Battery change laptop

[sualdea]

Hi, I have noticed that my laptop battery no longer lasts as long as it used to, and I have run the battery check and need to replace it, but I can't find the battery model so I can buy another one and replace it, although I do have the serial number. Where can I see the model of my battery?

HP has produced and brought to market more than a thousand different models of notebooks and desktop PCs over the years.



It is difficult to help you if we don't know the hardware configuration of the laptop that you own.

Method #1: If the notebook will boot into Windows, you can retrieve your Product Number by pressing Fn + Esc key.

Method #2: Press the power button and immediately tap the F10 key to invoke the BIOS. In the Main section, you will find the Product number or Product ID. Post that in your next reply in your thread.

Method #3: Press the power button and immediately tap the F2 key.

Method #4: If powering on is not an option, take a look at the bottom of the laptop for the label with the product name and product number. For a desktop look at the rear for the label.

If your laptop has HP Hardware Diagnostics UEFI version 10.3.0.0, there is a System Information section that also has the Product ID.
We need that information, along with the installed Operating System information to help you.

Thanks Erico, here is the information u asked for, the product ID and the Operating System info. I found it in the HP Hardware Diagnostics.

Product id: 2T666EA#ABE

Operating system information: Windows 11, version 23H2 (10.0.22631)

It is highly recommended to purchase and install only Genuine HP part numbered batteries. "Compatible" batteries have been known to not always operate as expected. That is what you are experiencing since you used the generic part number to source a replacement battery.

My online search using Google.es

Note: the AliExpress ad is extremely unlikely to actually be for a genuine HP battery!

For future reference, using the official HP PartSurfer web document with the serial number as the keyword is the best way to find part numbers for your specific laptop.

But one question, on the Maintenance & Service guide it says it is for the Model numbers: 15-dy0xxx, 15t-dy000 and mine is 15s-fq1090ns. Is there any problem with that?

[erico]

Your laptop is in the HP 15 Laptop model series, so that is not a problem.

You can also use the serial number in the HP PartSurfer web document to find the battery part number.

Input the serial number of the laptop and press enter. All of the parts listed are specifically for your laptop.

I looked at the hp part sufer with my serial number, and the battery is L11421-546 instead of the one u told me. Is it the same or it just doesnt matter?

[erico]

The part number in the PartSurfer is also compatible.

It is a superceded part number not available when the Maintenance & Service guide was written and published.
