I have 8gb of ram available but only 3.46 is usable on my windows 10 lenovo laptop. I tried doing a BIOS update but it did not update, it said u need a G50-45 build to update. I did have it but my warranty had expired, maybe the reason. I want to know how I can make my laptop use more of the ram that is available. Thank you.

If you keep it as it is, it'll just be a redundant piece of hardware drawing extra power. Just remove it and replace it with a compatible module.

As for performance, Windows 10 performs best with 8GB or more RAM.

    The bios is restricting one of the modules so windows is allocating hardware reserved. This may mean it is faulty or the wrong type for the computer.

    The only way to resolve this will be to buy a new memory module. You cannot resolve it by changing windows settings.

    You can try windows memory test, type memory in Search and select Windows memory Diagnostics or use Memtest64 (perhaps the better option) from their website and run a full test. https://www.memtest86.com/

    Thank you. Let's try this, please:

    Select Start button and type Regedit, then right click over the app and select Run as administrator. Next expand the following path:

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management

    Double click over ClearPageFileAtShutdown and change it value from 0 to 1. Next restart your computer and verify again the available ram.

    Shows the same (3.46 usable) on settings.

    Also, I did the memory diagnostic with built in app, but how do I check it
