Ok here's the problem. I am on vacation and the only way for me to connect to the internet is to go to the local town library. So this morning I unplug my computer from it's AC adapter (and the battery is at 100%) close the screen and head to the library. I get to the library and the computer has shut itself off as opposed to being in standby mode which it has down for the past two years (being in standby mode that is) that I have owned the laptop. I move the mouse around try hitting the spacebar/enter etc. and nothing happens, no lights are on, no nothing, just a black screen. I assumed that it has somehow turned off by mistake and hit the power button...nothing happens. I tried this about four or five times, no lights flashing, no sounds from the hard drive working, no nothing. I do not have the AC adapter plugged in, but I don't this this should matter as I have unpluged the computer and transported it without AC and then resumed use of the computer at a different location with no AC power and it works fine (until the battery dies of course, if it's disconnected long enough for this to occur). I'm going to try to turn it on again with AC power when I get back to my house, but I would still like to fix the problem that it is having so I can use my computer with an AC cable. Thanks for you help.
