Question 2: How to set the BIOS BIOS, that is, the basic input and output system, after the motherboard is discharged? Setup program is a set of programs solidified in CMOS chip on the computer motherboard, and its main function is to provide the lowest and most direct hardware setup and control for the computer. The BIOS can only be set at startup. Mainly to manage and set up the basic input and output system of skills, so that the system can run in the best state. Use the BIOS setup program to troubleshoot or diagnose system problems.
At present, there are three main types of motherboard BIOS, namely AWARD AMI and PHOENIX. But Phoenix has merged with AWARD.
? After starting or restarting the computer, when "CD……" is displayed on the screen, press the "Del" key to enter the BIOS setting interface. If you press it too late, the computer will start the system, and then you have to restart the computer. After entering, you can use the direction keys to move the cursor to select the setting options, then press Enter to enter the submenu, use ESC to return to the parent menu, use PAGE UP and PAGE DOWN to select specific options, and use F 10 to save and exit the BIOS settings.
Novices must not modify their option settings at will when they are unfamiliar. In general, you can use the following options to restore and optimize your computer:
prize
Load BIOS default value, which is used to load initial BIOS settings and determine the fault range.
Load the OPRIMUM settings (load the motherboard BIOS factory settings), which is the factory BIOS optimization settings.
Or AML
Load BIOS settings defaults. This option is used to load the BIOS initial settings.
Load high performance default values, which are used to load BIOS optimization settings.
Use the keyboard direction keys to select the initial value or optimization value, then press ESC, press F 10, Y, press Enter, or select Save &; Exit Settings (Save and Exit Settings), save the changed settings and exit BIOS settings.
Of course, through learning, you can naturally set and change the options you want to set.
Question 3: How to restore the factory settings after the motherboard is discharged? First, unplug the power cord of the host. On the motherboard, there is a button-shaped battery (the same shape as the battery in the electronic watch, but much larger, the size is similar to the button of clothes, made of metal). It is installed in the pocket, and there is a mechanism to take out the battery next to the pocket. Pull aside and take out the battery, or pry it out with a toothpick. After 5 minutes (or more), put the battery back as it is and install the power cord. Press Del key to enter BIOS settings after booting. There is a default value for loading BIOS in BIOS, which is set by the factory. Just select it, and then select Save. Good luck!
Question 4: What is the setting after the battery of the computer motherboard is discharged? 1. Use CMOS discharge jumper.
For most motherboards at present, CMOS discharge jumper is designed for the convenience of users' discharge operation, which is the most commonly used CMOS discharge mode (the following methods 2, 3 and 4 and the methods in the summary are basically not used). Generally, the discharge jumper is three pins, located near the socket of the motherboard CMOS battery, with battery discharge instructions (some are two pins, such as Huaqing motherboard, also located near the motherboard CMOS battery, with CLRCMOS logo, and the two pins directly contact with conductive objects for one or two seconds to discharge successfully). In the default state of the motherboard, the jumper cap will be connected to the pins marked with "1" and "2", which can be known from the discharge description as "normal", that is, the normal use state.
When using this jumper to discharge, firstly use tweezers or other tools to pull the jumper cap out of the "1" and "2" pins, and then put it on the pins marked with "2" and "3" for connection. From the discharge instruction, we can know that the state is "clear CMOS", that is, Clear CMOS (as shown in the figure below). After a short (one second, it doesn't matter at all) contact, you can clear the user's manual settings in the BIOS and return to the default settings when the motherboard leaves the factory.
According to the discharge description of jumper, CMOS discharges.
After the CMOS is discharged, the jumper cap needs to be removed from the "2" and "3" pins, and then restored to the original "1" and "2" pins. Note that if the jumper cap does not return to the normal state, the computer will not start and will give an alarm.
2. Take out the CMOS battery
I believe many users have encountered the following situations: to discharge CMOS, but the jumper of CMOS discharge can't be found on the motherboard (such as ASUS motherboard). What should I do? At this time, CMOS can be used to supply power to the battery to achieve the purpose of discharge. Because the power supply of BIOS is supplied by CMOS battery, the power supply of BIOS can be cut off by taking out the battery, thus clearing the self-setting parameters in BIOS.
Find the CMOS battery socket on the motherboard, and then press the card on the socket to one side. At this time, the CMOS battery will pop up automatically, so take it out carefully.
Press the buckle aside and the battery will pop up automatically.
Then turn on the host power to start the computer, and the screen will prompt that the data in the BIOS has been cleared and needs to be reset in the BIOS. This can prove that CMOS has been successfully discharged.
When the BIOS starts, it prompts an error, which proves that the discharge is successful.
3. Short the positive and negative poles of the battery socket.
Although the method of taking out the power battery to discharge CMOS has a certain success rate, it is not omnipotent. For some motherboards, even if the power battery is taken out for a long time, the purpose of CMOS discharge cannot be achieved. In this case, CMOS needs to be discharged by short-circuiting the positive and negative poles of the battery socket. Of course, on the motherboard with CMOS discharge jumper, this method can also be used if CMOS discharge operation is too troublesome.
CMOS battery socket is divided into positive electrode and negative electrode, which can be discharged through short circuit. First, take out the CMOS power battery on the motherboard, and then short-circuit the positive and negative electrodes on the battery socket with conductive objects (such as screwdrivers and tweezers) (as shown in the figure below), so as to achieve the purpose of CMOS discharge.
Short-circuit the positive and negative poles of the battery socket with conductive objects.
4. Change the hardware configuration
In addition to the above three methods, you can also try to clear the password set in the BIOS by changing the computer hardware configuration. Because at startup, if the system finds that the current hardware configuration is different from the original hardware configuration, it may automatically enter the BIOS setup screen for the user to reset, without entering a password.
For example, if the parameter of the hard disk is set to "user" in the BIOS, you can remove the hard disk and restart the BIOS ... >; & gt
Question 5: How to set CMOS after the motherboard is discharged? 1. Restore the state before hardware replacement and check whether the system can be started normally.
2. Check whether all cables or expansion cards are connected correctly.
3. Try to reconfigure PNP/PCI Configuration and Reset Configuration Data in the BIOS. You can also set it to "Enabled" by using BIOS options, such as "Force Update of ESCD", and then save and exit. If it can't start, try setting it to Disabled again.
4. For information about CMOS jumper and clearing CMOS, please refer to the motherboard manual. Please note: When clearing CMOS settings, you must unplug the host power cord or set the host power switch to off or 0.
5. Disconnect the hard disk cable, including the CD-ROM drive or other IDE devices, then enter the BIOS settings, select floppy disk as the startup sequence, press F 10 to save and exit, and then put the bootable system disk in the floppy disk drive to check whether the system can be started normally.
6. After clearing the CMOS settings, set the "PNP/PCI Configuration" option in the CMOS settings to "Enable" and restart the computer again to update the DMI data, which is also called forced update of the ESCD data.
7. If the host can be started by floppy disk, but not by hard disk, this situation may be that the data in the main boot area of hard disk is destroyed. At this time, you can use partition software to repair the program code of the main boot area, for example, after starting the computer with a floppy disk, use the FDISK/MBR command to repair the main boot area. You can also download a special hard disk analysis tool program from the website of the corresponding hard disk manufacturer to check the specific failure of your hard disk.
8. If the fault cannot be eliminated after the above settings, the IDE interface problem of the motherboard or hard disk should be considered at this time, and it can be solved by replacement.
Question 6: How to set the motherboard after discharge? If the system time is incorrect, change the time after entering the system normally. Do it.
After the bios is uninstalled, it will automatically load the default optimal settings.
Question 7: How to set the bios after the computer motherboard is discharged? After the BIOS is discharged, it will return to the factory. Generally, it can be used without setting. If you have a SSD, open an interface ahci, and don't move anything else.
Question 8: How does the computer motherboard discharge? Remove the battery from the motherboard and short-circuit the positive and negative electrodes in the battery slot. In fact, just use two iron plates to touch the battery vertically in the battery tank a few times.
Question 9: How to set up the computer after replacing the motherboard battery? There is no need to change bios settings after replacing the motherboard battery. Just press F 10 and press Enter twice.
1) The bios setting has not changed, and the BIOS will adapt.
2) The BIOS settings have been changed before, so it is necessary to restore the BIOS to the factory settings.
3) If you are prompted to press F 1 when starting the machine, you can press F 10 and press Enter twice.
Question: How to set the BIOS after it is discharged and turned on? To determine the problem.
The general meaning of the award BIOS ring * * * is:
1 short: the system starts normally. This is what we hear every day, which also shows that there is nothing wrong with the machine.
2 Short: General error, please enter CMOS settings and reset incorrect options.
1long1short: Error in RAM or motherboard. Try to change your memory. If it still doesn't work, we will change the motherboard.
1 long 2 short: monitor or graphics card error.
1 Length 3 is short: keyboard controller error. Check the motherboard.
1 length 9 short: the Flash RAM or EPROM of the motherboard is wrong, and the BIOS is damaged. Try changing the flash memory.
Constant ringing (long sound): The memory module is not tightly inserted or damaged. Reinsert the memory stick. If it still doesn't work, you need to change a memory.
Non-stop ringing: the power supply and monitor are not connected to the graphics card. Check all plugs.
Repeated short tone: power problem.
No sound, no display: power problem.
AMI BIOS ring * * * roughly means:
1. A short sound, memory refresh failed. The memory is badly damaged. I'm afraid I have to replace it.
2. Two short tones, memory parity error. You can enter CMOS settings and turn off the memory parity option, that is, set it to disabled. Generally speaking, however, the memory stick has parity, and the parity is turned on under the CMOS setting, which is beneficial to the stability of the microcomputer system.
3. After three short sounds, the system basic memory (1 64Kb) failed to be checked. Replace the memory.
4. Four short tones, system clock error. Repair or replace the motherboard.
5. Five short sounds, CPU error. But it is not necessarily the fault of the CPU itself. It is also possible that there is something wrong with the CPU socket or other places. If this CPU is normal on other motherboards, the fault must be the motherboard.
6. Six short tones, keyboard controller error. If the keyboard is not plugged in, it is very simple, just plug it in; If the keyboard connection is normal but there is an error prompt, try a good keyboard; Otherwise, there is something wrong with the keyboard control chip or related parts.
7. Seven short tones, system real mode error, unable to switch to protection mode. This is also the fault of the motherboard.
8. Eight short tones, indicating memory reading and writing errors. The memory module on the video card may be damaged. If the memory module is pluggable, just find out the bad chip to replace it, otherwise the graphics card needs to be repaired or replaced.
9. Nine short sounds, ROM BIOS check error. Try to change a good BIOS of the same type. If it proves that there is something wrong with the BIOS, you can try to recover it by rewriting or even hot plugging.
10. Ten short tones, register read/write error. Only the motherboard can be repaired or replaced.
1 1 .11 short tones, cache error.
12. If you can't hear the beep and see the screen display, first check whether the power supply is connected properly. Maintenance is often easy to neglect, and the test is started without connecting the motherboard power supply. Secondly, it depends on whether there are any missing components, such as CPU and memory chips. Similarly, unplug all the cards in question and try only the video card. Finally, find the jumper on the motherboard to clear the CMOS settings, clear the CMOS settings, and restore the BIOS to the factory state. If there is nothing wrong with the monitor, graphics card and wiring, and there is nothing wrong with the CPU and memory, after the above steps, the microcomputer still doesn't display or ring * * * when it is turned on, then there can only be something wrong with the motherboard.
