    I would not make the use of that switch a daily activity. Mostly because it probably isn't setup for a long amount of cycles and I don't know how abusive it is to the memory holding the BIOS. The BIOS memory should hold out much longer than the switch but still.

    I swapped from my Crucial 1TB CT1000P1SSD8 NVMe to another Intel 660p 2TB SSDPEKNW020T8X1 NVMe. It does boot slowly without requiring intervention from my few reboot cycles thus far. I'll keep posted on my findings if I make any breakthroughs (or if a newer BIOS release fixes my issues).

    Can you try this fix in Win10 environment...

    When Windows is powered down, actually it's in "Hybrid Hibernation" state (for faster start-up) which is a sub-state of S4, not a true S5 state.
    Disable that feature, Windows then can go down to the full power down state.

    Procedure:
    Under PC settings, search "POWER", find the "Choose or Customize a Power Plan".
    On that page's left side panel, click "Choose what the Power buttons do".
    Click-n-check "Change settings that are current unavailable",
    Uncheck "Turn On Fast Startup (Recommended)".

    This disables the fast-startup mode and gets Windows to the full powered-down state.

    This was posted 6 months ago. Any update? This continues to happen regardless of OS apparently.

    This isn't specific to windows.

    My point: been suggested before. Didn't help then, doesn't help now.

    I'm almost positive this is due to the NVMe compatibility. Since changes to the Intel SSD over the Crucial I haven't experienced any hangs.

    The boot cycle is EXTREMELY SLOW but it at least completes now.

    The issue of the Bolt being stuck at b4 a0 on boot may be distro specific. Having previously used Fedora 31/32 without issue, I installed lubuntu 20.04 last night. After every boot of lubuntu 20.04, my bolt would stall at boot/reboot at b4 a0, requiring a uefi reset to work. I reinstalled Fedora 32 and have not had any issues. I wonder what Ubuntu is doing that is causing this problem. I may investigate if I have time.

    Interestingly, I also encountered the boot/reboot issue with my Bolt from simply using a Lubuntu 20.04 live usb before installing Lubuntu to my NVME.
