After installing Windows 10 64-bit (clean install), updates and all, I tested that everything worked right and it actually performed quite well! So I decided to update the BIOS to the latest version (F.34) from the previous version F.32 (note: nothing was plugged in aside from the AC cord). At the end of the process, the screen went completely blank but I remembered that the Restart button was highlighted, so I pressed Enter and the computer restarted.
When the computer restarts,the LED lights work and the fan spins but that's all. I have performed a hard reset (several times actually), tried holding down Windows+B, connected it to an external display (no image on it either), I've looked into recovery options such as WINCRIS (in XP SP3 compatibility mode) but I'm unable to use it since I can't select the files required, the Browse button is greyed-out, and I even removed the RAM modules and put them back in.
The only help I could find was the BIOS recovery help page http://support.hp.com/us-en/document/c02693833, but the BIOS executable for my computer doesn't offer an option to make a recovery disk, so I'm completely stuck.
Either I missed a step or I'm doing something wrong. It really sucks that the BIOS update from the maker of the computer would render it useless...
Any help would be appreciated!
I decided to give the WINCRIS BIOS flash method another try, where you create a USB flash drive with the BIOS file on it, remove the battery, disconnect the power cable, hold down the Windows+B keys, plug in the power cable, press the power button, wait three seconds and release the keys. The problem is the BIOS files contain two different usable .WPH documents (one A and one B). I tried with the A, renamed it BIOS.WPH and now I get 1 long + 2 short beeps. That's the furthest I've been able to get to yet.

Welcome to the HP Forums!
I have read your post and understand that your HP Pavilion dv9620us is not booting after attempting a BIOS update. I have researched the issue and have come up with a possible resolution. First, please perform a hard reset. Once that is complete, please follow the steps in these documents:
If the documents do not help you resolve the issue, try restoring the BIOS again.
Thank you, I look forward to your response with the outcome.

Thank you kindly for replying to my message.
I have consulted both articles, unfortunately to no avail. Also, the BIOS executable for this model does not offer a way to creat a BIOS restoration USB key, like the way it's mentioned in the third document.
Are there any other options available?
