Windows 10: Not quite booting Solved

    Not quite booting

    I moved my (switched on) laptop to another room today. When I arrived at the other end, the screen was blank (no problem so far, sometimse I squeeze the power button by mistake and put it into 'hibernate'.)

    Tried to turn it back on but the power button had disappeared! The casing around it has been cracking away for ages, so I guess the button just fell out. I cant find it.

    The machine has a 'emergency boot' button I can use in-lieu of a regular start button. When I press it, the screen flashes up the manufacturer's logo splashscreen, the keyboard backlight comes on for a second, then everything goes off again.

    Sometimes it stays on an extra second and I can see the emergency boot menu (Start as normal, Bios settings, Boot menu, System recovery). I can use the up/down arrows to navigate that menu, but everything shuts down before any of them can be enacted.

    Very occasionally, it shows "repairing disc" (or something similar) before shuting off almost immediately.


    Sounds consistent with a disc failure? Anything else I should check? I wonder if the charger is dead and the battery is flat (as the machine sarts to boot for a second, then stops). The light next to the (ex) "on" button flashes white-off-red when charger is plugged in. Light does nothing when not plugged in.

    Would you expect that the initial boot starts from (say) a ROM chip and that is workign OK; until it hands over to the hard drive, so the boot fails?

    I stuck in a Linux boot USB and a proprietary emergency boot disk I made years ago, but as previous, the machine powers down before it boots properly.

    I also tried to boot it 'normally' by poking things down the hole where the 'on' switch used to be. Nothing.

    Where to start?

    Hi BobSter2.

    With your laptop powered off if you shake slight can you here switch rattling around inside.

    I believe you you are pressing the Lenovo OneKey recover button. Not sure if you had Windows 8.1 on this device and or how Win 10 was put one. Could be your recovery partition was deleted or has become corrupt.

    The key is to find button so you can issue a real power on. Your Yoga 2 has a more detailed model number, when I search I found numerous devices on their site. With model number you can search for a video on disassembly. This is not for everyone lots of pieces. That said you might find it is just a bezel to pry off to gain access to power button.

    Failing that I would get a price from a shop to fix.

    Forgot that I havent switched the machine off for a week, so it might have fallen out days ago.

    Broadened the search area and found it.

    Everything now A-Ok.

    Guess I need to find a way of keeping it there and also fixing the One-key recovery thing in case I need it. Don't expect the recovery partition to be corrupted, but I have a back up of it somewhere....

    case closed. Thanks.

    If your system was originally Windows 8.1 then there is little need to worry about it, it is stale dated, you're on Win 10.

    You could create bootable media using the Windows 10 media Creation tool although that will be v1709. Windows 10 also has a process to create a Recovery Drive which will create bootable media for your current version. Both of these are OS, not programs, not data.

    We also recommend a tool like Macrium Reflect to take system images.

    Glad to hear its solved.
