Lenovo B50-70 factory reset from recovery partition

To run a factory reset of Lenovo B50-70 from the hidden recovery partition:

  • Switch off the laptop.
  • Look for a small pinhole at the right side of the laptop, between the single USB port and the CD-DVD drive, closer to the USB port.
    At the first glance you may miss it, thinking that it is a kind of a LED indicator or even a miniature socket for earphones, as the OneKey Recovery symbol is very small and reminds of the headphone symbol.
  • Take a pointy object, preferably non-conductive one, e.g. a toothpick, insert it into the pinhole and gently push it. You will feel the miniature switch click. Keep pressed for about 2 seconds, then release and wait.
    The laptop then will switch on and boot into the special “Novo Button Menu” (it’s those  marketing people again…).
  • Select the “System Recovery” option and proceed in accordance to the instructions on screen.


I just wonder why those geniuses at Lenovo could not think of providing a simple and clear information on where to find the reset button. You can spend half a day reading manuals and calling up tech support, before you find it out all on your own.

It said nothing about the pinhole in any of the Lenovo manuals I read and the only information about it at the laptop itself was a marketing sticker boasting this function, without telling how exactly to activate it, only warning that “Some features are only available while running Microsoft Windows”, which does not help you much when your Windows has become unusable.

Go figure…

    Thanks, man. The only place on the Internet where I could find help. Like others said, there are no notions in the manuals about where one could find that dam button. Thanks again for sharing this info with us. You just saved us lots of time/nerves.
