Sometimes a novice user does not understand how serious the consequences of improper changes to the operation of the basic input / output system can be. However, not all users who can enter the "holy of holies" of the computer system know how to reset BIOS settings. But sometimes it happens that it is imperative for the user to return the "stability parameters" lost for one reason or another to computer technology. Therefore, let's look at all the known and most used methods of resetting BIOS settings to their initial 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 program-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 improper changes to the BIOS firmware. There are frequent cases when the cause that caused the computer to become temporarily unavailable is the banal difference in the supply of electricity to a centralized network. We will not miss such an unfavorable moment as static voltage. In general, knowing how to reset BIOS settings is important and necessary!
A few words about autonomous “addiction”
Perhaps this 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 computer in an up-to-date state. Concretizing the above, we can add: changes made to the BIOS are recorded on a special memory microchip - CMOS.
If the aforementioned battery fails (energy has run out), then it is likely that the computer system will start to strike. By the way, a very simple action often helps to cure glitches: remove the battery from the socket on the system board and put it back in place after ten seconds.
What you need to do to reset BIOS to factory settings
First of all, you can try to solve the above problem using the built-in firmware of the 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 electronic machine, its characteristics and the technologies embedded in it, the basic firmware installed on the device may differ from similar system software.
Therefore, the scenario of entering the BIOS on computers from various manufacturers is regulated by pressing a strictly corresponding button. Mostly the standby key “Delete” or “F2” is used. In any case, when the computer starts up, test information is displayed on the PC screen about which key is responsible for entering the BIOS.
Practical example
So, we will proceed to the immediate moment of resolving the question: "How to reset BIOS settings":
- Once you are in the working area of ​​the firmware, try pressing the F9 key. In most cases, activating this button activates an automatic reset to the default settings.
- If the hotkey does not work, then you should carefully examine the BIOS-interface for the presence of the inscription in the form of "Load defaults ..." or something similar. Sometimes this option is hidden in one of the sections of the firmware.
In some cases, resetting BIOS settings to default can be done by reinstalling special CMOS jumpers.
How to do it?
Before you begin this exercise, turn off the computer and turn off the power. If you have technical documentation, then it should be carefully studied.
- Unscrew the protective cover of the system unit.
- Find the "cherished" battery on the motherboard.
- Typically, CMOS jumpers are in close proximity to a battery.
- Rearrange the plastic “contactor” for 1-15 seconds from position 1-2 to position 2-3.
- Reinstall the accessory part and close the housing cover.
Portable Electronics Solutions
The above options can also be successfully implemented in a laptop if you need to reset BIOS settings on a laptop. However, in 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 very depths of the compact device, and therefore, without dismantling the case parts (to get to the battery), replacing the battery will be unrealistically difficult. Therefore, let's resort to another option, which, incidentally, is also effective in relation to stationary computers.
Run the recovery utility
Through the start menu (in the search bar) or the checkbox of the “Run” service window (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 Q.
- WITH AWARD BIOS: O 70 17, O 73 17 and again Q.
You might find this recommendation useful. However, there is another option for resetting the firmware in laptops: for 10-15 seconds, close two special contacts on the system board. However, such information is not always indicated in the technical passport of a particular computing device. For example, in some versions of laptops, two of these points are located in the immediate vicinity of the RAM strips of the device. In general, he who seeks will always find!
To summarize
Well, you can be congratulated, now you know how to reset BIOS through settings. Nevertheless, be selective when choosing one or another option to restore the factory settings of the device. Because the Internet is a very tricky joke, and there are more than enough prankster advisers. Successful dumps and stability to your computing device!
