It is pretty simple.  I foolishly bought another Kobo Glo and the power switch does not work.  The only possible fix is to replace the unit.  I don’t think Kobo is going to send me a new switch and a SMT repair kit to do it myself, but who knows.  Unfortunately after two weeks of emails with tier one, rather then just replace the unit, Team Kobo has sent me on a quest to find the mythical beast that is tier two:

Hi James ,

Thank you for contacting Kobo Customer Care. We have received the
photos as requested and have escalated your issue to our Tier 2 
support team. 

The Tier 2 team will try to provide a resolution as soon as
possible and will contact you if they require additional
information in order to resolve your issue.

Please let us know if you have any questions or concerns.

The Kobo Team

I can only hope and pray that I am deemed worthy of tier two, and that I am lucky enough to receive an email from them at some point in the future.  The fact that even when they do contact me, they will require ‘additional information’ does not bode well.  I can’t imagine what else they would need, unless this is just a ploy to wear me down to the point that I stop bothering them.  Stay tuned . . .
