I recently got this laptop and ever since I got it I've noticed that the screen is always dark. The only time I've noticed that it is at it's full brightness is when it is plugged in. Is there a way to make it have this full brightness when it is not plugged in?
It sounds like a setting. Either in "Control Panel" or you can try by right clicking on the desktop background and then in the popup list click "Graphics Properties". You can then check the brightness settings in there.
