I'm halfway through disassembling a Toshiba Satellite PA3817U-1BRS, where is the CMOS battery located?

I briefed a tutorial on how to disassemble my laptop, but I don't know if it applies to my model. So I need to know if the battery is below the keyboard or the bottom of the laptop.

P.S. I noticed a couple of screw on the motherboard that may have caused the laptop back to not come off because I removed every screw except one. So I assume it's beneath the motherboard.
So where is it?

Hi, if you don't see the battery on the top, it should be underneath.

This computer has never been fiddled with ever by anyone. I dont see a battery or battery slot on the top or bottom. I even looked under the CPU

can you please tell me what it looks like or a picture in this post. I'm usually familiar and aware of what a battery looks like, but I dont see it anywhere. I bought a Ultralast 2032 from Micro Center and asked them what type of battery I needed. So why am I not able to locate or see it

What is the model of your laptop, the number you wrote is the battery's number.

It's a Satellite P755-S5215

The RTC battery is on the CPU side.
