Hi Atom,
A small update. I installed the recommended ssd drive over the weekend and got another 512GB. Installation was very easy and went without an issue. I then proceeded to do a clean win10 pro installation. After installing all the drivers from the aorus site plus apps and doing all the updates with drivers update the system gauge worked again and everything so far seems to be going smoothly. I ll be connecting an external Bluetooth keyboard and mouse tomorrow. I then reinstalled assassin's creed syndicate and diablo 3 and unfortunately I have the same issue. On power supply all the games work perfectly well with great graphics and high frame rates (amazed at what the laptop can do with assassin's creed even at native resolution). As soon as I try to start the games on battery mode using high performance and making sure from the NVidia panel both games use the NVidia card (even though it should do it automatically) I get the problem. With Diablo 3, the game starts I move around a bit and then the computer turns off. With assassins creed as soon as I go to resume play it switches off again. I am really perplexed and troubled because other than that I have to say I am loving the laptop. Its speed is phenomenal, the screen is great, it is really quiet even under load, with moderate usage I am getting 6-7 hours of battery and there are plenty of tweaks I found that will probably reduce it more. But this problem is really nagging me. Have you heard anything from HQ? I am going away at the end of the week and if this is something that cannot be fixed and the machine needs to be replaced then I would like to do it as quickly as possible as I was planning on working over the break and my old laptop is dead. Your input would be greatly appreciated. Many thanks
Maybe try installing steam OS if it has those games for steam? It may be a windows problem?
