Lenovo thinkpads and the other one I had pretty much had a bit of a black-screen meltdown earlier for some odd reason, I wasn't doing anything 'dodgy' to it or with it, I was just checking my messages on Deviantart when it suddenly came up with a black screen. I restarted it and pressed the power button to turn it back on again but the black screen popped up, there wasn't a cursor or anything on it. I couldn't turn my computer back on. And I don't understand why this happened. I had my computer updated yesterday and that worked fine...so what is wrong with it this time?
