This is a well known issue for the Dolby Theater with DOTA 2 and CSGO. No solution u just got to turn it on back. It only happen when the game start for example in dota after loading, when want choose hero u hear "all pick" dolby auto off dy. Annoying i know.. This issue has been since on my 4830tg about 3 years ago. 

same as mine, around 2 years, but heavy usage, open daily for min 8 hours at least. paid 350 for replace chip. 2 weeks time. now running back as normal.

Wow, so your laptop is gone, just like that... .. Good thing I always get extended warranty for electronics. Mine is currently being fixed for a display issue whereby the screen has image burns and also the too warm wrist rest area.

My condolences  .. I would be so sad and pissed off at the same time to lose a 3K+ laptop just like that.. Anyway, I've promised myself, this will be my last Acer laptop. Had an Acer laptop before this and its also currently disabled.. Hard drive issue. So unless they improve build quality significantly, no more.. I'll probably go with Dell or HP next time.

That's the thing about Apple laptops, despite the lackluster performance, they are well built. Wifey's got a Macbook Air that's at least 4 years old and still runs well. With a battery that easily lasts 5 - 6 hours. No Apple laptops or Desktops for me though..

can repair at all ? sell to me cheap cheap
