For general -information about getting started with developing on Chromium OS (the -open-source version of the software on the Chrome Notebook), see the [Chromium -OS Developer Guide](/chromium-os/developer-guide). - -### Specifications - -* CPU: Intel [Sandy Bridge](http://en.wikipedia.org/wiki/Sandy_Bridge) - Celeron (might vary on specific model) - * Some later models shipped [Ivy - Bridge](http://en.wikipedia.org/wiki/Ivy_Bridge_(microarchitecture)); - those will use the parrot_ivb board -* GPU: Intel [Sandy Bridge](http://en.wikipedia.org/wiki/Sandy_Bridge) - Mobile - * 11.6" 1366x768 16:9 - * HDMI port - * VGA port -* RAM: 2 GiB or 4GiB DDR3 (might vary on specific model) -* Disk: 320 GiB HD or 16 GiB SSD (might vary on specific model) - * USB expansion ports - * [SD slot](http://en.wikipedia.org/wiki/Secure_Digital) (SDXC - compatible) -* Networking - * WiFi 802.11 a/b/g/n - * Dedicated Ethernet port - * USB ports can handle Ethernet dongles -* Power supply: 19V <img alt="image" - src="/chromium-os/developer-information-for-chrome-os-devices/direct-current.svg" - height=5> ([DC](http://en.wikipedia.org/wiki/Direct_current)) 2.15A - <img alt="image" - src="/chromium-os/developer-information-for-chrome-os-devices/center-positive-polarity.svg" - height=12> ([positive polarity - tip](http://en.wikipedia.org/wiki/Polarity_symbols)) -* [Kensington Security - Slot](http://en.wikipedia.org/wiki/Kensington_Security_Slot) -* [Servo header](/chromium-os/servo): 1x50 header (now obsolete) - -## Developer Mode - -**Caution: Modifications you make to the system are not supported by Google, may -cause hardware, software or security issues and may void warranty.** - -An unrelated note: Holding just Refresh and poking the Power button hard-resets -the machine without entering Recovery. That's occasionally useful, but use it -with care - it doesn't sync the disk or shut down politely, so there's a nonzero -chance of trashing the contents of your stateful partition. - -### Introduction - -Enabling Developer mode is the first step to tinkering with your Chromebook. -With Developer mode enabled you can do things like poke around on a command -shell (as root if you want), install Chromium OS, or try other OS's. Note that -Developer mode turns off some security features like verified boot and disabling -the shell access. If you want to browse in a safer, more secure way, leave -Developer mode turned OFF. Note: Switching between Developer and Normal -(non-developer) modes will remove user accounts and their associated information -from your Chromebook. - -### Entering - -On this device, both the recovery button and the dev-switch have been -virtualized. Our partners don't really like physical switches - they cost money, -take up space on the motherboard, and require holes in the case. - -To invoke Recovery mode, you hold down the ESC and Refresh (F3) keys and poke -the Power button. - -To enter Dev-mode you first invoke Recovery, and at the Recovery screen press -Ctrl-D (there's no prompt - you have to know to do it). It will ask you to -confirm, then reboot into dev-mode. - -Dev-mode works the same as always: It will show the scary boot screen and you -need to press Ctrl-D or wait 30 seconds to continue booting. - -### USB Boot - -By default, USB booting is disabled. Once you are in Dev-mode and have a root -shell, you can run: - -```none -sudo crossystem dev_boot_usb=1 -``` - -and reboot once to boot from USB drives with Ctrl-U. - -### Legacy Boot - -Sorry, but this device does not support a legacy BIOS mode. It predates the -launch of that feature and it is not feasible to produce updates of devices in -the field. - -### Leaving - -To leave Dev-mode and go back to normal mode, just follow the instructions at -the scary boot screen. It will prompt you to confirm. - -If you want to leave Dev-mode programmatically, you can run `crossystem -disable_dev_request=1; reboot` from a root shell. There's no way to enter -Dev-mode programmatically, and just seeing the Recovery screen isn't enough - -you have to use the three-finger salute which hard-resets the machine first. -That's to prevent a remote attacker from tricking your machine into dev-mode -without your knowledge. - -## Firmware - -This device uses [coreboot](http://www.coreboot.org/) and [Das -U-Boot](http://www.denx.de/wiki/U-Boot) to boot the system. You can find the -source in the [Chromium OS coreboot git -tree](https://chromium.googlesource.com/chromiumos/third_party/coreboot/+/firmware-parrot-2685.B) -and the [Chromium OS u-boot git -tree](https://chromium.googlesource.com/chromiumos/third_party/u-boot/+/firmware-parrot-2685.B) -in the `firmware-parrot-2685.B` branches. - -## What's inside? - -**WARNING: Opening the case and fiddling with the stuff inside could easily -brick your system and make it unrecoverable. DO NOT ATTEMPT if you are not -familiar with this process.** - -### Disassembly - -Taking apart your laptop is **not** encouraged. If you have hardware troubles, -please seek assistance first from an authorized center. Be advised that -disassembly might void warranties or other obligations, so please consult any -and all paperwork your received first. If you just want to see what the inside -looks like, gaze upon this (click for high res versions): - -[<img alt="image" -src="/chromium-os/developer-information-for-chrome-os-devices/acer-c7-chromebook/acer-c7-bottom-guts.jpg" -height=221 -width=320>](/chromium-os/developer-information-for-chrome-os-devices/acer-c7-chromebook/acer-c7-bottom-guts.jpg) - -[<img alt="image" -src="/chromium-os/developer-information-for-chrome-os-devices/acer-c7-chromebook/acer-c7-top-guts.jpg" -height=226 -width=320>](/chromium-os/developer-information-for-chrome-os-devices/acer-c7-chromebook/acer-c7-top-guts.jpg) - -However, we acknowledge that some people like to tinker. So here's a quick guide -to taking it apart. - -#### Access to upgradable/cleanable components - -This is very easy to do and gets you access to all the pieces you most likely -care about: - -<img alt="image" -src="/chromium-os/developer-information-for-chrome-os-devices/acer-c7-chromebook/acer-c7-case-bottom.jpg" -height=277 width=400> - -* The hard drive is easy to remove & replace/upgrade - * 2.5" SATA 2 or SATA 3 drives should work - * try to get a 7mm tall one (9.5mm will fit, just sans padding) -* The two memory slots are easy to access - * The system uses 204-Pin DDR3 SO-DIMM laptop memory -* The wifi module is easily removable (one screw) -* The exhaust fan is easily removed (two screws) for cleaning - -And here's the details (see image on right for more details): - -* Get a smallish phillips head screw driver -- all screws can be - removed with just this -* Shut the system down and close the lid -* Flip the laptop over so the bottom is facing up and the warranty - seal is closest to you -* (Step 1) Break the seal that says "warranty is void if seal is - broken" -- be aware, you might void your warranty by breaking the - seal :) -* (Step 1) Remove the single screw under the seal -* (Step 2) Remove the battery - * (Step 2a) There is a slide near the edge of the battery in the - upper right section -- put the tip of the screw driver into the - divot and slide it to the right to unlock the battery - * (Step 2b) While the battery is unlocked, pull it out -* (Step 3) Place your thumbs on the bottom two feet and pull towards - you - * Alternatively, you can pull on the edge where the battery was - -Check out the high res picture above for overview. - -#### Access to the rest of the machine - -While it is possible to remove the motherboard entirely, there isn't much of a -point. You can see a high res image of what it looks like above if you just want -that.<img alt="image" -src="/chromium-os/developer-information-for-chrome-os-devices/acer-c7-chromebook/acer-c7-bottom-screws.jpg" -height=222 width=320> - -If you really want to remove it, then here's how: - -* Remove the 18 screws holding it down (does not include the warranty - screw) - * 4 screws: one next to each of the rubber feet - * 11 screws labeled M2x6 (including one on the cooling fan) - * 1 screw labeled M2x3 (near the memory module) - * 1 screw on the the cooling fan (kitty corner to the M2x6 one) - * 1 screw on the wireless module - * You do not have to remove other screws (like the ones around the - cpu) -* The top part of the case is now held to the bottom by plastic tabs - around the edge -* Turn the computer onto its side and slowly pry it apart - * Switch between the sides to slowly work it apart - * You can press on the center of the motherboard where the empty - memory slot is to help - -#### Firmware Write Protect - -It's a jumper next to the CPU under the black plastic. See the pictures above -for more details.
