I'm seeing quite a few 'SUS Power Fail' in the event log and wanted to know what exactly this means and/or any documentation on it. The machine i'm currently working on came in with a service call about 'machine is randomly restarting'. I would expect to see some Kernel Oops/Panics but I only see instances of SUS Power Fail. An example of the event log:

Thanks for posting in the Community,
Do you experience any issues related to the SUS Power Fail in the event log, such as power / sleep related problem? Are you still experiencing random restart problem?

Hi there! This could be a driver error, let us run the Lenovo Vantage then test all the hardware. Pull up Lenovo Vantage if you have it installed then go to hardware then run the scan. Update us with the result.

Hi pwirsch, Thanks for writing in. We recommend performing the troubleshooting steps below to isolate the problem. There is a high possibility this issue is caused by a faulty battery or driver.
Test the Battery Health
To test the Chromebook battery health:
1. Power on the Chromebook, and sign in or use “Browse as Guest” to enter the Chrome OS.
2. Press Ctrl + Alt + T to open the crosh window. Crosh opens in a new browser tab.
With the AC power attached, run the below command:
Disconnect the AC power, and run the below command
Your battery is good if all the followings are met:
• The battery is charging.
• The battery health is 50% or greater.
• The system remains powered on during the 10-second test.
Your battery should be changed if any of the followings is met:
• The battery does not charge.
• The battery health is below 50%.
• The system immediately turns off when you remove the AC power.
• The battery is show as “Unknown” when you remove the AC power.
System reset.(Deletes all files on machine)
Sign in to your Chromebook.
At the bottom right, select the time.
Select Settings Settings.
At the bottom, select Advanced.
In the "Powerwash" section, select Powerwash and then Restart.
In the box that appears, select Powerwash and then Continue.
Follow the steps that appear and sign in with your Google Account.
Note: The account you sign in with after you reset your Chromebook will be the owner account.
Let us know if this helps. Thanks.

I work with pwirsch, and can speak for him (though he'd probably argue with me if he saw me say that!)
The battery health on each of these devices is much greater than 50%, and we routinely powerwash the devices.
In addition to the troubleshooting steps you've provided, we have also performed diagnostics using the RMA Shim, and usually there is no hardware fault identified during these tests.
