The most important basic entry and output procedures are preserved in the BIOS, the self.Test procedure after loading and the system of self.Starting the system. The BIOS password is installed on the motherboard to protect encrypted authentication information related to BIOS.

Windows users who installed the BIOS password should authentify the password when entering the BIOS settings or when entering the computer operating system. The main functions of the BIOS password:

  • Prevent BIOS settings from other persons to ensure the normal operation of the computer.
  • Prohibit others use a computer to protect computer resources.

In BIOS, you can install two types of passwords: one. The user password, and the other. The administrator password. These two passwords are installed in different ways and can block the BIOS system settings and the operating system, respectively.

  • Errors in the choice of settings or dispersal of equipment, which is why the blue screen of “death” appears.
  • It is not possible to enter Windows due to lack of password.
  • It is optimized by components on the old BIOS, which does not withstand Armenia.
  • Lenovo laptop cannot load the OS.
  • PC cannot start Windows due to errors in choosing a boot priority.
  • Windows does not see a hard drive.

In most of the situations considered, the best way is to reset BIOS on the Lenovo laptop and thereby return it to factory parameters. But there are other malfunctions associated with “iron”. In this case, zeroing does not always give a result. In the Комментарии и мнения владельцев, tell us which method you use, and whether you managed to drop the BIOS yourself.

Number BIOS password on PC

To reset the BIOS password on a stationary computer is not a problem. It is reset to clean the CMOS flash memory-a small 32-foot PLCC chip on the motherboard, which stores BIOS settings.

Cleaning is performed in many ways, but since the entrance to the BIOS Setup is closed to us, and the operating system is not loaded, consider only hardware.

Attention! Before performing the following instructions, turn off the computer from the mains.

  • Temporary removal of the Flash Mapia power supply element. The CMOS memory is filled with CR2032 tablets (in the photo below at number 1), which is also placed on the motherboard. Remove it from the nest and set in 15-30 minutes in place.
  • Closing CLEAR CMOS contacts with a special jumper. Jampper (in the photo below at number 2). These contacts are usually located near the battery and, in addition to “Clear CMOS”, can be marked as “CLRTC”, “Clear RTC”, “CLR CMOS”, “CRTC”, “CCMOS” and T. P. In working condition, Jamper stands in position 1-2. To clean the flash memory, rearrange it on contacts 2-3, wait 30 seconds and return to place.

Removing a password from the BIOS laptop Emachines E510

In general, they brought a laptop with a request to see what can be done and brought to working condition. Previously, he visited the service where he was a verdict about the need to replace the packaging hard disk. Apparently there, to the heap, they also installed the password on BIOS (so that there is no temptation to contact somewhere else?). I can’t say, but the owner does not have a presentation about the password for turning on the laptop, but the password for the hard drive is asked after.

Well, for starters, let’s try to remove the password from the BIOS laptop. Having climbed over the network, I realized that the last practical tips ended in a year in 2005. Now no one wants to share secrets for free. True, specialized forums (at which you need to register) are found, where different codes are laid out for unlocking at the request of the participants, however, sources are kept in the strictest secret and are fanned by the range of mystery (probably in order to emphasize their chosenness before the rest).

At the end of the article I will give a reference to one such mysterious source that helped to unlock the Toshiba hard drive without communication with these “guru”. And the English.Speaking Google brought me there.

It was not difficult to remove the password from BIOS on Emachines E510, it was only necessary to drive the contacts of the battery. Honestly, I did not especially hope for success, but sometimes simple methods are very effective. I do not claim that this method of unlocking is suitable for all laptops, but it is worth a try, especially since it does not require any special knowledge and skills.

Emachines E510 laptop is practically the dream of a serviceman (if you do not need serious repair), t.To. Provides easy access to the insides. For example, you can clean it with only one back cover, though the latches are very tight. Having removed the lid, we get access to the desired battery:

Attention! Before closing the contacts, you need to turn off the power and remove the battery from the laptop. Just in case, he held a screwdriver (it was shelled) for a couple of minutes, because he certainly did not know and I don’t know how much was needed. The main result. Password on BIOS! However, happiness was not long.


Enter any set of characters and press Enter. There will appear a sign of incorrect password.

We recruit 2 more random numbers and BIOS will offer to enter a password for unlocking or continue loading the system.

We choose to enter the password unlock (Enter Unlock Password).

There will be a password that needs to be entered into my generator master of passwords BIOS.

In the service we enter this code and click get a password.

Depending on your laptop company, we enter the resulting code into the proposed field.

Now let’s go to the Security tab and remove the password. We press Enter against the SET SUPERVISOR Password field and enter the password that we generated in the service, and in the second and third field we write nothing just click Enter.

And now we do the same in the SET HDD Password field, remove the password for loading a hard drive.

Thank you very much for the article! The child pressed something on a laptop and an error occurred.I looked and decided to restart the laptop, and BIOS demanded some kind of password, and I still did not understand what happened there.

How to act if the password is lost

The situation is complicated if the user has forgotten the combination.

ON A NOTE. To achieve the result, you will have to experience all the proposed methods. Which of them works depends on the specific model.

With the help of a password master

There is a special portal generating the discharge code. It will help independently because Windows is launched or not. If the launch of the OS is blocked, you will have to go to the resource from a different device.

Let’s move on to action. Enter any characters several times in the entrance line in the BIOS. The text “System Disabled” will appear on the screen, which means blocking the system. There are several numbers at the end of the message.

We write down these values. They will be required to generate a new password.

BY THE WAY. There may be another option: BIOS will offer the Enter Unlock Password or continue to download the system. Choose the first action. The desired password will appear on the screen.

Let’s go to the BIOS Master Password Generator resource. Enter the previously recorded number, click the Get Password button.

We view the data provided by the site. We will use only those results that are closest to the PC model number.

ATTENTION. We collect the resulting combination carefully: the code is sensitive to the register.

Manipulations with an element of nutrition

The motherboard is supplied with a battery. In many devices, all BIOS settings are stored on this element.

IMPORTANT. Before disassembling the device, be sure to de.Energize it: pull out the adapter from the outlet, extract the battery.

Remove the back cover of the laptop, find a fee and a battery on it.

  • We extract the element and leave for about 24 hours, during this time the memory on it will be erased;
  • A faster and practical technique-we will close the contacts of the battery, within 1-2 hours it can be put in place.

Note that the most difficult point is the extraction of the part. The motherboard is often located deep in the case, which will require caution.

RECOMMENDATION. If the component is in an inaccessible place, there is a risk of damaging other components. In this case, we advise you to contact the service workshop.

Emergency button CMOS

This key, like the battery, is built into the motherboard. It is specially designed to erase BIOS information. Its exact location is indicated in the instructions for the board or on the manufacturer’s website.

The part is performed in the form of a button or connectors. The complexity of work is associated with its whereabouts, as in the case of the nutritional element.

Just click on the button. The password is immediately dropped.

Special programs

Applications come in handy if, when a password is lost, it is possible to run Windows.

CMOS De-ANIMATOR utility, the new version works with 86- and 64-bit platforms. Supports only English. Leads control amounts of CMOS memory to invalid values. Thanks to this, all settings (including passwords) are reset.

Right.Click on the program icon. Choosing “Launch on behalf of the administrator”.

Click the “Continue” button, restart PC. An erroneous control amount will appear at the entrance. Now BIOS becomes available without entering a password.

ON A NOTE. Some antiviruses perceive the utility as malicious.

In case of distrust of such software, there is another method. Let’s go to the Dogbert blog. This contains information about various brands of laptops.

An article with the table will open, it will have active links to suitable applications.

Disadvantages: only part of the manufacturers of electronics is presented here. The last publication dates back to 2016. There are texts only in English.

We load and install the tool. In his working window we enter the previously recorded digital number, click Enter. After a while, a universal password will be created. We use it to reset BIOS.

Other methods

There is an alternative-these are MC-DOS requests. They make incorrect control amounts of memory. Used in two versions:

Lenovo G510 “System Password” RT809F

  • Special software is recorded on a removable carrier (or disk), then act using a command line;
  • The command line starts on behalf of the administrator directly to Windows (through the search line of the Start button).

In the window we consistently enter the commands (we will not forget that “o” is a letter):

Reload the device. We will make sure that the settings were set by default.

ATTENTION. The technique is used only in extreme cases and is suitable only for experienced PC owners. Otherwise there is a chance to harm a laptop.

The loss of code from entering BIOS complicates the user’s tasks. After all, password reset methods have different efficiency, depending on the specific model. Let’s try to solve the issue on our own. If for some reason the listed methods do not work, contacting the service center will help.

And yes. You can not fall out. Crushes quite well. The main laptop before the firmware is completely provided, do not forget
