Archive for the HP EliteBook 840 G6 described as an endpoint security fix, 10.6 MB RAR. HP business laptops can halt with an endpoint security or Sure Start message when firmware or protection data is damaged, and such packages usually contain a corrected BIOS image for flashing with a programmer. The exact contents are not stated, so extract and review them first. Read and back up the original SPI chip, since it holds serial and product data, and confirm the image size matches the flash.
