    I'm guessing that originally came with Windows 8? A factory install of 8 would be UEFI only, so hitting F1 etc isn't going to do anything. Usually you can get into BIOS/UEFI Firmware by holding shift when you click restart, and selecting UEFI firmware settings from the recovery menu that comes up. Since you can't get into Windows, the easiest way to get to BIOS is to disconnect the hard drive and anything else that with a boot manager. With nothing to boot to it should go straight into setup.

    You should probably check the health of the hard drive as well. It could be what's locking up the computer on POST.

    Have you tried updating to the latest BIOS? This is apparently a firmware bug.

    In some Acer Laptops there's a similar problem with BIOS. To solve that is quite easy:
    1. start the laptop and let it boot into the OS fully
    2. done that, using the OS function Restart, which is in Windows 10 from Start Menu --> Power --> Restart
    3. as the Laptop restart's, for a short time (few seconds) you could see on Screen a lower Taskbar with the available Hot-Keys, by Acer F2 for to go into BIOS!

    Don't remember which Lenovo were it, one I had in my hands, was use the ESC Key for to go into BIOS!!

    Anyway, you'll need to get the Taskbar on screen for to do any action. The reset of the CMOS may didn't change the security settings in BIOS at all!

    Could you ac cess the BIOS Boot Manager by booting the Computer?

    Maybe you could try the following, if it's a desktop:
    • open the Case
    • remove all cables from computer include the Power Cable
    • remove the Backup Battery, it normally a round battery Lithium 3V CR2032
    • short the 2 Battery connectors (+ / -) for about 5-10 seconds
    • place Battery back
    • connect KVM (Keyboard, Video, Mouse)
    • connect Power cable
    • start the computer and press the Hot-Key if when needed

    That Procedure should set back the MB-Watch to 00:00 and force user to open the BIOS.

    Hope that helps.

    Possibly your keyboard is disabled when booting. I would suggest you make use of a different keyboard. If you are using USB keyboard at the moment you can try PS2.

    Hi there i have just tired this 10 mins ago on what you said and still can't get in to the bios, can't access the bios boot manger by booting the computer on. It just loads straight in to windows 10. I have took all the cable's out even the battery out and all the other stuff you said to do and still nothing.:weep:

    Does Lenovo have a utility you can run in windows to change bios? Perhaps a utility to turn off fastboot?
    I'm thinking maybe there's something like a fast boot turned on in the bios that does not initialize usb until you've boot into the OS.
    I'm assuming your using a usb keyboard...

    disconnect the hard drive (Windows 10) and see if it loads the bios option by default

    Don't think so! It maybe will try to boot to Network!

    @clscragg2003: I could be wrong, just there maybe some keystrokes which triggers the BIOS to load at booting. Some Like that I had on a DFI Mainboard and was need to hit the Insert Key many times within the Boot Process!

    On the other hand, try to contact Lenovo Service/Support for to find out the way to get the access to the BIOS!

    I was digging a bit! Please look at the picture:

    [​IMG]

    Also, Windows 8/8.1 and 10 has Hybrid Sleep enabled by default! Go into Control Panel, power options, click on change when the computer sleeps over on the left. Then click on advanced options, sleep, then hybrid sleep. Make sure it's set to off.

    More, for to get the BIOS up, you may need to check F1, F2 and F12 Keys while boot the computer! F2 is normally used in Laptops only!

    Ok one more:

    At the end I really have to admit the same what other Lenovo Owner written on Internet: "No more Lenovo!"

    Have you tried to boot to firmware settings through 'Recovery' at the Settings?

    Let try this and see if it will work:

    1) Go to Settings and next click Update and Security.

    2) Under Advanced startup click restart now.

    3) Click Troubleshoot to continue after reboot.

    4) Choose Advanced options.

    5) Click UEFI firmware settings and click Restart and boot to your BIOS.
