Laptop will not boot after BIOS update and unit does not have a CMOS battery to reset.

[rdj6107]

HP Notebook - 14-dk0002dx will not boot after BIOS update.  Like others, it is out of warranty.  Unit was working fine before update.   I can't find a CMOS batter to try resetting the BIOS.  As I mentioned, unit was working fine prior to update.  So I feel pretty safe in ruling out memory or SSD, unless BIOS update fried 1 of the 2 or both.  I have tried the win key + B + pwr with not luck.  Is there anything else to try &/or key combination?  Sadly Best Buy had some units on sale but I am hard pressed to give HP any $$$ when I feel like the problem was their fault.  Which means a replacement unit will have to another brand.

It's unfortunate to hear about the issues you're facing with your HP Notebook after a BIOS update. Here are some additional steps you can try:

1. Hard Reset:

   • Disconnect all external devices and the power adapter.
   • Hold down the power button for about 15 seconds to perform a hard reset.
   • Reconnect the power adapter and try turning on the laptop.

2. BIOS Recovery (Phoenix Method):

   • Check if your laptop supports Phoenix BIOS recovery. This often involves creating a bootable USB drive with the BIOS file and holding specific keys during startup. Refer to your laptop's user manual or HP's support documentation for details.

3. Contact HP Support:

   • Reach out to HP Support for assistance. They may have specific procedures for your laptop model to recover from a failed BIOS update.
   • HP might provide recovery tools or steps to restore the BIOS.

4. Recovery Drive:

   • If you have a Windows recovery drive or installation media, you might be able to access repair options. Boot from the USB/DVD, select your language preferences, and choose the "Repair your computer" option.

5. USB Flash Drive with BIOS:

   • If you have access to another computer, try creating a bootable USB flash drive with the correct BIOS version for your laptop. Some systems allow BIOS recovery from a USB drive.

6. Recovery Environment:

   • Boot into the Windows Recovery Environment (WinRE) by holding down the Shift key while selecting Restart from the power options menu. From there, you might have access to troubleshooting and repair options.

7. HP PC Hardware Diagnostics:

   • If your laptop has the HP PC Hardware Diagnostics tool, you might be able to run diagnostics to identify and fix hardware issues.

If all else fails, and you're confident that the issue is related to the BIOS update, reaching out to HP Support or checking online forums for similar issues with your specific laptop model might provide additional insights or solutions. Keep in mind that any attempt to recover the BIOS should be done cautiously, following the manufacturer's guidelines to avoid further complications.

Since your laptop is out of warranty, if you decide to try any advanced recovery methods, proceed with caution, and consider seeking assistance from knowledgeable individuals or HP Support forums. If the problem persists, you may need to consult with a professional technician or consider alternative brands for your next purchase.
