Sometimes a novice user does not understand how serious the consequences may be from improperly made changes to the operation of the basic input / output system. However, not all users who are able to enter the "holy-saints" of a computer system know how to reset BIOS settings. And in fact sometimes it happens that it is extremely necessary for the user to return to the computer technology the "stability parameters" lost for one reason or another. So let's look at all the known and most widely used methods for resetting BIOS settings to their original state.
It is extremely important for a novice user to know how to reset BIOS settings!
And indeed it is! Unforeseen situations, when it may be necessary to carry out such a software and technical procedure, as they say, a cart and a small cart. The most common problem - the inability to boot the OS - is often the result of improperly made changes to the BIOS firmware. It is not uncommon for cases when the cause of the temporary inoperability of a computer becomes a banal power supply drop in a centralized network. We will not miss an unfavorable moment like static tension. In general, knowing how to reset BIOS settings is important and necessary!
A few words about autonomous "dependence"
Perhaps for you it will be a kind of discovery, but the motherboard is equipped with a special battery, the energy of which helps to store data about the launch of the computer in an up-to-date state. Specifying the above, you can add: the changes made in the BIOS are written to a special microchip memory - CMOS.
If the above-mentioned battery fails (energy is exhausted), then it is likely that the computer system will start to fight. By the way, often helps to cure glitches very simple action: to pull out the battery from the socket of the motherboard and again to put it in place 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 with the built-in tools of the firmware itself. That is, you need to bake into the BIOS and activate the recovery process manually. It should be noted that depending on the modification of the electronic machine, its characteristics and technologies introduced into it, the basic firmware installed on the device may differ from itself similar system software.
Therefore, the BIOS login script on computers from different manufacturers is regulated by pressing a strictly corresponding button. The main key is "Delete" or "F2". In any case, when you start the computer on the PC screen, test information is displayed about which key is responsible for entering the BIOS.
So, let's proceed to the immediate solution of the question: "How to reset BIOS settings":
- After you are in the working area of the firmware, try pressing the "F9" key. In most cases, activating this button activates the automatic reset of the settings to the default settings.
- If the "hotkey" does not work, you should carefully examine 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, you can reset BIOS settings by default by resetting special CMOS jumpers.
How to do it?
Before proceeding with this activity, shut down the computer and disconnect it. If you have technical documentation, then it should be carefully studied.
- Unscrew the protective cover of the system unit.
- Find the "treasured" battery on the motherboard.
- Typically, CMOS jumpers are in the immediate vicinity of the battery.
- Change the plastic "contactor" for 1-15 seconds from position 1-2 to position 2-3.
- Install the replacement part to its original position and close the housing cover.
Solutions for Portable Electronics
The above options can also be successfully implemented in a laptop if you need to reset 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 located in the "bowels" of a compact device, and therefore without dismantling the body parts (to get to the battery), replacing the battery will be unrealistically difficult. So let's resort to another option, which, by the way, is also effective with respect to stationary computers.
Run the repair utility
Via the start menu (in the search box) or the checkbox of the service window "Run" (press the key combination "Win + R") enter the command: debug.
Next, in the console that opens, write the following:
- For AMI BIOS: O 70 FF, then "Enter" and write: O 71 FF, press "Enter" again and end with the Q symbol.
- WITH AWARD BIOS: O 70 17, O 73 17 and again Q.
Perhaps you will find this recommendation useful. However, there is another option for resetting the firmware settings in the laptops: for 10-15 seconds, close the two special contacts on the motherboard. However, not always such information is indicated in the technical passport of a particular computing device. For example, in some versions of laptops, two such points are located in the immediate vicinity of the RAM slats device. In general, who is looking for - that will always find!
Well, you can be congratulated, now you know how to reset BIOS through the settings. Nevertheless, be selective when choosing a particular option to restore the factory settings of the device. Because the Internet - a very tricky joke, and even the advisers-prikolistov more than enough. Successful dumps and stability to your computing device!
