[Test]
Boot up the affected tablets to gdm without touching any physical keys, the on-screen keyboard should pop up.

[Where problems could occur]
Current BIOS is reliablely to report the tablet mode during probing intel hid driver, but when it fails, it may report the wrong state and show the on-screen keyboard when keyboard is connected.
