I have never had a problem with my laptop until this morning. Yesterday, it worked fine. I plugged it in when I went to bed so that it would charge and be ready to go this morning. When I unlugged it this morning and tried to turn it on, it wouldn't do anything. So, I plugged it back in and it came n when I pushed the power button. When I unplug it, it shuts down completely. If it is my battery, shouldn't I have had problems with it holding a charge before now? This is just sudden! Work fine one day and not at all the next.
