As we all know, PC Power-on, the first to start the BIOS on all hardware testing, when your hardware and the original CMOS parameters do not meet, or CMOS parameters lost, system instability, you need to enter the CMOS settings, reconfigure your system configuration. So, how to enter the CMOS in the notebook computer to set it?
First, enter the CMOS settings
The
laptop also has CMOS settings, but the way it goes in the CMOS settings is very different from the desktop. When the notebook computer boot up, you press the DEL key is not able to enter the CMOS settings, many brands of notebook computers, you need to press F2 key to enter the CMOS settings. This is mainly to see what your host is using the BIOS, because different BIOS has different access methods, but the general notebook computer will be in the boot screen prompts.
The following is the current brand notebook computer into the CMOS settings method:
IBM laptops into the BIOS: (Cold boot Press F1, part of the new number can be restarted when the press F1)
HP Laptops Enter the BIOS: (press F2 on startup and reboot)
Dell laptops into BIOS: (press F2 on startup and reboot)
Acer Laptops Enter the BIOS method: (Press F2 on startup and reboot)
Compaq laptop into the BIOS method: (Boot to the top right corner of the flashing cursor when the F10, or on the Boot press F10)
the way in which most domestic (including Chinese Taiwan) branded laptops Enter the BIOS: (press F2 on startup and reboot)
two, set up notebook computer BIOS password
because most laptops are portable, it is necessary to use passwords to prevent others from stealing computer data.
The BIOS password for the notebook computer is generally divided into the user password (users pass video tutorial ' >word '), the Super User password (Supervisor Password) and the hard disk password (Hard disk Password), some of which have a special set password. These passwords are usually stored in a special cipher chip, or written in a flashrom. Both the power-on password and the superuser password restrict access to the system, except that the super password has the right to completely modify the BIOS settings and the user password is not available. In short, if you are entering the BIOS with a user password, some items will become unavailable. Because the notebook computer is mostly its own use of more opportunities, so it is recommended to use the Super password for notebook computer lock, both to protect the computer security, but also have all the permissions. Only if you set the Super password, the password must be kept in mind, if you forget the password that would be terrible, it is very likely that "motherboard scrap", even if you go to the manufacturer to help, their solution is mostly a new motherboard.
the method of setting the Super Password is: www.3lian.com
1, turn on the power, press the F2 key into the BIOS;
2, switch to "security";
3, then move the cursor to "Set supervisor Password";
4, enter the password to be set;
5, then "Spervisor Password Is:set", indicating that the password has been set to complete;
6, finally the "Password on Boot" option set to "Enable", set the boot must enter the password before the line, all the settings are done.
when we reboot again, notebook computer will not go directly into Windows, but first require you to enter the password, enter the correct password, the computer can successfully complete the boot, input errors can be retried, but more than 3 times the system will completely deadlock, at this point must shut down the computer and then reboot.
Three, open antivirus function via BIOS
In recent years, computer virus activity is rampant, virus is also a dazzling array of species, countless. In a computer virus is called a startup virus, it will be in the boot of the memory, and damage to the start sector, resulting in a small loss. In recent years, however, the launch virus has not been as strong as it used to be, largely because the NTFS file format used by most of the 2000 systems has been able to generate effective defenses when it comes to initiating virus attacks.
If your laptop is a win 9x/me system, you will need to start a laptop BIOS antivirus function to protect against the launch virus attack. First enter BIOS setup:
1, switch to the "Security" tab;
2, the "Boot sector Virus Protection" project set to "Enabled" can be.
turn on this feature, then if there is a startup virus attempt to destroy the start sector, the BIOS will be aware of this operation, and in the screen display "There is a program to rewrite the start sector" message, then you just press the N key to refuse, you can.
four, the BIOS to open the power-saving function and calibration battery
for people using laptops, the battery time has always been a matter of considerable concern to users, in the absence of external power, the average use of notebook computer about 2-4 hours, although to deal with a meeting or briefing is enough, but if you want to work more than three or four hours, Half the time, there will be a lack of power warning, if there is no backup batteries around, the work can not continue.
in fact, in the absence of external power supply, we can through some power-saving skills to extend the use of notebook computers, the following we set up in the bios of the LCD power, so that the notebook computer in the absence of external supply, slightly weaken the LCD screen brightness, so that, will not affect the picture output quality, but also can prolong the use time of the notebook computer:
1, first enter the BIOS settings, and then switch to the Power tab
2, when you move the cursor to the "LCD power saving" option, press the "Enter" key to set
3, set the option to "Enabled" to use the battery correction function to restore the battery charging efficiency
When the laptop is in use for some time, most users will also feel that the battery is used more and more short, in fact, this is because the notebook battery in the process of continuous charging, discharge, and sometimes the BIOS will detect the power, and the actual battery power does not match, in this case, although the battery has a little power, However, the BIOS will determine the power consumption, and then into the shutdown state.
in order to solve this problem, some manufacturers have included in the notebook BIOS "battery correction (Battery calibration)" function, to help users to fill the laptop battery, and then discharge to complete no power, and then filled again, So for the long-term not complete discharge caused by the electricity error, there is a certain correction effect.
1, first enter the BIOS settings, switch to the "Power" tab.
2, then move the cursor over the "Start Battery calibration" option and press the "enter" key to execute.
3, according to the message, the laptop computer to connect the external power supply, and wait for a period of time to fill the battery charge.
4, when the screen appears "please remove AC adapter" information, indicating that the power has been full, and then discharge operation, unplug the external source, and let the notebook computer continue to boot until the battery runs out. Note: This operation will take some time, you can do some other work, wait until the discharge is completed and then return operation.
5, after the battery discharge and automatic shutdown, do not turn on the notebook computer power, and then connected to the transformer to recharge, wait until the charging indicator (usually orange lamp) off, the battery correction work is done.
in general, the battery has a service life, batteries that use too much time are naturally low, so there's no guarantee that this method will definitely restore the battery's storage capacity, but if your battery is used soon enough, you may want to try using this feature to restore battery storage.
Note: Battery correction operation can not be too frequent, otherwise the regular discharge will make the battery life shorter, recommended six months to correct.
