Last night something was rattling around in my laptop, which had been happening for a while, but this time when I picked up my laptop the thing slid to the top or bottom of my laptop, I can't remeber which, and my laptop shut off. I thought that it would turn back on, but when I tried to it won't. I tried taking out the battery, shaking my laptop, blowing on it, but it won't turn on. Please help.
