I dont know if anyone knows about this but i have an acer laptop and lately i have been having an issue with it. every once and a while, the computer screen will get slightly dimmer and the power button will start flashing. i'm not sure what it is doing or why it is doing it but its almost like it is unplugged but it isnt. it still runs on the cord and all i have to do is unplug it and plug it back in. i didnt know if this is something i should be concerned about or if i should just live with it. thanks for the help
