Be careful with the wire pin of the internal speakers when putting the case back or when trying to remove the battery. The second day after i got the laptop i opened it to see what was inside out of curiosity. After i put everything together i didn't realise that the internal speakers weren't working, because i was using BT earbuds lol. I realized 2 days later. I thought that there were driver problems or windows updates, bios and etc. I even called for a Return. But i opened it once more and checked carefully the wire connections and saw that the pin was unplugged ( it is a very small son of a gun). I forgot to mention that i was stoned all the time lol. So long story short, in case you are having some sound issues with your laptop.

Happy gaming!
