See if the computer can install two or more memory modules
Method 1 (not very accurate):
Because the computer itself has two slots, the number of memory modules that can be loaded on my computer is two, and I can install another memory module. 
Method two (more accurate):
Check the number of channels. Single-channel means only one memory slot, and dual-channel has two.
Computer memory specifications
DDR3
Memory frequency
1600Mhz
Voltage
Low voltage 1.35v
Maximum memory supported by the computer
- Command line window-cmd
The number obtained by calculating the maximum memory divided by 1024*1024 is the maximum memory supported by the computer
16777216 divided by 1024*1024 is equal to 16, that is, the maximum memory supported by the computer is 16, and you should not exceed 16g when you buy it.
Memory module installation
This is relatively simple and rude, just turn on the computer to find a slot, and just put the purchased one in.
To check whether the installation is successful, the simpler is My Computer-Right Click-Properties. Installed memory = original notebook's own + new installed.
