Lenovo BIOS firmware archive for the ThinkPad Yoga 11e 4th Gen laptop, machine type 20HS, packed as a 4.86 MB RAR. A technician uses such a dump to restore a corrupted or locked flash chip on this education-series convertible. Program it with a SPI programmer such as a CH341A or similar after saving the original contents, which carry serial and system data. Confirm the machine type on the label matches 20HS, and verify the extracted image size equals the flash chip capacity before writing.
