How to turn on a laptop using the keyboard?

Using the Boot Menu

To begin with, we will tell you about the simplest way to solve the problem, gradually moving on to more complex techniques. When the power button stops working, it is best to take the laptop to a service center for repairs. If you urgently need to start your computer, then use the Boot Menu

. The main purpose of the menu is to select the operating system boot device. The user can install the file on the hard drive, external drive or disk.

Inspect the laptop case. In addition to the main power button, there may be a small additional button to launch the BIOS. It is intended for emergency situations, such as, for example, a non-functional starting mechanism for a laptop computer. Most often it is located with the power connector (the connector for connecting the charger cord) or directly next to the Power

. Again, depending on the model of the device, the method of pressing it also depends, but, as a rule, a pencil or pen is used for this purpose. On Acer models it is often located here.

On Lenovo, on the side or on top, under the keyboard; in different models, the location of the emergency power button may be different.

It should be said right away that it is not available on Samsung and Dell.

When you find an emergency BIOS settings switch on the case, of course, you need to press it. Then wait until the laptop turns on and starts the settings. The further procedure is just as simple: in the blue window that loads, you need to select Normal Startup

and press the Enter key on your keyboard.

After this, the operating system will boot in normal mode. True, it will be inconvenient to use this technique every time. If you cannot quickly repair your laptop, set Windows to go to sleep.

How to turn on a laptop without a power button from the keyboard - a proven method

Greetings, dear readers! A common problem in laptops is the power button stops working. It blinks, does not turn on, does not respond to pressure. It is not always possible to take the device to the service center immediately after identifying a breakdown. There are several ways to turn on a laptop without the power button from the keyboard. Our article will tell you about each of them in detail.

The easiest way is Boot Menu

The problem with the power button is a common problem with laptops. The key is stuck, does not respond to pressing for a long time, after turning it on it immediately goes out and blinks. There are many reasons why the button broke. Our task is to start the device without it.

To start the laptop, use the boot menu. Its main purpose is the ability to select a device for loading Windows. A file on a hard drive, a flash drive, or a disk can be used. To enter the boot menu on laptops there is a hardware button.

You can find it on models from the following manufacturers:

• sony;
• lenovo;
• asus;
• acer;
• hp.

The location varies depending on the model. On some it is located on the side, on others it is under the keyboard, above it.

On Samsung, Dell, Desp there is no button.

Switching algorithm:

• look through the body of the device and look for the button. If you don't find it, read the instructions. what if they missed it;
• press the button. If it is hidden in the case, use a pin or needle to press it. One click is enough;
• A small blue window will appear. Select the normal operating mode - normal startup, click enter.

The laptop will start. It is inconvenient to follow the described procedure each time. It’s better not to turn off the laptop, but to configure Windows to go into sleep mode and the ability to exit it.

There are several ways to enable sleep mode:

• press “start”, then “sleep”;
• go to PC settings, click “systems”, select “power and sleep mode”, determine the time when the inactive laptop falls asleep;
• go to the control panel, where you find “power supply”, set the sleep mode settings.

To turn off sleep mode, use the mouse or any keyboard key.

Setting up the output via the keyboard is as follows:

• open device manager;
• select the “keyboard” menu item;
• right-click and select “properties”;
• go to “power management”;
• O;
• right-click to go to properties;
• select “power management”;
• Grant permission to turn off standby mode.

Another option is Power ON function

The next method requires changing the settings in the bios.

To enter the BIOS press F2 or del. These keys work on most laptops, netbooks, including Asus. On Lenovo and Acer f1 can be used, on Sony - esc+f2.

But these keys are useless if the laptop does not turn on.

In this case, enter the BIOS like this:

• press the hardware button;
• included in the boot menu;
• select bios setup.

Further:

• find the menu item power (power management setup);
• go to power settings - power on (power on by ps2 kb/ms);
• indicate how the laptop should turn on. If you select “any key”, activation will be performed using any key. When you press the “hot key”, any key combination is selected. The option is not available on all PCs;
• press f10, save and exit.

After rebooting, the laptop can be started by pressing the hotkeys specified in the BIOS.

The most difficult method is to run from the motherboard

Setting up a login to a laptop with a non-working power key through the BIOS is an easy-to-set up method that is convenient for further use. The only drawback is that to use it, you must first log into your laptop. A hardware button is used for this. If it is missing, it starts from the motherboard.

Setting up sleep mode

You will need to enable the ability to activate sleep mode if it was previously deactivated. This mode is designed to maximize energy savings. It is especially useful if you have to be away from your laptop for a long time, but you don’t want to turn it off or simply forget to do so.

First of all, look carefully at the designations of the laptop keyboard keys. You can find a crescent moon symbol, which indicates the ability to activate sleep mode by pressing this very button.

To exit the mode, just press one of the keys or click the computer mouse button. To configure automatic activation of the mode, go to the Windows Control Panel, then the “ Power Options”

" and "
Changing scheme parameters
".

Next, we set the time period after which the laptop will go into sleep mode. If the device is running on network power, then instead of “ Never

» set a specific time. Finally, do not forget to save your settings.

Closing contacts on the motherboard

Now a difficult way to solve the problem is to close the contacts of the power key. The Power mechanism is designed to close contacts that transmit an impulse to turn on the computer. This means that when the button does not function for any reason, you can close the contacts yourself. To do this, you will need any conductive object, such as a screwdriver.

You take further actions at your own peril and risk. If the laptop is under warranty, of course, there is no need to disassemble it and try to fix it yourself. Immediately go to the store where you purchased it to resolve the problem. Similar actions can be taken by owners of older devices whose warranty period has long expired. But even in this case, there is a small nuance: careless actions can easily damage expensive boards and aggravate the breakdown. The cost of subsequent repairs will be many times greater than replacing one faulty Power button.

If you are confident in your own abilities, then the procedure is as follows:

1. Disconnect the laptop from the network;
2. We take out the battery and disassemble the case;
3. We remove the bottom panel: unscrew all the bolts, if necessary, use a plastic card to pry up the joint of the parts, and then draw around the perimeter;
4. Unsnap all the latches;
5. We find a connector on the motherboard to which the power button is connected via a cable;
6. Now you need to determine a pair of contacts PWR and Ground (case), when closed, the device will turn on. This will most likely have to be done experimentally, because... There are a huge variety of motherboards for laptops, and finding a circuit diagram for a specific model can be problematic.

Closing the button contacts

Perhaps the next method will be simpler. You can close the contacts not only on the motherboard connector, but also on the power button itself, even if it does not work.

Moreover, this is easy to do on models in which to access the power button you just need to remove the cover on the front panel above the keyboard.

The work is also not easy, but somewhat easier than disassembling the laptop to its core.

If the laptop does not react in any way to closing the contacts, most likely the problem lies elsewhere. Be sure to check the battery. She could have discharged. Check the power cable as well as the unit itself. You can never rule out the possibility of failure of the motherboard or processor. If there is a power surge in the network, after which the laptop stops turning on from the button, you should contact the service center so as not to waste time.

How to turn on a laptop without a power button: 4 ways

Sometimes it happens that in the evening I turn off my laptop and go to bed. And in the morning you press and press the button, but to no avail: the machine is silent.

Of course, it is advisable to contact customer service to have the button repaired. But if you need a nosebleed to start your laptop, you can use several emergency methods.

Alternative methods for turning on a laptop

First, make sure that the treasured button is completely broken or only the upper part is damaged. If the switch itself is fine, and the problem is in the piece of plastic on top, try pressing the button with a pencil or other object. Doesn't turn on? Then we move on to other options:

• via boot menu;
• key combination;
• via BIOS;
• sleeping mode.

Using the Boot Menu

If the power button does not respond to pressing, you can access the boot menu. Carefully inspect the laptop for a hardware button. Typically this round depression is present in the following models:

• Sony;
• Lenovo;
• Asus;
• Acer;
• HP.

Look for it near the power key. Also look under the keyboard and on the sides of the case.

@forumscdn.lenovo.com

As a last resort, check the instruction manual to find out its location.

If you have a laptop from Samsung, Dell or DEXP, you don’t have to waste time. These models are not equipped with such a device.

1. Press the Boot Menu once using a pin, needle or toothpick.
2. In the blue window that appears, select Normal startup mode.
3. Click Enter.

Wait for the operating system to load. You can work. But in the near future, still take your device for repair.

Using the keys

In order not to suffer with the Boot Menu next time, you can go into the BIOS through it and set any key to turn on the laptop. For this:

1. After loading the BIOS, enter the Power Management Setup or “Power” section (different models vary).
2. Click on Power on Function or Power On by PS2 KB/MS.
3. Select Any Key (one key to enable). By selecting Hot Key, you can set any combination of buttons.
4. Press F10, confirming the changes with Enter.
5. Reboot your laptop to save the settings.

Now, to turn on your compact computer, you just need to use one or two keyboard buttons that you set in the BIOS.

Putting into sleep mode

During a breakdown, so as not to have to worry about turning it on every time, you can simply leave the laptop on. Put it into sleep mode when not in use. And when necessary, press any key or move the mouse, and the system will immediately “wake up”.

Proceed in the following order:

1. Open “Start” > “Control Panel” > “Power Options”.
2. In the left column, select “Set sleep mode settings.”
3. Opposite the line “Put the computer into sleep mode”, set the time twice, for example, 5 minutes. when operating on battery or mains power.
4. Click on “Save Changes”.

Now you have to configure the conditions for exiting sleep mode.

1. Click “Start” > “Control Panel” > “Device Manager”.
2. Right-click on the word “Keyboard” and select “Properties”.
3. Go to the Power Options menu.
4. Check the box next to “Allow this device to wake the computer from standby mode.”

Now you can return your laptop to work from sleep by pressing any button on the keyboard. In approximately the same way, you can configure the output from the sleep state using the mouse.

Closing contacts

If the hardware login button is completely missing on your device, you can try shorting the contacts. To do this you will have to perform partial disassembly.

If the laptop is under warranty, it is better not to resort to this method.

The essence of your actions will be as follows: you need to disconnect the broken button and connect the PWR and Ground contacts bypassing it.

How to disassemble your particular laptop, see the documentation. After all, the models are very different from each other. Usually it is enough to remove the protective cover near the keyboard, prying it with something thin, and you will gain access to the treasured button. Try closing the contacts using a screwdriver on the board itself. Or you can, by disconnecting the cable from the motherboard, do the same there.

There is a third option: take the cable out of the case. The next time you need to work, close the contacts.

Don't rush to mess with your laptop. First, make sure that the problem of not turning on is really a broken button. After all, the laptop may not work for other reasons. Eg:

• the battery is dead;
• the power cable is damaged;
• the power adapter is broken;
• the processor crashed;
• motherboard is faulty, etc.

Only after discarding all other options and making sure that the power key is faulty, proceed to closing the contacts.

So now you know what to do in case of an emergency involving your laptop. First of all, use the hardware button, and if it is missing, remove the panel and close the contacts. But after that, take the smart assistant to a service center as soon as possible and have it repaired.
