ThinkPad E431 Press F1 to enter the system directly, unable to enter the BIOS

Lenovo's ThinkPad series notebooks are generally press F1 into the BIOS, but since most of the Lenovo notebook is pre-installed win 8 or higher version of the system, so sometimes there is no way to directly press F1 into the BIOS. The reason is because the fast boot setting is enabled in the win 8 or later system, which is because the system is booting too fast, so pressing F1 is no way to go directly into the system. Then know that can not enter the reason is good to do, we just need to set the quick start to do not start quickly can normally press F1 into the BIOS.

Here's how to cancel the Quick start. 1, open the Control Panel, (shortcut: Winkey+r open Run, input control), select "System and Security" 2, select "Power Options" 3, select the "Select power Button Function" 4, enter the "Select power button function" and then pull down, see "Shutdown Settings" 5, shown, if the Turn off set to gray non-change, pull up, click on "Change currently unavailable settings" 6, uncheck, save after the shutdown and press F1 (or FN + F1) can enter the BIOS normally
