text: please help me.....asap? my laptop don't want to come back on. i checked the battery's life and it is 15% available. now, i'm using the ac adapter, but it still don't want to come back on. what should i do? what is going on? do u still a battery eventhough you are using the ac adapter? if not, what can i do to make it come back on? try taking the battery out completely, make sure the ac is plugged in then turn it on. -or- reset the battery.
