RAM: Original/New not being detected!

So, last night I tried to install a 4GB RAM (Let me know if you need RAM specific model, brand was Adata), but it would not be detected by my new laptop. I placed the 4GB back into the old one to see if maybe I had mishandled the stick and defected it, but old PC detected without a problem. Then, I tried to install the original one back and it's showing that I still only had 4GB of RAM (I'm assuming the second slot is behind the keyboard, and I'm very reluctant at the moment, to do it myself. Is it possibly a faulty slot?
When I took the original out, it popped up when I removed the clips, but I had to also wiggle it out. And upon placing back in, i had to wiggle it also. However now, no wiggle is needed and it DOES click in, but unlike the one in my old PC. By all
appearances the slot does not seemed to be damaged, and I've tried to reinstall several times. I've read several articles from this site, and others, and nothing. Any ideas? Advice? Do i need to take it for repair?

New PC has a Intel i5 5200u.

Hey Fallenx616x. The first thing to check is to look in the BIOS and check that the timings are set correctly (you can find the correct timings on the box or the page on AData's website, let me know if you're unsure).

Harryfishrules - First and foremost, thank you for your reply, while I am new to PC upgrading, I have always been rather tech savvy. As i understand UEFI Firmware Settings replaced BIOS, and upon entering I don't see anything that would resemble timing. The only thing i see related to RAM is the "Main" tab that tells me how much is installed1 -

Tradesman1 - Other than the DDR3 labels, how would I determine compatibility?

If trying to mix DRAM it's pretty much a 50/50 crapshoot, the only way to run mutiple sticks is if they all come tfrom the same package, that way you know they are tested to play nice. On laptops in particular if only a single stick best to get one from the manufacturers list. As far as the timings, many laptops don't even display them in the BIOS as most laptops have a locked BIOS so you can't do things like OC or change DRAM setings - you might damage something and also they want you to buy all upgrades from them - often at extremely high prices

My whole problem is, it was originally running on two sticks. I bought the PC as a 6GB, there's another slot that MUST be running a 4GB behind the keyboard, because the RAM I removed is a 2GB Kingston. It didn't detect the 4GB ADATA, otherwise it would be an 8GB. But when I attach the 2GB Kingston that I took out, it's still showing 4GB. That's why I was wondering whether I must have defected the slot when I removed the cartridge the very first time. It was very stiff, and with a little wiggle it came out. Nothing appears damaged in the slot, I checked multiple times. There's a difference in the fitting of the cards however. The 2GB Kingston can wiggle a little if I push it down on it, while the 4GB ADATA seems to fit snug, no wiggle.
