cmos error for HP laptop

[Maximus_IT]

I have a HP laptop. My laptop model number is HP-17 CA1003DS. I recently changed the internal battery of my laptop. I followed the information on my old battery to use a spare HT03XL L11119-855 battery. I bought it from Amazon. After I put it in my laptop I charged it and when I first turned it on after replacing the battery a coms error showed up. I pressed enter and it restarted normally. My bios has been updated in the past. I am currently running Windows 11 which I downloaded from Microsoft after I changed my battery. I don't have a warranty with HP for this laptop. I am also a one year college student. I was studying to be a IT. Can someone please help me figure out the issue? Thank you in advanced.

Does your college have a "Computer Help Desk" that provides free technical support to you, as a student?

What is the issue? Does it display that error-message 100% of the time after you power-on the computer?

No it does not show up all the time. I have seen it twice since I changed my battery. I am not currently in college right now. Other than the two times it has showed when booting up it normally boots up showing the HP logo with the white dots showing that it is loading up. Next time it shows the error message I will try to take a picture with my phone. The error is a cmos error.

@Maximus_IT --  The error is a CMOS error

The motherboard has a small battery, about the size of a USA $0.25 coin.

It is not the large battery that connects to the bottom/back of the exterior of your laptop.

This battery is intended to provide a "trickle" of power to the CMOS, even when the laptop is totally powered-off.  

In your case, that CMOS battery has failed, and must be replaced. The battery is $1 or $2.

The longer that the laptop is totally powered-off, the more-likely that the residual "charge" in the CMOS battery will be insufficient to avoid that "CMOS Error" message. Expressed differently, if you power-off the laptop, and then within a few hours, power-on the laptop, you will not see the error-message.  But, if the computer is powered-off for a day or two, the next start-up will show the error-message.

Sample replacement battery: 

If you are not comfortable with disassembling your laptop, to remove the dead battery, and to purchase and install a replacement battery, I recommend that you take your laptop, and its power-cord, to a computer technician, to do the work. Yes, $40 to $60 to replace a $2 part.

 I am not currently in college right now

Does that "Computer Help Desk" ask for your student ID, to prove that you are a "current" student?

If you previously were a student, and you will be a student in the next semester, will they help you?
