Why do I need to press F1 to enter the system when I start the computer?

Causes: 1. The floppy drive is turned on in the computer; 2. The first startup item of the motherboard becomes the floppy drive instead of the CD-ROM drive or hard disk, resulting in the system being unable to boot; 3. The motherboard battery is dead or insufficient. The computer's motherboard button battery is lower than 2.6 volts, causing the COMS random access memory to be unable to be saved, resulting in BIOS confusion and the inability to boot the system.

The reasons why you always have to press F1 to enter the system when you start the computer and how to deal with it are as follows:

Cause: This is because the computer has the floppy drive turned on, and the motherboard's first startup item has become the floppy drive instead of the optical drive or hard disk, so the system cannot boot. Another reason is because the motherboard battery is insufficient. This phenomenon will also occur. (Recommended learning: PHP video tutorial)

You can solve it by following the following method:

(1) Chapter One reason: the computer's motherboard BIOS has the floppy drive enabled. Although the computer does not have a floppy drive, the floppy drive function is enabled, so the floppy drive can be disabled. The setting method is as follows: motherboards are divided into two categories:

The first category: (Award 6.0 motherboard) Press DEL or F2 to enter the BIOS after booting, select: DRIVE A in STANDARD CMOS FEATURES: Set to None, DRIVE B: Set to None, press F10 to save, enter "Y" and press Enter. (Different motherboards will vary, but they are more or less the same)

Second type: (AMI 8.0 motherboard) Press DEL or F2 to enter BIOS settings when booting. In the BIOS main interface, use the keyboard direction keys →← to select "Main" - In the Main interface, use the keyboard arrow keys to select "Legacy Diskette A" and highlight it - press Enter - enter the "Options" dialog box - use the keyboard arrow keys to select "Disabled" - press Enter. Press F10 to save, enter "Y" and press Enter.

(2) The second reason: the first startup item of the motherboard is not the optical drive and hard disk, but a floppy drive, and the second startup item is the hard disk. This will also cause the situation where you have to press F1 to enter the system. phenomenon, so you need to set the first startup item to the optical drive or hard disk: Because there are two types of motherboards, the setting method is as follows:

First type: (Award 6.0 motherboard) Press DEL or F2 to enter the BIOS after booting, and find "Advanced BIOS Features---BOOT Device Priority---1St BOOT Device (1ST FLOPPY DRIVE represents the floppy drive SATA: SM-WDC WD5000 represents the hard disk CD/DVD: PS-ATAPI IH represents the optical drive) Just press ENTER here to select CD/ DVD or SATA, then press F10, restart the computer, and you can boot.

Second type: (AMI 8.0 motherboard) Press DEL or F2 to enter the BIOS settings when booting, and find BOOT----boot settings- --boot device priority--enter(OK)--1ST BOOT DEVICE---DVD/CD ROM--enter(OK)) Then press F10, restart the computer, and you can boot.

（ 3) The third reason: the motherboard battery is dead or insufficient. When the computer's motherboard button battery is lower than 2.6 volts, the COMS memory cannot be saved, so the BIOS is confused, causing the first startup item to become The floppy drive is damaged, so the system cannot be booted, and you may also need to press F1 to enter the system.

Solution: Just go to a computer store to buy a motherboard battery (generally the battery model is mainly CR-2032), close Power on, open the main case, remove the old battery, replace the new battery, then press DEL to enter the BIOS, set the first boot as the optical drive and hard disk, close the floppy drive, F10 to save, restart the computer and OK

If none of the above solutions can solve the problem, you can check whether the circuit next to the CMOS has any signs of burnout.
