How to find maximum ram capacity of laptop?

Answer 1

RAM (Random Access Memory) is the memory that your computer uses to store data from programs that are in use. Generally, the more RAM you have installed, the more programs you can run at once. The amount you can install, however, is determined by both your hardware and your computer's operating system. You will need to check both to figure out how much RAM you can add to your computer.

Part One of Two:
Checking Your Operating System

Determine if Windows is 32-bit or 64-bit. The Windows operating system has a maximum amount of RAM that it will recognize. If you have more RAM installed than is allowed, the extra RAM will not be used. This limit is determined by whether Windows is 32-bit or 64-bit.
See this guide for details on checking your copy of Windows. Generally you can see whether Windows is 32- or 64-bit from the System Properties window (⊞ Win+Pause)
32-bit can support up to 4 GB (for all versions) of RAM
64-bit can support up to 128 GB (Windows 10 Home) to 2 TB (Windows 10 Education, Enterprise, Pro) of RAM[1]
