## Prevent suspend when lid closed

Add a new file:

```sh
nvim /etc/systemd/logind.conf.d/no-suspend-on-lid.conf
```

Add this:

```
[Login]
HandleLidSwitch=ignore
HandleLidSwitchExternalPower=ignore
HandleLidSwitchDocked=ignore
```

```sh
systemctl restart systemd-logind
```

## Wake-on-lan

See my network interfaces:

```sh
ip link show
```

```
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: enp1s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP mode DEFAULT group default qlen 1000
    link/ether 54:e1:ad:9d:a8:74 brd ff:ff:ff:ff:ff:ff
3: wlp2s0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue state DOWN mode DORMANT group default qlen 1000
    link/ether 52:37:c4:2c:79:38 brd ff:ff:ff:ff:ff:ff permaddr 3c:f8:62:b3:7f:81
```

Enable for the ethernet

```sh
ethtool -s enp1s0 wol g
```

Make it pemanent. Create a systemd unit:

```sh
nvim /etc/systemd/system/wol.service
```

```
[Unit]
Description=Wake-on-LAN
Requires=network.target
After=network.target

[Service]
ExecStart=/usr/sbin/ethtool -s enp1s0 wol g
Type=oneshot

[Install]
WantedBy=multi-user.target
```

```sh
systemctl enable wol.service
```

Check it:

```sh
systemctl start wol.service
systemctl status wol.service
```

Suspend the laptop:

```sh
systemctl suspend
```

Wake it up again from another machine:

```sh
wakeonlan 54:e1:ad:9d:a8:74
```
