The Lenovo G505s is a 15.6" laptop using AMD's fam15h Richland APUs. Part of Lenovo's low-cost "Essential" laptop line, it is commonly misidentified as part of the separate IdeaPad product line. The G505s has historically been a well-known laptop option among Qubes OS users, as historically most older 100%-FOSS-firmware laptops (such as the ThinkPad T400) have not supported an IOMMU, required for Qubes as of 4.0.
Open Source Firmware
This laptop is not currently supported in coreboot-15h. However, it was supported in upstream coreboot until recently. Instructions for building its firmware can be found on Mike Banon's webpage.
Flashing Firmware
To switch from the stock firmware to coreboot, external flashing is required.
