If your BIOS update on the HP ProBook 455R G6 Notebook PC has failed multiple times, here are some steps to troubleshoot and resolve the issue:

11. Reset CMOS:

12. Reset the CMOS to clear any possible issues. This often involves pressing a combination of keys to drain residual power or using jumpers on the motherboard. Refer to the HP support site for detailed instructions specific to your laptop model.

13. Update Using a USB Drive:

14. If the update through Windows is not working, try updating the BIOS using a USB drive with the necessary files, following HP's detailed BIOS update instructions for bootable USBs.
