Dynabooks are the absolute worst. I am trying my hardest to get rid of all of them. Our schools I think also procured them through COVID, But with budgets its difficult especially when some of them are "working" - I use that term loosely. I dunno about the rest of you, but Im seeing multiple failures across the board. Keyboards stop working. Webcam/Mic arrays stop functioning entirely and probably the most common one is they "forget" they have a trackpad and you have to go in and reinstall it. (only for another Windows Update to completely kill it again).
But on to your point as someone above mentioned these are usually NVME M.2 Drives so if you're wanting to repurpose them or erase them, physically removing them and doing it externally would be a much easier option.
