Power off issues

Hi,

I've been chasing an odd issue. I've found my bolt with an amber light multiple times now, it's on a UPS, there are other devices on the UPS which don't power cycle.

Is there any way to find out from the BIOS why I'm seeing the box at amber instead of green?

OS doesn't show any type of requested reboot or shutdown, so I'm thinking this might be a bad PSU.

Thanks in advance for your thoughts.

What OS are you running? I have found that with Windows 10 I can get unexpected crashes/shutdown unless I if I do not the EMMC device in Device Managet.

 

In the BIOS in the Embedded Controller menu there should be Reset Causes Handling, could help.

 

Nick, it's Linux. I am booting from the emmc drive.


bolt:~ # lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
mmcblk0 179:0 0 29.1G 0 disk
├─mmcblk0p1 179:1 0 500M 0 part /boot/efi
├─mmcblk0p2 179:2 0 26.6G 0 part /
└─mmcblk0p3 179:3 0 2G 0 part [SWAP]
mmcblk0boot0 179:8 0 4M 1 disk
mmcblk0boot1 179:16 0 4M 1 disk
nvme0n1 259:0 0 931.5G 0 disk
└─nvme0n1p1 259:1 0 931.5G 0 part /mnt/1tb

 

Not sure what this means. Should I be looking for an option to reset?

 

The Reset Causes Handling has some flags that get set once a certain event happened, like if you suddenly loose power and it was not halted properly it will have set the Power Failure flag.
It can also be accessed by the eAPI demo applications from https://www.udoo.org/docs-gear/BIOS_UEFI_and_Tools/EAPI.html which runs under linux as well, though have not tried the linux applications yet.

 

So far, I've reset the BIOS to optimized defaults, power cycled the box and have not had any new issues. Fingers crossed this is day 4 with no issues. I was not able to go more than 2 days without finding the box powered off prior to this.
