Sooner or later, on almost any computer, when you turn it on, you need to press the F1 or F2 key. If this is not done, it simply will not turn on, remaining hanging on a black background with white letters. In this article we will tell you what this means, as well as how to get rid of the constant pressing of the F1 button when turning on the computer.
Why does the computer ask to press F1?
There are several possible reasons why you need to press the F1 button every time you turn it on. Thus, the system draws the user's attention to the existence of a problem. Always just above the line "Press F1 to continue" there is a message that caused the request to press F1. Now we will look at all the possible options.
Cmos checksum bad / CMOS Checksum Error
Error loading Cmos checksum bad
Smart status bad backup and replace / Immediately backup your data and replace your hard disk drive
If there is a similar phrase before the phrase "Press F1 to continue", it means that HDD is in poor condition. As, it is recommended to immediately copy important data to another hard drive and replace the current one.

Chassis intruded!
If the BIOS tampering option is enabled, then the message "Chassis intruded!" Will be displayed. You just need to enter BIOS settings and disable.
Chassis intruded! Fatal Error… System Halted
Intel cpu ucode loading error
This message indicates processor compatibility issues and motherboard... Most likely a motherboard BIOS update is required. Learn more about the error in.
Often, error pop-ups can be very annoying, especially if it is repeated systematically. But there is a special kind of failure in the operation of technology, which manifests itself in the fact that the computer is started through f1.
Without this seemingly simple action, nothing will happen further, and therefore the owner simply has no choice but to press the button every time it is turned on. But, if you know the reason and have some skills in handling technology, then you can solve the problem in order to avoid unnecessary waste of nerves in the future.
At first glance, there are two main reasons why such a failure occurs:
1.
Replace the battery on the motherboard.
In addition to the need to press the f1 button every time you turn it on, another main symptom that you need to replace the battery is the incorrect display of the computer's system time. When the computer is started through f1, replacing the battery is sufficient simple method solutions to the problem, since if you have at least a little knowledge of computer technology, it is possible to independently make a replacement.
However, otherwise, you need to seek help from specialists. But, first, you can try to solve this difficulty in a different way. To do this, you need to remove the battery from the motherboard and return it to its place after 10-20 minutes. During this time, the capacitors' charge will drop, and the BIOS settings will return to the factory settings. This means there is a chance that the problem will disappear. On fairly old computers, the discharge time of the capacitors can take a couple of hours.
2. Indeed, in the overwhelming majority of cases, when computer boots from f1 , the reason is the need to replace the battery. But there is a small percentage of situations where solving the problem is not so easy. This requires at least basic knowledge of BIOS. In what cases can a failure of its settings lead to the fact that when loading it is required to press f1? For example, there is a problem with the fan on the processor.
However, it may not work at all or work at a significantly slower speed. If recently the fans were cleaned with their removal, then perhaps after that one of them was incorrectly connected. If the check showed that the fan on the processor is connected correctly, then there may be problems with the connection wires. Further, a failure in BIOS settings can occur when the motherboard "does not see" the keyboard. Here, either the plug really came off, or there is a difficulty in the serviceability of the hardware. Another reason for launching through f1 may be an incorrect setting in the BIOS, when the priority loading of the operating system is configured on a different disk than it should. For example, when drive A is specified, which may be completely absent as unnecessary. In this case, you need to go to the BIOS settings and specify the correct path to boot the system. As an additional symptom the computer hums when booting stronger than usual.
And so I add another solution to the problem
When loading, a window appears with the inscription CPU fan error press "F1" on the monitor, press the "F1" key and the operating system continues to load, since this error is not considered critical. I have encountered a similar task and I cannot say that the solution was the same, but first things first, I will give you all the solutions I know of the solution to this problem.
CPU fan error press "F1"
Of course, such a warning is related to the processor fan and first of all you need to pay attention to it. We make sure that the processor fan power plug is inserted into its connector on the motherboard with the name "CPU Fan", because there are several more connectors with the word "Fan", for example, "Chassis Fan" and "Power Fan Speed" selling computers.
The fan should rotate freely, without any accompanying sounds. There should be no dust on the processor heatsink.
Many power users on error " F1 "check the performance of the fan and, making sure that it is working, turn off this error in BIOS , for example, in the section “ Fan Monitor ", in the" CPU fan speed "- set the value" ignore ”And the motherboard stops tracking the CPU fan speed.
So that it does not burn out at an outrageous temperature, we can only hope for an emergency shutdown of the computer or we need to use programs that monitor the temperature of components inside system unit.
Also, many simply set the "Wait For" F1 "If Error" parameter in the BIOS to Disabled
Disabled
Sometimes motherboards have 4-pin connectors for connecting a processor fan, a 3-pin fan is inserted into them, this is a little wrong and in many cases leads to a similar error - CPU fan error press "F1".
And sometimes the motherboard has only one connector for connecting the processor fan and nothing is inserted into it at all, naturally our error will occur. You may ask: "Where is the processor cooler connected?" It's a good question, just such a case came across to me recently, and not somewhere, but in a government institution. To my question: - "How long has your computer been asking you to press F1 when you turn it on?" They answered me: - "As soon as it was brought, we press it, but it was brought a year ago." We remove the side wall of the system unit and see that the processor fan is connected to the wires leading to the front panel of the system unit,
Many people, constantly using a computer, cannot always cope with various system errors and understand the notifications that are displayed on the screen. One fine day, the user may be faced with the fact that at the moment of turning on, the computer requires pressing f1 when booting.
If such a message (loading f1) appears constantly, but the computer turns on after pressing, this is not a problem yet. It is worse if, after pressing the indicated key, another message appears on the screen. For those who own English language, there remains a chance to understand what happened. But for those who are only remotely familiar with the language (from the school curriculum), it is not easy to figure out what happened after all.
If you contact the service center, at best, they will send you an employee who, with a rather cunning look, will carry out "some action" lasting up to half an hour and require payment, and at worst, you will be offered to bring a computer on your own. Although the problem is in fact, it can be easily solved without the intervention of third parties.
Let's look at the reasons for the appearance of such an inscription and how to fix the problem. First, let's figure out what exactly the system is trying to "tell" us.
If a window like this appears when the computer boots up
and after pressing F1, the computer boots up further, as if nothing had happened, and the performance is not broken, the interfering confirmation can be turned off as follows:
Press the Del or F2 key at boot time. The following window will appear:
Press F10 and agree, confirming with Enter.
If the message disappears after a reboot, everything is fine. Most likely, the problem was a temporary failure, or a sudden power outage of the computer. And now, let's try to determine the reason, based on what is written on the screen, at startup, if the computer again asks to press f1 at boot time.
CMOS battery has failed
The message has not disappeared, which means that it would be best to open the computer and find a battery like this.
She is responsible for setting the time, date and BIOS settings. If it fails, then the system menu and date settings are constantly confused and the system prompts you to press the F1 key at each boot. In this case, simply replace the battery with a new one.
Also, when removing the old one, leave the computer for 20 minutes without a battery. This will reset any changed BIOS settings, while eliminating another problem that may arise.
As a rule, a message about a dead battery can be displayed and pay attention to it with the phrase "CMOS checksum error".
CPU Fan Error
This message indicates a malfunctioning fan that is cooling the processor. Most likely, it is out of order (and needs to be replaced) or, after a recent repair, the computer was not properly connected. In this case, the system will not allow you to turn on the computer, since overheating and complete failure of the processor may occur during further boot of the system.
This problem is solved by replacing or switching the fan to the required connector on the board.
Keyboard error or no keyboard present
This phrase on the screen means that the PC cannot see the connected keyboard. This happens if the contacts come off the connector or when the keyboard fails. The problem is solved by examining the connectors and the accompanying cleaning of the board from dust or buying a new keyboard.
Do not forget to clear the keyboard auto-off option in the BIOS menu. It works automatically with some input devices.
Another way to remove the constant requirement to press the F1 key is correct setting under the Boot Priority section in the BIOS. As a rule, this error also occurs due to the incorrect sequence of the boot devices.
Is not full list mistakes. We have covered the most common ones. There are many others, such as Overclock (a bug that occurs due to custom CPU speed increase).
The problem can also arise from viruses. In this case, there is nothing left but to clean the disk with an antivirus utility or reinstall it altogether. operating system... By the way, you can reinstall the operating system not only in the standard way, but also in an alternative way - without losing data. You can learn more about how to do this from.

Every computer user will soon encounter such a problem when, when turning on the computer, he asks to press the F1 or F2 key. If you do not press the key, then the system will not boot, but will wait for this key to be pressed. Some users do not pay attention to this and press a key, believing that this is the way it should be. But it really is not normal, the system should boot itself without errors. In this article, you will learn what to do to remove the F1 key press and find out what is the reason for such an error.
Why does the computer start only through F1
There are several reasons why the computer starts only after pressing the F1 key. In general, this appears in order for the computer user to pay attention to the problem and fix it, while the computer may work, but not quite properly, therefore it is possible to continue the boot by pressing F1. If the error was critical, the system would not be able to boot. And to find out why the system does not want to boot itself is quite simple. Above the line Press F1 to continue, the very reason for this is written. Let's take a look at everything possible reasons which asks to press F1.
Cmos checksum bad / CMOS Checksum Error
This is the most common mistake which can meet and ask to press F1. The Cmos checksum bad is that the battery on the motherboard is dead and needs to be replaced. After replacing the battery on the motherboard, the error will disappear. 
Smart status bad backup and replace / Immediately backup your data and replace your hard disk drive
If you see such a recording on the screen of your monitor, then from this phrase you can understand that your hard drive is in poor condition. Therefore, you need to copy all the necessary information from the disc and purchase a new one. The hard drive will stop working soon.
Cpu fan error
Cpu over temperature error what does it mean
If before the message Press F1 to Resume, you see the inscription Cpu over temperature error, then this means that the problem is in the processor temperature. Most likely the processor is overheating, because of this, this error occurs. Therefore, you should check the temperature of the processor and if the problem is overheating, then you should clean the computer or laptop from dust and replace the thermal paste.
Сhassis intruded fatal error system halted how to fix
But the Chassis intruded error when the computer is turned on is corrected by disabling the chassis intrusion check through the BIOS. This error indicates that the case was being opened.
This error occurs when the processor and motherboard are incompatible. Most likely the problem will be solved by updating the BIOS 
Floppy disk fail 40 how to fix
This error appears when the floppy drive is malfunctioning. You can solve the problem by disabling it physically, that is, disconnecting it from the motherboard. But the best way is to disable the floppy disk drive through the BIOS.
