Q: I was picking my laptop up from the florr and dropped it, my hand gave out on me..It was asleep and when i brought it back and got online, while o was online the screen went dim, it scared me to death, after checking i seen it was unplugged and was running on the battery so i charged it to 100 percent and had to go in and set the brightness to high, i’m not sure but i thought it regularily was set at half brightness, but i’m not sure..How can i know if all’s well and that it’s ok to set it at high brightness…
