So normally my laptop will make a kind of high pitched beep when I plug anything into the usb port, and will make a low beep sound when I take it out. but lately it keeps making the low beep all the time, randomly and for no reason, even when I have nothing plugged in. and sometimes it will even give me a warning message saying that the laptop cant read the device in usb port whatever, especially if nothing is plugged in. I got this laptop last july and it has been reformatted once, about may this year, and it has only started this weirdness in the last month or so.
Also when I unplug the computer and use it on battery power, after a few minutes the screen will go blank. everything is still on, it's not in sleep mode, but I have to close the laptop, wait for it to go into sleep mode, then open it back up, and after that it doesn't do it again. this started around march. its not really a problem (unless you guys think its a problem) its just kinda annoying and weird.
any thoughts, suggestions, or solutions that don't include a $100+ trip to the store?
