i would if the screen showed anything at all, it shows nothing. The keyboard works and the windows button on the screen vibrates when I touch it after it's done booting, but that's it.

hmm.. i can't go into safe boot normally. Ok, he's what you have to do:
1. log into windows
2. press window+R
3. write msconfig
4. press enter
5. press tab 4 times
6. press right arrow
7. press tab 3 times
8. press space
9. press enter
10. press right arrow
11. press enter

the pc will restart and you will be in safe mode.
every time you restart it will be in safe mode until you open msconfig and select "normal startup" in the general tab.

normally pressing f8 or shift+f8 should bring you to safe mode but it's not working for some reason. maybe it's the quick boot in windows 8 that is messing it up.

i may be stuck in some other prompt because of all the hard reboots I did trying to get it to work just going to let it run and see if I can get the windows button working again then try these steps. 

 

I suspect that reformatting the SSD and installing windows 8 again would work but I don't have msata to sata adapter and I guess you have to take the laptop apart just to get at the ssd drive.. 

 

I see that in the past Comodo has caused looping and other issues with the security chip inside a lot of lenovo/thinkpad laptops. Don't know if it's the case here as well. (probably, though)

Then you should just use the warranty. Don't return it, otherwise you'll be put on the waiting list, just send it to get fixed.

ok, guess I'll contact them and get them to service it. Pretty annoying for something I can fix myself - but since you can't remove the ssd without voiding the warranty I guess there's no other way.

ok well after some more research I kind of jumped the gun on saying it's lenovo's fault. 

 

it could definitely be partially lenovo/comodo that caused the problem but the real route of the problem is probably windows 8 & fastboot. When I talked to tech support he said the OS is probably completely corrupt and I wondered why. 

 

Then I looked up how windows does fastboot and all these other features, it can cause the entire thing to go corrupt very easily especially if anything is buggy. 

 

I'm sending the laptop in for RMA but when I get it back one of the first things I'm going to do is disable fastboot, good idea but not practical. Basically when I'm running/testing stuff on any windows box I end up needing access to the bios/uefi there's always problems when I first set things up the way I want. Windows 8 basically makes it impossible with fastboot and the way the Yoga 2 Pro is setup. 

 

I'm a bit of a "tweaker" though so a regular user might be alright with it but I won't, and I don't want to have to RMA it every 2 weeks because I can't do anything due to fastboot.

well, even if I do it that way - I still have to disable it mostly because i intend to dual boot Linux.

 

I might even get rid of win8 and just use Linux on it, they do need to optimize a bit more for the high resolution in a lot of the X GUI systems. KDE seems to work the best at the moment with this laptop, though in general I prefer gnome.

The exact same thing just happened to me, I could have written the original post - Yoga 2 from Lenovo UK. Installed avast etc and everything was fine. Installed comodo, touchpad stopped working, screen was fine until the BSOD and reset. It seemed to turn on fine, but the screen remained blank,

I tried connecting a HDMI lead to my TV in the hope that the Yoga would connect but no joy. Tried the novo button, function keys etc. No luck.

Then the Yoga refused to turn on at all so I grudgingly called Lenovo to make a pick up. After a while, I tried booting again and it booted but, surprise, blank screen. Tried HDMI again but still no luck. I'm not really convinced that disabling fast boot would have solved the issue.

I loved the machine whilst it worked. It's really enjoyable to use but this has got me worried. Is comodo lenovo's kryptonite or are there numerous other potential conflicts lurking around every corner?

Even though I've made the pick up request, my other options are to return it for a refund and buy a new one or to buy a completely new system, I know that this was just bad luck on my part, but you can't blame me for worrying.

Alternatively, having it fixed could mean that it's tested thoroughly for other possible issues too. Might make it a little more resilient.

If anyone's wondering, I was quoted 10-18 weekdays for the repair plus 3-4 days either end for shipping to and from their international repair centre which means that I'm looking at around 4 weeks. Add in the time to receive the shipping labels (1 or 2 days) and the guaranteed holiday period factor, and we can safely assume that I'll never see my machine again.

Like I said, it was enjoyable to use whilst it worked, though.
