I haven't had this computer six months yet and the computer shuts down on its own and the power button blinks. If the machine isn't plugged in it shuts down and it won't start even with a full battery charge; the machine will shut down. I am beyond disappointed. This is NOT a cheap machine. Now here I am having to send it back for repairs and using insurance I had to pay for. I am without a computer to do my work. This is NOT fair.
