The following tutorial will explain the following topics
How to access the BIOS Setup
Choosing a boot menu
Start a system recovery
It is not the idea to explain every single option of the above, since many of them are complex and it would be too extensive for such a tutorial like this.
To execute any of the tasks above you need to press the button marked with the red arrow in the picture below:
Press the button when the Y3P is off! Use a small pointing device, I use the tablet pen of one of my Thinkpad tablets
Once you press the button you will be presented with the following screen:
Use the cursor keys to move up and down, press Enter to choose an option.
1) BIOS Setup
The BIOS is where you can get technical information about your device, as well to change boot parameters and setting up security passwords. Be very careful when changing certain values, since it can affect the way the Y3P works and/or affect performance and security settings.
It gives the hardware details of the Y3P, like CPU, installed RAM, SSD capacity and so on. This is a display only screen, no settings can be changed here:
Time and date can be changed in this screen. Furthermore to deactivate the Wireless LAN and enable the Intel Virtual Technology. If you plan to use Virtual Machine software in your Y3P this setting must be enabled
Passwords can be set up in this section. Secure Boot settings can be changed here.
Primarily designed to protect users from rootkits and other malware attacks by blocking unauthorized executables and drivers from being loaded during the boot process, it must be deactivated if you plan to install Linux or having paralel operating systems
Boot modes can be selected in this screen, you can disable booting from a USB stick or from a network for example
2) Boot Menu
This option is useful if you have Linux installed (using managers like LILO, GRUB, etc).
If you only use Win8 or higher there 's no much you can change.
3) System Recovery
This option will allow you to restore the system to either its factory setup, or to a previous backup done within Windows
A factory set up will leave the Y3P as it was shipped from Lenovo your private data and installed apps and/or programs will be wiped out. So make sure you have an external backup before such a reset
