Battery replacement issue

[Susrex]

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.

Hi  @Susrex,
 
Welcome to the HP Support Community!

Thank you for reaching out.

 I understand that after replacing the battery in your HP ENVY x360, the notebook powers on but displays a CMOS Reset (502) message followed by "Selected boot image did not authenticate". I can certainly understand the concern and I'll be glad to help you . 

To better understand the situation, could you kindly confirm the below details:

• Was the replacement battery an HP original battery or a compatible third-party battery?
• Before replacing the battery, was the Linux installation booting normally without any Secure Boot or startup-related messages?
• When powering on the notebook, have you tried tapping Esc repeatedly immediately after pressing the power button to access the Startup Menu?
• Are you able to access any of the Startup Menu options such as F2 System Diagnostics, F10 BIOS Setup, or F9 Boot Options?

In the meantime, kindly try the below steps and confirm : 

 1: Perform a CMOS Reset (Click here for steps )

1. Turn off the notebook.
2. Disconnect the AC adapter.
3. Press and hold the Power button for 15-20 seconds.
4. Reconnect the AC adapter and turn the system on.

 2: Attempt to Access the Startup Menu

1. Turn the notebook off.
2. Turn it back on and immediately tap the Esc key repeatedly.
3. If the Startup Menu appears: 

• Press F10 for BIOS Setup.
• Load BIOS defaults (usually by pressing F9).
• Save changes and exit (usually F10).

 3: Run Hardware Diagnostics (Click here for steps )

If you can access the Startup Menu:

1. Press F2 for System Diagnostics.
2. Run: 
   • Battery Test
   • System Board Test
   • Memory Test

 4: Check Secure Boot Settings

If you are able to enter BIOS Setup:

1. Navigate to Security -Secure Boot Configuration.
2. Note the current Secure Boot status.
3. Let us know whether Secure Boot is enabled or disabled before making changes.

Once you share the requested details and let us know whether you can access the Esc Startup Menu, BIOS (F10), or Diagnostics (F2), we'll be happy to guide you with the next steps.

I hope this helps.

I was able to access the start up menu by tapping Esc repeatedly during powering on the notebook.

From there I get to BIOS and changed the required settings, notably disabling secure boot. This has resolved the issue. The laptop boots normally now.

Thank you for your help!
