When you turn on the laptop immediately starts the BIOS. What if you turn on the laptop or PC opens BIOS? The computer turns on, but the screen of the Monitor "Full Black Tyne"

Hello everyone.

I updated the BIOS on the ASUS laptop I do not remember the model, possibly ASUS X550, through Easy Flash. The update seems to be normal. At least the process ended and the car rebooted. After the reboot, the BIOS opened. Boot devices stopped displayed. In addition, the settings for selecting loading devices were missing, as well as the option "Creating a boot option". Moreover, in SATA configurations, hard drives are displayed, which means it is determined. But in the Boot section there is no, as not and the USB drive, which before it was determined and worked. And he clearly sees the drive, because after the rebuta first begins to turn it, but it does not want to load any device! And just opens the BIOS. That's all.
I understand this update it is updated, because it loads, sees that the new version ... But does not want to ship the devices. Just when turned on opens BIOS. When leaving the reboot. The screws are formatted and it will not be able to boot with them, but he did not open the BIOS before, but simply wrote "Heda your bootable device?", And now neither of the boot drive. Perhaps incorrectly recorded by some data in CMOS, but how to reset this data - I do not have a concept (disassembly not to offer, the car is new).
Updated BIOS with a USB drive connected. The priority of loading was with him.
Chipset - Intel HM76
Bios's firmware took from the official site.
I read the manual of such updates - there everything is simple, stick a flash drive with a new bios, through the Easy Flash utility (which is in the BIOS) select the file and confirm the update.
Mostly shoals with bios a little different kind - black screen.

In general, the solution:

we go to the BOOT in the BOOT section, then turn on Launch CSM

then go to the Security section and turn off the Secure Boot Control parameter.

The situation when the user includes a computer or laptop, and sees that instead of loading the operating system, the BIOS options for setting up the options is not found very often. However, it is impossible and attributed to the category of problems with whom the user has no chance to face. A similar problem is unpleasant to what makes it impossible to use the computer for its intended purpose.

It should be noted that the automatic input to the BIOS when the computer is turned on or the laptop is not provided in all BIOS. In most cases, when any faults are detected, the BIOS stops the download of the computer or laptop. Automatic entrance to the BIOS is called to show the user that he must fix something to the BIOS before continuing to work.

From this it follows that the source of the problem occurs, as a rule, are incorrect BIOS installations. First of all, an overview of the frequency or memory voltage or processor can lead to a spontaneous input to the BIOS or processor - if the user has accelerated the hardware components. In addition, many motherboards react with the BIOS start loading on unexpected power off, perceiving them as evaluating the system instability due to overclocking.

Very often, spontaneous loading of the BIOS when the computer is turned on or the laptop may also testify about the problems with the BIOS itself. In most cases, these problems may be caused by a malfunction of the CMOS batteries. The problem may also appear when changing the composition of the computer or laptop equipment, for example, when installing a new video card.

And finally, you should not discount such a banal cause as a keyboard malfunction or even simply a separate colors. It is possible that the defective keyboard constantly gives a signal that is interpreted by BIOS as a signal from the key intended for the entry in the BIOS.

What needs to be done to correct the problem

If you encountered a situation where the computer automatically loads the computer or laptop BIOS, then, first of all, you should try to restart the computer again. It is possible that you yourself could accidentally press the BIOS input key when rebooting or enabling a computer or laptop. Also, the BIOS configuration program can appear after a reboot of a computer or laptop caused by the unexpected disappearance of the voltage on the network.

However, if you were convinced that the cause of the problem is not in a random error, then other ways to fix it should be applied. First of all, you can try to change the keyboard. Then try to remember whether you did not make any changes in the BIOS. If so, the options you edited should return the initial values. The most reliable will be resetting the BIOS to the default settings. You should also try to extract recently installed boards from the computer if there are such.

If this operation does not help, you can try to change the BIOS battery to the new one. Practice shows that in most cases the battery change helps to solve the problem. However, if the problem still remains, it is likely to conclude that the cause of the situation is the faulty BIOS chip or motherboard.

Conclusion

Causes of the situation when the computer instead of loading the operating system spontaneously loads the BIOS, can be diverse. A similar phenomenon can be caused by both the wrong BIOS settings and a hardware fault. If the situation does not appear by a consequence of a random failure, for example, caused by an external voltage by catch, then in most cases the problem can fix the BIOS reset to the default settings.

Sometimes after some models of laptops cease to load the operating system. Instead, they immediately automatically enter the BIOS when turned on. There, if you view the boot list (), you can pay attention to that it is empty. That is, it does not have a hard disk either DVD drive, nor the boot flash drive, which you could insert into the USB port. Although all of them are connected and can even be displayed in the BIOS among the connected devices.

What to do in this situation and how to return the laptop to the working condition yourself at home?

Why is this happening?

In most cases, this situation occurs, as mentioned above, after resetting the BIOS settings. And it is not necessary to do it through the corresponding menu. It is enough to get a battery in a laptop for a few minutes and turn it off from the electrical network. The update of the BIOS and dust also does not rarely lead to zero.

In some versions of laptops, especially after the 2016 release, there are various options in BIOS, the incorrect installation of which leads to a ban on the boot from the hard disk or flash drive. Therefore, the laptop when turned on itself and enters the BIOS, since it does not see any device from which he could continue to load.

How to fix this situation?

To do this, in the BIOS settings that appear on the screen immediately after turning on the laptop, you need to find the option and disable it, that is, to translate into the Disabled state. It can be called slightly otherwise, for example, Fast Boot and is usually on the Advanced or Boot tab. In ASUS laptops with UEFI system, you need to press F7 in the main window to activate the advanced mode.

Fast Boot option

As soon as you disable fast boot immediately save the settings with the F10 button, after which you restart the laptop and go to the BIOS again.

Next, on the Boot or Security tab (possibly in at the view of the case on other tabs) you need to find the option and also disable it to the Disabled state, and the UEFI and Legacy OS parameter (OS Mode Selection) must be put in value CMS OS or OTHER OS or Legacy.

SECURE BOOT OPTION

Option OS MODE SELECTION

Now save the settings with the same F10 button, reboot and check. The laptop must start booting Windows.

If this did not happen, then try to find the Legacy Support option in the BIOS and put it in the Enabled value. Also, if there is a parameter, it must be used by selecting it with the "ENTER" button and entering the code from the displayed message.

Parameter "Clear All Secure Boot Keys" in BIOS

If nothing helped?

In this case, there is a possibility of having serious challenges with a hard disk. It is necessary and try to replace the worker to another obviously.

BIOS is a basic I / O system, a computer's heart, without which the normal operation of other components and software is impossible. When the computer is turned on, first starts the BIOS and only after turning on it, the operating system is started.

Theoretically, since Windows is loaded after the bios, reinstalling the operating system or add another OS should not affect the normal operation of the BIOS. However, there are often cases when an attempt to establish a second operating system leads to the fact that the BIOS does not load.

In this case, it can be assumed that the BIOS settings have been configured and the default settings can solve the problem. To make a reset of settings, you need to carry out the following operations.

Disable PCs and monitor from the electrical network.
Open the system unit and remove the battery from the motherboard.
Wait a few minutes.
Return the system battery in place.
Connect power to computer and monitor.

After re-launching the BIOS starts loading "as for the first time". If after that the problem disappears, it is recommended to format the boot hard drive and re-install the operating system. It is desirable that that previously worked without problems. It is possible that the added operating system was damaged in the distribution.

Disorders in connections

The likelihood is not loaded that the BIOS is not loaded due to breaks in the supply networks or data loops. To check this option, you first need to listen, whether the cooler is rotated on the motherboard. BIOS is part of the processor and therefore the weak cooling of the motherboard leads to malfunctions.

Perhaps the contact groups of the fan moved away, so it does not work. After that, carefully inspect all cable and loop connections. Check if the dust was accumulated on the motherboard or in contacts. Dust is an excellent electric current conductor, and also creates electrostatic fields to which the electronics is very sensitive.

Clean the apparatus from dust from the help of a vacuum cleaner and brushes.
Sequentially disconnect the contactors and clean the terminals from dirt and oxidation. You can use a school gum for stripping contacts.
Check for the fastening of all connectors. It is likely that the vibrations of contacts were separated, and therefore the equipment stopped working correctly.

After prevention, you can try to re-start the computer. Is the screen black and bios not loaded? Then it can be assumed that one of the internal modules is faulty. Including the motherboard herself could fail or need to reflash it.

You can download a new backup for the motherboard on the manufacturer's official website. Firmware update - the task is complex and pretty risky. Therefore, if you do not know exactly what and how to do - it is better not to risk, otherwise you can also handle the whole computer in place with hard drives. Contact a service center better.

Faulty blocks in the computer

Nothing described above helped? Then the likelihood of iron malfunction increases and you can start checking the blocks.
Disconnect and remove everything from the device not necessarily to start the computer. Leave only the motherboard, the power supply and one of the RAM planks. The computer in such a state will not work, but, check the health of the motherboard itself is possible.
A frequent reason for the impossibility to start the computer to work is the insufficient power of the power supply. For example - you replaced the motherboard on a more perfect that more electricity is required. In this case, the power supply remained old. Or so - in the system unit, additional hard drives were installed or some other functional components. Energy consumption can grow quite strongly. Installing a more powerful power supply will solve the problem. If the question is, of course, in the disadvantage of energy.

Often the BIOS load interferes with a malfunction in the video card. If possible - it is necessary to check the video card with a replacement to another similar. Or set the video card to another computer. Here you need to look at the compatibility of the equipment. Otherwise, you will not find the problem, but you can create new faults.

If in the minimum configuration - the motherboard, the power supply, the operational memory panel - the Socketer earned and the BIOS is loaded, it means that the problem is in one of the removal modules. After installing and connecting the next block, try to turn on the computer again and see what happens. As soon as the BIOS stops start again - it can be assumed that you found a defective block. Now it remains only to find a similar and replace.

In reality, everything turns out to be much more complicated. For example, the computer is sometimes loaded and works quite normally, and then, without a visible reason, it starts to bite. The problem can be both in violations in software and in faults of components.

Such periods of normal operation, alternating with the inability to download BIOS, are characteristic of three types of problems.

The presence of microcracks on the motherboard. Because of this, the contact periodically disappears.
He dried electrolytic capacitors on the motherboard or in the power supply. This malfunction mainly refers to the old, long-term system units. Sometimes faulty capacitors can be revealed according to the characteristic blistering of the case.

Bad contact in the connected wires. As already mentioned - the presence of dust, the oxidation of contacts, insufficiently strong clamps. If there are fixing screws in the contactors - they must be spinning to the end. There is a reverse situation - too highly clamped screws records lead to deformation of the connectors and a contact violation in the compound.

Description

Each time, the BIOS window (blue window with settings) immediately opens when the computer is turned on. After leaving it, it is running the system, or only bios is loaded again.

Very often, this can occur with ASUS, MSI or SAMSUNG manufacturers laptops.

Cause

As a rule, the problem is caused by the fact that the BIOS cannot find the device from which the operating system should be loaded. This can happen for the following reasons:

Setting up the settings of the basic output input system;
There are no media to start the operating system or its malfunction;
BIOS software error;
Computer fault warning - Run the menu signals the presence of incorrect setting, which can lead to the failure of the PC itself. For example, the incorrect frequency of the tire.

It is also possible that the BIOS launch key simply pulled out (as a rule, Del or F2) - because of this there is a permanent basic output input system.

Decision

Solutions are built in the order of simplicity of diagnosis and probability of occurrence.

1. Turn on Launch CSM (BIOS / UEFI mode)

In the case of using systems that do not support UEFI (for example, Windows 7), it is necessary that the "Launch CSM" option is enabled (this option is responsible for compatibility with old operating systems). If it is turned off, first find the "Secure Boot" option - turn it off and restart the computer. Then activate Launch CSM. After you can already try to restart the computer.

We check if there is a Boot Device Control section and the ability to choose between parameters such as: UEFI AND LEGACY, UEFI ONLY, LEGACY ONLY. For old versions of the system, you should choose Legacy and UEFI Only or Legacy Only. For new systems, you need to try different options.

In some versions of the BIOS / UEFI, there is an option to select the type of operating system - there may be options for Windows 8 (7) and Other OS. For a system that do not support the UEFI, select the last option.

2. Check the disk drive

Check the operation of the disc on which the operating system is installed (or bootloader). For this you can:

a) see whether the BIOS disc sees in the section Main..

b) Disable the disk from the computer and insert into the other, checking that it is determined and the data can be read from it.

12. Setting up dates and time

We go to the BIOS and check the correctness of the date and time. If they are incorrect, then set the correct values. Apply the settings and exit from the BIOS.

If, when de-energizing the computer, the date and time is knocked up, the motherboard battery is replaced.

13. Disable fast download

Also can help disabling fast boot to BIOS. To do this, find the option Fast Boot and translate it to position Disabled.. The option itself can be found in one of the sections:

Advanced (optional) - OS Configuration
Bios Features.

* Please note that the "Quick Boot" option is similar to the name, and does not affect our setting, so you do not need to touch this option.

14. Looping loader

Due to the problems of downloading the system, the computer will constantly start the BIOS. The operating system may not be launched due to the problems with the loader.

To solve the problem, run. After on the command line, we perform 2 commands:

bootrec.exe / fixmbr.

bootRec.exe / FixBoot

Check the start of the system. If this did not happen, we perform commands:

bootrec.exe / scanos.

bootRec.exe / RebuildBCD.

* Using the commands of the commands, we scan the disk for the presence of operating systems and write the found systems in the download.

Check the system startup again.

15. Restoration of the system

The problem can be solved using the recovery tool from the control point. Again, run the restore system from the Windows installation disk. After the system roll back.

We try to choose a point at the time when the system started normally.

16. We update the bios

To update the BIOS, download the latest version on the website of the maternal developer. The instruction is attached to the downloaded archive - carefully study and perform step-by-step action.

If the latest version of the BIOS is already installed on the computer, we set it again (reflash the BIOS).
