Here is a workaround, obnoxious if you are trying to read in a dark room.
When you hit the power button to bring it out of sleep, expose it to bright
light. That seems to reset the Auto Brightness to something useful.
Remember that the power button is a sleep toggle, if you hit it a second
time immediately it will just put the machine back to sleep. The power
button has the normal "Fail to unlock" timeout and it will perform a wakeup
again after this timeout - this is the normal action for a user "Check Status
or Time" on an Android phone.

My system replicates the issue. I'm quite curious what problems the user two entries above has had that required service three times. I'll look forward to Lenovo correcting this brightness issue--it is rather strange not to have a patch, months later.

Thank you very much for explaining. I'm new to the forum, new to a K1, and new to tablets in general. I have long admired Lenovo, though. This particular machine really strikes me as a departure from their usual quality, and I appreciate your summary of problems. Just to sympathize: I had to send mine to service immediately: despite that I knew how the micro-SD card slot works, knew that the card went in at an angle, and have been working on computers my whole life, I managed to stick the card in _above_ the slot and bury it completely in the machine. That's my one return to service. I think most of the difficulties I have with the tablet relate more to Android, which I think is a quite promising operating system, but one that is not yet ready for productive uses on the market. I'm seriously considering changing out this machine for the Thinkpad tablet, which has features which remind me much more of a laptop (or desktop) system, and most of all reminds me of the X41 and X61 notebook-tablets I loved so much.
