Reset BIOS settings on CLR CMOS computer. BIOS reset to factory settings - algorithm. What is bios

A large number of diverse settings are available to the user who relate to the computer. Therefore, with their inactive use, the computer can start working not stably or do not start at all. In this case, you need to reset the BIOS to the factory settings. In this material, we will tell about how to reset the BIOS settings to factory and thereby correct the unstable computer.

Reset BIOS settings via BIOS Setup

The easiest and safest way to reset the BIOS settings to the factory is used by the special option in the BIOS settings themselves, that is, in the BIOS Setup. In any version of the BIOS, there is always an option that allows you to return the factory settings, it is necessary to simply activate, confirm the reset and exit the settings while saving changes. After rebooting the computer, it will start working on factory settings.

Using this method, you do not risk damaging the computer, so it needs to be used in all cases where it is possible. The remaining relief options are associated with some risk and with incorrect execution, you can damage something. Therefore, they are only for emergency cases when the computer does not turn on.

Therefore, if your computer is loaded and you have the opportunity to enter the BIOS, then you must reset the settings through the BIOS Setup interface. To do this, find the menu item that resets the BIOS settings to the standard. Usually, this item is in the "EXIT" section and is called "Load Setup Defaults" (Download Standard Settings).

For example, in the case of Phoenixbios, you need to open the "EXIT" section and select "Load Setup Defaults"

And then get out of the BIOS with saving the settings by selecting the "Exit Saving Changes" item and clicking on the "Yes button".

In some BIOS versions there are two options to restore standard settings. For example, in the screenshot below, you can select "Load Fail-Safe Defaults" and "Load Optimized Defaults". Both of these options work in the same way, they load standard settings. Only the first option loads a safer profile with which the computer should work in any case, and the second option loads the profile with optimal settings.

On modern motherboards with UEFI BIOS, there is also an option that allows you to return the standard settings. But, due to the bright and non-standard interface, it may be more difficult to find it. For example, in the screenshot below the UEFI is shown from ASUS. Here, to return to the standard settings, you need to click on the "Default" button at the bottom of the screen or click F5. After that, you need to exit using the option "Save & Exit" (Save and Exit) or Press F10.

Also on this board from ASUS, you can first go to advanced settings by clicking on "Advanced Mode" or pressing F7. After that, you will need to go to the "Exit" section, activate the "Load Optimized Defaults" option and exit using the "Save Changes & Reset" option.

There are many different versions of BIOS and UEFI, so your interface will be different. But, in general, the procedure for resetting settings is always very similar and should not cause problems with you.

Reset BIOS settings with jumpers

If the computer does not boot or you do not have access to the BIOS, you can reset the settings using a special jumper on the motherboard. Such a jumper is on any board, but it can be located in different places and can be signed differently. For example, it may be called CLRTC, CLR_CMOS, JCMOS, RESET CMOS, CCMOS, CONFIG, BIOS CONFIG etc. Therefore, if you do not have enough experience, it is better to first get acquainted with the instructions from the motherboard. Such an instruction should go complete with a board, and you can also download it for free on the fee page from the manufacturer's official website.

In order to reset the BIOS settings using a jumper, you must turn off the computer and de-energize it. After that, remove the side cover of the system unit and find the jumper on the motherboard. To reset the jumper must be rearranged to another position for a few seconds and then return it back. If the contacts for reset only 2 and the jumper is missing, then these contacts you just need to close for a few seconds.

In addition, a special button can be installed on some expensive. This button can be placed directly on the board either can be rendered on the back side of the computer, on the panel with ports.

If there is such a button to reset the settings, it is easy to turn off the computer and click on it for a few seconds.

Reset BIOS settings using a battery

If you are not sure that you found the desired jumper, you can simply turn off the battery on the motherboard. Disconnecting it for just a few seconds, you reset the settings and return the BIOS to the factory settings. This option is quite simple and works anyway.

In order to disable the battery, as in the previous way, you must first turn off the computer and de-energize it. After that, remove the side lid and find the battery on the motherboard. This is a small battery of type CR2032, as a rule, it is closer to its lower part.

Next, you need to remove the battery with a screwdriver, wait a few seconds and set back. It is necessary to do as much as possible in order not to damage the motherboard. If the screwdriver jumps out from the battery, then you can knock down the small components on the board, which will inevitably turn into the need to repair.

In some cases, the BIOS work and the entire computer can be suspended due to incorrect settings. To resume the performance of the entire system, you will need to reset all settings to factory. Fortunately, in any machine, this function is provided by default, however, the discharge methods may differ.

In most cases, experienced PC users can return the BIOS settings to an acceptable state without fully reset. However, sometimes still have to make a complete reset, for example, in these cases:

• You forgot your password from the operating system and / or BIOS. If in the first case, everything can be corrected by reinstalling the system or special utilities for recovery / reset the password, then in the second will have to do only to reset all settings;
• If neither bios nor the OS is loaded or loaded incorrectly. It is likely that the problem will be deeper than incorrect settings, but try to make a reset worth;
• Provided that you contributed incorrect settings to BIOS and cannot return to the old one.

Method 1: Special utility

If you have installed a 32-bit version of Windows, you can use a special built-in utility that is designed to reset the BIOS settings. However, this is provided that the operating system starts and works without problems.

Use this step-by-step instruction:

This method is suitable only for 32-bit versions of Windows, besides, it is not distinguished by stability, so it is recommended only to apply it in exceptional cases.

Method 2: CMOS Battery

This battery is available almost on all modern motherboards. With it, all changes in the BIOS are stored. Thanks to her, the settings are not reset every time you turn off the computer. However, if you get it for a while, then there will be a reset to the factory settings.

Some users may not get to get a battery due to the characteristics of the motherboard, in which case there will be some other ways.

Step-by-step instructions for dismantling CMOS batteries:

Method 3: Special Jumper

This jumper (jumper) is also often found on various motherboards. To reset the settings in the BIOS using jumpers, use this step by step instructions:

It is also necessary to take into account the fact that the number of contacts on some motherboards may vary. For example, there are samples, where instead of 3-contacts only two or as many as 6, but this is an exception to the rules. In this case, you will also have to move the contacts using a special jumper, so that one or more contacts are left open. To find it easier to find fit, look for next with them the following signatures: "CLRTC" or "CCMOST".

Method 4: Button on the motherboard

On some modern motherboard there are a special button to reset the BIOS settings to the factory. Depending on the motherboard and the characteristics of the system unit, the desired button can be located both outside the systemic and inside it.

This button can be designation "CLR CMOS". It can also be indicated simply in red. On the system unit, this button will have to search from the rear to which various elements are connected (monitor, keyboard, etc.). After clicking on it, the settings will be reset.

Method 5: We use the BIOS itself

If you can enter the BIOS, then reset the settings can be done with it. This is convenient, as you do not need to open the system unit / laptop housing and make manipulation inside it. However, even in this case, it is desirable to be extremely careful, since there is a risk to aggravate the situation.

The settings reset procedure may differ slightly from the instructions described in the instructions, depending on the BIOS version and the computer configuration. Step-by-step instruction looks like this:

Reset BIOS settings to the factory state is not something complicated even for not too experienced PC users. However, if you decide on it, it is recommended to comply with certain caution, since the risk of harm to the computer still exists.

In general, if you need to reset the BIOS settings in the laptop from the name, there is little depends - almost in all lonely. It may be for example:

• ASUS (Asus), X550C, K50C, H81M K, K551L, X552CL.
• lenovo (Lenovo) 10160, V570C, C260, G580, G50, G570, B590.
• HP Pavilion, 620, G6 1210SR, 4510, COMPAQ NX6325, MSI Z77A G43.
• Samsung (Samsung) NP355V5C, NP350V5C, RC530.
• Acer Aspire (Acer) V5 471, V3 771G, V3 571G, 5742G, 8951.
• DNS (DNS) 0170703, Dell, Packard Bell, Sony Vaio, VGN NS31ER.
• Toshiba Satellite (Toshiba) A60, Prestigio 141A03 Shell, MSI H110M Pro VH.

The difference can be in the BIOS manufacturer if you want to reset to factory-default from the manufacturer.

Similarly, it is also absolutely independent of the Windows version: Windows 7, Windows 10, Windows 8 or XP is the prerogative of the BIOS itself.

Below will look at several options as you do, including on laptop models.

The first way to reset the BIOS settings in the laptop is to extract the battery.

On the motherboard, the laptop has a small battery that feeds the CMOS chip. When she discharged after several years, the laptop does not remember the date, forgets the settings and in some cases refuses to work at all.

If you pull it out, you can instantly reset the bios, just remove the power cord and pull the battery.

Then unscrew the housing cover, after which the match or toothpick gently move the small mounting bracket, and the battery will drop out of the socket.

This is usually a 3-voltolometric lithium battery with a CR2032 label (costs about five dollars).

ATTENTION: In the CMOS laptops, the battery is sometimes soldered. In this case, it is better not to touch it, but take advantage of the following way.

If your laptop is modern, then unscrewing is possible and nothing will have to. Turn the laptop the bottom of the bottom and see if the inscription is "CMOS".

If there is, then there should be a hole. Slisse into it a paper clip or something like that and hold about ten sec.

The second way to reset BIOS in a laptop - jumper

The second way is to reset the jumper, which is close to the aforementioned battery.

The jumper is described as "Clear CMOS", "CLR CMOS" or "Reset BIOS" depending on the motherboard installed on the computer. The appearance of the jumper also depends on the laptop model.

By default, it closes two contacts - the first and second. To reset BIOS you need to close the second and third contacts, wait a few seconds and move everything back to its original position.

If you do not have a jumper, you can use a conventional screwdriver while holding it in this position from several to tens of seconds (the longer, the better).

The third way to reset the BIOS in the laptop to the factory settings by entering it

In this way you need to enter the BIOS and in the settings to find the Load Bios Default string. So you can restore default values \u200b\u200bor factory settings.

You will have to confirm your choice with the "Enter" key, and sometimes the settings with the "F10" button.

To enter the BIOS, you need to immediately press the "Del", "ESC" or "F2" key, although other options are possible.

Note that in new versions of laptops there may be not a text screen, but graphic. But in general, the scheme is common.

Select it and click "Enter", and then confirm your solution - click "Yes". In principle, and how to go to BIOS, and how to reset it - all this is in the documentation for the laptop.

As already mentioned above, the BIOS reset on the laptop must still be confirmed by saving - that is, to select the menu item - "Save & Exit", save everything, and then perform overload.

Reset ASUS laptop to factory default settings

To do this, immediately after starting the PC launch, press the F2 key to get into the BIOS settings.

In some ASUS, to return to the factory default settings, turn it on and press the F9 key, you must see the download screen.

The recovery program will prepare the necessary files, and you will be prompted to restore the factory settings. All your data will be deleted.

Then the recovery process will be made automatically, without user intervention. During the recovery process, the laptop will restart several times.

Reset HP Laptop to Factory Settings Installed by default

To return to the factory default settings in HP, turn off the laptop and disconnect all connected to it.

Press the F11 key when you start the laptop and hold until it appears, HP Recovery Program is a recovery manager.

Select "Restore System". You will be asked to save the data you need, you can do it.

After the recovery process is completed, you get HP with a pre-installed Windows, all drivers and HP software will be installed.

Reset Acer Laptop on factory settings

To restore the Acer factory settings, turn it off, and then turn it on by holding down the Alt key and pressing the F10 key for about once in half a second.

The system will ask you to enter the password. The default password is 000000 (six zeros). Select from the proposed menu Reset to factory settings (Factory Reset).

In addition, the Acer laptop can return to the factory settings using the Acer Erecovery Management utility.

Reset SAMSUNG laptop factory settings

In Samsung, you can start the SAMSUNG Recovery Solution to restore the factory settings if you did not delete it.

Press the F4 key to start recovering Samsung settings to factory. Then follow these steps:

Restore checkpoint. Select "Full Recovery" (Restore Full)

Select the recovery point of the original computer status (factory). You will be prompted to restart the laptop - answer "Yes", then follow the instructions.

Reset to the factory settings for laptoptoshiba

To restore the factory settings in Toshiba, do this: press and hold the 0 (zero) key on the keyboard (digital keyboard on the right).

Turn on the laptop. Release the 0 button (zero) when it starts to sound. Then a program will appear that will allow you to restore the laptop to the factory settings. You just follow the instructions and indicate.

Fully in detail with all pictures, you can only describe for one specific model.

I wanted to describe the options for all models in this record. How did you solve you.

However, if something is not clear - write in the comments and I will give you a detailed answer. Successes.

This article on how to return the BIOS to the factory settings. There is a need for this if you yourself changed something. This could lead to such consequences: the unstable work of the computer (PC) / laptop, the inability to enable a PC / laptop, a black operating system boot screen, an unknown password to enter BIOS Setup and many others.

Zooming CMOS memory with hardware

Let me remind you that BIOS is built on CMOS technology (complementary logic on metal-oxide-semiconductor transistors).

Turn off the computer / laptop. Remove the power cord. Disconnect the battery (for a laptop). Further open the system unit / disassemble the laptop, because We need access to the motherboard. On the motherboard we find a battery CR2032.which looks like this:

Fig.1. CR2032 Battery, 3 Volta

Next to this battery we find a switch that signed Clear Cmos., CL_CMOS. , CRTC. , CCMOS. , Cl_rtc. etc. The name of the switches may be different. There can also be 2-PIN or 3-PIN to several times with a stuck in it. On laptops, the switch can be installed under the battery itself. That's how they should look like:

Fig.2. CR2032 and near 3-Pin jumper connector, which is signed on the motherboard as CLRTC

Fig.3. CR2032 and near 3-Pin jumper connector, which is signed on the motherboard as CCMOS

Anotherly different jumper is called this jumper. Jumper (eng. jump) - a jumper that allows you to set the device mode of the device with a closure (opening) of several contacts. In our case, the jumper can be connected to the place to 2 or 3-contacts (they are also called pIN.(from English pin)). To reset the CMOS memory (return the BIOS to the factory settings), you need to close these contacts with jumper for a couple of seconds, i.e. Put on 2 contacts (at a 2-pin configuration) or rearranged to position 2-3 from the position 1-2 (at a 3-pin configuration).

General way. Using switches, jumpers (jumpers) or buttons. To reset the BIOS settings or cleaning CMOS memory:
1. Switch a switch for a few seconds, or remove, set, switch to another position of the jumper.
2. Press the power block's power button. The computer will work but the screen can remain black.
3. Turn off the computer. Return the jumper into place or switch the switch to the original state.
4. Turn on the computer.
5. Enter B. BIOS Setup. And check all the installations.

Fig.5. BIOS Reset Button with CLR CMOS title

If the Clear CMOS switch on the motherboard is missing, or you did not find it, you need to do the following:
1. Remove the CMOS memory battery from the motherboard.
2. Close the contacts in the battery socket, for example, scolding to remove residual voltage in the CMOS memory circuit.
4. Return the battery to the place.
5. Turn on the computer.
6. Enter the BIOS Setup and check all the installations.

Intel motherboards remark. The methods described above are suitable for most system boards, an exception is models manufactured by Intel. If you are the manufacturer of this company's products, find the so-called password for passwords BIOS CONFIGURATION JUMPER. (BIOS configuration jumper) and stop it from position 1-2 to 2-3 position. Close the lid and feed the power unit and the monitor, then turn on the computer - it will automatically load the utility BIOS Setup. in configuration mode. The main difference is the optional Maintenance item (Fig. 3) containing, in particular, the option to remove all passwords CLEAR ALL PASSWORDS. Choosing it, you reset the forgotten passwords. After that, it is necessary to save the changes made (for example, by pressing and confirming your intentions), turn off the computer power, de-energize it and all the peripherals, open the system unit housing and return the BIOS configuration jumper to the initial position 1-2. To reset all BIOS settings, remove for 10-15 minutes of the battery.

This can be done using the Windows debugger. The procedure for such:

Start -\u003e All Programs ---\u003e Standard ---\u003e Command Line (for Windows Vista and Windows 7 Right-click on delay Command line And choose Run on the name of the administrator). When the window opens, enter debug. and press ENTER. Further commands depend on the BIOS manufacturer. After entering each line you need to press ENTER.

When working with laptops, it is problematic to disconnect the CMOS-memory battery, or use the jumper, since there is no other in explicit form may not be. The battery can be constructively completed with the CMOS-memory microcircuit. Yes, and disassemble the laptop is neither possible. In such cases, you can use the Master Passwords for service tags (codes shown in the three-five-time incorrect password input) or the laptop serial number. They will be discussed in other articles.

That's all! Thank you for your attention to new meetings on site pages.

Sometimes the novice user does not understand how serious the consequences of incorrectly made changes to the operation of the basic I / O system can be. However, not all users who can enter the "holy-saints" of the computer system, it is known how to reset the BIOS settings. But sometimes it happens that the user is extremely necessary to return the computing technology lost for one reason or another "stability parameters". Therefore, let's consider all the well-known and most applied methods for resetting BIOS settings to its original state.

The novice user is extremely important to know how to reset the BIOS settings!

And indeed it is! Unforeseen situations when it may be necessary to carry out such a program and technical procedure, as they say, WHO and a small trolley. The most common problem is the impossibility of loading OS - is often the result of incorrectly made changes to the operation of the BIOS firmware. There are often cases when the reason that caused the temporary inoperability of the computer becomes a banal power supply in the centralized network. We will not miss such an unfavorable moment as static stress. In general, you know how to reset the BIOS settings is important and necessary!

A few words about the autonomous "dependence"

Perhaps it will be a kind of discovery for you, but the motherboard is equipped with a special battery, the energy of which helps to store data on the launch of the computing machine in the current state. By specifying said, you can add: the changes made to the BIOS are written to a special memory microchip - CMOS.

If the above-mentioned element of the power fails (energy dried), it is likely that the computer system will begin to confine. By the way, it often helps to cure glitches a very simple action: pull the battery from the system board socket and turn it out again in ten seconds.

What you need to do to reset the BIOS to the factory settings

First of all, you can try to solve the above problem using the built-in firmware itself. That is, you need to enter the BIOS system and activate the recovery process manually. It is worth noting that, depending on the modification of the e-machine, its characteristics and the technologies embedded into it, which is installed on the device, the basic firmware may differ from itself such a systematic software.

Therefore, the BIOS login script on computers from different manufacturers is regulated by pressing a strictly corresponding button. Mainly use the duty key "Delete" or "F2". In any case, when the computer starts, a test information is displayed on the PC screen on what kind of key is responsible for the entrance to the BIOS.

Practical example

So, let's proceed to the immediate point of resolution of the issue: "How to reset the BIOS settings":

• After you find yourself in the work area of \u200b\u200bthe firmware, try pressing the "F9" key. In most cases, the use of this button activates automatic reset to the default settings.

• If the hot key does not work, then you should carefully inspect the BIOS interface for the presence of an inscription in the form of "Load Defaults ..." or something like that. Sometimes this option is hidden in one of the sections of the firmware.

In some cases, reset the default bios settings by reinstalling special CMOS jumpers.

How to do it?

Before proceeding to implement this event, turn off the computer and de-energize it. If you have technical documentation, it should be carefully learned.

• Unscrew the protective cover of the system unit.
• Find a "cherished" battery on the motherboard.
• As a rule, CMOS jumpers are in close proximity to the battery.

• Move the plastic "closer" for 1-15 seconds from position 1-2 to position 2-3.
• Set the auxiliary item to the previous place and close the body cover.

Portable Electronics Solutions

The above options can also be successfully implemented in a laptop if you need to reset the bios settings on the laptop. Nevertheless, with such "portable circumstances" some inconsistencies may arise. In particular, access to the CMOS battery in most laptops is simply closed.

Simply put, the battery is in the most "subsoil" of a compact device, and therefore without dismantling the cabinet parts (to get to the battery) to replace the battery will be unrealistic. Therefore, let's resort to another embodiment, which, by the way, is also effective and in relation to stationary computers.

Run a restoring utility

Through the start menu (in the search bar) or the checkbox of the "Run" service window (press the "Win + R" key combination) Enter the command: debug.

• For AMI BIOS: O 70 FF, then "input" and write: O 71 FF, press "ENTER" again and end all the symbol Q.
• With Award BIOS: O 70 17, O 73 17 and again Q.

You may come in handy this recommendation. However, there is one more option for resetting firmware settings in laptops: to close two special contacts on the motherboard for 10-15 seconds. However, this information is not always indicated in the technical passport of a particular computing device. For example, in some modifications of laptops, two such points are located in the immediate vicinity of RAM of Device Planks. In general, who is looking for - he will always find!

Summing up

Well, you can congratulate you, now you know how to reset the BIOS through the settings. Nevertheless, be selective when choosing one or another option to restore the factory parameters of the device. Because the Internet is a very tricky joke, and the advisers-sticks are even eliminating. Successful discharges and stability to your computational device!
