Topic: Laptop did only boot once
When I first plugged my Laptop in, I was a bit surprised it started up right away, without me pressing a power-button. Apart from that it wasn't surprising to see it boot up, create user etc...
I also did a apt-get update/upgrade and after that wanted to do a reboot. Shutdown from GUI seemed okay, but the backlight of the display stayed on, and I could not turn the thing on or off again. Even unplugging didn't turn it off. It finally turned off, when I unplugged my USB-Keyboard when AC was unplugged.
From then on, it didn't boot again. When I plug in AC, backlight goes straight on, but it doesn't boot. It turns off when I unplug AC.
The console says this
U-Boot SPL 2014.10-rc3-00039-gc5efead (Oct 17 2014 - 19:41:27) wait_for_sr_state: Arbitration lost sr=93 cr=80 state=2020 i2c_init_transfer: failed for chip 0x50 retry=0 force_idle_bus: sda=0 scl=1 sda.gp=0x5c scl.gp=0x55 force_idle_bus: failed to clear bus, sda=0 scl=1 i2c_init_transfer: give up i2c_regs=021a0000 Error reading SPD on DDR3.

I tried to boot with battery unplugged and reflash button pressed, but it doesn't help and the console gives the same output.
