    Fast Boot BIOS issue

    well, I’ve a laptop, it’s a Lenovo V15-IIL.
    I updated to windows 11 22h2, so I had changed my BIOS settings from Legacy to UEFI. But the Fast Boot is ALWAYS ON, if I turn off the fast boot, it turns on.
    I’m saving the bios settings.
    And yes, I turned off the Windows Fast Startup.

    How old is the system the CMOS battery may need replaced.

      oh I don’t know, I bought this computer one year ago
      I thought is the CMOS battery, but if is the CMOS, why I can’t save just the fast boot setting?

        New Use still never stating the age of the system?

        How long did it sit on the shelf (per say) before you purchased.

        Something to look into.

          1. I’ll check
          2. I don’t know
          3. Because Windows 11 22H2 needs Secure Boot, i don’t know why, but if I use “BypassSecureBootCheck” in Registry it does not work

            Because it is a hack, and we so not support OS that are hacked.

              well… I changed OS optimized defaults from ENABLED to DISABLED and now the audio is better (i don’t know why) and the setting is still DISABLED. I changed Fast Boot to disabled too, but Fast Boot is enabled again…

                This should explain secure boot.

                Provides guidance on what an OEM should do to enable Securely booting a device

                Secure boot is a security standard developed by members of the PC industry to help make sure that a device boots using only software that is trusted by the Original Equipment Manufacturer (OEM). When the PC starts, the firmware checks the signature of each piece of boot software, including UEFI firmware drivers (also known as Option ROMs), EFI applications, and the operating system. If the signatures are valid, the PC boots, and the firmware gives control to the operating system.

                The OEM can use instructions from the firmware manufacturer to create Secure boot keys and to store them in the PC firmware. When you add UEFI drivers, you’ll also need to make sure these are signed and included in the Secure Boot database.

                Prior to the install of Windows 11 you did make sure that they TPM was active?

                That you confirmed the system is combatable with Window11?

                Plus made sure that prior no BIOS needed to be updated?

                  it is compatible because before using UEFI mode I had windows 11 (one of the first versions) with bypass files, now that I switched to 22h2 I used UEFI and I didn’t have to bypass anything

                    You are telling it to save the BIOS changes prior to exit.

                    Have you tried clearing the CMOS?
                    Something might be stuck causing this may clear it up.

                    You may also look into replacing the CMOS battery.

                    Is there an update that may correct the issue as well.

                      I want to avoid a BIOS update. I’ve been used to solving by trying everything leaving the BIOS update as the last option… CMOS battery? I actually thought about it, but the date still works fine even when it’s left off for days… if the problem was the battery CMOS shouldn’t it not save all BIOS settings?

                      P.S.
                      this is the first and last product that i buy from lenovo, there are few options in the bios, also i can’t even disable the boot logo, i would like to use the windows one instead i have to have that ugly rectangle with LENOVO written on it

                        I am sorry would have to see the screen a bit confused here.

                        Are you getting the login for windows 11 or is that screen coming up prior to the Windows 11 login screen?

                        Not blaming you a bit on the BIOS if not done correctly will brick the system.

                        @Bruce may have more ideas and suggestion.

                            know it sounds weird, but I think that’s the problem that’s causing my battery to drain. I know fast boot doesn’t cause this problem, but it’s strange that these two problems appeared together… I left the computer off last night, it was 70% when I turned it off, this morning I turned it on and it’s 63%… I mean… I have already changed the Windows settings of energy saving.
