HP laptop does not turn on flashes Caps Lock

What to do if the HP laptop does not turn on. HP laptop does not turn on, flashes Caps Lock. What is the malfunction

HP laptop does not turn on, how to start it is the first question that faces the owner of the device. Laptops, due to its mobility, are much more often than table computers, used to work. They are used by students, managers, trade workers, and almost every IT specialist has their own laptop (as Americans call their laptops).

laptop, does, turn, flashes

The mobility of the laptop, its main advantage over desktop PC, has become its problem place, its compactness led to difficulties with cooling during operation, as a result of the percentage of breakdowns of laptops is higher than that of other devices.

Therefore, it is always recommended to buy laptops of well-known brands, such as HP (Hewlett-Packard for example, which have long established themselves in the market and have a dense network of service centers in Russia.

Also, until the end of the expiration of the warranty service, it is not worth neglecting advice, store the packaging from the laptop and the documentation for it, which indicates the guarantee and internal filling of the laptop.

Flashes Caps Lock. How to fix it

It is not necessary to have technical data, however, it is welcome to have initial knowledge about the internal device of the computer, remember that all manipulations you produce at your own risk.

The problem is that over time, contacts leave and the North bridge begins to work incorrectly.

Options to fix the problem

If this did not help, you need to get to the crystal itself and put it on it. In addition to everything, raise the protective cover, fold the foil in several layers with a square and attach the soldering iron on top, so we warm the crystal.

The second option is to close the lid back and plug the ventilation openings of the laptop for 5-10 minutes. Other methods of warming can be found in the public domain. The last measure is to give a finger and not letting go of trying to launch the system.

All these are of course temporary measures and will not replace the full repair of a qualified specialist.

Deciphering Caps Lock flashing on HP laptops

Almost all HP laptops built a special diagnostic utility, which displays a certain sequence of light signals to the Caps Lock key indicator (in some cases Num Lock) if there are problems with the inclusion. According to the combination of blinking (1 flashing, 2 flashing, 5 blinking), you can determine which particular component is faulty and where to begin the elimination of the problem.

A similar role in the system unit of a stationary computer is played by a speaker, which indicates the source of the signal sequences to the source of the problem in the working computer.

To correctly determine the number of flashes of Caps Lock, you need to immediately start to count them when you turn on the laptop.

Simply put, if you turned on the laptop and, starting with the first flashing, counted 3 of them (including the first), after which the casp lock flashes stopped for 3-4 seconds, this means that in your case Caps Lock blinks 3 times, after which, after which, after which, after which The cycle is repeated.

Next, we consider possible combinations and their designation.

Caps Lock on HP flashes 1 time

The central processor malfunction. If your laptop is built on the AMD processor A4/A6/A8/A10, then its failure is very likely. Most often, due to constant overheating and physical wear, these processors stop working, speaking of this by cyclical solitary blinking by the Caps Lock button.

Caps Lock on HP flashes 2 times

Damage to the basic input/output program or in other words. BIOS. It often happens that the memory on which BIOS is recorded is damaged. Because of this, the laptop cannot turn on and Caps Lock begins to blink 2 times in a circle.

Solution. Replacing the flash drive BIOS and its flashing on the programmer.

Caps Lock on HP flashes 3 times

Most often this indicates problems with RAM.

Decision. At home, you can try to get all the RAM modules, clean the contacts on them with a gear (eraser) and try to insert one at a time, each time trying to turn on the laptop.

We extract and change the laptop’s RAM places

Ideally, try to replace the memory module with a deliberately working.

Caps Lock on HP flashes 4 times

Problems with the video chip. If you very rarely cleaned your laptop from dust and did not change thermal grease in it, then you are provided with problems in the video chip (video card). Due to overheating, it degrades and ceases to display the image on the screen. Bottom line. Flashing Caps Lock 4 times and expensive video chip replacement.

Caps Lock on HP flashes 5 times

Problems with a systemic (motherboard). Also a rather sinister symptom. Among the frequent problems with the motherboard, one can note the failure of the northern/southern bridges, video chips, multicortrollers. Repair, as a rule, is also inconsistent.

Caps Lock on HP flashes 6 times

Bios authenticity. Very often his flashing solves the problem and the laptop works further great.

What to do if the HP laptop does not turn on, that is, after starting, only an empty black screen is visible, and on the keyboard the light indicator of the Caps Lock (or Num Lock) indicator flashes on the keyboard?

The problem when turning on the laptop, when nothing happens on the screen, although the fan works is a serious reason for concern. If it is impossible to start a computer, HP usually flashes on the keyboard, the Caps Lock key indicator, and it flashes for a reason. Depending on the frequency of flashing, you can determine the error code that will help us to pre.Diagnose the malfunction.

If the laptop does not turn on, and the battery indicator flashes or does not burn, perhaps the reason is the insufficient battery charge. When working “from the outlet” the laptop should turn on. If you have everything in order with the battery, and when starting, indicators are blinking near the Caps Lock and/or Num Lock keys, you need to count the number of flashes and determine the reason by their number. The official website of the HP gives such a decoding of signals:

Caps Lock/Num Lock Tested component Fault
Flashes 1 time CP The central processor is faulty
Blinks 2 times BIOS Bios damage
Blinks 3 times Memory The memory module is faulty
Blinks 4 times Graphic arts The graphic controller is faulty
It blinks 5 times Motherboard Total system board
Blinks 6 times BIOS BIOS authenticity

But it is not always possible to reliably determine the malfunction in this way, so the laptop will have to be given to the service center in any case. However, we give explanations from the HP website to these faults.

Frequent problem in HP Pavilion DV6. Flashes Caps Lock

A common malfunction in the HP Pavilion DV6 laptopes deserves separate mention. In this series of laptops, the American company openly talked with the cooling system, which is why the devices are very hot during operation. Previously, we have already considered how to make out the Pavilion DV6 and clean it from the dust to reduce the temperature of the system. However, this does not always save.

If the DV6 pavilion does not turn on, and the Caps Lock indicator flashes once, hinting at the processor malfunction, the problem with the high degree of probability can be in the graphic adapter, which also does not bode well and the main thing is to decide where and how to repair the laptop. If the diagnosis “Diagnosis” confirms that the cost of replacing the video chip or the entire system board can be up to half the price of the new computer. However, you will probably be offered a cheaper way of repair. Heating the chip. This method can be called artisanal, but working and relatively cheap. True, no one will give a guarantee for a long.Term performance of a laptop.

When the Hewlett-Packard (HP) laptop is turned on, the power indication lights up, the cooler rotates, the screen remains black, the Caps Lock flashes-the laptop does not turn on.

The inclusion of the Caps Lock/Num Lock key indication in some laptops is a diagnostic function. Indicates the presence of a breakdown of the motherboard (MB), processor (CPU), memory (RAM) or problems in software (BIOS).

Often talks about a serious laptop breakdown.

By indication of Caps Lock, you can approximately determine the breakdown for making decisions for repair and diagnostics.

How to properly conduct an indication of caps Lock (Caps Lock)

In order to correctly conduct the CAPS Lock signal calculation, you must observe the operation of the Caps Lock key indicator to identify a pause between the cycles and the number of light signals in the cycle.

In such a situation, immediately after pressing the power button (Power) there is a sequence of signals with an interval of approximately a second.

For the correct calculation, it is best to turn off the power button (holding 3-4 seconds), then turn on again and count.

What to do if Caps Lock flashes and the laptop does not turn on

If Caps Lock flashes 1 time. CPU error. It is best to check everything from the “removable iron”. T.E. It is best to diagnose all the laptop modules. It is possible that not the central processor failed, but the indication indicates it.

The diagnosis of modules is best done as follows:

  • Alternately, we turn off the module laptop not critical (HDD, SSD, Wi-Fi, DVD, the second bar of RAM);
  • We throw (if available) knowingly workers’ critical modules instead of installed in the laptop (first installed RAM, CPU).

If Caps Lock flashes 2 times. Bios damaged. Diagnostics at home is likely to do not work. You can try to get and sell the contacts RAM-put memory for revenge. But the chances of getting a working laptop after that are very small.

Such a problem is solved by the evaporation of the BIOS chip and the firmware of the new using the programmer.

If Caps Lock flashes 3 times. Memory error. For correction: Get up and place the installed bar of memory or throw a deliberately working new.

Caps lock Blinking # Hp Pavillion G6#

If Caps Lock flashes 4 times. GPU error. Amateur repair is not possible. In the workshop, the engineer watches food and tests the video chip.

The failure of the discrete graphics card of the laptop in this way is not always diagnosed: indication is most often absent at all.

At the same time, the lack of indication cannot be proof of the performance of the laptop chipset.

If Caps Lock flashes 5 times. Motherboard failure. Most often this is a problem with bridges (chipset) of the motherboard. HP brand laptops. The north bridge most often fails. It is not treated at home.

As a diagnostic procedure, a diagnostic heating of the bridge of the motherboard chipset is carried out.

After warming up, as a rule, the laptop begins to start normally. The laptop can work normally after warming up from day to 1-3 months-how lucky.

This happens due to the fact that the chip and contact balls have expanded-the contact improved-the “temporary cure of the patient” occurred.

For repairs with a guarantee of performance, it is necessary to replace the northern bridge of the motherboard using a professional infrared sharestone and special materials (high.Quality flux, solder balls of certain diameter, etc.).

The bridge Rebolling is not as effective as replacing the chip. It is worth remembering when contacting any workshop.

If Caps Lock flashes 6 times. BIOS failure. We fall out the BIOS chip, download the right ROM, sew the programmer. All this is on special equipment.

For accurate diagnosis, you must contact a specialized laptop repair service.

Only in the workshop, after diagnostics, they will be able to tell you why the laptop does not turn on and the Caps Lock indication flashes. Naturally, to carry out subsequent repairs with a guarantee better among professionals.

Some users of laptops from this manufacturer could face a situation where, instead of the usual image when turning on, the Caps Lock key begins to blink on the keyboard. The screen is black and some kind of picture on it is missing.

In this article, we will tell you what this is the most cyclic flashing of the Caps Lock key when turned on on the HP laptop and how, thanks to this, you can determine the source of the malfunction because of which the screen remains black.

The latest questions

Hello masters. Tell me, please, what is the problem if the HP Pavilion laptop does not turn on the Caps Lock flashes and F12 is on fire?

The number of flashes indicates a certain error, the connector or power supply can also be faulty, since the battery does not charge and the laptop cannot start.

Software Service. Computer help. Departure to the house. 12.04.2019 13:06

Try to perform the following actions link.

Try to go to BIOS and reset the Bios mood by default. Also, pay attention to whether the hard drive, RAM are determined. You can also disassemble the laptop and retail the BIOS battery. You should also check the hard drive for errors. It may be required to replace it. Such a malfunction can be due to the breakdown of the motherboard. In a word of reasons there are many, you need to diagnose a breakdown.

HP laptop does not cut, flashes Caps Lock. What is the malfunction?

However, it is not often possible to find a malfunction with this method, because the laptop will have to be given to the service center always. In general, we give explanations from the HP website to the listed faults.

The central microprocessor is faulty. Everything is very simple here, alas, not cheap. HP recommends contacting the service center immediately. BIOS damage. HP recommends that the computer reboots the passage of this error and removes it itself, though this considerable hearing process will like a very long process, therefore it remains to gain patience and just wait. Memory module is faulty. If light indicators say that the inconsistent in the RAM, disassemble the laptop and carefully remove the memory from the slots. Shine it back and try to turn on the computer again. If the situation has remained unchanged, change RAM strings to new ones or contact the specialists. The graphic controller is faulty. HP recommends contacting the service center. The overall failure of the system board is a failure that does not have this shouting mode of the indicator. As well as if the passage is higher, for you the road to the service. The BIOS authenticity failure is a very rare inconsistent associated with unauthorized changes in the characteristics of BIOS in other words of their inconsistency with the hardware platform.

Frequent inconsistency in HP Pavilion DV6. Flashes Caps Lock

The whole mention deserves the all.Focused malfunction in the HP Pavilion DV6 laptopes. In this series of laptops, the South American company frankly rushed with a cooling system, due to which the devices are very warming during operation. Earlier we have already considered how to make out the Pavilion DV6 and clean it from the dust in order to lower the temperature of the accounting system. Still, this not every time helps out.

If the DV6 pavilion does not cut down, and the Caps Lock indicator flashes once, hinting at the malfunction of the microprocessor, the inconsistent with a big bit of probability will like in a graphic adapter, which also does not promise anything good in this matter to be due to where and how to repair a laptop. If the diagnosis “Diagnosis” confirms, the price of the video chip change in another system board can be partially the of the new computer. But, probably for you they will be offered more a cheap repair method. Heating the chip. The myth method has become artisanal, but working and comparable. True, no one will give a guarantee for the long.Term performance of the laptop.

HP laptop errors codes

HP laptops during self-diagnosis can give out light signals that indicate a malfunction of any laptop node.

If your HP laptop flashes Capslock indicator, this may say a lot.

It should be noted that very often the processor itself, but the north bridge of the laptop, which is involved in the process of initializing the central processor, is very often faulty.

The system board failure is a common error that may imply a failure of any laptop node. Detailed diagnosis is required.

Capslock/Numlock (main/auxiliary code)

2.2 (flashes) Caps Lock indicator flashes red 2 times, then white 2 times.

3.2 (flashes) Caps Lock indicator blinks white 3 times, then quickly 2 times.

3.3 (flashes/sound signal) Caps Lock indicator blinks white 3 times (slowly), then 3 times faster.The indicator blinking is accompanied by a sound signal. The blinking of a red indicator is accompanied by a lower sound, and white. A higher sound signal.

3.5 (flashes) Caps Lock indicator blinks white 3 times (slowly), then 3 times faster.

4.2 (flashes/sound signal) Caps Lock indicator flashes white 2 times (slowly), then quickly 2 times.The indicator blinking is accompanied by a sound signal. The blinking of a red indicator is accompanied by a lower sound, and white. A higher sound signal.

4.3 (flashes/sound signal) Caps Lock indicator flashes white 2 times (slowly), then quickly 2 times.The indicator blinking is accompanied by a sound signal. The blinking of a red indicator is accompanied by a lower sound, and white. A higher sound signal.

4.4 (flashes/sound signal) Caps Lock indicator flashes red 2 times, then white 2 times.The indicator blinking is accompanied by a sound signal. The blinking of a red indicator is accompanied by a lower sound, and white. A higher sound signal.

5.3 (flashes) Caps Lock indicator flashes red 5 times, then white 3 times.

5.4 (flashes/sound signal) Caps Lock indicator flashes white 5 times (slowly), then quickly 4 times.The indicator blinking is accompanied by a sound signal. The blinking of a red indicator is accompanied by a lower sound, and white. A higher sound signal.

System board failure is a common error that may imply a failure of any laptop node. Detailed diagnosis is required.

Let the computer cool. If the error is not eliminated after cooling and cleaning the laptop, perhaps the internal components were damaged due to heating.

Display problems

If the laptop stops turning on, the image does not appear on the screen. The problem may be the refusal of the monitor or the transmission circuits of its signal. To check the performance of the system, it is worth pressing the buttons several times equipped with an indication. For example, Caps Lock, Num Lock, Scroll Lock. Which one to choose, to solve the user, depending on the presence of certain indicators of the state.

If when clicking the caps flashes Caps Lock LED, then there is a problem of displaying the image on the screen. This may be related to:

  • A signal transmission of a signal trail;
  • The output of the monitor loop from the motherboard connector due to impact or vibration;
  • Refusal of the Matrix backlight system;
  • Failure of the video adapter;
  • BIOS settings failure.

The easiest way to immediately try to go to BIOS. How exactly this is done, given in the documentation to the laptop. The fact is that individual models Samsung, HP, ASUS, Acer and others require pressing one of the functional buttons. In some series Lenovo, a separate hardware button is designed to enter the BIOS. The same solution is used in Sony VAIO laptops and other series.

After entering BIOS, you should go to the Save and Exit section. Here is selected Load Default Settings. This option may be called Load Defaults and be in another section. Therefore, it is worth seeing in the documentation for the model, where to look for the desired point of reset of settings.

If you go to BIOS, it does not work out by the absence of an image on the screen, it means that the reasons for the malfunctions of the iron, the hardware. First of all, you need to connect an external display device to the laptop. Depending on the set of ports, it can be a monitor or TV. If the image was obtained, video adapters work. It is necessary to check the integrity of the loops, the presence of contact on the motherboard, the performance of the monitor.

Advice! All this work should be entrusted to specialists. Especially if the opening of the case leads to a loss of warranty.

Program way to get rid of the black screen when loading

It happens that a black screen haunts users even when the laptop turns on. But at the start of Windows, it loads for a very long time. Up to 10 minutes of the black screen, and only then. Greeting. Also, a long awakening of the laptop (exit from sleep mode), a long launch on behalf of the administrator can be recorded in the symptoms. What to do?

  • Press the key combination “Windows” R
  • Enter the regedit team into the line. The registry editor will start.
  • Next, we find the Enableulps parameter in all the following sections of the registry and change the value to 0 (zero).

HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class\ HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\amdkmdag HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\amdkmdag HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\\0000

If this parameter does not have this parameter, click CTRLF and enter the Enableulps in the search bar. Try to look like that.

This command we force the video card to work always, never turn off, even if the laptop is not used (just the same sleep mode). But by this, we will slightly raise the power consumption of the laptop and an increase in the temperature of the video card is not critical, but it is worth remembering this.
