BIOS for the HP ProBook 445 G1, board 12240-1 on the Python 14 platform, with PCB marking 48.4ZC05.011, in a 2.88 MB RAR. The 12240-1 and 48.4xxxx numbering follow Wistron board conventions, and the 48.4 code is printed on the PCB for identification. Flash the image to the SPI chip with a programmer to recover a laptop that powers but shows no picture or loops at startup. Check the board number on your unit matches, back up the existing chip, and make sure the image size fits the flash capacity.
