I want to upgrade current 2GB RAM of my X200MA to 4 GB. However, to retain 2-year warranty (I have just bought it within last 3 months), I have to do it through warranty department. I called them and they said I had to obtain the RAM and they would install it.
My problem is whether to buy a 2GB RAM stick or a 4GB because I don't know how many RAM slots it has. popular programs such as hwinfo32 and Speccy did not show the number of RAM slots, but Windows 8.1's Taskmanager says "1 of 2 slots used" for RAM. By the way the system is so densely packed, thus without a simple back cover for RAM unlike many laptops, so I cannot open the case myself.
Is there a reliable program to show number of RAM slots? I ask because in case of it having only one slot, I have to buy a 4GB stick to replace the current 2GB. Otherwise (two slots), I can add another 2GB, which is much cheaper than a 4GB, alongside the existent 2GB one.
RAM analysis reports are as follows in Speccy,Hwinfo32, and Windows 8.1 Task Manager, respectively:
Speccy:

A search quickly found this:
It says there is one slot.
9The RAM is onboard. I had it opened by a technician to see if it supported RAM extension. Unfortunately, there were no slots. The RAM is onboard for this notebook. That is to say, it is part of the motherboard.
