ChromeOS Version Requirements
TestNav on a Chromebook requires ChromeOS version 83 or higher.
First, at your chromebook's log in screen, check the version by pressing
alt and
V
and the same time. It will display the version in the upper right-hand
corner. If you are already logged in, this doesn't do anything, log out
and then press ALT and V to see the version in the upper right corner.

Hey! That chromebook says Google Chrome 72 (72 dot anything is still 72), which isn't 83, so this chromebook can't run the currentTestNav as is. But if you can coax it to update to version 83 or higher, you're in business.
Updating Your Chromebook
Note: if your chromebook is on version 83 or newer, you can ignore this section in purple.
Note 2: some chromebooks will be too old to update and can't go to version 83. Don't use them for testing.
Sign in to your Chromebook.
First, look at the bottom right, and click the area by the time. A menu should popup and give you access to the settings gear.
Second, click the settings gear.
Next, Look at the bottom left to see if "About Chrome OS" is there. If it is,
skip this step. Otherwise, look for the hamburger menu (three horizontal lines) with the word Settings at the top of the page.
Click Settings.
Now go to the bottom right and click "About Chrome OS"
Click the
Check for updates button.
It will either say
your chromebook is up to date, or it will slowly but surely download an update (sitting at 100% for a while) and then ask you to relaunch/restart so it can update. When the update button is ready, press it to restart.
Once it restarts, you can check your version of ChromeOS. At your chromebook's log in screen, check the version by pressing
alt and
V
and the same time. It will display the version in the upper right-hand
corner.
Hopefully, you'll see something like this:
![Google Chrome 85.0.4183.133 (Platform 13310.93.0-20.09.25) SN: [serial no. is blurred out] Asset ID: [asset ID is blurred out]](https://p19cdn4static.sharpschool.com/UserFiles/Servers/Server_801054/Image/Depts/OSS/Technology/Technology%20Images/TestNav/Chrome85.jpeg)
If it can't update past where it is (for example, one of the silver Samsung's model XE303C12 could only go to version 75 when a Chromebook Recovery USB thumbdrive was used), your Chromebook might tell you it's up to date even if it doesn't update to version 83; if so,
do not use that chromebook. Some ChromeOS devices in our system have reached or exceeded the date called Auto Update Expiration (“AUE”) which means
the Chromebook's hardware is too old to update; that chromebook is stuck where it's at. You can learn more here:
https://support.google.com/chrome/a/answer/6220366?hl=en
If you place a work order for a device that has reached or exceeded it's AUE, and you need it for testing, all we can do is get you a quote for a new Chromebook.
Where's the TestNav App?
First, if you are logged in, log out. Look at the bottom left of the screen for a place called "Apps".
TestNav is in Apps.
Make Sure it Works
Launch
TestNav by clicking on it in the Apps menu, click on
Tennessee on the
Where do you want to go? screen.
Here's the part you won't like: if you're on an older version of ChromeOS (older than Version 83), you will have a TestNav app. But when you click on Tennessee to try and launch the thing, you'll see an error screen that says something like this:
ERROR 3108: Operating system version not supported.
If you see that, then your operating sytem version is not supported; use
the steps in purple (above; the section titled
Updating Your Chromebook) to help you update your device. If your
device cannot be updated, then it cannot be used for testing.
Then, assuming you've gotten this far without an error, click on the icon in the upper right corner
icon (looks llike the head and shoulders of a human). One of the options
in the dropdown menu is App Check.
Click on App Check. Another box appears, and two blue buttons, on says
"Run App Check" the other "Run Network Check". (Note: you don't have to
run the "Run Network Check" utility, unless you want to. The network
check tests if your school's network can support x amount of machines;
You tell it a number such as 100, or 743, or whatever. It will indicate
if it passes or if it detects the possibility of difficulties or
failure).
Click the
Run App Check button. Note: your screen may flash and TestNav may resize itself.
When it's finished, it will say, "
App Check is complete."
As of this writing, a successful check has two green boxes, one that
has a checkmark and the words "Kiosk Mode Passed" as well as one with a
checkmark and the words "Connectivity to TestNav Passed".
If your results do not indicate success,
and your chrome device is on ChromeOS 83 or later, a technology work order needs to be submitted. Please indicate the machine
failed the App Check for TestNav. We need the
barcode of the computer so that in case you are out for any reason we can identify and work on the computer prior to the field test.
When you are finished, you may click the
Back to Sign In button if you need to continue using TestNav or you may exit the program if desired.
