Am I going to blow up my laptop with addition RAM?

Just purchased a super-light LG Gram 14" laptop with an i7-7500U and 8gb of onboard RAM. None of the RAM retailers show compatible RAM upgrades for this laptop in their wizards. The official LG info says 8gb RAM, and do not offer a 16gb model.

I opened the back and there is an empty DDR4 slot. (I noticed the core motherboard is labeled for the 15" version, which they do offer with 16gb). So what the hell -- I stuck a DDR4-2400 8gb Patriot SODIMM in the slot, and voila! -- I have 16gb of RAM. Tests show a definite increase in speed across the board. Haven't seen any real temperature problems.

Question: Can I damage this laptop by doing this? Why would LG be so silent on upgrade possibilities -- and not offer a 16gb version -- when there is clearly the capability of upgrading it. Could it be that a key marketing point with it is battery life, and 16gb may hurt that?

Also: I chose 2400 mhz b/c I had no idea what the speed of the onboard RAM is. They guy at Fry's said you can't go wrong choosing higher, because it will dumb down to the correct speed. True?

I just hope I'm not wrecking this thing in some way...
