Steps to reproduce the problem:
1. Press esc-refresh-power
2. computer shuts down, does not restart in mode to be wiped
3. 

What is the expected behavior?
Chromebook should accept command esc-refresh-power and move into recovery mode.

What went wrong?
Unsure.
I disenrolled the chromebook in the management console.  In order to have it get new info, need to hard boot.  Thought it was a faulty keyboard.  Replaced physical keyboard, still will not hard boot. Characters typed into guest mode are odd - the letter R generates random letters, symbols, and numbers for example. Attached external keyboard and can type fine but cannot issue key commands for a hard reset to get the OS reset.

Did this work before? N/A 

Chrome version: 53.0.2785.143  Channel: stable
OS Version: 6.1 (Windows 7, Windows Server 2008 R2)
Flash Version: Shockwave Flash 23.0 r0

Is there a way to command the Chromebook to do a hard reset without a functional keyboard?  Esc-refresh-power is not sending that key sequence to the computer. HP14" have no external holes (that I know of) to force a reset.
