ASUS R552JV - where is the cmos battery?

[fghoward1]

I have a black screen with no sign of life. Troubleshooting this has resulted in a complete teardown of the laptop. No obvious signs of the cause. It won't produce a live screen when I attach another monitor via the HDMI, so I assume my laptop screen is not the problem. Removed the CPU and GPU unit and cleaned and applied new thermal paste. I'm in Sydney and we've had weeks of hot weather, the inside of my house not going under 30C, day or night. Today reached 41.8 C outside and we've had many days over 100f in the old terms. However, rarely use this laptop. Reassembly went OK, but the problem isn't fixed, so I assume the MB is stuffed. Can't find a replacement anywhere on line.
Long way to get to my question , but where is the CMOS battery ? I've literally stripped this to its smallest components, and there was no CMOS. Anybody know the answer and if it fails can it cause my black screen problem.
Thank You

and then there is the same as a PC motherboard -

I can find any decent pictures of the board online so you'll have to upload some images.

Thanks for the feedback Steven. Didn't know that they have switched to a capacitor. If that's the answer, it will have to be one soldered directly to the MB as I saw no capacitors hanging off wired socket. Looks like I'll have to strip it again and look for a bulging capacitor

Many thanks Steven. Found it first go as soon as I took the back off. Hidden under black tape. Tried to post jpgs but I'm new to how to do this. Can't see that they uploaded, so trying again here. Apologies to all if this isn't how you do it.
