# Battery Status LED
|
|
Battery (low/critical) status indication by making a (the capslock) LED blink
|
|
|
|
## Prerequisites:
|
|
Make sure you have your laptop's ACPI module compiled into your kernel:
|
|
```
|
|
Device Drivers > X86 Platform Specific Device Drivers
|
|
```
|
|
|
|
For example: Asus laptop extras, ThinkPad ACPI Laptop Extras, etc.
|
|
|
|
## Usage:
|
|
Execute the script as a root user:
|
|
```
|
|
/usr/bin/battery_status_led.sh
|
|
```
|
|
|
|
Or start with systemd:
|
|
```
|
|
systemctl start battery_status_led
|
|
systemctl enable battery_status_led
|
|
```
|
|
|
|
The LED device can be changed by editing the systemd service file's line:
|
|
```
|
|
Environment="BATTERY_STATUS_LED_DEV=/sys/class/leds/input4\:\:capslock"
|
|
```
|
|
|
|
## Manual install on gentoo:
|
|
```
|
|
cd DIR
|
|
git clone https://github.com/dmatetelki/battery_status_led
|
|
cd /usr/local/portage/app-misc/
|
|
ln -s DIR/battery_status_led/app-misc/battery_status_led battery_status_led
|
|
ebuild battery_status_led-0.1.ebuild digest
|
|
emerge battery_status_led
|
|
```
|

|
|
```
|
|
cd DIR
|
|
git clone https://github.com/dmatetelki/battery_status_led
|
|
cd battery_status_led/debian
|
|
./package.deb
|
|
sudo dpkg -i ./batterystatusled_0.1-1.deb
|

|
|
## Note:
|
|
Did you know that the CapsLock key can be turned into another Ctrl?
|
|
Add the following lines to `~/.Xmodmap` :
|
|
```
|
|
remove Lock = Caps_Lock
|
|
keycode 0x42 = Control_L
|
|
add Control = Control_L
|
|
```
