My 2 month old G14 has had appalling battery life recently and I can't seem to diagnose the problem on my own. As recently as yesterday my battery life was reaching well into the 11 hour range with the dGPU disabled and the screen set to 50% brightness and 60hz. However, out of nowhere, my laptop got down to 20% battery after two hours of light usage today. I'm talking "only a few tabs of Chrome and OneNote at 5% CPU utilization" level light usage.
I checked the ASUS Armoury Crate and my settings were just as I left them (Optimized profile, so dGPU is completely shut off when on battery and turned back on when plugged in). Checking Task Manager, the iGPU was the only detected graphics card, which is to be expected when the dGPU is shut off. I got one notification saying my graphics driver crashed or didn't load so it was booted into safe mode. Another said my graphics driver wasn't loading or wasn't detected and asked if it could send diagnostic data to AMD to collect data on the problem.
My working theory is that my dGPU is draining my battery despite being disabled in software and undetected in Task Manager. But I have no way of diagnosing this on my own. I tried reinstalling my GPU drivers and the Adrenalin software altogether, but no dice. I'm still losing a percent of battery life every minute and a half or so, even with the dGPU disabled. Can one of you fine folks help me out? Thanks in advance.
P.S. Before you get on my butt about being a laptop gamer, I'll let you know I built my own 9700k and 2070 rig a few years ago but had to leave it at home when I left for college. Bringing a desktop on a plane simply isn't practical.
Specs if it helps:
AMD Ryzen 9 6900HS with RDNA2 integrated graphics
AMD Radeon RX 6700S
16 GB DDR5 RAM at 4800 MHz
1 TB SSD
EDIT: I'm told countless other 2022 Zephyrus G14 users are having the same issue and it's a BIOS problem. Click here to see a Reddit thread
