"Hardware Error" after power failure (lemmy.world)

Hello,

Today my washing machine completely broke down. My parents desperately tried to get it working, but it resulted in the circuit breakers tripping and my server (an old Dell Wyse thin client) experiencing a hard power off.

When I tried to turn it back on, I received these errors on the screen.

I ran a memtest, and it completed without any issues. I also created a disk image backup just in case.

Is there any chance of getting this machine running again, or is it only fit for utilization?

All the red dots look like some kind of GPU failure. I think the TPM error is a symptom of a bigger hardware issue that is insurmountable.

A live cd or usb might help as others have stated.

That's weird. It's getting as far as Linux, so hopefully you have a backup you can restore and everything will be fine. If not, you can probably still pull your data off and reinstall.

Also, usually thin clients have eMMC chips instead of SSDs. Those are designed for low write lifetimes. I would be very cautious about trusting any important data to them, especially if you're not monitoring their health.

Unfortunately, I didn't have a backup, but I still managed to recover ALL the important files from this server, even with half of the file system sectors damaged. God, thank you. This is another lesson for the future to regularly make backups!

Really, so there was filesystem corruption? I'd definitely check the health of that eMMC chip if you can.

So, the flash memory wasn't built into the terminal, it was a 2.5-inch SSD drive that I yanked out of its plastic case to fit into the terminal's SATA slot.

Once unplugged it, I dumped the disk image using the dd command onto my computer, and then I worked on that image to recover the data.

From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
