BIOS firmware archive for the Lenovo IdeaPad S510p, with the name referencing the LS41P board and the numbers 48.4L and 106.011, which look like a PCB part code and a revision marking. The RAR packs about 3.34 MB, consistent with a single SPI flash image plus perhaps a readme. Technicians use such a dump to reprogram the BIOS chip with a hardware programmer after a corrupted update. Compare the codes printed on your PCB with those in the name, and read and save the original chip contents before writing anything.

How to open a .rar file
Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
