Why do I need to press F1 when the computer is turned on, and how to get it off

Press F1 when booting up. This is because your BIOS settings are improper but you can boot the system normally. This is a non-fatal failure. Pressing F1 is asking you if you want to continue.
This situation is generally caused by the boot detection of the floppy drive, and the sudden power failure or crash of the computer caused by the BIOS setting error.

Solution:

1. After booting, press the DEL key to enter the CMOS. After entering, press the Enter key (Enter key) under the "Standard CMOS Featrues" directory, and you

will see the following screen: Change the value of "Floppy Drive A" to off, and set "Hold on The value of "is changed to "No Error".

After that, press F10 to save and exit.

Method 2:
Press the F1 key when booting. This is because your BIOS settings are improper but you can boot the system normally. This is a non-fatal failure. Pressing F1 is asking you whether to continue.

You have not installed a floppy drive, but set it in CMOS, and turn on the floppy drive option.

The method is: power on, press the Del key, enter the BIOS settings, select the first "basic settings", and set the floopy setting without "Disabel" invalid.

2 Press DEL to enter the BIOS at the beginning of booting, press Enter to enter the first item, and see if the "Drive A" item inside is "None", if not, press "Pgup" or "PgDn" to modify, and then press "ESC" to exit, select the "Save & Exit Setup" item and press Enter to exit the BIOS, restart, and if it doesn't work, change the battery and reset the settings according to the above steps.

3 You need to press the F1 key to enter when booting up. It is mainly caused by the inconsistency between the settings in the BIOS and the actual hardware data. It can be divided into the following situations:
1. There is actually no floppy drive or the floppy drive is broken, but there is a floppy drive in the BIOS. , Which leads to pressing F1 to continue.
2. Originally, two hard disks were hung up and set to dual hard disks in the BIOS. Later, when one of them was removed, but the BIOS setting was forgotten to change back, this problem would also occur.
3. If the motherboard battery is out of power, it will also cause data loss and this failure will occur.
4. Restart the system and enter the BIOS settings. It is found that the floppy drive is set to 1.44M, but in fact there is no floppy drive in the chassis. After setting this item to NONE, the fault is eliminated.
Many people have asked this kind of question before. Here is a summary of the kind of question I have encountered, and I hope it will be helpful to everyone.
1. Hareware Monitor found an error, enter POWER MANAGEMENT SETUP for details, Press F1 to continue, DEL to enter SETUP

Chinese: When the monitoring function finds an error, enter POWER MANAGEMENT SETUP to view the detailed information, press F1 to continue the boot process, and press DEL to enter COMS settings.

Explanation: Some motherboards have hardware monitoring functions, which can set the temperature monitoring of the motherboard and CPU, the voltage output level monitoring of the voltage regulator, and the monitoring of the speed of each fan.

When the above monitoring function finds an abnormal situation when it is turned on, then the above paragraph will appear. At this time, you can enter the COMS setting and select POWER MANAGEMENT SETUP, and check which part of the Fan Monitor , Thermal Monitor and Voltage Monitor on the right is abnormal. Then solve it.

2. The pri slave drive-ATAPI LNCOMPatible press F1 to Resume
may be that your CD-ROM drive is not connected well or is faulty. It is best to set each IDE port to automatic in CMOS.

3. Press F1 to continue, DEL to enter SETUP
after booting, press DEL to enter the BIOS, select NONE in the floppy drive, and then press F10 to save.

4. CMOS checksum error-Defaults loaded
Press F1 to contnue? DEL to enter SETUP
08/09/2000-i810-ITE8712-6A69ME1CC-00
cmos battery is dead.
5. Warning! CPU has been changed! Please Enter CPU speed CMOS setup and Remember to save Before Exit!
This shows that the BIOS settings have been washed away, and you need to reset the BIOS (also called CMOS settings). Turn on and hold down the "Del" key to enter the settings, see your motherboard manual. What is your CPU frequency? The FSB must be selected in the BIOS, and the multiplier is locked anyway. The FSB is always 66, 100 or 133, depending on the CPU model, set from low to high. If it is the BIOS setting of AWARD, select Frequency/Voltage Control (Frequency/Voltage Control) on the home page. Use this menu to make special settings for frequency and voltage. Among them, "Clock By Slight Adjust" allows you to select the CPU clock frequency. The BIOS settings of various motherboards are different, you can refer to your own motherboard manual to adjust.
6. cpu has been changed please re-enter cpu settings in the cmos setup and remember to save before quit!
Some motherboards have an external frequency jumper, the default is 100MHZ, and some motherboards do not support automatic frequency modulation. You just need to enter the BIOS Just set the FSB to the standard FSB of your CPU. The multiplier is usually set automatically, and it is best not to overclock.

If none of the above solutions can be solved, you can check whether the circuit next to the CMOS has burnout signs. My friend has a problem with the circuit next to the CMOS. Haha, you might as well try it too!
