I really appreciate the response! But, it is stuck in a BIOS Boot Loop that I can not exit. And, apparently, there is no CMOS battery on this device.

Hi@ITguyinBama,

Do you see a light at the place where the charger connects to the laptop? If yes then it indicates that the charger is all fine.

I recommend you to perform the following steps to isolate the issue and arrive at a fix: 

• Remove the battery out. If the battery is integrated and does not have a latch to release it then leave the battery inside the laptop.
• Disconnected AC adapter from the laptop.
• Press and hold the power button for 15 seconds.
• Reconnect the battery and plug the AC adapter.

F6 + Power Button

• CMOS Rest ( combination of windows button and letter 'V' then push the power button ones and release the windows and letter 'V' after 5sec

If the laptop does not power on then please continue with the below steps:

• Disconnect the charger and remove the battery out.
• Connect only the battery and check if the laptop powers on.
• Likewise, remove the battery out (if removal battery ) and connect only the charger and check if that helps.

This did not work. The Win V nor B seem to do anything at all. It goes right back to the BIOS update screen. Here is what I see:

The system BIOS is being recovered.

Hi@ITguyinBama,

We have done the basic troubleshooting as per the document and the notebook needs to check to get to know its hardware is faulty, not a software issue.

I'd suggest you contact HP in your region regarding the service options for your computer or HP Chat Support Team.

If you are having trouble navigating through the above options, it's most likely because the device is out of warranty. If yes? please send me a private message with the region you are contacting us from. Check next to your profile Name, you should see a little blue envelope, please click on it.   

Have a great day!

Sorry, there is no envelope. Also, I have been on the phone with HP a couple of hours today and we've tried everything they know to pre-empt or interrupt the BIOS update but with no progress. And, apparently, there is no CMOS battery on the motherboard any longer. How is this? They now say I can send it in for "bench" testing with a minimum of $500. I have a feeling this Spectre line is going to have a lot of these kind of failures.....

Thank you for waiting! I understand your concern and to help you out, I have escalated your concern to HP's Support Team in your region to have it reviewed for available options (if any). 

You should be contacted within 4 business days (Excluding Holidays & Weekends). 

Response times may vary by region. 

Please send us a Private Message, if you aren't contacted within 4-5 business days.

And Feel free to post your query for any other assistance as well.

Hi,

Try update previous version of BIOS then upgrade to new: https://support.hp.com/in-en/drivers/selfservice/hp-spectre-15-ch000-x360-convertible-pc/16779588/mo...

Try update BIOS via usb Drive: https://www.hp.com/us-en/shop/tech-takes/how-to-update-bios-software

Refer section: "If Windows is not able to start:"

If issue is same, better call & connect with HP support.

Thanks & Regards
