Firmware for an HP laptop with model code TPN-C129 on the CSL50/CSL52 platform, board LA-E811P, dated 18 July 2017 in the name, where the revision field is incomplete. The LA-xxxxP format is Compal's board numbering, identifying Compal as the ODM. The 3.76 MB RAR is intended for reprogramming the SPI flash with a CH341A or similar tool when the notebook will not start after a firmware fault. Back up the existing chip, which stores unit identity data, and check the revision printed beside the board number.
