What is the use of pressing from F1 to F11 when booting up? When exactly to press it? 20

What are F1 and F12 used for? All keyboards have at least 12 function keys, often referred to as the F key, which are generally located at the top of the keyboard, from F1 to F12.

F1: If you are in a selected program and need help, press F1. If you are not in any program, but in Explorer or on the desktop, press F1 and the Windows helper will appear.

If you're working on a program and want to get help from Windows, you'll need to press Win F1. Press shift+f1 and it will appear"what"s this?"for help information.

F2: If a file or folder is selected in Explorer, pressing F2 will rename the selected file or folder.

F3: Press F3 in Explorer or on the desktop, and the "Search Files" window will appear, so if you want to search for files in a folder, then press the F3 key directly to quickly open the search window, and the search scope has been set to that folder by default. Similarly, press it in Windows Media Player and a window that says "Add to Library by Searching for Your Computer" will appear.

F5: Used to refresh the contents of the window currently in IE or Explorer.

F7: Doesn't work in Windows. But in the DOS window, it works, give it a try!

F8: You can use it to display the boot menu when you start up your computer. Some computers can also press this key at the beginning of the computer boot to quickly bring up the boot settings menu, from which you can quickly choose whether to boot on a floppy disk, a CD, or directly with a hard disk, without having to go into the BIOS to modify the boot sequence.

In addition, it is possible to accept Microsoft's installation agreement when installing Windows.

F9: Again it doesn't work in Windows. But in Windows Media Player, it can be used to quickly lower the volume.

F10: Used to activate the menu in Windows or programs, pressing Shift F10 will bring up the right-click shortcut menu. The application key in the keyboard functions the same.

Whereas, in Windows Media Player, its function is to increase the volume.

F11: You can make the current explorer or IE full-screen.

F12: Again it doesn't work in Windows. But in Word, pressing it will quickly pop up the Save as File window.

F1 Some computer systems need to be pressed when booting.

F8 is a safe mode boot. (There are some options to go in, what is disconnected to enter the safe mode, and the network is entered).

f11 is a restore (if the restore wizard is installed).

The corresponding buttons of different brands of motherboards are different, but generally only F1, F2, F10, F12, F8, F9, F1 seem to be used by IBM, and enter the motherboard CMOS parameter change. F2 is used by most old notebooks, and F10 motherboards in Taiwan are used more, and the functions are as above. F8 is the safe mode, (including safe mode, VGA mode, safe mode with network connection, safe mode with command prompt, etc.) F12 is generally the key to select advanced boot items, and the functions of F9 and F10 are; After changing the CMOS parameters of the motherboard, F9 exits without saving the modification, and F10 exits with the modification of saving.

For a deeper understanding, look for answers in the evening, and he will make you more fulfilling.

What needs to be Ann He has hints below.

You just need to know that the del is into the blos

F8 is the one that shows the boot menu.

When the second screen appears when the boot appears, what is the specific function of the first floor has been given;

Computer boot press F11 is the role of booting into the safe mode, computer (computer), commonly known as computer, is an electronic computer machine used for high-speed calculation, can carry out numerical calculation, and can carry out logical calculation, but also has the function of storage memory. It is a modern intelligent electronic device that can operate according to the program and process massive amounts of data automatically and at high speed. A computer that consists of a hardware system and a software system without any software installed is called bare metal.

It can be divided into five categories: supercomputers, industrial control computers, network computers, personal computers, and embedded computers, and the more advanced computers include biological computers, photonic computers, quantum computers, etc. x0d x0a more about what is the use of pressing f11 when the computer is turned on, enter to see more content.

You need to press the F1 key to enter the boot, mainly because the settings in the BIOS do not match the real hardware data, which can be divided into the following situations:

1. In fact, there is 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. It turns out that there are two traveler hard disks, and they are set up as dual hard disks in the BIOS, but when they remove one of them, they forget to change the BIOS settings back, which will also cause this problem.

3. If the motherboard battery is out of power, it will also cause data loss, which will cause this failure.

4. Reboot the system, enter the BIOS settings, and find that the floppy drive is set to 1 44M, but in fact there is no floppy drive in the chassis.

1. The CMOS parameter settings are incorrect

Floppy drive: If the floppy drive is not detected, please check whether the data cable is connected, and then see if the settings in the BIOS are correct: check the settings of the boot sequence; In addition, if there is no floppy drive, it is directly shielded.

Keyboard: Some CMOS settings in the keyboard problem will also appear press F1 to boot the situation, the landlord to check it himself.

Memory: Disable Memory Verification.

2. Prompt for insufficient BIOS battery power - replace the battery 3. Jumper setting problem - refer to the manual to set.

If you can't start AGP acceleration, the performance of the graphics card will be reduced by 60%.

Restore the BIOS settings and you're done! Generally, press del when you boot up, press f5 to restore the settings after entering, and finally press f10 to save, and then restart.

There are two reasons for this.

1. Your CMOS battery is dead, 2. It's a setting problem in the BIOS, you just turn off the floppy drive start.

Have you ever encountered the phenomenon of pressing f1 or f2 when the computer is turned on, and you have solved such a problem in this way. Today we're going to teach you how to turn off this pesky F1 key.

It will be prompted every time it is turned on.

And you must press the shortcut key F1 before the computer can start normally.

Reasons and solutions for secondary failures:

1. The battery on the motherboard is dead.

Solution: Replace the motherboard battery.

2. You have set up the floppy drive to start, but there is a problem with your floppy drive.

Solution: A. Press del to enter the BIOS at boot, boot up the boot sequence, and turn off the floppy drive to boot.

b. Turn off the detection function of the floppy drive when it is turned on

Start the computer and press the [DEL] button to enter the main BIOS settings interface.

Select "Advanced."

biosfeatures", press the enter key to enter;

Add "boot

upfloppy

seek" is set to "disabled", so that the boot software detection function can be turned off, and there is no need to press F1 to start it in the future.

Press the F1 key on boot, this is because you don't have a floppy disk drive installed, but in CMOS you have set the option to turn on the floppy drive.

The method is: press the DEL button on power, enter the BIOS settings, and select the first one"Basic settings", I didn't set the floopy one"disabel"It's okay to be invalid.

It should be because the boot detection floppy drive is not found, and the boot detection floppy drive can be canceled:

1.Press the power button to turn on (it is important to keep your eyes open, and you can't set it if you don't turn it on 2. Keep pressing the "del" button when you turn it on.

3. Go to the first item of BIOS settings.

4. Use the naked eye to find the "About" option, and select it with the cursor key after finding it.

5. Click Enter to change to "none", or use the page turn key to select and change to "none".

6. Press F10, and then click "Y" (some machines press the Enter key) to automatically restart.

Supplement: If your machine also has the following problem: the time returns to zero every time you turn it on.

Time zero is the CMOS battery is dead. If you have bought your machine for less than two years, find a dealer to replace the power supply, and if it is more than two years, buy a CMOS battery yourself (it may be that the battery is aging). Power failures generally appear when the power supply is turned on, you must press F1 to turn it on, shut it down for more than 2 hours, and then turn it on for more than 2 hours.
