  1. Thank you very much for this tutorial, thousands of thanks! Respect! I finally solved the problem that still made me sick.

  2. Per chi non avesse ancora risolto il problema della bassa luminosity dello schermo del Lenovo z500, si la colpa è dei driver, però non vi cervellate tanto, non so se qualcuno ha già postato questo methodo, il guaio quando si fanno i fari gli aggiornamento and you will touch the brightness adjustment with f-11+f12 keys.
    Turn off your PC by pressing and holding the f12 key, and you will see that the light is bright, you will see the beautiful illuminated Lenovo screen, you can leave the f12 key, and that's it.
    Provare per credere, un salutone a tutti
