I have an Acer Nitro 5 model an515_55 with a GTX1650 and an Intel i5 10300H, lately, I've been having an issue with my discrete GPU not being found, whenever my GPU is missing a device called Intel PCIe controller x16 - 1901 pops up with a code 10, an ACPI power object failed to transition state. I have looked for newer drivers for this device and cannot find them. Device manager says that the currently installed version(10.1.7.3) is dated 7/18/1968. Is this just a bug and are the newer drivers or is this just a hardware issue and something inside my laptop went bad and no longer functions?

Regarding the odd date stamp, review this article:

The actual issue has already been discussed, without solution though:

Looks like an Acer specific issue...
