BIOS update failure

[campyrs52]

Today I went to the page for my Envy to get updated drivers for the network.  While there, I saw a bios update dated 8-3-16  (today)   and went ahead and installed it.  It said in a box that it had to restart my laptop and that was the last time my laptop worked.  I now have a black screen and the cap lock key flashes twice and then pauses and then flashes twice.  Over and over.

The system doesn't recognize HD, DVD nor USB drives.

Is there anyway to bring this system back?

Hi @campyrs52, 

Welcome to the HP Forums! 

I understand that you are getting a black screen when trying to turn on your HP Envy 17" Touchscreen Notebook. I am happy to look into this for you!

First I would recommend to try Recovering the BIOS, and then if that does not work, try the steps in this guide, Computer Does Not Start (Windows 10).

Hope this post helps! 🙂

Thank you for your response.  After hours of frantic searching, I found directions on how to make a BIOS repair external drive.  I made a thumb drive using that method, held the windows key and the B key down and prayed to every Diety I could think of.  After 9 hours of a black screen with the cap lock flashing 2 on, pause, 2 again.  Over and over.  The thumb drive began flashing and the screen started flashing and a cmos-type screen appeared and repaired the BIOS. 

The laptop is up and running again.  I have to tell you I probably will never trust a BIOS update again after this fiasco.  I trusted HP, that the drivers they posted for my device were good.  I learned a valuable lesson.  If it ain't broke, don't fix it.  

Thanks again
