I had purchased a new ASUS laptop for about 600 dollars at a Best-Buy, in March of this year. I first started having problems with the laptop randomly shutting off about June; the tech guy said I was always charging it so the battery doesn't work. I thought "Alright" I got the battery replaced and I did not charge it until it was about 30% then one day I took it off the charger it was on because I needed it for a recipe when I unplugged it shut right off, my battery was full. It happened for about two more months before I went and got it fixed. The Geek-squad people said it was fine and such. When I got it back that battery was full, I had used it, and when I was done, I shut it off. The same day I went to turn it on it turned on till I got to my lock screen, then it went "Peew" and shut it off. Now I have to keep it plugged in or it shuts off. My main questions are: Should I sell it and purchase a different brand? Why does it shut off? Are most ASUS's pieces of junk?
