I have tried to find information on how to replace the CMOS/RTC battery on my HP 340S G7 Notebook but with no success. Does anybody her know 1) where the battery is located 2) where I can buy a replacement?

Welcome to our peer-to-peer HP Community Forum!
It appears that your HP 340S G7 Notebook PC model series does not have an RTC (CMOS) battery. The main battery (p/n: L11119-855, HT03XL) maintains the system clock and BIOS settings.
As you'll see in the manual (see link), there is no reference to a CMOS battery whatsoever.
