Solved!

Help! Firmware update = dead laptop! Flashing caps lock (2 flashes).

HP Envy (E7A75EA)
Microsoft Windows 10 (64-bit)

Hi All,

 

I've just updated the firmware on my 2014 Envy (device code E7A75EA) to 'F.68 Rev.A' from HP Support and now it will not boot!  Instead all I get is a blank screen and the caps-lock flashing twice (which I'm told means corrupt BIOS!)

 

I followed the instructions carefully and no error message appeared in Windows, but when the laptop restarted it failed to load Windows and just gets stuck on this blank screen.  I've tried removing power cord/battery, and then holding down the power button for 1 minute but this hasn't helped.

 

Can I boot to USB/CD and flash back the old firmware (v43 I think)?

 

Please help!

Anyone?  This is totally unacceptable, my laptop is completely useless now!!

 

I've tried creating a BIOS boot USB device (http://support.hp.com/gb-en/document/c00042629) but the laptop will not boot from the USB, nothing happens!

 

Thanks,

M.

It's alive!!

 

I removed the CMOS battery, powered up the laptop (it booted into Windows), shutdown, reattached the CMOS battery and it continues to boot correctly.
