The BIOS needs to be reset often on laptops, when the user meets face to face with a series of problems that can only be remedied by resetting the BIOS.
Some problems can be eliminated only by a complete reset of the settings; But the user needs to know about what this entails and how to do it.
The most common problem is not in the hardware part, it will help restore the device to life.
Given that many business computers remain in the "manufacturer" state, the default settings are often appropriate for a successful start-up of the computer. After you reset the settings and restart the computer, think about how to take a technician look at the computer for larger problems.
Reset the Asus laptop to the factory default settings
The exact key depends on your computer. If you have another brand of computer, carefully look at the screen when you first turn it on - it usually tells you. To find the exact procedure for your computer, refer to the user manual. Turn off the computer and disconnect it from the wall.
1. Details of the reset
It would seem that resetting the settings to the factory settings does not represent anything complicated, or it can not be complicated. But the user who faces this for the first time will need to specify the "path" and answer the questions.Why do I need to reset the BIOS on the laptop:
- the need to reset the parasitic BIOS due to lost access to it. But you need this only in the case when you will address often to the BIOS settings;
Using the Debug utility
Open the housing cover, usually by removing one or more screws and sliding the cover back to the front of the machine and removing it. The battery will be a small cell in the form of a coin, and it can be snapped or cut into the socket. If you can not get it without forcing it, do not remove it. Some computers have removable batteries, others - no.
Reset BIOS settings to ASRock UEFI BIOS
Replace the battery after waiting for at least five minutes to get the extra chip chip time of the metal oxide semiconductor chip to lose the memorized settings. Replace the battery, close the case, connect the computer and turn it on. The settings will be reset to the factory default settings. If they do not match, repeat the process, leaving the battery longer before replacing it.
- incorrect "overclocking" of the processor, with the highest, critical values of the bus frequency, or memory timing. In general, most often, it is not recommended to overclock the processor on laptops;
- The system can not boot, but the BIOS is available;
- the BIOS was modified differently by an experienced user, which led to a malfunctioning system.
2. How can I reset BIOS. Variants.
For PCs and Laptops there are several basic options for resetting the BIOS to factory settings:- using the interface of the BIOS, if it is available;
- with the help of additional software, is most often applicable for 32-bit OS;
- mechanically.
Other ways to reset to the factory settings of the PC can be found in its documentation, if it exists. Find instructions for certain device models can also be found on the Internet, or on the manufacturer's website.
3. Factory-set via BIOS
Reset BIOS settings can occur through the BIOS itself, using a special utility already built into it beforehand. Specifically, you need to go to the interface. The transition to the BIOS interface can be done via the buttons: Delete, F2, 10, 11, Esc. Most often this button is listed at system startup. The picture shows an example.
His work has appeared in trade publications, such as the "Real Estate Magazine in Minnesota" and "Attorney of the Association of Multi-family Housing in Minnesota." Lander holds a Bachelor of Arts degree in Political Science from Columbia University. It can be a key combination or be in the "Advanced" settings menu. At the bottom of the screen, a shortcut to the keyboard is displayed, if applicable. The option "Restore default values" can also contain the word "default" or "settings", among others: "factory", "optimized", "fail-safe", "system" or "configuration".
After you are in the BIOS menu, you need to find a special "Exit" menu and select the "Load setup Defaults" item. Confirm the reset with the "yes" button, so the factory settings will be used. After confirming the action with the F10 key, all changes will be saved.
Some models of laptops have a different name for the BIOS reset point. For example, Sony - it's "optimized defaults", that is, using this item you can reset BIOS settings.
In Toshiba, Samsung and HP, this item is under the F9 key and it is called "Setup Defaults".
For older models, these items are most likely: Use Default Settings or Set BIOS Default.
Turn off the computer and unplug the power cord. Remove the battery if you have a laptop. Position the computer so that you can remove the sidebar for desktops or the bottom panel for laptops. Disconnect all attached devices, and then move the system to a flat, stable and tissue-free location if the current location does not provide easy access.
Methods for resetting BIOS settings to factory settings
Touch the nearest metal object, like a door handle or kitchen utensils, to defuse static buildup. Remove all screws and quick bolts holding the side panel of the computer. For laptops, remove the screws holding the removable bottom panels.
Most often, resetting the settings will turn on the PC and its normal boot.
But in the event that an error occurred during zeroing of the BIOS, for example, on the system media selection point, you will need to go back to the BIOS and go to the special settings:
1. Go to BIOS;
2. Find the Boot partition;
3. In the Boot Mode tab, change the UEFI item to Legacy;
4. Save the settings and reboot the system.
This method has a chance to fail, for example, if a password is set on the BIOS, or it is unavailable for some other reason.
Slide the sidebar for desktops or remove the bottom panels for laptops. It is a silver round plate about the size of a two-fold quarter of a coin. Leave the battery from the computer for five minutes, and then return the battery to the place on the motherboard.
Close the panel or panels and return all screws and quick bolts to their original position. Connect the power cable and any peripherals, which you disconnected from the computer. Insert the battery back into the laptop. Touch a metal object before working inside the computer to defuse static build-up, and avoid working in areas with fabric surfaces. When you find and choose, you will most likely be asked if you really want to load the default values. After the default values are set, make sure that you have saved and exited, and not just go out. Static discharges can damage or destroy computer parts. . If you recently added new hardware or reset the default values, this did not solve the download problems, you can also reset the configuration data.
4. Resetting the BIOS using the DEBUG program
You can change the BIOS interface and reset it using a special add-on for Windows OS. Most often it is built into the x32 system and its launch should occur "on behalf of the administrator".1. Open the program "execute" Win + R;
2. Type "debug.exe";
3. Now enter "o702E", "o71FF" and "q" alternately;
4. Confirm the entry with the "Enter" key.
In the Advanced section, the down arrow to the Reset Configuration Data option, change the Disabled or No to Enabled or Yes. Wait 5 minutes after removing the battery, then return the battery to the motherboard and turn it on. Information about their detection can be found in the documentation of your computer or motherboard.
Support sites for motherboards
Each motherboard is different. If you still have problems, it is important to consult the documentation for your particular motherboard. Below you can find links to the support sites of most major manufacturers of motherboards.
After this action, all BIOS settings will be reset. And after rebooting the system, the user will be notified that it is necessary to check the BIOS settings. Next, BIOS will need to be customized, or left as it is.
The disadvantage of this software is the inability to run x64 Widnows on the OS. And this means that most of the modern computers will need to be "nullified" using other methods.
5. Mechanical (hardware) method of BIOS reset
Such a "hard" reset bIOS settings The laptop is needed when the BIOS password is forgotten, unknown, or in any other case, when the BIOS is unavailable.In this case, the only way out is a hardware reset of the BIOS.
Resetting the BIOS with the button
In some cases, you may need to open a computer. If you do not see the key displayed on the screen, refer to the manual of your computer. On different computers different keys are used. The exact location of the jumper can be found in the motherboard manual. If you want to use a jumper on the motherboard, refer to the manual for more detailed instructions.
However, the basic process is quite similar to all computers. Turn the computer's power switch to turn off the power. Make sure that you are grounded so as not to damage the motherboard with static electricity before touching it. Set the jumper to the "clear" position, turn on the computer, turn it off again, set the jumper back to its original position - and you're done.
Laptops released 2-3 years ago have this button in a prominent place, so as not to resort to disassembly of the device. To reset the BIOS using the button, you need:
1. Disconnect the laptop completely, turn it upside down;
2. At the bottom, find the inscription "CMOS", there will be a special hole near it, through which you can reset the BIOS;
3. In the hole found, insert a suitable object such as a "clip" or "carnation" to hold the button for 30 seconds or more;
4. Turn on the laptop.
In the event that there are no holes, you need to disassemble it and find such a button.
Before removing the laptop, remove all power cords and other peripherals, including the battery.
If the battery does not discharge, do not press it. First, make sure that the computer is turned off and you are grounded so as not to damage the motherboard with static electricity. Locate on the motherboard a round, flat silver battery and gently remove it. Wait five minutes before recharging the battery.
Exit the menu. It seems that each manufacturer has its own way of formulating it. This should be fairly easy, however, if you can find this reset option. Start with the fact that your computer is disconnected from the network. If you are using a laptop or tablet, make sure that the main battery is also removed.
Removing the "battery" on the motherboard
This is the simplest way to "hard reset" the BIOS. Most of the laptops will reset the settings by extracting the battery highlighted in the picture below.
Removing the battery, you turn off the BIOS power and, accordingly, reset all settings and the password itself. The board should be de-energized from 5 to 40 minutes, it all depends on the model. Sometimes this may not work.
The battery is always in a prominent place and is located closer to the edge of the motherboard and nothing hinders its extraction.
The user must:
- remove the lid;
- completely de-energize the devices, remove the laptop battery;
- find the battery;
- remove it, carefully;
- wait up to 40 minutes for it to work;
- install a removable battery in place;
- turn on the notebook;
- BIOS settings for the new, set the date, hours and other parameters.
At present there are also non-removable batteries. For them, this method is impossible. Therefore, you can use the following method.
Jumper cleaning - switching
Close the panel or battery compartment, and then reconnect or reconnect the main battery of the computer. Never before did they open their desktop computer? Complete step-by-step guide. For example, change the setting that will cause the computer to stop working correctly and you will lose data.
- Click Start, click Computer, and then restart.
- Some models can use other buttons.
- The button is displayed during the download process.
This method of switching jumper is possible in the event that the laptop has a special jumper, which is responsible for resetting the BIOS settings.
In order to find it - you need to "climb" under the cover of the laptop and get access to the motherboard. Most often, this switch is located directly near the battery, and the jumper is signed by one of the following names: CLRTC, CLR and CCMOS.
Reset BIOS settings by pulling out the battery
- Remove the 2-pin jumper connector.
- Move the 2-pin jumper connector back to the password jumper.
- Connect power to the computer and other devices and turn on the power.
It is extremely important for a novice user to know how to reset BIOS settings!
This is usually done if you do not have access to jumpers or if it's a laptop. Note. This is true for both desktop and portable systems. However, for portable systems, a flap is required at the bottom or, possibly, a keyboard that can be removed to replace the battery of the button element. This is not possible with every laptop. Please see the support guides below to see if this method works with your system.
Most often the jumper site consists of three contacts. To reset the BIOS, you need to move this jumper one step, that is, from a certain position to the next, and vice versa.
After the jumper is switched, press the button for switching on for more than 10 seconds.
The laptop, of course, will not be included, but the signal will be transmitted to the jumper. After that, return the jumper to the position in which it was located and proceed to turning on the laptop and setting the reset BIOS.
The hardware reset method BIOS, almost 100% will ensure their reset, but in the event that the laptop is still under warranty - this action will lead to a loss of warranty on it, so it is best to use the hardware method after the warranty period expires.
6. The result
The provided BIOS reset procedures will help you to cope with these problems without specialists. Most often, no more than a couple of minutes should go to solve this problem.But if no method has helped - contact a service specializing in this direction. The device can be protected by means of some additional microcircuit.
Disconnect the system from an external power source and remove the main battery from the laptop. Figure 2: Battery button on the desktop. Figure 3: Button battery in a portable system. If this jumper is open and the system is running, system password is removed and disconnected. Closing the jumper will briefly activate the password.
The password jumper plug must be re-installed for password jumper settings to enable password properties again. Connect the keyboard and mouse, turn on the computer and monitor and turn on both devices. Shut down the computer after the operating system is booted. Remove the keyboard and mouse, and then disconnect the computer and monitor from the electrical outlet. Press the power button on the computer to ground the system board. Secure the 2-pin jumper plug back to the jumper of the password on the main board. Connect the computer and the equipment to the power source and turn it on.
- Remove the computer cover.
- Find the 2-pin password jumper on the system board.
- Remove the 2-pin jumper connector and set it aside.
- Replace the computer cover.
Many problems on the laptop can be solved by resetting BIOS settings to factory settings (sometimes, they are also called optimal or safe).
In general, this is quite easy, it will be more difficult if you put a password on Bios and when you turn on the laptop, it will ask this same password. Here, without dismantling the laptop can not do ...
If you need further assistance, contact the technical support. For those who do not know, this is the firmware stored on the chip on the computer's motherboard, which is basically a set of instructions that are launched to boot the operating system.
You will see the keys that will work on your hardware at boot time in the bottom left or right corner using the boot or install options. If you see this, you can also use this option. Use the arrow keys on the keyboard to go to the "Standard configuration settings" tab.
In this article, I wanted to consider both options.
1. Resetting Bios BIOS settings to factory settings
To enter Bios settings, you usually use the keys F2 or Delete (sometimes the F10 key). It depends on the model of your laptop.
Find out which button is easy to press: reload the laptop (or turn it on) and see the first welcome window (it always indicates the button for entering Bios settings). You can also use the documentation that came with the laptop when you bought it.
Go to the "Time and Date" settings on the screen. Use the and keys to set the current date and time. When you are asked to confirm the settings, press the "Enter" key. The computer will reboot and boot into the operating system. Follow the instructions below to clear the settings.
Incorrect settings can remove the entire system, so the download is not possible. Typically, the corresponding button is displayed during the download process. . There are even two different methods. This method is different from the motherboard motherboard, so you should read the instructions here.
And so, we will assume that you have entered Bios settings. Next we are interested in exit tab. By the way, in notebooks of different brands (ASUS, ACER, HP, SAMSUNG, LENOVO) the name of Bios sections is almost the same, so there is no sense in making screenshots for each model ...
Next, in the Exit section, select the line of the form " Load Setup Defaults"(Ie loading the default settings (or default settings)). Then in the pop-up window you will need to confirm that you want to reset the settings.
And it remains only to leave Bios with the saved settings: select Exit Saving Changes (first line, see screenshot below).
By the way, in 99% of cases with reset settings the laptop will load normally. But sometimes there is a small mistake and the laptop can not find where to boot it (ie from which device: flash drive, HDD, etc.).
To fix it, go back to Bios and go to the section Boot.
Here you need to change the tab Boot Mode: UEFI change to Legacy, then exit Bios with saving settings. After rebooting - the laptop should boot normally from the hard drive.
2. How do I reset Bios if it requires a password?
Now let's imagine a more serious situation: it happened that you put the password on Bios, and now it's forgotten (well, or your sister, brother, friend put a password and calls you to help ...).
Turn on the laptop (in the example of the laptop company ACER) and see the following.
For all attempts to bust - the laptop responds with an error and after a few incorrect passwords entered it simply turns off ...
In this case, you can not do without removing the back cover of the laptop.
There are only three things to do:
- disconnect the laptop from all devices and generally remove all the cords that are connected to it (headphones, power cord, mouse, etc.);
- remove the battery;
- remove the protective cover random access memory and hDD laptop (the design of all laptops is different, sometimes it may be necessary to remove completely the rear cover).
Under the slats of RAM there are two contacts (they are still signed by JCMOS) - they are what we need. Now do the following:
- close these contacts with a screwdriver (and do not open until you turn off the laptop.) Patience and accuracy are needed here;
- connect the power cord to the laptop;
- turn on the laptop and wait about a second. 20-30;
- turn off the laptop.
Now you can connect RAM, hard drive and battery.
We need to say a few words about the "pitfalls":
- not all laptops will have two contacts, in some of them there are three and for resetting it is necessary to rearrange the jumper from one position to another and wait a few minutes;
- instead of jumpers, there can be a zeroing button: just press it with a pencil or pen and wait a few seconds;
- you can also reset the bios if you take out the battery for a while from the laptop's motherboard (a battery in the form of a tablet, a small one).
This is all for today. Do not forget passwords!
