I've bought a Yoga 300-IBR to work with while I am at the university. After just 9 days of use i noticed that my laptop became a lot slower, even the simpliest tasks could cause major lags. I started looking for the source of my problem and I found out that only 2 GB of RAM were available. This laptop has 4 GB from the factory, which are just enough to run Windows 10 and to have some basic multitasking capabilities. Standard hardware-scanning software from Lenovo didn't recognize any problems except that only 1 RAM stick was still working. I'm highly concerned of the laptop's quality since I have treated it like a treasure ( no disassembling, no overheating, no moisture whatsoever, always kept clean and polished ) and I'm wondering what are my options. What should I do with it now? Try to open it up and check whether some bad quality soldering could be the issue and possibly repair it? Or should I send it in for a warranty repair which will take more time? Or should I contact the online shop, where I've bought this particular laptop? Please, give me some advices.

If you purchased it recently, I'd advise going to them first. Otherwise, go to Lenovo's warranty support: http://support.lenovo.com or 1-877-453-6686
They might also have the option of repair at a Geek Squad location (Best Buy), or on-site repair; so ask about that.

Your memory is soldered to the motherboard.
Hardware maintenance manual show NO memory slots. Similar Machine:
Could you go into task manager, performance tab and see how memory shows.

Thank you much for your replies. I know it's soldered on and i think that exactly some bad soldering is the issue, a contact may have come loose. I am actually able to fix it, if it is the case. I would prefer fixing it myself, otherwise it would take a lot of time getting it serviced somewhere else, so it would be the last measure for me.
My computer shows just 2GB of RAM everywhere you can look it up, although Lenovo's online hardware-testing software showed 4GB and therefore didn't find any problems (onboard diagnostic software still showing 2GB of 4GB instead of 4GB of 8GB- possibly mainboard-related problem)

Download CPUz from here:
Post the SPD and Memory tab screens.
Also post the memory screen from task manager/performance.
Use the windows snipping tool, save as .png, insert as photo in post reply.
I need to see how much memory is SYSTEM RESERVED.
Avoid any soldering on the motherboard. It is not as simple as you think.
