CMOS error - CMOS battery dead?

[Larron77]

Hi,

About a month ago, I changed the battery of my laptop (it lasted 4 years). Not sure if this is related, but today, when I unplugged the AC cable, the laptop just turned off, and didn't really want to restart for a while. When it finally did (plugged in), it said there was a CMOS error. So I started reading about it, and people were saying that it was probably a dead CMOS battery. Well, I opened the laptop, but I couldn't find it anywhere. I've attached photos of the inside of the laptop (HP Pavilion Gaming 17-cd0005nq). Can you give me any advice as to where I can find that battery?

Edit: I've also noticed that the SSD has started heating up, which is unusual. Can these things be related to a failing power supply unit? We've been having power fluctuations in our apartment for the past couple of months. We use surge protectors but still, can power fluctuations cause something like this?

Thanks in advance!

Hi:

Your notebook does not have a CMOS battery.

The main internal battery maintains the BIOS and system clock settings.

You will probably have to install a new main battery if you continue to get the CMOS error.

Below is the link to the service manual:

Maintenance and Service Guide HP Pavilion Gaming 17 Laptop PC

You will see in chapter 3 that there is no CMOS battery part number and no CMOS battery removal and replacement procedure in chapter 5 or 6.

I can't answer your question as to why the SSD is heating up.

They normally tend to run hot.

Your notebook's SSD is encased in a thermal enclosure and there should be a thermal pad under the metal cover.
