I work most of the time with my Windows 10 laptop (Lenovo X1 Carbon, 2012 1. gen model) closed and an external monitor attached.
To achieve this J'ai to start the computer by
- opening the lid,
- press the start button,
- wait until it booted and
- the external monitor is active, then
- [close the lid which puts the laptop into sleep after which](https://superuser.com/a/1255467/25933)
- [I can hit a mouse button or key to make it "start" (unsleep) again](https://superuser.com/a/1255467/25933)
Of course this is a bit silly.
On the other hand J'ai aussi work mobile, with no external monitor. One thing I can not compromise on is that the laptop indeed has to go into sleep when I close the lid (~ 15 years of conditioning).
Existe-t-il un better way to turn my laptop on if an external monitor is attached?

**EDIT**:
## Wake-On-Mouse
- [Change what closing the lid does](https://support.microsoft.com/en-ph/help/13770/windows-shut-down-sleep-) by setting it to 'Do Nothing':
- Hit the ⊞ Win key and type `lid`, *or else go*:
- `Control Panel → Hardware & Sound → Power Options → System Settings`
- Plug in an external mouse.
- Allez dans `Device Manager` or hit ⊞ Win + X followed by M
- Double-cliquez sur the external **USB pointing device**.
- On the **Power Management** tab, ensure that `Allow device to wake computer` is checked.
- When you're finished using the built-in screen, [cycle through projector options to enable monitor](https://www.pcworld.com/article/191359/Easily_Switch_Between_External_Displays_in_Windows_7.html) with:
⊞ Win + P
- Don't use `Shut Down` when finished with the computer. Instead use one of:
- `Hibernate` shortcut: ⊞ Win + X followed by U then H
- `Sleep` or use ⊞ Win + X followed by U then S
Now vous pouvez keep the screen lid closed but turn on and use the laptop with an external monitor. To meet your last 'requirement', vous pouvez change the settings to Sleep settings so the laptop goes to sleep after a set amount of idle time:
- ⊞ Win and then type: *sleep* + Enter
- `Control Panel → Screen → Power & Sleep`
Now you don't need to use the power button to turn it on *or* off.
## Some other options:
- You could have the laptop just stay on *all the time* (regardless of the lid) by following only `Step 1` (above).
- You could also [schedule the laptop to startup (or shutdown) at the same time(s) every day](https://www.howtogeek.com/204742/how-to-make-any-computer-boot-up-or-shut-down-on-a-schedule/0).
- Si vous êtes handy with tools and electronics you could also achieve this by modifying either:
- the [laptop access to the power button](https://youtu.be/z10punCb0v0), or
- laptop lid so it's functionality is [more like a desktop machine](http://www.instructables.com/id/Convert-a-laptop-with-a-broken-screen-into-a-quiet/).
- You could get a [docking station](https://www.insight.com/en_US/buy/product/40A90090US/LENOVO/40A90090US/Lenovo-ThinkPad-USBC-Dock--docking-station/) or [USB Hub](https://forums.lenovo.com/t5/ThinkPad-X-Series-Laptops/X1-Carbon-2014-USB-Hub-wake-up/td-p/1512104), with [WOL](https://en.wikipedia.org/wiki/Wake-on-LAN#Magic_packet) so either:
- an external device can [wake it with a WOL Signal](https://support.lenovo.com/ca/en/solutions/ht073996)
- plugging the laptop into the dock will wake the laptop if a network is present
- WOL is disabled par défaut so you'll have to [enable it in BIOS](http://superuser.com/questions/100083/how-to-turn-on-wake-up-a-laptop-without-opening-the-lid).
Since I'm new here I wasn't allow to includes my list of sources and examples, so I will try to post them in a separate comment or answer.
