How to remove the password on the bios at the laptop

Password on BIOS users put in order to protect their computer from the penetration of unauthorized persons. To put a password is not difficult, and it will provide reliable protection, but if the password is randomly forgotten and it is safely forgotten, then difficulties may arise with recovery. Unlike desktop PCs, passwords in laptops are stored in non-volatile memory. To get a positive result, act according to the instructions.

Password reset methods (zero) BIOS can be several. It all depends on the manufacturer of a laptop. On many budget and serial models (Toshiba, Asus, Acer, HP, Samsung, etc.), the password reset on the BIOS is a fairly simple operation. First of all, you need to explore the documentation for the laptop. Consider whether there is a jumper on its motherboard (jumper). Jumper contacts are usually indicated by the CMOS inscription, which is located next to the battery.

Disconnect the laptop completely, find the jumper on the board, close the second pair of contacts on the pitch. After 10-15 seconds, return the jumper into place. Instead of jumpers on some models there may be simply a pair of contacts. Close them for a few seconds by any metal object. After that, the BIOS settings will be reset to factory.

Turn on the laptop. It will not be loaded, but the CMOS settings are reset. The screen may appear on the need to press the "F1" key, it should be done to set the BIOS parameters. After that, select "Save and Exit". Now booting OS will continue without a password request for BIOS.

In the event that the jumper is not found or it is not provided for by the system board manufacturer, you can use another method. Patty a sharp CMOS feed battery and remove it for a while. Sometimes 5-10 minutes is enough to zeroing the BIOS, but it is better to increase the time to several hours. You need to execute this operation when you have a laptop full, it is better to remove the battery.

On expensive models of laptops, the information protection technique may be more complex and reliable. On such motherboards, hack the password on the BIOS or the OS load is almost impossible. But you can try, applying a software disk for BIOS. Enter the operating system as an "administrator". Find the command line in the Standard folder and enter the command "debug.exe" and press "ENTER". Enter the following commands sequentially by pressing "Enter" at the end of each: "O702E", "O71FF", "Q". After restarting the laptop, the CMOS error message will be released on the screen and will be prompted to reconfigure the BIOS. This means that the BIOS settings are reset and you can optionally restore parameters or leave them unchanged.

Since all methods for resetting the password on the BIOS (zero) may not give the desired result, then before passing the laptop through the BIOS, it is necessary to weigh everything well. Relief jumpers may not be, and the removal of the battery does not always help. If the password is still installed and none of the described methods approached your laptop model, the password failed to reset, it remains only to contact the service center.
