My laptop has been throwing a wobble, its after an Avast download (thanks Microsoft) .Taken 2 days before it runs smooth, 2 reboots as well. Now the battery is playing up as it turned off while I was watching a You Tube last night. I thought it was just a flat battery but it should tell me to turn on charger, when I did I checked and after 1min it said 36% so I dont think it did go flat hence no warning. Very strange.
