FYI, I started typing this up myself and it sounded confusing so I had chat gpt reword it to sound better. Sorry, I have kids and I’m tired lol
Specs: Lenovo Legion Pro 7 16IRX8H (82WQ) with an i9-13900HX and RTX 4090 Laptop GPU.
Before anything something that could be relevant…
About a year ago I dropped the laptop. It wasn’t a huge drop, but the chassis has a slight bend in it. I’ve continued gaming on it heavily for the entire year without any GPU problems until now.
I’m having a really strange GPU/driver issue and I’m wondering if anyone has any insight?
The problem started when I noticed my laptop speakers weren’t working properly. While troubleshooting, I also discovered that Halo would no longer launch, giving me an error saying my GPU/driver wasn’t supported.
Here’s what I’ve found so far:
Lenovo Vantage was showing an NVIDIA graphics driver update failing to install.
NVIDIA Control Panel was missing.
In Device Manager, the RTX 4090 initially appeared, but showed: Code 45 — “Currently, this hardware device is not connected to the computer.”
I switched Lenovo Vantage from Hybrid Mode → dGPU Mode, restarted, and the problem remained.
I then uninstalled the RTX 4090 device from Device Manager and restarted.
After restarting, the RTX 4090 did not come back under Display Adapters. Only Microsoft Basic Display Adapter was showing.
I checked msinfo32 → Components → Problem Devices, and it showed nothing.
I ran:
pnputil /scan-devices
and Windows still didn’t rediscover the 4090.
I also checked the Microsoft Basic Display Adapter’s Hardware IDs and got:
PCI\VEN_10DE&DEV_2757
So Windows is apparently identifying an NVIDIA device.
I checked BIOS, and BIOS explicitly detects “NVIDIA GeForce RTX 4090 Laptop GPU.”
I also tried a full power/EC reset (shut down, unplugged, held power button for ~30 seconds), but Windows still only showed Microsoft Basic Display Adapter.
So I’m wondering:
Is this likely a Windows/driver issue, firmware issue, or could the RTX 4090/motherboard have developed a hardware problem?
The fact that BIOS sees the 4090, while Windows falls back to Microsoft Basic Display Adapter, is what really has me confused.
I’d really appreciate any suggestions for what to check next. I’d especially like to know if there’s a way to determine whether this is hardware failure before I start reinstalling Windows or paying for a motherboard repair.
