Introduction: Turn on the Laptop With the Lid Closed
I recently decided to connect my laptop to the monitor.
There was a small, yet annoying problem. I don't have a lot of space on my table, so I prefer to keep the laptop folded and perhaps even put something on top of it to utilize all the space available.
The problem with that is simple - you can't turn on the laptop with the lid/screen closed!
Yes, there are ways to wake up your laptop from the sleep with a keyboard, but that's not what I was looking for.
I like to turn off my laptop when not in use as well as the extension cord where it is plugged in. Because of that, the laptop can not be turned on with the keyboard.
This Instructable is for those people who have their laptops connected to the TV or a monitor - all the time.
We will have a look at a way to make an external power button for your laptop without doing any soldering.

It can be annoying that every time you want to turn on the laptop, you have to open the lid/screen.
Because of that, you have to keep your laptop in an acceptable place.
Even if you would have your hand as thin as a paper, you would not be able to turn on the laptop.
Reason for that - A magnetic switch
There is a magnet under the screen's bezel (frame) and a magnetic switch in the base.
When the lid is shut, the magnet is close enough to the switch to activate it.
The magnetic switch will prevent the laptop from turning on by the accident, so it's good for when you travel.
Because of that, there is no way to turn on the laptop, even if you could reach the power button with the lid closed.
First thing we have to do is take out the magnet, so the laptop would think that the screen is opened all the time.
Check your laptop's disassembly guide. Usually it's a simple procedure.
On my Acer laptop, I only had to unscrew 2 screws and I was able to open the frame.
Find the magnet and remove it.
Now your laptop will think that the lid is opened all the time even when it's closed.
If you would press the power button, the laptop would turn on.
But you don't have your hands as thin as the paper, do you? :)
Now we need to find a way to press the power button with the lid closed.
Get a balloon pump and attach a small tube to it.
I used heat-shrink tubing to secure the tube to the pump.
Attach a balloon on the other end of the tube.
Press the pump and make sure that the balloon does not stay inflated for too long.
The air should escape.
If it does not, loosen the zip tie or make a small hole in the balloon.
Now put the balloon on top of the power button and close the lid.
When you want to turn on the laptop, just squeeze the pump.
The balloon will inflate a little bit and press the button.
Now you can keep your laptop closed and out of the way.
