Pavilion 14-ce1006ng does not boot after battery replacement

[Läppy69]

Hi all. 
I had to replace the laptop battery and used a fully compatible GREENCELL modell. After replacement, the system does not boot anymore. CAPS-LOCK shows blinking error code:  5x long + 4x short.  Cannot enter any system menu, i.e. ESC or FN keys have no effect. The only way, the system boots correctly is after I do a manual (WIN+V) CMOS reset. But, when restarting or shutting down and turning on again, same bad situation - stuck boot process and blinking CAPS-LOCK. Tried w/o any battery and power supply but same issue. Spent 2 times 1-2h with HP chat support but ended with 'Buy always original HP products / Cannot help you'. I doubt, that this is suddenly a hardware issue. HP Diagnostics Programm (WIN, not UEFI) shows no errors other than a no possible system check on battery (expected as I had it uninstalled). Any help is much much appreciated.

@Läppy69, Welcome to the HP Support Community!  

Thanks for reaching out about your query regarding your HP Pavilion 14-ce1006ng Boot Issue After Battery Replacement! 

We're thrilled to have the opportunity to assist you and provide a solution.  

It appears that your HP Pavilion 14-ce1006ng is experiencing boot issues after replacing the battery. The CAPS LOCK blinking error code indicates a hardware problem. According to the diagnostic codes:

Blinking error code: 5 long + 4 short blinks

The error you're encountering (5 long red blinks and 4 short white blinks) signifies a graphics initialization issue, specifically "Graphics adaptor not found" or a related fault.

Here are some steps you can take to troubleshoot and resolve this issue:

Steps to Troubleshoot and Resolve the Issue:

Hard Reset:

• Disconnect all external devices and peripherals.
• Unplug the AC adapter.
• Remove the battery (if removable).
• Press and hold the power button for at least 15 seconds to drain residual power.
• Reconnect the battery and plug the AC adapter back in, then try to power on the laptop.

Reseat Graphics Card (if applicable):

• If your model has a discrete graphics card, try reseating or replacing it. However, many modern laptops have integrated graphics built into the motherboard, making this step not applicable.

Verify Connections:

• Ensure that all internal components are properly seated. This includes memory modules and display connectors.

Clear CMOS:

• You have already performed a manual CMOS reset (WIN + V), but you might need to clear the CMOS properly.
• Disconnect the battery and AC adapter again. Remove the CMOS battery from the motherboard and wait for a few minutes before reinstalling it.

Hope this helps!  

Take care, and have an amazing day!

Hello, thx for your reply! Hardware reset didn't help. Graphic chip is integrated. All components properly connected. So....want to check/replace the Cmos battery, as you suggested.  But: Are you sure this laptop model has a distinct battery cell at all?? Reading, that many laptops don't have a separate battery. Pls verify your suggestion. In case there IS a battery, where is it? Cannot see one and want yo avoid disassembling the motherboard if there is not battery at all/backside. Thank you.
