I don't use autobrightness, 'cause I almost always work on the least brightness 
It is enough for me and the battery lasts very long then.
@mpman
I noticed that when the mini-jack is plugged in to the tablet (headphones, jack-jack cable et.c) it takes a lot of time to him to this "random from stand-by awakening", sometimes the K1 doesn't even wakes up at all (unless of course I click the power button). Check out do you have the same issue, I really have no idea what does the plugged mini-jack have in common with waking up from stand-up, but it kinda eliminate this problem. Guess I will have to cut off the mini-jack from some cheap headphones and plug it in, it won't disturb in big way but reduce the problem and battery usage.
Please answer mpman what about your tablet and this way
And if anyone know better solution please help!

Well then I don't really know what's going on... the mini jack trick helps a bit for me, but it still a problem... Yup, something wakes up the tablet, but I still don't know what
@Clear_Blue_Lou
At the beginning I also thought that maybe these random wake ups were caused by checking for email, updates etc. But I tried turning off things - I turned off email synchronization, I turned of Wifi, I even uninstalled some programs and widgets (like the weather widget). All of that without any results, it keep happening... I don't know what to uninstall or disable (if the reason is in the software of course). But maybe I overlook something, I will try again today... Thank you for your reply, if you have other ideas please write them down
If anyone has a clue, please share it!
The power button cannot be defective, because I could turn on and off my tablet as well as turn the standby on and off 
It also never gets into standby by himself - I use "screen never locks up" option, and every time I leave the tablet on (even for a long time like 30 minutes or more), it never gets into standby. So as it doesn't happen both ways it cannot be a mechanical problem connected with defected power button
And yes, I use a professional case designed for 10,1 tablets with few layers etc. because I travel car a lot so I must have a mechanical protection during the travels. I don't get how could that be connected with my tablet, I don't use it when it's in case, I get the tablet out of the case and then use it, and that's when the problem exists
I think it must be software... but what?
Anyone? )
Lots of greeting,
Mattata
Hello again!
I have to say that somehow this issue stops bothering me
I don't know if it happened due to Android upgrade, getting rid of some appication or just a coincidence, but my K1 doesn't waking up randomly now. Hope it will last forever!
I will try to find out what helped me with this problem, and if I'll learn something I'll let you all know, so you could also easily get rid of this stupid and annoying issue!
But...
in case it starts again (knock knock ), I have to ask - do someone had this problem and surely (I mean, 100% positively) knows by what it was caused?
Greetz!

Hi, arifonline!
I checked the tablet's info and it looks like this:
Android version: 3.2.1
Kernel version: 2.6.36.3
Somehow all works fine right now, but I'm not 100% sure if it was the update which helped me. I also un-installed and re-installed a lot of programs (one of them could cause this issue). I dunno know yet the exact cause.
Do you have an idea?
P.S. I never had a dead unit due to update or sth...
Greetz,
Mattata
