Product: HP ENVY X360 - 13-ar0104nc
Operating System: Linux

Dear HP community,

I replaced the battery of my HP ENVY X360 - 13-ar0104nc laptop.

After the replacement the laptop does turn on, however it does not boot. I was presented with the following screen.

 

SCREEN 1:
The CMOS checksum is invalid. The CMOS will be reset to the default configuration and will be rebooted. Please check your BIOS setup options to see if they change.
CMOS reset (502)
Enter - reboot the system
For more information please visit "some link"

 

After pressing enter Screen 2 is displayed.

 

SCREEN 2:
Selected boot image did not authenticate. Press enter to continue.

 

After pressing enter the computer turns itself off - the screen goes black and the fan stops.

 

I suspect this is secure boot issue, since I am on Linux and not the original windows 10. However I was not able to enter BIOS (by spamming F10 after start up) to disable secure boot.

 

I tried to restart the computer couple times. I always got screen 2. I am able to get screen 1 again, if I unplug the battery for at least 60 seconds.

 

How can I resolve the issue? Thank you very much in advance.
