Do NOT install Comodo antivirus software. I and at least two other Y2P owners have had issues with the software causing a conflict which results in the machine booting without the displaying coming on. Due to the fastboot, it's impossible to then get into the BIOS or safe mode. I've just sent my 1 week old machine back for 'repair' today.
I thoroughly recommend disabling fastboot on your machines. Although I'm not 100% certain that it would have allowed me to effect any remedial changes, it would have at least been worth a shot.
If anyone has come across any other strange quirks/conflicts, it would be great to create a sticky listing them all with workarounds/remedies where possible. The aim is to just warn people off making a mistake and also helping out those who have already done so.

There is a 2nd thread reporting identical problem: https://forums.lenovo.com/t5/Idea-Windows-based-Tablets-and/New-Yoga-2-Pro-Impossible-to-turn-screen...
A very frustrating problem with no apparent solution other than return to manufacturer for "repair".

Yes, had possibility to brick two same Lenovo Yoga 2 Pro-s after 1 day use. Returned from repair to retailer w exchanged motherboard and reinstalled software. I'm not sure if I would like to test it again.
Tried also Lenovo ThinkPad Yoga 1S (business version of the Yoga 2) but skipped Comodo CIS test this thime. Did not liked the smaler screen and the cooling system. I think it is the same problem w excess heat of this two models.

I am using Comodo AV and Kiosk and Sandbox fine on my Yogo Pro 2 - I found the cause of the conflict.
I was one of the early Coma victims. The root cause was Geekbuddy and/or one of the other "free" apps that comes with the AV Suite. One of the members of this forum point to an incompatibility with EFUI and they are correct. the offending applet had a very early load driver conflict with Safe Boot stuff (I do not understand tiny details) and locked it up = coma. Once I defeated the fast boot and put the system into Legacy BIOS compatibiliyt mode - AND removed the offending applet by going back to factory image - I was able to install JUST the Internet Security package with AV....no Geekbuddy.....no Dragon browser. It all works fine and I am very happy with Comodo functionality.
It is a shame that the testing of the EFUI compatibility with Geekbuddy and maybe Dragon was so poor IMHO....but when I called them and said to the tier one tech "I want to escalate and talk to a tier 2 or 3 tech who knows about EFUI conflicts - I got to a guy that admitted - "Yes we have a problem - just install the core package and you will be OK"
Re opening the case vs. just waiting.......I opened the case and used the correct tools (VERY IMPORTANT) to pull the battery connector off . I am too impatient and too experienced to be be worried about the warranty question - besides I had the Lenovo Service Manual from their site - so I could see in advance that it was a 2 minute job.

First time I saw this issue about october 2013. It's on Yoga 13, Yoga 11s, and Yoga 2Pro (don't know about other ThinkPad Yoga series). After install Comodo Antivirus package, after a few hours Windows get really slow, touchpad stop working, keyboard stop working, sometimes there is a bluescreen "watchdog violation", sometimes machine just restart itself. On next start of laptop:
Definitely not depends from:
It all what I know, I hope it help.
