HP 17 Laptop PC 17-c2000 (4V792AV)

Hi

I have an HP 17-by2005nl notebook
Where is the CMOS battery located?
I think it's worn out and I'd like to replace it.

 

This is because the notebook only starts with the power supply connected, even though the battery is 100% charged (the HP test confirms this).

Furthermore, once started the day and time is that of the last switch on.

 

Without the power supply connected it won't turn on.

Thank you

You're very welcome.

 

I am not a PC repair tech by trade or training, so I would not know what to do.

 

If the notebook was not under warranty, I would probably be buying a new battery to see if that resolves the problem.

 

Presumably if your notebook is only 6 months old, it is covered by a HP warranty.

 

I recommend you submit a support case under the warranty starting at the link below.

Yes, the same info would apply for the 17-cn2005nl

Hi:

 

Your notebook does not have a CMOS/RTC battery.

 

The main battery also serves as the CMOS/RTC battery which maintains the BIOS and system clock settings.

 

Below is the link to the service manual:

 

c08119882.pdf (hp.com)

 

Chapter 3 has no CMOS/RTC battery part number.

 

Chapter 6 has no CMOS/RTC battery removal or replacement procedure.

Sorry.

I got the wrong code for my laptop, the right one is 17-cn2005nl.
But I guess this one also doesn't have cmos battery.


So what should I do to solve my problem?
The notebook is only 6 months old and the HP diagnostics tell me that the battery works correctly and has no problems.

 

Thank you
