My laptop has 16 GB of RAM installed, but Windows reports that only about 13.9 GB is usable. I’m not running a memory-heavy app when I check, and the figure is similar after a restart. The BIOS also recognizes the full 16 GB.
Is this kind of gap expected on a laptop, or does it suggest a memory module or configuration problem? I’d also like to know where Windows shows how much memory is reserved for hardware, since that might explain the difference.
