Battery replacement

[MissusMalarkey]

Help!

I need a new battery for my HP laptop (14-cm0xxx) but don't know the part number (I don't want to take the existing battery out before I've got a replacement).

I've spent a couple of hours googling, looking on Amazon, Ebay etc, but don't want to buy the wrong thing. Is anyone able to let me know the part number that I need to buy please?

I'm based in the UK,

Thanks in advance,

Hello @MissusMalarkey 

Before replacing the battery, you should do the following ...

(1) Create Windows system <restore point>

How to Create a System Restore Point on Windows 10 or Windows 11

(2) Download and install BIOS Update 

HP Notebook System BIOS Update

Why should you install the update ?

Updating the BIOS is recommended as standard maintenance of the computer. It can also help resolve the following issues:

• An available BIOS update resolves a specific issue or improves computer performance.
• The current BIOS does not support a hardware component or a Windows upgrade.
• HP Support recommends installing a specific BIOS update.

"

(3) Reboot

(4) Let BIOS be installed until it's completely done !

(5) Please report your results

Good luck

So I've got a new battery and created a system restore point etc.

However the updated bios means that I can no longer get into my laptop.  I can't reset a pin or password, can't get in as an administrator,  and can't use the system restore point.

Hello @MissusMalarkey 

The Bios update only updates the "Bios" program code and certain areas of the Bios data block, it does not change any user accounts/passwords or Windows accounts/settings (on the hard drive), don't worry.

Kind regards

But the change has meant that Windows tells me my PIN is no longer available. I have no way of getting in to my laptop so I don't know what to do.

I have spent hours today looking for a solution but haven't found one so I will need your help please.
