Reason: Stub (Discuss in Talk:HASEE K650D i7 D3#)

The HASEE K650D-i7-D3 is a powerful laptop, on which Arch Linux runs fine. For a lightweight window manager, some additional configuration should be setup.

## Touchpad synaptics

xf86-input-synaptics should be installed for a lightweight window manager (but not Gnome or KDE). In some cases, addition configuration is necessary for single-click, double-click and middle-click:

    /etc/X11/xorg.conf.d/70-synaptics.conf

    Section "InputClass"
        Identifier "touchpad"
        Driver "synaptics"
        MatchIsTouchpad "on"
            Option "TapButton1" "1"
            Option "TapButton2" "3"
            Option "TapButton3" "2"
    EndSection

For details, see Touchpad Synaptics.

## Backlight

Hot keys for backlight might not work after installation of Arch Linux, so xorg-xbacklight is necessary for backlight configuration. See Backlight#xbacklight.

## Video cards

Install bumblebee along with Nvidia and Intel drivers. nvidia-dkms is recommended for auto configuration after kernel updates. Acceleration mode of the Intel video card should be changed to "uxa", according to Intel graphics#AccelMethod, so that firefox will not fail to scroll smoothly, and 3D games will run normally.

## Audio

After regular sound check, additional configuration should be conducted. Run `aplay -l` to find default build-in Audio Analog Stereo. In current machine, you can find the card ID with 1 and the device ID with 0. Then following configuration file can be created as following:

    ~/.asoundrc

    defaults.pcm.card 1
    defaults.pcm.device 0
    defaults.ctl.card 1

After that, run `alsamixer` to unmute.

## Webcam

The webcam works out of the box. In order to test the device, see Webcam setup#Applications.

## Software access point

A Wi-Fi access point can be created in this computer following Software access point. However, WPA/WPA2 will not work properly in channel 1 ~ 9, so channel must be set at 10 or more in the configuration:

    /etc/hostapd/hostapd.conf

    channel=10
