hi..
I suggested you to reset the computer using the reset pin hole at the bottom of the computer. Insert a paperclip into the hole and press for four seconds to reset the computer. The issue could also be with the Ac adapter, try to plug it in another wall outlet and check the issue.
If you have a unit from US or Canada, you may also live chat with an Acer technician at : Acer live chat If you have purchased the computer in any other country, you may contact Acer support here : Acer Global Support
