I am very good with all Debian and Ubuntu Linux Distributions (Chrome OS, self-developed and managed OSes Debian 8, Debian 9, Debian 10, Debian Bullseye, Ubuntu 18.04-3 LTS, Ubuntu 19.04, Ubuntu 20.04, Cinnamon Desktop (Debian and Ubuntu WM), KDE WM, XFCE WM, KUbuntu, XUbuntu, GNOME, etc.)
Respuesta a "How can I reset a managed chrome book back to factory"Ideally, assuming that this Chromebook has Enterprise Origin enabled, (meaning your Chromebook is locked down by an administrator and has probably disabled access to the TTY terminal, Crosh shell, and others) you can choose to purchase a new motherboard, with new RAM chips and memory, for that particular model. This will reset the Chromebook as a different model number, therefore all the memory and such will not be on the hard drive, but on Google Drive when you sign in.
Respuesta a "Battery percentage suddenly drops from ~60% to 7%"The chances are, you simply need a new battery. You can get one (I hope you know your serial number) from https://support.apple.com/13inch-macbookpro-battery-replacement in order to purchase one directly from Apple.
Respuesta a "I can't hear any sound. What could be causing this?"In most circumstances that involve Chromebook speaker issues (especially in Chromebooks, as they tend to be weak) the problem with them is that water has gotten into them or they have been tampered with. If this is the case, you should buy a new set of speakers. The other possibility: If you have taken your Chromebook apart before, you may have forgotten to plug your speakers back in or plugged them in the wrong area. It depends on what Chromebook brand and model you are using, however. Then again, it may be something as simple as you have blown them out by playing heavy metal too loud.
Respuesta a "Formatted internal storage, no boot AT ALL"Ideally, you can reinstall the GRUB/GNU boot firmware from a simple file. If you want to install the bootloader, go to http://ftp.nl.debian.org/debian/dists/te...-amd64/current/images/netboot/ and click on the mini.iso file. I believe this is the bootloader file.
