Is it possible to switch on my laptop without opening the lid?

I have ordered an Acer Swift 1 (SF114-32) laptop 2 days ago, Arch Linux installed. In fact this is first laptop, I used a desktop PC till now. I would like to use it like a PC, and I want to attend to it, because maybe later I will give it as a present, or simply sell it. I don't want to get crumbs and dust into the keyboard for example. Is it possible somehow to switch it on, and use it all day without opening the lid? Of course I have USB keyboard, mouse, and external monitor with HDMI port.

I would like to turn on the laptop let's say via a keypress, or key combo from a USB keyboard. Or for example by a special device which connects to the USB 3.1 type C port, called docker or docking station. Or by a special device which uses the "wake on lan / wlan" technology by a USB connected ethernet plug. I have the AX88772B network controller device, USB to RJ45 adapter, which supports wake on lan, according to its data sheet. When I searched the internet I found this funny method too https://www.youtube.com/watch?v=LSsqOQH4LQQ However I would like to use a regular switcher device with a button if other methods doesn't work, eg.: https://www.norwegiancreations.com/2015 … ed-button/

I have already tried out switching on at a given time, called RTC wake-up, following this post https://bbs.archlinux.org/viewtopic.php?id=55048 and it worked without a hitch.

"Wake" in "wake on lan" is not the same as powering on - it's just waking from sleep/suspend.  If that's all you want to do, then your usb keyboard should work fine.  There is often a key combination for sleep/wake on keyboards, or on some you just press a "Fn" key.

Not really, I meant waking up from S5 state, which is the complete power off.

Re: Is it possible to switch on my laptop without opening the lid?

For example when I use the "evtest" command, I can see this.

sudo evtest /dev/input/event2
Input driver version is 1.0.1
Input device ID: bus 0x19 vendor 0x0 product 0x1 version 0x0
Input device name: "Power Button"
Supported events:
  Event type 0 (EV_SYN)
  Event type 1 (EV_KEY)
    Event code 116 (KEY_POWER)
Properties:
Testing ... (interrupt to exit)

But when I press the power button, I can't see any keycode printed onto the screen. Same with the "showkey" program, I get no visible keycode when pressing the power on button.


When I querying another event source (the keyboard in fact), then I can thee the KEY_POWER (keycode 116) among the supported events (however my current keyboard doesn't have a dedicated power on button):

sudo evtest /dev/input/event3
Input driver version is 1.0.1
Input device ID: bus 0x11 vendor 0x1 product 0x1 version 0xab41
Input device name: "AT Translated Set 2 keyboard"
