Hardware is a 4820TG/5820TG, but should be similar for all these laptops.

## ACPI

ACPI works with BIOS v1.18 and higher.

BIOS v1.19 for 4820tg

BIOS v1.19 for 3820tg

If you do not have Windows installed, you can flash with a FreeDOS thumb drive.

## Bluetooth

On some machines, Bluetooth cannot turn on because of `Fn`+`F3` switching only WLAN. Fixed DSDT table seems to solve the problem.

On the 3820TG, Bluetooth might not work even if `Fn`+`F3` is used to turn it on. (Symptoms include "usb disconnect" messages in dmesg, and the adapter not showing up in hcitool dev.) In this case, copying `/lib/firmware/ath3k-2.fw` to `/lib/firmware/ath3k-1.fw` helps, see this mailing list thread. If it does not work for you, please change this note!

For some models of 4820TG, Bluetooth can be turned on with acer_wmi driver. To check that the driver is installed:

    lsmod | grep acer_wmi

To check bluetooth state (1 is on, 0 is off):

    cat /sys/devices/platform/acer-wmi/rfkill/rfkill2/{name,state}

    acer-bluetooth
    0

To turn on bluetooth:

    echo -n 1 > /sys/devices/platform/acer-wmi/rfkill/rfkill2/state

## Wireless (TimelineX 5820)

Wi-Fi driver needs to be installed. Open source brcm80211 driver causes kernel panics; the proprietary broadcom-wl driver works fine.

## Wireless (TimelineX 4820TG)

Wi-Fi driver does not work by default. You need to install broadcom-wl and b43-firmwareAUR. See Broadcom wireless for details.

## Display brightness control

Sometimes brightness control for integrated card does not work (at least with the 2.6.36.2-1 kernel). You may add `acpi_osi=Linux` to the kernel line in the GRUB config to fix this.
