At one time, my computer lived not just under the table, with its face towards me, but behind it (i.e. behind its wall), and even behind the curtain (so that there was less noise at night :-)).
As you understand, turning on such a joy was quite stressful - you had to go around the table, sneak behind the curtain and only then, having first opened the case door (as you remember), gracefully pushing your hand somewhere there, still turn on the computer. Over time, natural laziness took over and I got tired of it, and therefore I just remembered a wonderful way to turn on the computer - from the keyboard (you press, for example, ctrl-esc and, voila, the computer turns on and you don’t have to reach for a button somewhere Power on the body).
How to configure this very on/off
This wonderful setting (I’m talking about turning on the computer by pressing buttons on the keyboard) lives in the section (I remind you that to get there you need to press the DEL button at the earliest stage of booting the computer, i.e. almost immediately after turning it on) Power - APM Configuration:
And it's called:
As you probably already realized, there is a small catch here, namely, it is important that your keyboard (or one of them) is connected to the connector PS/2(so round), not USB, - otherwise nothing will work.
If the keyboard is just like that, then feel free to set this setting to the position we need (i.e., choose between the items that indicate the buttons by which you can turn on the computer from the keyboard - Space Bar (space bar), Power Key (power button, there is a " extended" keyboards) or Ctrl-Esc) and, not forgetting to save the settings, turn off the computer in order to try out the innovation.
If BIOS Yours looks like this:
Then you need to go to the section Power Management Setup and set the setting there Power On by Keyboard:
In one of the positions available and necessary for you.
Voila, all that remains is to turn on your beloved iron friend with a deft movement of the hand without bending under the table and without slamming the case door, if you have one of course.
Afterword
So everything is simple and convenient.
By the way, quite a useful option for... pranks on inexperienced users :-)

Assembling a computer is not only about connecting large components of the system unit, such as a hard drive, video card, processor or power supply. During assembly, it is necessary to connect the case itself to the “insides” of the computer. Several important elements are displayed on the body. At a minimum, these are power and reset buttons, as well as a hard drive activity indicator. If we are talking about more advanced cases, then some connectors can be placed on the front panel, in particular, USB and inputs for headphones or a microphone. In this article, we will tell you how to connect the front panel of your computer so that all elements on it work correctly.
First, it should be noted that there should be several wires coming from the computer case. In common parlance they are called “pins” from the English word Pin, which means “Pin” or “Pin”. Computer case wires are tiny, and they are connectors into which plugs located on the computer's motherboard are inserted. 
Before you begin directly connecting the front panel of the computer to the motherboard, you need to decide which wire is responsible for which task. To do this, just look at the inscriptions on the connectors. The following symbols can be found on them:
The standard names are listed above. The connector responsible for USB can be labeled - USB 2.0 and USB 3.0. If they are both signed as USB, then it is easy to identify the connector from the faster data transfer protocol - it has more inputs.
Front panel of the computer: connecting the power and display buttons
There is nothing complicated about connecting the front buttons and indicators to the computer motherboard. To do this, you need:
Please note that the connectors and plugs are, in most cases, protected against incorrect connection. That is, it simply won’t be possible to connect them to each other incorrectly without breaking the contacts.
Front panel of the computer: connecting USB and 3.5 mm connectors
When connecting connectors on the front panel of the computer, you must follow the same rules: find the connection location in the instructions and then connect the plug to the connector. Please note that there may not always be space on the motherboard to connect the front USB 3.0 connector. If there is nowhere to turn it on, you will have to leave it unconnected.
It is worth noting that the connectors for connecting audio outputs can be included in a common block with a front display and power buttons, or they can be located separately on the motherboard. USB connectors are always located separately, and their connection location on the motherboard is labeled F_USB, JUSB or USB 3.0. The first two options are typical for the USB 2.0 connector, which is connected via 10 pins, while the 3.0 connector requires 20 pins. 
It is quite difficult to make a mistake in the process of connecting buttons, connectors and indications from the front panel. The main thing when performing this work is accuracy, since the connectors for the front connectors on the motherboard are very thin, and excess force can damage them.
Difficulty level: Easy
What you will need:
- Basic knowledge of English.
- Motherboard manual.
- Small screwdriver.
1 step
Turn off the computer's power. Remove the left side cover. Next you will see the hardware of your PC, for which you once paid a lot of money. At the bottom of the motherboard on the right, you will see connectors for connecting power wires, reboot wires and HDD indicators.
Step 2
In the vast majority of motherboards, these connectors consist of two rows of pins, usually 9 pins. Please note that each motherboard manufacturer has different pin layouts, so it would be better to look at the motherboard manual. The contact diagrams of the most common motherboards are shown in the figure (the contacts that need to be closed are indicated in red).
Step 3
Find the power cable (POWER two twisted wires) and carefully disconnect it from the motherboard. As a result of this you will see two pins. Connect the system unit to the network. Connect these two pins with a metal object, such as a small screwdriver. Don't be afraid, you won't get an electric shock, the voltage there is very low. After closing the contacts, the computer should start and boot. If this does not happen, then most likely you have closed the wrong contacts.
- Do not do this if the system unit is under warranty.
- Use this method only as a last resort; it is better to replace the case with a new one.
Manufacturers of modern system units are constantly modernizing the front panel. After the power and reboot buttons were moved to the front panel, audio and USB connectors moved next. But sometimes it happens that the computer's power button stops working, and the computer urgently needs to be turned on. Without a working power button, the system unit turns into a metal box that shows no signs of life. To revive the system unit, you can turn it on from the inside.
You will need
- System unit, instructions for the motherboard, screwdriver “+”.
Instructions
Hello friends.
Your hardware refuses to start by pressing Power, but you urgently need access to its contents? Or do you just want to know the cause of the breakdown? Then this short article is for you. I'll tell you how to turn on your computer without a button.
Before we begin, I want to make a disclaimer:
You perform all actions at your own peril and risk, I am not responsible!
I hope, you understood me. So let's go.
Algorithm of actions
First of all, you need to disassemble the system unit and find certain wires:
- Disconnect your computer from the power supply.
- Unscrew the left panel of the case and look at the motherboard, because it is the “brain center” of your hardware.
- You need to find wires of different colors running from the front of the case to the motherboard.
- On each one it is usually written what he is responsible for. You need "Power". As a rule, these are two intertwined wires.
On most computers, the connectors include 9 pins. Of these, the last two, consisting of 4 contacts and located in a short row, are responsible for switching on. They can be signed as Power Switch (PW Switch), Power ON, On-Off. This is what we need.
Now let's get started:
- The computer should start. If this doesn't happen, try again - maybe you didn't clamp it enough.
If the power button is out of order, as a temporary measure you can replace it with a reset button (a chip from the Reset button).
For laptop owners
Attention! Do everything as carefully as possible. If you doubt yourself, it is better to delegate this task to a more competent person.
Disassembling the laptop case is somewhat more difficult. To avoid causing trouble, look at the instructions specifically for your model. Once you get to the back of the power button, follow these two easy steps:
- Disconnect it from the cable or the wire going to it.
- Using a screwdriver, close the contacts on it, while holding the insulated end.
If the problem was in the button, then the laptop should start. That did not happen? Most likely, the problem is in the cable: there may be kinks or damage on it. In this case, you have no choice but to change the entire assembly completely.
Be that as it may, if the button does not work, you need to install a new one as soon as possible. You won’t start the computer every time with a pen or a screwdriver :).
By the way, if you are not sure that you will be able to do this using the methods described above, it is better not to try; especially when the hardware is still under warranty. After all, after you take it apart, the coupon is canceled, and under warranty there is a chance to fix the breakdown for free.
