After the setting is completed, the user needs to enter the password and user name every time to start the BIOS Setup and the BIOS system. , When the user forgets the set password or user name, currently he can only disassemble the chassis, remove the BIOS chip and re-program it, and then reinstall it back. The motherboard needs to be reworked, so that the user cannot operate it by himself, and professional maintenance is required. Usually, the motherboard can only be replaced for the customer. In addition, if the BIOS chip is repeatedly disassembled and welded, the BIOS chip will be damaged and the service life of the BIOS chip will be affected.

In addition to re-burning the BIOS chip, the user name and password set in the BIOS Setup can also be cleared by using the hardware jump cap to clear the COMS (clear COMS) information. However, hardware such as the Loongson platform desktop does not have a reserved interface, and Hardware jump caps are not supported to clear COMS information. Therefore, the user name and password can only be cleared by re-burning the BIOS.

In order to avoid the complicated operation of removing the BIOS chip to clear the BIOS Setup password, reduce the damage of the BIOS chip, and improve the efficiency of the user in maintaining the BIOS system, the embodiment of the present invention provides a method for clearing the BIOS password, by obtaining the current real-time clock time of the system. , and determine whether the current real-time clock time is the system default time. If it is the system default time, the BIOS will clear the current user name and current password in the BIOS Setup. The system default time is the time obtained by reconnecting the power supply after the BIOS is discharged. , and the time can be obtained by the user removing the battery of the motherboard and then re-installing the battery, without removing the BIOS chip and re-burning to achieve the purpose of clearing the current user name and current password.

FIG. 1 is a flowchart of a method for clearing a BIOS password provided by an embodiment of the present invention. As shown in FIG. 1 , the method includes:

S10: Obtain the current real-time clock time.

In a specific embodiment, the current real-time clock time obtained in step S10 may be obtained each time the BIOS system is started, or obtained when the user starts the BIOS system and enters an incorrect user name and password, which is not limited in the present invention. Of course, in order to save resources, it is preferable to obtain the current real-time clock time when the user name and password input by the user are incorrect. In order to prevent the user from entering the wrong username or password, and it is not when the user forgets the username or password that triggers the acquisition of the current real-time clock time, the current real-time clock can be obtained after the user has entered the wrong username or password for a preset number of times. time.

S11: Determine whether the real-time clock time is the system default time, and if it is the system default time, clear the current user name and current password; wherein, the system default time is the time obtained by reconnecting the power supply after the BIOS is discharged.

After obtaining the current real-time clock in step S10, determine whether the current real-time clock is the default time of the system, if it is the default time of the system, then clear the current user name and the current password in the BIOS Setup, wherein, the default time of the system is to reset the time after the BIOS is discharged. The time obtained by connecting to the power supply, that is to say, the default time of the system can be obtained when the user removes the battery on the motherboard, discharges the BIOS, and then loads and installs it back. Current username and current password.

It is understandable that when the user removes the battery on the motherboard to discharge the BIOS and then installs it, the current real-time clock time obtained is an illegal time, that is, the time is not within the time range preset by the user. At this time, the system After it is determined that the acquired current real-time clock time is illegal time, the real-time clock time is rewritten to the default time of the system, so that the user obtains the default time of the system by removing and installing the battery.

In the specific implementation, when the user forgets the user name or password set by himself, the battery on the motherboard can be removed to discharge the BIOS, and the battery is installed after the BIOS discharge is completed. The current real-time clock time obtained at this time is If the time is illegal, the system will rewrite the real-time clock time to the system default time, that is, when the current real-time clock time is the system default time, it can be determined that the BIOS system needs to clear the current user name and current password. After the user removes and installs the battery to clear the current user name and current password of the BIOS Setup, the system may prompt the user to reset the user name and password.

It should be noted that the technical solutions provided by the present invention are not only applicable to hardware platforms without reserved interfaces such as Loongson platform desktops, but also to servers, PCs, notebooks, all-in-one computers and other devices under any platform.

The method for clearing a BIOS password provided by the embodiment of the present invention includes acquiring the current real-time clock time of the BIOS system, judging whether the acquired real-time clock time is the system default time, and if it is the system default time, clearing the current user name and current password of the BIOSSetup , where the default time of the system is the time obtained by reconnecting the power supply after the BIOS is discharged. It can be seen that, in the technical solution provided by the present invention, when the user forgets the set password, there is no need to remove the BIOS chip and re-program it. By obtaining the current real-time clock time of the BIOS system, it is judged whether the current real-time clock time is the system default. Time, if it is the system default time, the current user name and current password of the BIOS Setup can be cleared, and the BIOS chip does not need to be removed from the motherboard to obtain the system default time, the user only needs to remove the battery from the motherboard, discharge it, and then reinstall the battery It can be obtained, so that the user can reset a new user name and password, thereby avoiding the damage to the BIOS chip that may be caused by removing the BIOS chip and re-burning it and soldering it back, and improving the efficiency of the user to maintain the BIOS system.

In a specific embodiment, when the user removes the battery on the motherboard to discharge the BIOS, and then installs the battery back, the current real-time clock time obtained by the BIOS is not within the preset time range, that is, the current real-time clock is determined. The clock time is illegal. In this case, the system resets the real-time clock time to the system default time. After determining that the current real-time clock time is the system default time, the current user name and current password of the BIOS Setup are cleared. For ease of understanding, examples will be given below.

For example, the preset legal time range is from January 1, 2000 to December 31, 2099. Among them, January 1, 2000 is the default time of the system. When the user removes the battery and waits for the BIOS to fully discharge, the battery is installed until On the motherboard, if the current real-time clock time obtained by the system is not within the period from January 1, 2000 to December 31, 2099, it can be determined that the current real-time clock time is illegal, and the current real-time clock time is rewritten as 2000. January 1, that is, rewritten to the system default time. Thus, after the system determines that the current real-time clock time is the system default time, the current user name and password are cleared.

For the preset time interval, that is, the legal time, the user can set it according to their preferences, or the system can regularly update it according to the current time. For example, the preset legal time range is from January 1, 2000 to December 31, 2099, which can be updated to January 1, 2003 to December 31, 2102 after 3 years. Not limited.

In the method for clearing the BIOS password provided by the embodiment of the present invention, before judging whether the current real-time clock time is the system default time, it is first judged whether the current real-time clock time is an illegal time, and if it is an illegal time, the current real-time clock time is reset. Write it as the system default time, otherwise, start the BIOS system normally, thus, the user can achieve the purpose of obtaining the system default time by removing and installing the battery, that is, removing and installing the battery to achieve the purpose of clearing the current user name and current password of the BIOS system .

On the basis of the above embodiment, in order to avoid the waste of resources caused by obtaining the current real-time clock time when the user remembers the user name and password, before obtaining the current real-time clock time, first determine whether the current password and/or the current user name input by the user is wrong, If it is wrong, it is determined that the user has forgotten the current user name and current password, and the current real-time clock time is obtained immediately, and it is judged whether the current real-time clock time is the system default time. If it is the system default time, the current user name and password are cleared.

In the method for clearing the BIOS password provided by the embodiment of the present invention, before judging whether the current real-time clock time is the system default time, it first determines whether the current real-time clock time is an illegal time, that is, whether the currently acquired real-time clock time is a preset time If the time in the interval is illegal, the current real-time clock time will be rewritten to the system default time, so as to achieve the purpose of clearing the current user and password of the BIOS, and avoid removing the BIOS chip from the motherboard and re-burning it in the installed computer. Complex operation, improve the service life of BIOS.

On the basis of the above embodiment, considering that the user may enter the wrong username or password by mistake, if the current real-time clock time is obtained once the wrong input is made, it may cause a waste of resources and bring a bad experience to the user. , therefore, after judging that the current user name and the current password input by the user are incorrect, determine whether the number of current input errors reaches the preset number of times, and if it reaches the preset number of times, enter the step of acquiring the current real-time clock time, and then determine the acquired real-time clock time Whether the time is the system default time to determine whether the current user name and current password need to be cleared.

It is worth noting that when the user enters the wrong username and password, and the number of errors has not reached the preset number of times, the system prompts the user to re-enter the current user name and password. When the number of errors reaches the preset number of times, the system prompts the user to enter the number of times. The upper limit, please enter after a preset time, or prompt the user to enter the upper limit, please reset the password. The present invention does not limit the content of the reminder.

In the method for clearing the BIOS password provided by the embodiment of the present invention, when the number of incorrect user names and/or passwords entered by the user reaches a preset number of times, the step of obtaining the current real-time clock time is entered, so as to determine whether the current real-time clock time is the system default time, so as to determine whether the current user name and current password need to be cleared. If the entered user name and password do not reach the preset number of times, there is no need to obtain the current real-time clock time, and the BIOS system can be started normally. Unnecessary operations caused by the current real-time clock time lead to waste of data, thereby improving the maintenance efficiency of the BIOS system.

In a specific embodiment, after the user removes the battery on the motherboard to fully discharge the BIOS, and then installs the battery back to the motherboard, the current real-time clock time obtained at this time is an illegal time, that is, the current real-time clock time is not preset. If the current real-time clock time is within the time interval, the current real-time clock time will be rewritten as the system default time. When the current real-time clock time is determined to be the system default time, the current user name and current password of the BIOS Setup will be cleared. After clearing the current user name and password, the system can prompt the user to reset a new password and user name.

In the method for clearing the BIOS password provided by the embodiment of the present invention, when the user forgets the set password, there is no need to remove the BIOS chip and re-program it. By obtaining the current real-time clock time of the BIOS system, it is judged whether the current real-time clock time is The system default time, if it is the system default time, the current user name and current password of the BIOS Setup can be cleared, and the BIOS chip does not need to be removed from the motherboard to obtain the system default time.
