    Hi,
    I just got a new Acer Nitro 5 AN515-54 laptop (9300H, Intel HD 630, GTX 1650). It's advertised to last 7-8 hours.
    It came with Linux Endless OS and I didn't gave it a chance and I installed Windows 10 right after I got it.
    The thing is when I installed all drivers except GeForce's one, it would on battery last for about 5 hours (idling/browsing) before shutting down.
    Once I installed GeForce's driver and without rebooting the system, it would last for about 9 hours. Note that it wouldn't affect gaming performance at all.
    But, once I rebooted it after drivers installation, it got down to 3-4 hours (idling/browsing).
    I've reinstalled Windows 10 thrice alreay trying to debug this but I couldn't yet and didn't find any solution.

    Using CPUID HWMonitor, I found out that in 1st stage (without any nvidia drivers), the CPU Package would consume about 8W (battery would last 5 hours). After installation and without rebooting, it would consume about 2W (battery would last 9 hours). Then, after reboot, it rose up to 15-20w (lasting 3-4 hours).
    Everytime I reinstall nvidia driver opting for clean install and without rebooting, it would last as supposed to, but this solution isn't good at all.

    I was wondering if someone has any idea for a permanent fix.

    Linux doesn't have native support for MSHybrid devices.

    This device is sold with Windows 10 Home.

    Yes, but where I live it's sold with linux so they can sell for competitive prices.
    Anyway, what I described happened on Windows 10 home.
    I think it has something to do with driver enumerator or regedit details, but I couldn't find out yet.

    Problem solved.
    It turns out it was either HWMonitor or MSI Afterburner avoiding dedicated graphics to idle.
