I have two problems:
- When shutting down the device it goes off, but can start up by itself and it seems to be randomly (For instance you can shut it down in the evening and the next morning you find it powered up)
- When suspending the device it goes in sleep mode and the power button is slowly blinking blue. Usually you just push the power button and the device starts up, however now it has happened three times that nothing happens when pushing the power button. The power button still blinks slowly. I tried to power reset the NUC (unplugging the power) but then the power button is just dead and nothing happens when pressing it.
Around three months ago I bought this NUC together with the following parts:
2 x Corsair 1600 MHz SO-DIMM DDR3L 4GB 1,35v
Intel 525 series 120GB SSD mSATA
Intel Dual Band Wireless AC 7260
I upgraded BIOS (025 at that time) and installed Ubuntu 14.04 LTS. When BIOS 026 was released I installed that which fixed the problem with WiFi disconnections I experienced.
Around a month ago I experienced problem no 2. Nothing happened when pressing the power button. I returned the NUC to where I bought it and they checked it and it ended up with that they exchanged it to a new device.
When I got the new NUC the BIOS 027 had been released so I upgraded to that one. Not so long time after I got the new NUC, problem no 1 started and problem no 2 has happened two times.
1. This happens more or less every time when shutting it down. I haven't found any pattern when it starts up automatically. It can start up after a few hours after shutting it down. Sometimes I find it started up the next morning. Sometimes I shut it down in the evening before going to bed, the next morning it is still off and when I come back from work its on.
2. The second time the device stopped responding when pressing the power button, I started to search this forum and found some suggestion to recover from this state. Un-/re-plugging the CMOS battery helped. However when it happened yet another time (yesterday) that made me writing this hoping to get a permanent fix (or confirmation that the device is broken). It's pretty annoying to have to open the case and unscrew the main board to get to the battery every time the NUC locks up.
