Seeking Location of IdeaPad 110-15IBR CMOS Battery

So, I ran a Vantage Hardware Scan, and my machine failed the RTC test, citing incorrect BIOS time, likely suggesting a bad CR2032.  However, I can't seem to find the location of the CMOS battery anywhere; I've scoured the HMM, searched on Google, and even tried to find the answer on YouTube, as I'm not willing to open this thing up until I'm well aware of how I'm 'attacking' the problem.  However, all I keep coming with are either lessons on how to replace the system battery (primary battery), or videos on how to replace the CMOS battery, but not for the 110-15IBR.  I don't usually work on laptops, and I'm not sure if the location of the CMOS battery is standardized in laptops, as it typically is on desktop motherboards which, by comparison, I'm infinitely more familiar with.  That being said, any wisdom that may shed light on this issue would be most appreciated, even if that doesn't turn out to be the issue.

Hi StrangeCrunchy1,


Welcome to the Community Forums.


In addition, the RTC battery (Real Time Clock) is on the bottom of the systemboard as shown in the image.




Here is also the hardware manual for reference on disassembly.
