If your laptop computer freezes or slows down, the operating system is “clogged” with unnecessary modules and applications, or is blocked, the easiest way is to make a Hard Reset, reset to factory settings.
This article is dedicated to restoring factory settings on a laptop. We will tell you step by step how to do this, and in what situations Hard Reset is impossible.
When to restore the factory settings on the laptop does not work
Reinstalling the operating system on a laptop is the first reason that makes it difficult to reset user settings. Every second person after purchasing a laptop installs different software - most often Windows 7. The thing is that when you reinstall Windows 7 or 10, the partition on the hard drive is deleted, which is responsible for resetting the settings. This section is hidden and therefore deletion occurs unknowingly.But even if you call a professional computer specialist to replace the software, in 85% of cases a similar situation will occur. Computer technicians, service workers delete the partition either out of ignorance or because of the belief that the pirated version of the operating system is better, and therefore there is no need to reset the settings to the factory data.
If the OS was reinstalled on your laptop, you can search for a disk with the image of the partition that was deleted. Such a disk can most often be downloaded on pirated resources. There is also an official opportunity to buy a disc with a factory reset, this can be done on manufacturers' websites. Another option is to install a clean operating system on a laptop.
If the OS was not reinstalled after purchasing the laptop, Hard Reset is not so difficult to do, but only if you follow the instructions strictly. And you should know that the steps that will lead to the restoration of the factory settings will be different for different models of portable personal computers.
You should be prepared that after the reset procedure the following will happen:
- Delete all user information on "Drive C".
- Formatting the system partition and reinstalling the operating system without entering a key.
- The first launch of the system is accompanied by the installation of all proprietary applications and drivers.

Each Android device has a specific mode called Android Recovery. It is used to restore the correct operation of the phone. In it, you can reset all smartphone settings back to factory or originally set. In addition, this mode is used to flash the phone and obtain Root rights. How to enter the recovery menu on "Android", you will learn further from this article.
The methods of getting into the recovery depend on the brand and the specific model of your phone. First of all, it is advisable for you to rummage through the instructions or look for information about the exact model of your phone on the Internet. Here we will indicate a few relatively standard ways how to open the recovery menu for different devices. But first you need to do something else.
The first thing is reinsurance. Make backup
Backup - from English "back up" - this is the common name for the process of backing up data on your phone. Why do this? If something goes wrong and your data disappears, you can still restore it. And what could go wrong? Sometimes flashing the phone or opening access to root-rights, instead of improving the system’s functioning, on the contrary, “breaks” it. Therefore, if you are interested in how to enter the “recovery” menu in the recovery menu in order to upgrade it in the future, still first make a backup.
Most often, this option is hidden in the "General Settings" section. Most likely, you will see the words "Backup and reset." As you can see, if the phone is working properly, it is not necessary to enter the recovery menu to reset the settings. You can do this in normal mode.
How to enter the recovery menu on “Android”: basic button combinations
If you need a recovery mode, because your phone refuses to behave well, then, naturally, through the “Settings” we will not be able to reset the state to restore the system. Usually, in order to get into the recovery, the volume buttons and the power button are used.
Their combination depends on the model and brand of your phone. Most likely, you will simultaneously need to click the following:
- "Volume Up" and "Power";
- "Volume Down" and "Power";
- "Home" (button at the bottom of the screen) and "Power";
- both volume buttons, "Power" and "Home" (obviously, the creators of Samsung suggest a very masterful possession of the fingers from the owners of their devices).
What is Android Recovery?
After you enter the recovery, most likely you will see the picture that is shown in the photo.
This is an example of a standard recovery menu preinstalled on the device. Depending on the model, version of “Android” and the brand of your smartphone, it may look different. You will navigate through this list using the volume keys, and use the power button as a confirmation button. This list has the following functions:
Custom recovery menu
If you downloaded a special recovery menu to your phone, then it, unlike the predefined or “native” one, will be called custom. The main reason for the existence of alternative recovery menus is in the more advanced functionality of custom versions and various additional features, for example, in the installation of unofficial firmware.
The most popular custom menus are Clockwordmod Recovery and Team Win Recovery Project. If the first control is similar to the usual recovery menu - using the volume and power buttons, then when the second is working, the touchscreen remains active. As in the main mode, you control the process by touching the buttons on the screen (see photo below). This is undoubtedly convenient if the screen works without errors. If the “glitch”, because of which you need to go into the recovery, is in the screen, there will be difficulties.
USB debugging: how to enter the “Android” recovery menu from a computer?
In order for you to enter the phone’s recovery menu from your PC, do not be too lazy to find and download a special program on your computer that makes this possible. But before that, find the option "USB debugging" in the settings of your device - you will find it in the section for developers. Then download AdbRun to your PC. And already from it, knowing the commands for the console, you can control some functions of the recovery menu.
Now, if suddenly the recovery menu for Android does not open in the usual way on the phone itself, you can connect the device to the computer using a USB cable and control from there.
We leave beautifully: how to leave the menu
If you entered this mode out of curiosity, and now you are worried about how to exit the recovery menu on Android so that this does not lead to irreversible changes in your data, we will dispel your concern.
Most often, the exit is much easier to do than enter the menu. In most well-known recovery menus, this item will even be the first in the list - Reboot System Now ("Restart the system now"). If even this cannot be done, then you can cheat and do what all users usually do first of all, if the phone is “buggy”: restart using the power button, remove and reinsert the battery, or in the end just leave the phone discharged - subsequently it will turn back on in normal operation.
Working with the BIOS requires great care, as incorrect settings make the computer stop turning on or correctly detect connected equipment. You can reset BIOS settings using three proven reset methods on your PC and laptop.
Reset BIOS
If you can get to the interface of the basic input-output system, then there is a chance to reset the BIOS through the appropriate item in the "Exit" section. This is one of the simplest options that does not require opening the computer system unit. So, to restore the BIOS and return to the default settings, follow these steps:
This method works on a laptop and is suitable for a computer. After rebooting, the BIOS settings will be set to default. All changes made by the user after the purchase of the computer will be canceled.
Jumper Reset
The first method works if you have access to the BIOS. To reset the BIOS to the factory state, if you forget the password, you will have to disassemble the system unit and use the mechanical jumper, the change of position of which interrupts the current supply to the CMOS battery. The battery is responsible for storing BIOS settingstherefore, if you temporarily de-energize it or pull it out, the parameters will be reset to factory settings.
To finally discharge the remaining voltage, hold the system unit power button for 10-15 seconds. The computer is de-energized, so nothing will happen. Then return the jumper to its original position and assemble the system unit. Factory settings are set, now all parameters in the BIOS are set to default.
Removing the CMOS Battery
Speaking of the jumper, we already mentioned the CMOS battery, which is responsible for storing BIOS settings. Accordingly, if you remove it from the motherboard and then reinsert it, you can restore the parameters that were set by default. The algorithm of actions is the same as when using the jumper.
After resetting, insert the battery into place and assemble the system unit. After turning on the computer, there will no longer be any password on the BIOS, and all parameters will return to the factory state.
Reset on a laptop
If the system unit is easy to disassemble, then when resetting the BIOS on a laptop, you may encounter some difficulties. It’s good if you can enter the BIOS and restore the default settings by selecting the appropriate mode in the “Exit” section. If a password is set on BIOS, you will have to disassemble the laptop. Turn the laptop backside towards you. See if the laptop has a small hole labeled “CMOS”. 
If you find it, insert something sharp into the hole - for example, a paper clip. Hold for 30 seconds to reset the BIOS on the laptop. If there is no hole, you will have to remove the back cover and look for a CMOS battery or JCMOS pins on the motherboard.
- Disconnect the laptop from the network, disconnect the connected devices (mouse, speakers), remove the battery.
- Remove the back cover (on some models, it is enough to remove the protection of RAM and hard disk).
- Remove the RAM strips and hard drive.
Under the RAM strips there should be two pins that are signed as "JCMOS". They need to be closed with a screwdriver. 
Is the phone too slow, does it freeze when it starts up or doesn’t turn on at all? You must restore the system to factory settings. Resetting Android to factory settings is not as difficult as it might seem at the beginning, in this article we will describe in detail the entire process from A to Z.
Content:
Is the phone too slow, does it freeze when it starts up or doesn’t turn on at all? You must restore the system to factory settings. To go into Recovery mode, you need to turn off the phone, and then press the key combination. Each manufacturer has such combinations individually.
The most common is the simultaneous pressing of one - or two at once - buttons that control the volume level, and the "Power" key. The most popular companies use the following combinations:
- “LG” - “Power On” + “Volume Up”; after the logo appears, release and press this combination again;
- HTC, Nexus, Xiaomi– “Power On” + “Volume Down”;
- Lenovo and Motorola are both buttons for volume + Power On.
After loading Recovery mode, the user will see system lines with various names. Select the line "wipe_data / factory_reset" and confirm the selected action. The phone will perform an operation to reset new and restore old settings for some time. At the end of it, the gadget owner will only have to click the line “Reboot_System_Now”. The phone will turn off first, and then reboot with the restored Android system.
The phone must be turned on. To return to the factory settings of the android device, go to the general settings section. There we find the “Restore and Reset” item, where we select the “Reset Settings” action. After that, the system will warn the user about data deletion and ask you to confirm the operation. After completing the procedure, the phone will reboot and start the OS with the old settings.
The owner of the phone should go to the dialer menu and enter a code combination consisting of numbers and symbols. Manufacturers program their products differently, plus codes change over time. Therefore, for each specific model, especially not widespread, it is better to specify the code on the Internet.
However, there are some of the most popular combinations:
- *#*#7780#*#
- *2767*3855#
- *#*#7378423#*#*
After entering one of them, the system will return the phone to its original software state.
How not to lose data when resetting Android settings
Restoring the default settings involves losing all the data stored on the phone. All programs, documents, video and audio files, pictures, passwords and contacts are deleted by the system.
- Transfer data to a micro SD drive. If you purchased an external drive when you purchased your phone, you can copy all the necessary information to it using the file manager. In the absence of a card, it can be purchased immediately before returning the factory settings to the Android smartphone.
- Data from the phone can be saved by uploading it to the Google Drive app. In fact, this program is an analogue of the "cloud" storage. The user can download and store 5 GB of various information, and if you pay extra, this amount can be increased up to 1 TB. The application is installed from the Google Play market.
A little tip: In addition to saving data on a micro card, copy all the important information to the computer as well. In this case, even if something happens with the external drive, the necessary information will remain with you.
If the user of the Android device has forgotten the password that unlocks it, and no recovery methods have worked, you will have to resort to resetting the settings. This can be done, firstly, using the Recovery menu (the method is described at the beginning of the article).
Or here's another way to restore factory settings on an android gadget. So, the phone is on, but locked. When the system prompts you for a password, ask someone to call your number. During a call, the user has the opportunity to access the settings menu. Without accepting the call, you must go to this section and select “Reset All Data”. Confirm the operation. After restoring the initial settings, the password entry requirement will disappear.
This brand of phone is one of the most common, so it is worth mentioning separately. In particular, for Samsug gadgets, to exit to Recovery, you should press (simultaneously): “Turn on”, “Home” and the volume key “+”. The combination must be kept until the menu appears.
If a reset is made through the settings menu, select the "General Settings" section and go to the "Reset" item (it may also be called "Confidentiality", "Archiving and Reset"). In this paragraph, select the action "Data Reset" (or "Reset Device"). After confirmation, the phone will return the system to its original form.
Usually resetting the settings results in the need to re-enter the password for the Google account. Do not remember this data? There are several ways to solve the problem. The simplest is as follows.
After resetting the settings on your android phone, turn it on. We are connected to the Internet. When filling out your Google account, write and select any letters in the field of your email. A menu will appear above them, offering a choice of one of the actions: highlight, copy or send. Select "Submit." As the program that will do all this, indicate “SMS / MMS”. In the line of the addressee we indicate “112”, and in the message we enter a few any letters. After sending, the system will send an SMS that our letter has not been delivered. This is what is required. You should go into this sms-message and press the “Call” button, located near the recipient's number. This action should transfer the user to the contacts and dialing menu, where you need to delete “112” and dial the code: “* # * # 4636 # * # *”. The system will display a menu of several items. We choose the second (something related to statistics). This will move the user to the settings menu, where in the "Reset and Restore" item a new function will appear - data reset with the removal of the Google account.
Instruction manual
Make a backup. The fastest method for this is to connect the phone to the computer and synchronize the data on it with your account on the Google, Microsoft My Phone or Exchange ActiveSync websites. You can also save data in Outlook through ActiveSync. Another method is to use Spb Backup, Pim Backup or Sprite Backup to save data.
To return to the factory settings, use the phone menu. Press the following buttons in sequence: “Menu”, “Settings”, “Privacy”, “Reset to factory settings”, “Reset phone settings”, “Erase everything”. If you need to enter a phone code, you need to take it in the user manual. After that, the system rolls back the changes and reboots.
The second method, allowing you to return, is performed using the phone buttons. Turn off the phone and press two buttons at the same time: the call key and the end call key. While holding them, press the power key and hold all three buttons until a window appears with the question "Reset everything to factory settings?". Press the ringer key to accept or the end call key to cancel.
The next method is performed from the Recovery menu. To enter this menu, turn off the phone and press the Volume Up button and the Home button (middle button below the screen), and then the power key. After entering the recovery menu, select wipe data / factory reset, then press enter (that is, the call key). The mode when working in the recovery menu should be three-button.
Another way to reset to factory defaults is to use the service code. The service code itself can be found at http://vsekodi.ru/index.php/samsung. All settings are reset, even the internal memory card is cleared, so use this method with caution.
After the operation is completed, you can restore the data from the backup copy and configure the phone as you wish. Whatever method you choose, remember that returning the phone to the factory settings is a dangerous operation that can lead to data loss or even damage to the phone, so use it only in special cases.

Many do not understand why turn off the phone in an airplane. Each time, before takeoff, the crew of Russian airlines ask passengers to do this. But not all phones turn off the phones, and nothing bad happens. So is it really necessary and why?
In fact, if you recall better, the plane is asked to turn off not only phones, but also any other electronic devices. At one time, on-board systems of aircraft were not as high-tech as they are today, and technicians did not exclude the possibility of creating interference due to the operation of radio devices during the flight. Since then, the habit has remained of asking passengers to turn off the devices on the plane, at least during take-off and landing.
Now it’s almost certainly known that the pilots of the aircraft will not experience any control problems due to the fact that the included mobile phones will remain on board. However, the difficulty of transporting dozens or even hundreds of passengers by air is so high that airline employees try to stop even the smallest risks.
In practice, mobile devices can only interfere with the dynamics through which the crew commander addresses passengers. If the pilot’s voice suddenly disappears, it may well be due to a working phone. But this does not mean that there is a risk to the safety of the pilot. If, while on the plane, before taking off or landing, you saw that someone was sitting with the phone turned on, do not panic: nothing bad will happen.
