Hello there,

i have problem with my new laptop Lenovo ThinkBook 15-IIL Mineral Gray. I enabled option called "POWER-ON PASSWORD" and set user password to "blahblah" in system setup. When i turned off this laptop, turned on it again, the screen was fully black and the only working thing was keyboard. I wrote the password "blabblah" and Windows loaded perfectly.

But, i wanted to remove this password. Once again i entered system setup and i tried to remove user password by choosing this option, entered current password "blabblah", the new password i left empty and accepted all changes. Now, when i press power button, the screen is still full black, pressing just "enter" (cause of empty "null" password) is not working, password "blahblah" not working too, pressing F1 to open system setup not working,

What can i do for boot to windows?

Thank u a lot guys and sorry for my english.
