Compressed firmware package for a laptop identified as L510, tied to board 6050A2250501-MB-A03, so revision A03 of that motherboard. The 6050Axxxxxxx numbering is the Inventec style found on many PCBs, and the trailing MB-A03 marks the main board revision. At 792 KB the archive likely holds a small image of about 1 MB, which suits a 1 MB (8 Mbit) SPI chip. Confirm the number printed on the PCB, dump the existing chip with a programmer as a backup, and compare sizes before writing anything.
