Laptop Display Is Corrupted Even in BIOS After Waking From Sleep
Asked by

I have a Lenovo Legion 5 16IAX10 with an NVIDIA GeForce RTX 5060 Laptop GPU, and it is only about six months old. After being left unattended in standard Windows Sleep Mode, the laptop woke up with severe display corruption. Roughly the left 30–40% of the internal screen shows a pixelated, vertically squashed version of the lock screen or desktop, while the remaining 60–70% is black or dark gray.
There has been no drop, impact, pressure, liquid exposure, or rough handling. Because the problem first appeared while waking from sleep, I initially suspected a graphics driver or resume issue. However, the corruption is also visible during startup and inside the BIOS, before Windows loads.
I have already tried resetting the graphics driver with Win+Ctrl+Shift+B, performing a forced shutdown by holding the power button for 10–15 seconds, and connecting an external monitor. The external display also behaved abnormally: only 640×480 and 3840×2160 were offered as resolutions, and changing the resolution produced an apparently empty desktop where opened applications did not appear correctly.
What could cause a failure like this to appear suddenly after sleep? Does the BIOS corruption and strange external-monitor behavior point to the GPU, display controller, motherboard, internal panel, or cable? Is there anything else worth trying, or should I document the issue and use the laptop's warranty?

Try one complete embedded-controller reset before sending it in: shut the laptop down, disconnect the charger, then hold the power button for roughly 30–60 seconds. Reconnect the charger and boot directly into the BIOS. If the image is still corrupted there, avoid reinstalling Windows or spending much time on driver updates, since those will not fix a fault that occurs before the operating system loads. Record photos or video of the corruption during startup and contact Lenovo under warranty.

Because the corruption appears during boot and inside the BIOS, this is very unlikely to be caused by Windows, NVIDIA drivers, or sleep settings alone. The symptoms point more toward a hardware problem involving the GPU, display controller, motherboard, or possibly the connection between them. The external-monitor behavior makes a problem limited to the internal LCD panel or cable less likely.

MellowCedar47: If the GPU or display controller is failing, would that require opening the laptop and having a technician repair it? I still do not understand what could have triggered such a sudden failure when there was no physical damage.
