BIOS archive for the HP Compaq CQ45-702TU, with the motherboard number 6050A2493101-MB-A02, meaning revision A02. The 6050A numbering belongs to Inventec, the ODM that built this board for HP. The 3.13 MB rar provides the flash image for reprogramming the BIOS chip when the laptop shows no display or loops on power. Check that the 6050A number and revision on the PCB match, and back up the original chip contents before programming.
