My Lenovo u410 shuts down unexpectedly a few times a day. Sometimes I am watching a video when it shuts down, but it has also happen when i was not doing anything I just turned it on and I was about to use it when it just powered down by itself. I just bought this a week ago and I haven't done much to it so it can't be a virus. Any solution or suggestions?
I suggest you return it to the supplier for an exchange or repair or refund as it would be still under warranty.
If you try to fix it yourself you will void your warranty.
