I have a Lenovo Legion 5 15ACH6H with an RTX 3060 that is soldered to the motherboard and appears to have died. The laptop still powers on and plays Windows startup sounds, so I'm wondering whether the CPU and integrated Radeon graphics are still working. I had been using a performance mode that forced the system to use the RTX 3060. Is there a way to switch the laptop back to the integrated GPU, perhaps through BIOS or with an external Windows 11 PC, so I can use it for college instead of borrowing another laptop? I've already tried navigating the BIOS blindly for about an hour without success.

The integrated GPU may still be functional, but you can only use it if the laptop’s firmware and display wiring allow it. Disconnecting or disabling the dedicated GPU is not normally something Windows can do when the machine cannot display an image, and blindly changing BIOS settings is risky. Try resetting the BIOS to its defaults, then test both the internal panel and an external monitor. If neither shows an image, the failed GPU may be preventing initialization, and this model may not be able to operate normally from the iGPU alone.
Because the RTX 3060 is soldered to the motherboard, a failure in the GPU or its power circuitry generally means the motherboard needs board-level repair. Whether the integrated graphics can work separately depends on how the laptop’s display outputs are wired. On many gaming laptops, the internal screen is routed through the dedicated GPU unless hybrid graphics is enabled, so simply selecting the iGPU may not restore the display. Try connecting an external monitor, performing a BIOS/EC reset, and checking whether the laptop appears on the network or can boot into Windows. If it remains unusable, a motherboard replacement or specialist repair is usually the practical solution.
I’m not trying to repair the RTX 3060 itself. I’m hoping to disable it and make the laptop use the integrated graphics instead, if the CPU and motherboard still support that.
