May I have the specific model name? G733QR or G733QS?
Was there any update or modification before the issue happened?
And please kindly help to describe more detail or share a video of the issue.
How is the keyboard backlight not working? it is not lighting up in certain sceanario?
It is the G733QR. I have only owned the laptop for about a month. Sometimes after coming out of sleep the keyboard does not light up. So I try to restart but it gets stuck restarting. Also, sometimes the Xbox 360 controller stops working after a while. And sometimes the volume + or - buttons stop working. All the problems seem to occur after exiting sleep mode. Also, the laptop does not seem to be going to sleep when closing the lid: I have to trigger sleep with fn+f11. I already tried reinstalling Armoury Crate. What should I try next?
