|
| The hardware is a rebrand from clevo-computer.com - some minor
| spare parts can be had from there.
|
| The system is VERY prone to overheating, the fan is noisy. They
| claim the fan noise is "not annoying" which is only true in the
| short term. I have opened up the bottom shell and I believe the
| fan recirculates a bit of hot air back into the case. This really
| is a limiting factor for me, I'm considering an alternate cooling
| solution.
|
| The case had a minor chip in it within the first ten minutes out
| of the box (I don't know how that happened, I think it just
| pinged off by itself!). The palm-rests are starting to show dark
| spots. My barrel jack power connector is loose, I have to hold it
| in with a rubber band. (I still have the usb-c port) All the
| rubber feet at the bottom fell off quite some time ago,
| superglued them back on. The (super compact) PSU started to
| whine, that was replaced under warranty - but is stated to be a
| consumable item!
|
| Out of the box they have their own OS, which is a somewhat
| modified Ubuntu. My main driver is Debian and almost everything
| worked right out of the box - sometimes I got back (usb-boot) to
| their distro to validate things (see: support).
|
| The firmware is more than okay for me; I managed to cross-compile
| their "control centre" to allow me to change performance/fan
| characteristics on the fly. The uefi updates work fine (boot from
| a stick), but they are undocumented.
|
| The support is ... rigid. The first response is to boot their own
| distro and kernel. This is fair for a mass market product I
| guess, but I somehow hoped that specific questions would find
| their way proper Linux Gurus (tm).
