Windows 95 - Windows Vista - Windows 7 - Ubuntu - Fedora - back to Ubuntu Think that’s it, can’t recall the years exactly The switch to Ubuntu was like in 2014 or something
I have one, the fan is active a bit too often and my battery became slightly bloated after 2 years of ownership. I did have it plugged in and didn’t use the plugged in battery mode, because I didn’t know about it, so maybe that was the issue. They did send me a new battery free of charge and I replaced it, so that was a good customer support experience. I general, I would recommend them.
