A nice laptop which comes in many different versions in terms of CPU, RAM, HDD and graphics, with or without pre-installed Windows (non-Windows versions have FreeDOS installed).
Archlinux boot medium boots with Secure Boot enabled if no Windows installed. Otherwise, it's necessary to disable Secure Boot, which is possible after selecting
UEFI only option on the Boot tab - a
Secure Boot option appears then on the
Security tab in the setup.
It works without problems with a systemd built-in bootloader - for GPT partitions and UEFI in non-Legacy mode GRUB is not needed (although it's possible to use it), the systemd bootloader displays a boot menu where you can choose Windows if dual booting.
No problems with brightness adjustment and with the touchpad (after installing Synaptics drivers from repo), as well as with networking.
In an Intel+ATI version of graphics the Intel adapter is active by default, the ATI one is detected. I haven't tried yet to make switching possible.
When an extra HDD installed instead of the optical drive, it gets detected but it is not going to work (
SATA link down message in dmesg). The solution is to add a line forcing 1.5 Gbps transfer instead of 6 Gbps to the kernel boot parameters (how to do it depends on the bootloader).
It's difficult to separate the front bezel from the optical drive e.g. when you want to replace it with a caddy for a hard drive. I do not recommend opening it's case when you think it may help. You are risking making a mess in the tray opening mechanism, you may lose small parts easily or have no idea how to assemble it back. And it does not help at all. Just pull the bezel with a bit of force (yes, you may break the latches, but I can't see any other option).
