In this article we will explain how to use the power button on the T10 tablet to allow you to use the power button as a Windows Security Button. This is needed when a local or domain security policy requires the user to input Ctrl+Alt+Delete before typing in their password. In order to set this up you will need to use a USB keyboard in order to gain access into the BIOS setup. When the T10 tablet is first turned on and a USB keyboard is plugged into the unit, you will need to tap the delete key repeatedly until you see the BIOS setup screen.
First verify that your BIOS and EC Version are up to date. The last two digits need to be 22 or later for the BIOS and 17 or later for the EC Version. .
Once inside the BIOS navigate to the Configuration tab and then the Power Management Setting menu.
Now change the setting for Power Button Action to Instant Shut Down.
The Power Button Action field should now be populated with Instant Shut Down.
Now navigate to the EXIT tab, choose Exit Saving Changes and choose Yes.
Now when Windows boots up and you get the following message, just tap the power button twice within a second to simulate Ctrl+Alt+Delete.
Finally login using the On Screen Keyboard.
