An interesting thing I didn't know until today. On one laptop (tested on a notebookToshiba) cuWindows 8.1 The keyboard can be blocked total yes unlocked with the help of a combination of keys. Windows Keyboard Shortcut.

A little weird is that a blocked laptop keyboard can be unlocking from a Combination the Taste. All we have to do is press the keys simultaneously: CTR + ALT + L to unlock it.
There are also cases where the keyboard can be debocked due to problems hardware or of driver. In these cases it is recommended either to connect an tatuti external Until the problem is remedied, or the connection to the laptop with the blocked keyboard, through a remote control program. TeamViewer for example.
