Hello! I'm new around these parts, but if anyone can offer any help with my strange problem, that would be super appreciated! It's been incredibly difficult for me to troubleshoot this one by myself.
I picked up this laptop last December, and while I've been pretty busy since then, I've come across two weird problems in that time, that I'm now trying to figure out.
1st: Backlighting on laptop keyboard. It has four power settings (controlled with function and up/down arrow keys). When the keyboard backlights are turned off, or on the lowest power setting, the laptop makes a strange high pitched buzz. It makes no noise when on the two higher light settings.
2nd: Laptop stutters severely when running games on higher graphics settings. Now I know this isn't a power house laptop, but it should at least be better than my older ROG laptop that had a 770M. Basically, it'll run fine at first, smooth, then after a while, it'll start a cycle of stuttering. It'll basically freeze up for a moment, 1-2 seconds, then return to normal, and repeat repeat repeat. Timing is dependent on graphics settings, higher increasing the timing. Here's a quick rundown of some games I've tested this with:
- The Division 2: Unstable with any settings
- World of Tanks: Stable at medium settings
- Wars: The Old Republic: Stable at medium settings
- Starcraft II: Stable at medium settings
Something is definitely wrong here - even my old laptop could run Division 2 stable with the lowest settings. Further, I recently discovered that, with world of tanks, the problem disappears while the laptop is unplugged. Plugged in it will run like a potato at the best graphics settings, but unplugged it has no trouble with the best graphics settings. Incredibly strange!
So far I've mostly ignored the keyboard - I saw some other laptops had that problem, and apparently that's something LED's do when adjustable. Here's the troubleshooting I've tried with the graphics problem:
- Clean install of latest Nvidia Graphics drivers
- Confirmed I had most recent updates of Windows 10
- Confirmed I had the latest BIOS version, and reset to default settings.
- Checked power plan settings for plugged in versus battery. Tried changing plugged in to match battery, but no change. Reverted.
- Checked Nvidia control panel for power options - tried changing graphics card 'power management mode' to 'prefer maximum performance'. Some improvement, but not a fix at all. Reverted back to 'optimal power'.
I'm pulling my hair out on this, and I'm getting close to going to Asus support and sending it in for them to look at / replace. At first I thought that maybe there was something up with the auto overclocking Asus has done with this laptop - I've never really messed with overclocking - but I used Armourycrate to monitor the GPU temp for how hot the card is when the stutter happens. It seems to always happen at 77 degrees, even with full fans running. Online I've read that the 1660ti is safe up to 90 degrees, so I don't know. And then world of tanks running better on battery just makes no sense to me.
Anyone have any ideas? Please help!
Laptop specs: (GU502DU)
AMD Ryzen 7-3750H (Has an integrated GPU, not sure if that's related)
Nvidia GTX 1660 ti (Driver version: 442.50)

(I've added a second 8 GB stick of ram, so 16gb total, and a second 512gb ssd. I matched the ram as best I could, however the included one cannot be removed, so I couldn't pair them properly. Everything above has been happening before and after I added these parts)
