My P650SG (Dia 15) that I ordered from Mythlogic in March 2015 had been having intermittent issues with clicking for the last 6 months. The left mouse button would "stick" and act like it was held down. Tapping it a few times were generally resolve the issue. However, now it's completely gone- not registering anything at all. I opened a support ticket with Mythlogic as I purchased a two year warranty with them: 9/14 - opened ticket requesting support with detailed issue notes 9/21 - requested an update to the ticket via email, still haven't received any response 10/4 - request an update to the ticket via email, still haven't received any response. Threatened a credit card chargeback on the extended warranty cost and the dollar amount needed to pay someone else to repair it if they continue to ignore me. 10/5 - Mythlogic reponds with two sentences asking for clarification (I'm in Germany so this came in during the night) 10/6 - Sent back more info to Mythlogic 10/20 - requested an update to the ticket via email, as I still haven't received a response. Gave them deadline of next week to respond before I go ahead with the charge back I threatened on 10/4 and take it somewhere else for repair. So in the course of 5 weeks I've only gotten a two sentence answer from Mythlogic - no offers to repair, no help at all. I paid $80 I think for the extended warranty on a $1900 laptop that still has a nonfunctional trackpad. They used to be well known around here for their support, but it seems like no one is working for them doing support anymore. EDIT: Final update. Laptop was shipped back to me on 11/21. Got it today and my mouse works again! They also fixed the speakers that died the weekend I was getting it ready to ship back. I thought it was related to the Windows Anniversary update I got the night before, but they said the speakers actually died.
