stucking of my PC HP EliteBook 840 G3

[jibrilarbicho]

Hello everyone, my PC is an HP EliteBook 840 G3 with a 6th generation Intel Core i5 processor. When the button light that I circled in the picture below becomes illuminated (when its color turns white), my PC automatically freezes, and it stops functioning. Could you please help me identify the problem and suggest how to fix it? OS is Ubuntu 22.04 lts

Apart from a few Workstations that come with Linux distro preloaded, HP provides no support for Linux.

I mention this because with Windows, we can provide links to videos and HP Documents. We can provide links to HP diagnostic apps you can download and run on your PC. We can provide links to HP drivers and to HP BIOS updates, which you can also download and run on your PC. And, nearly everything useful can be done using an application or utility that HP will provide you for free.

For the general population of HP customers trying to use or install Linux, we have NONE of that. No diagnostics. No videos. No downloadable utilities or tools. And, once you get into Linux, you discover that you have to become VERY familiar with the command line to do anything complicated. We have no command line scripts or examples to provide you.

So when I recommend going to the support forum for your Linux distro, it is because THERE is where you will get the amount and kind of support you need.
