Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without any creative effort belong to the protection scope of the present application.
The core of the application is to provide a method, a device and a system for clearing BIOS passwords to acquire the current real-time clock time, judge whether the current real-time is the system default time acquired by a BIOS user by taking down a battery of a mainboard to discharge the BIOS system and then reinstalling the battery, and clear the current user name and the current passwords if the current real-time is the system default time, so that the complex operation caused by welding the BIOS chip back to the mainboard after the BIOS chip is taken down from the mainboard and burned again is avoided, and the efficiency of maintaining the BIOS system is improved.
In order that those skilled in the art will better understand the disclosure, the following detailed description will be given with reference to the accompanying drawings.
When the BIOS system is used, information safety consideration is taken into account, a general user can set a user name and a password in a BIOS Setup to protect information safety, after the setting is completed, the user can enter the BIOS Setup and the BIOS system by inputting the password and the user name at first when the user starts up every time, when the user forgets the set password or the user name, the user can only detach a case to take down a BIOS chip for burning again at present, and then reinstalls the BIOS chip, the operation is very complicated, the BIOS chip is directly welded on a mainboard, and the mainboard (rework) needs to be processed after detaching and burning, so that the user can not operate by himself, the maintenance is required by professional personnel, and the mainboard can only be replaced for the user under normal conditions. In addition, if the BIOS chip is repeatedly disassembled and welded, the BIOS chip is damaged, and the service life of the BIOS chip is influenced.
In addition to burning the BIOS chip again, the method of removing the COMS (clear COMS) information by hardware cap-skipping can be used to remove the username and the password set in the BIOS Setup, however, hardware such as a desktop of a godson platform does not have a reserved interface and does not support hardware cap-skipping COMS information, and therefore, the username and the password can still only be removed by burning the BIOS again.
In order to avoid the complicated operation of detaching a BIOS chip to remove a BIOS Setup password, reduce the damage of the BIOS chip and improve the efficiency of maintaining a BIOS system by a user, the embodiment of the invention provides a BIOS password removing method.
Fig. 1 is a flowchart of a method for clearing a BIOS password according to an embodiment of the present invention, as shown in fig. 1, the method includes:
s10: and acquiring the current real-time clock time.
In a specific embodiment, the step S10 may obtain the current real-time clock time each time the BIOS system is started, or may obtain the current real-time clock time when the user starts the BIOS system and inputs a user name and a password with errors, which is not limited in the present invention. Of course, in order to save resources, it is preferable to acquire the current real-time clock time when the user name and password input by the user are wrong. In order to avoid that the user inputs the user name or the password by mistake, the current real-time clock time is obtained by triggering when the user forgets the user name or the password, and the current real-time clock time can be obtained after the user inputs the user name or the password by mistake reaches the preset number.
S11: judging whether the real-time clock time is the default time of the system, and if so, clearing the current user name and the current password; the system default time is the time obtained by switching in the power supply again after the BIOS discharges.
After the current real-time clock is obtained in step S10, it is determined whether the current real-time clock is the default time of the system, and if the current real-time clock is the default time of the system, the current user name and the current password in the BIOS Setup are cleared, where the default time of the system is the time obtained by reconnecting the BIOS after discharging, that is, the default time of the system may be the time obtained by removing the battery on the motherboard by the user so that the BIOS is installed and retrieved after discharging, and the user does not need to remove the BIOS chip and re-burn the BIOS chip to clear the current user name and the current password in the BIOS Setup.
It can be understood that, when the user takes down the battery on the motherboard to discharge the BIOS and then installs the BIOS to obtain the current real-time clock time, the obtained current real-time clock time is an illegal time, that is, the time is not a time within a time range preset by the user, and after the system determines that the obtained current real-time clock time is the 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 detaching and installing the battery.
In specific implementation, when a user forgets a user name or a password set by the user, the battery on the mainboard can be taken down to discharge the BIOS, the battery is installed back after the BIOS discharge is completed, the obtained current real-time clock time is illegal, the system rewrites the real-time clock time to the system default time, namely when the current real-time clock time is the system default time, the BIOS system can be determined to need to clear the current user name and the current password. After the user removes the current user name and the current password of the BIOS Setup by detaching and installing the battery, the system can prompt the user to reset the user name and the password.
It should be noted that the technical solution provided by the present invention is not only applicable to a hardware platform without a reserved interface, such as a loongson platform desktop, but also applicable to any platform, such as a server, a PC, a notebook, and an all-in-one machine.
The method for clearing the BIOS password comprises the steps of obtaining the current real-time clock time of a BIOS system, judging whether the obtained real-time clock time is the default time of the system, and clearing the current user name and the current password of the BIOS Setup if the obtained real-time clock time is the default time of the system, wherein the default time of the system is the time obtained by reconnecting a power supply after the BIOS discharges. Therefore, according to the technical scheme provided by the invention, when a user forgets a set password, the BIOS chip does not need to be taken down and re-burned, the current user name and the current password of the BIOS Setup can be cleared by acquiring the current real-time clock time of the BIOS system and judging whether the current real-time clock time is the default time of the system, if the current real-time clock time is the default time of the system, the current user name and the current password of the BIOS Setup can be cleared, the BIOS chip does not need to be taken down from the mainboard when the default time of the system is acquired, and the user can obtain the current user name and the current password only by taking down the battery of the mainboard for discharging and then reinstalling the battery, so that the user can reset a new user name and a new password, further, the damage to the BIOS chip caused by welding and returning after the BIOS chip is taken down and re-burned is avoided, and the efficiency of maintaining the BIOS system by the user is improved.
In a specific embodiment, after a user takes off a battery on a mainboard to discharge a BIOS, the battery is installed back, and at this time, the current real-time clock time acquired by the BIOS is not within a preset time range, that is, the current real-time clock time is determined to be illegal time, at this time, the system resets the real-time clock time to default time of the system, and after the current real-time clock time is determined to be the default time of the system, the current user name and the current password of the BIOS Setup are cleared. For ease of understanding, the following will be exemplified.
For example, the preset legal time range is 1 month and 1 day in 2000 to 2099 and 12 months and 31 days in 2000, wherein 1 month and 1 day in 2000 is the default time of the system, when the user detaches the battery and waits for the BIOS to be completely discharged and then installs the battery on the motherboard, the current real-time clock time acquired by the system is not within 1 month and 1 day in 2000 to 2099 and 12 months and 31 days in 12 years, that is, the current real-time clock time is determined to be illegal time, and the current real-time clock time is rewritten to 1 month and 1 day in 2000, that is, rewritten to the default time of the system. Therefore, after the system determines that the current real-time clock time is the default time of the system, the current user name and the password are cleared.
For the preset time interval, namely the legal time, the user can set the time interval by himself according to the preference, or the system can be updated regularly according to the current time. For example, the predetermined legal time range is from 1/month 1/year 2000 to 2099/year 12/month 31/year, and the legal time range may be updated to 1/month 1/year 2003 to 2102/month 12/month 31/year after 3 years, but the present invention is not limited thereto.
The method for clearing the BIOS password provided by the embodiment of the invention firstly judges whether the current real-time clock time is illegal or not between the judgment of whether the current real-time clock time is the default time of the system or not, rewrites the current real-time clock time to the default time of the system if the current real-time clock time is the illegal time, otherwise, normally starts the BIOS system, therefore, a user can achieve the purpose of obtaining the default time of the system by disassembling and installing a battery, namely, the purpose of clearing the current user name and the current password of the BIOS system is achieved by disassembling and installing the battery.
On the basis of the embodiment, in order to avoid resource waste caused by the fact that the user also acquires the current real-time clock time when remembering the user name and the password, before the current real-time clock time is acquired, whether the current password input by the user and/or the current user name are/is wrong is judged, if yes, it is determined that the user forgets the current user name and the current password, the current real-time clock time is immediately acquired, whether the current real-time clock time is the default time of the system is judged, and if the current real-time clock time is the default time of the system, the current user name and the password are removed.
Before judging whether the current real-time clock time is the default time of the system, the method for clearing the BIOS password firstly judges whether the current real-time clock time is illegal time, namely whether the currently acquired real-time clock time is the time within a preset time interval, and rewrites the current real-time clock time to the default time of the system if the current real-time clock time is the illegal time, so that the aim of clearing the current user and the password of the BIOS is fulfilled, the complex operation of taking down a BIOS chip from a mainboard and burning the BIOS chip again after installation is avoided, and the service life of the BIOS is prolonged.
On the basis of the above embodiment, considering that the user may input an incorrect user name or password by mistake, if the current real-time clock time is obtained once the user has input an incorrect user name or password, resource waste may be caused, and a bad experience may be brought to the user.
It should be noted that when the user inputs the wrong user name and password and the wrong times do not reach the preset times, the system prompts the user to re-input the current user name and password, when the wrong times reach the preset times, the system prompts the user that the input times reach the upper limit and then input after asking for the preset time, or prompts the user that the input times reach the upper limit and then reset the password. The present invention is not limited to the contents of the hint.
According to the BIOS password clearing method provided by the embodiment of the invention, when the number of times of error user name and/password input by a user reaches the preset number, the step of obtaining the current real-time clock time is carried out, so that whether the current real-time clock time is the default time of the system or not is judged, whether the current user name and the current password need to be cleared or not is determined, and if the input user name and the input password do not reach the preset number, the BIOS system is normally started without obtaining the current real-time clock time, so that unnecessary operation caused by obtaining the current real-time clock time when the user inputs the error time by mistake is avoided, the waste of data is caused, and the maintenance efficiency of the BIOS system is further improved.
In a specific embodiment, after completely discharging the BIOS by detaching the battery on the motherboard, the user installs the battery back to the motherboard, and the current real-time clock time obtained at this time is illegal time, that is, the current real-time clock time is not time within a preset time interval, and rewrites the current real-time clock time to system default time, and when it is determined that the current real-time clock time is the system default time, clears the current user name and the current password of the BIOS Setup. After clearing the current username and password, the system may prompt the user to reset the new password and username.
According to the method for clearing the BIOS password provided by the embodiment of the invention, when a user forgets the set password, the BIOS chip does not need to be taken down and burned again, the current user name and the current password of the BIOS Setup can be cleared if the current real-time clock time of the BIOS system is the system default time by acquiring the current real-time clock time of the BIOS system and judging whether the current real-time clock time is the system default time, and the BIOS chip does not need to be taken down from the mainboard if the current real-time clock time is the system default time, and the user can obtain the BIOS Setup only by taking down the battery of the mainboard for discharging and then reinstalling the battery, so that the user can reset a new user name and a new password.
