Laptop does not boot
This started happening a few days ago. I have an Acer 5520 dual booting Windows Vista and Ubuntu Studio. Every time I turn my computer on, it will turn on and then just turn off. Sometimes it gets into the cycle of turning on, a second later turning off, then a sec later trying to turn on, to the point where I have to unplug it and pull out the battery to get it to stop. When it does this, it rarely gets to the start up screen with ACER in big letters with boot options again. Every so often I will get it to boot and it's just fine. Then like 5min into being in Ubuntu, it just shuts off for no reason at all. I'm not sure what is going on and I don't know how to fix it. Does anyone have an explanation for why this is happening and maybe some trick I can try to fix it? I really can't afford a new computer just yet so I'm looking for some way to get some life out of my notebook for just a month or two longer till I get a new one.
