The F1 to F12 keys of laptops are usually function keys, which can be used to perform specific operations or shortcut keys.If you cannot use these keys, there may be several reasons:

Keyboard settings: Some laptops may set the function keys to enable special functions by default (such as adjusting brightness, volume, etc.), rather than as standard F1 to F12 keys.You can try to activate their standard functions by holding down the "Fn" (function) key and simultaneously pressing the desired F1 to F12 keys.
2. Driver problems: In some cases, incorrect or outdated drivers may cause some or all function keys to fail to work properly.You can fix the problem by updating or reinstalling the appropriate device driver.
3. Software conflict: Some software may occupy and redefine specific function keys, in which case other applications will not be able to use them.You can try to close the relevant software or change its settings to solve the problem.
4. Hardware failure: The last possibility is that some or all function keys fail due to hardware failure.If the above methods are invalid, it is recommended to contact the manufacturer for maintenance and inspection.
In conclusion, please eliminate the above reasons step by step according to the specific situation, and take corresponding measures to solve the problem that F1 to F12 keys cannot be used.If the problem still exists, it is recommended to consult professional technical support personnel for help.
