I haven't got an reply from Shearwater if I'm allowed to post this so I consider silence as "yes".
TL;DR:
the computer screen suddenly went black and was off for the whole dive, then suddenly started to work after a few hours at the surface. I've sent the computer to Shearwater and after two weeks got a new computer back (would be about 1 week if I lived closer to the service center). Paid only for the shipping to them — return shipping was free.
I'm too lazy to rephrase what happened so I'll just quote an email I've sent to Shearwater.
I've shipped the computer to the nearest service center (only computer alone, without box etc) and asked to ship back only the computer too as I do not need extra bag, charger and all the excess waste. But anyway they've shipped back the whole new box, so now I have two chargers, two bags and everything else
If I would sell the extra charger it will be the same as the shipping cost so I consider that the service was totally free of charge.

some strange thing happened with my Teric two days ago. Everything was ok on the first dive and on the surface interval, then we went to gear up for the second dive and after putting my equipment on I noticed that Teric screen is black. I pressed the Light button twice (as I usually do to turn Teric on from the sleep mode or to move it from "Off" to "Dim" and "Low" brightness) but nothing happened. Then I tried to press all buttons, and to press and hold - still nothing, the screen is black.
I thought that computer might get overheated, because it was laying under the direct sun for 5-10 minutes while I was gearing up, so I decided to jump into the water with it and see if it will cool down and turn on. And immediately after I jumped into the water Teric beeped and vibrated (going
into the dive mode), but the screen still was black! So the computer was working all that time. I tried to press Light and all other buttons while under water but nothing happened, and the whole second dive the screen was black.
When we came back to the surface the screen still was black, and after about one hour on the surface I tried to press the Light button twice to see if something changed, and surprisingly the screen turned on showing the owner's contact information, computer beeped and vibrated and proceeded to the dive mode.
It would do the same (turn on and immediately go into dive mode) if it was turned Off during the dive mode before, but I checked the Log and saw that the computer tracked the whole second dive, so it definitely was not accidentally turned Off during the dive when I randomly pressed the buttons trying to turn the screen on.
