that was a lot.
2015-01-04: recovery media - in Chrome on my Chromebook, I went to chrome://imageburner and got the "Create OS Recovery Media" screen. I inserted a 8 GB usb stick (Kingston DataTraveler SE9), it warned me that all files on the stick would be erased, I pressed "OK". First it downloaded a recovery image (488 MB), extracted it, then started to copy it (1.5 GB) and then said "Your recovery media is ready. You may remove it from your system." 2015-01-04: battery - it seems the battery is not charging. The battery LED is blue (its should be red if charging) and the machine turns off if I unplug the power adapter. I tried a powerwash. It didn't help. When I turn off the Chromebook, the power LED blinks red. I measured the voltage from the power adapter (with my multimeter) - yep, it is 12 volts. I let the machine sit for many hours with the power adapter connected and the machine off - didn't help, the power led is still blinking red.
2015-01-03: I created a Google account. From Settings, Language and input settings, I could select "Norwegian" and Norwegian keyboard.
2015-01-03: first power on. I followed the quick start guide. Plugged in the power adapter, and opened the machine. It powered on, displaying a nice wallpaper and asking me to select language (English), keyboard (Norwegian was not available so I selected Swedish keyboard), connected to my (wireless) network and selected "Continue". Then I had to accept the Google Chrome OS Terms - this screen also had "System security setting" (TPM password) and "Accessibility". Next Chrome OS updated, before asking me to sign in. For now I selected Browse as Guest". After a while the panel (or whatever it is called - status tray) showed "restart to update" so I did.
2015-01-03: the Chromebook 2 has the following connectors on the left side (from back to front): DC input from power adapter, usb 3.0 (chargeable port), HDMI connector, micro-SD card slot. O the right side (from front to back): headset jack, usb 2.0 (chargeable port?), security slot.
2015-01-03: I picked up the package from Dustinhome today, at my local PIB (Rimi Trondheimsveien). The packaging contains:
1 x Chromebook 1 x power adapter (output: 12 V DC center positive, 3.33A) + power cable (the end that goes into the power adapter has the "Mickey Mouse" style plug) 1 x plastic bag with documentation: 1 x warranty information, 1 x 503C12 / 503C32 Quick Start Guide, 1 x Samsung Cromebook "Programvaruguide" (=software guide) which are offers for 1 year free AirDroid Premium + Wunderlist Pro + free lessions in Little Bridge.
2014-12-29: Sale on Dustinhome.no, and I found a Samsung Chromebook 2 (5010782006) for NOK 2490.- and this was the model with a full-HD display, so I bought it.
