The computer won’t turn on, but writes power-saving

Power-saving monitor mode at switching on what to do?

To remove the power-saving mode, you need to do the simplest actions. It is necessary to press the menu “Start”, and then choose the item where it is written “Power off”. After that, an additional menu will appear, allowing you to bring the computer out of “Sleep mode”.

To bring your computer or monitor out of hibernation or sleep mode, move your mouse or press any key on your keyboard. If it doesn’t work, press the power button to wake your computer from hibernation mode.

How to disable sleep mode on Windows 7

The hibernation mode is a useful thing if you use it on notebooks, but on personal computers this function is not always appropriate. Why would this mode be inconvenient on a PC, you might wonder? Let’s explain. There are situations when you need to connect to a computer using remote access, and in this mode your efforts will be the system “up to light”. And then, not infrequently, when you want to go to the kitchen for tea, talk on the phone, or just have to be distracted by something, you come, and your “cyber-friend” is sleeping a “dead sleep”. And it doesn’t make much sense to save power on your PC since it doesn’t have any batteries which have a limited charge life span, since it gets its power from the mains. Plus you’ll need to take the time to wake up the “sleeping beauty”. So, the question arises what to do to disable hibernation mode in Windows 7?

So, there are such ways to help disable sleep/hibernation modes :

Windows 7 how to disable sleep mode?

Good question! The control panel will help us. And to do it right, let’s do the following steps:

Disabling hibernation. the control panel to help you

To disable hibernation through the control panel, you need:

hiberfil.sys file. what is it?

hiberfil.sys is a file which is created by the operating system when it goes into hibernation. It is saved in the memory of the hard drive. If you do not need this mode, and there is not enough space on the hard drive to store it, it is reasonable to disable hibernation. And the file hiberfil.Remove sys.

Disabling sleep mode in Windows 7 using command line

Under the Administrator we invoke the command line:

If you need to return the hiberfil file.sys and activate the hibernation mode. then you have to type powercfg.h on.

How to change the HiberFileSizePercent and HibernateEnabled file entries in the registry?

Let’s see how to change entries in the files HiberFileSizePercent and HibernateEnabled and what is it for.

As we found out, it is possible to disable hibernation mode in Windows 7 in several ways. We have already analyzed them above. And now let’s consider how to disable this mode, using the registry. For this purpose, it is necessary to change the records in the above mentioned files.

Find the cause and fix the problem

So, if you think that your case is faulty, follow these steps one by one until you find the node where the problem is. To find the culprit, you will most likely need a set of known good devices, which you will connect instead of the “suspect” ones:

  • Video cable of the same or another type. For example HDMI and VGA. depending on what interfaces your monitor and video have.
  • Graphics card or processor with built-in graphics core (if your system supports it).
  • Another monitor or TV with the right interfaces, another system box or laptop.

Let’s start with an easy one

If the “Power saving mode” message appears when you turn on your computer, unplug it by pressing the button on the power supply unit or the surge protector. Then press the power button on the system unit for 20-30 seconds. This simple trick discharges the capacitors and removes the static charge from the system components. If it was a temporary malfunction, the next start will likely be successful.

However, if this situation occurs regularly, for example, after every shutdown of your PC, it may indicate that your power supply unit is about to fail.

If the monitor doesn’t come out of power saving mode when connected to the system unit for the first time, or after changing the video card (installing a new one or connecting to another one) reset BIOS settings using hardware method and make sure all connections are secure.

If the power saving mode is activated during work or a resource intensive game, it is likely that your video card is overheating. Clean the dust off the PC case, remove the hanging wires and cables, and, if necessary, strengthen the cooling system with the additional fans.

If the signal disappears not immediately, but after starting Windows, boot your computer in safe mode, open the display settings (in Windows 10 they are located in the application “Options”. section “System”. “Display”) and set the minimum resolution. After the subsequent boot in normal mode, which is likely to be successful, change the resolution to a higher one. You can determine its optimal value empirically.

Didn’t help? Go further and find the solution

If simple solutions do not work and do not bring you closer to figuring out which device is to blame for the problem call for help from known good devices.

Start with the video cable. First replace it with a similar one. If signal doesn’t appear connect monitor and graphics card by other type of cable. Replacing with an analogue helped? Faulty cable is to blame. Connecting to other interfaces helped? One or both connectors are faulty. The latter can fail when trying to connect the monitor to the PC with the power on.

Before replacing the video cable, power off the system unit and monitor!

Again it did not work? Now let’s proceed to diagnostics of your video card. First, install it in another slot on the motherboard and check the extra power connection. Though most of videocameras output a picture and without the latter, there are instances for which it is critically important. It did not work? Then one of the two cards is faulty or incompatible with your motherboard.

Incompatibility of boards (on BIOS level) with non-native hardware is encountered in many brand-name PC builds. Wrestling with it is not an easy task: you can try to update the BIOS, hoping that the manufacturer has included support for your device. However, most often the hope proves to be futile.

Also there are “motherboards” that do not want to be friends with certain types of video cards. For example, you recognize only NVidia, only cards without additional power, etc. д. Information on such quirks of your model, most likely, you can find on the network, because it is unlikely you are the first who encountered it.

Instead of a known faulty test card to connect the monitor you can use the processor with integrated graphics (as mentioned above) or another device, such as a laptop.

If the video card you suspect faulty, does not work in one system unit, but works in another, the reason may be not in it, but in the problematic environment. For example, in the RAM (its problems manifest themselves in many ways), in the power supply unit or in the motherboard. To find the culprit, the replacement method is also suitable.

I managed to find a faulty device? It’s up to you to decide what to do with it. The choice is not rich: replace with another, repair or refuse to use. The latter is not the best option, but still.

And yes, serious faults are less common than simple ones. But even if you are unlucky, you have gained invaluable experience and now you will cope with such failures in no time.

What you need to check if “Power saving mode” appears on the screen

Cables are intact, plugs are not “broken

Most often monitor goes in power saving mode because it just isn’t connected to it (or just isn’t inserted into the connector very tightly. try to reconnect it).

Many users, by the way, when rearranging furniture in a hurry just forget to double-check all these points.

Also check the cables for continuity: no twists, kinks, etc.д.

Tip!

If possible, try connecting the monitor to the system unit using a different interface. For example, if you had an HDMI connection, you would need to try using a Display Port.

By the way!

Monitor Connectors (VGA, DVI, HDMI, Display Port). Which cable and adapter you need to connect your monitor to a notebook or PC

Monitor Setting: Receiving (Input)

Most monitors support at least 2-3 interfaces (e.g. in my case it is VGA, HDMI, Display Port).

Because of this “variety” in some cases the following happens: you have connected the monitor to PC via HDMI, but in the monitor settings the signal reception is set to VGA.

Т.е. The monitor waits for a video signal on a completely different interface and not getting it goes into power saving mode.

Monitor settings. Input (receive signal)

The solution in this case is simple: go to the monitor settings (in the Input section) and check if the interface is set correctly (e.g.Auto-mode. not always correctly detects the signal source, so you need to specify this point manually).

The next thing I’d recommend doing is to power off the computer, open the lid of the system box and take out all the RAM cards (see. The screenshot below ).

By the way, it is also a good idea to disconnect all the peripherals from the system unit: printers, scanners, speakers, mice, keyboards, disk drives, front USB panels, etc.д. (leave only the most basic).

Next, clean contacts of storage cards with eraser and brush. At the diagnostic time connect only one strip and try to switch your PC on.

Clean the memory contacts with a rubber band and a brush

If the PC does not turn on. try to put this slate later in another slot and double-check again (the thing is that very often some RAM slot or the slate itself starts to “glitch” and because of this the PC just does not turn on). By the way, especially often such “problems” with RAM slabs occur just after transferring the system unit.

If none of the above helped, try resetting your BIOS/UEFI. It is enough to remove a small battery for a few minutes from the special. of the motherboard slot (see picture). Picture below ).

Checking your graphics card

The last thing I recommend today. check your video card performance. If it is loose in the system unit (approx.: some users do not fix it). then when you move it the contacts could loose, and.

In general try to take it out of the slot and put it back in (if you have another video card it would be better to test PC with it).

By the way, it is possible that you have an integrated graphics card (its presence can be determined by additional cards). The video connectors on the motherboard. board). In this case, try to remove the external graphics card from the slot and connect the monitor to the built in one.

By the way

If your monitor doesn’t show any image at all (but the system unit is working, at least you can hear it making noise). I recommend this post

If all of the above did not yield results. it is very likely that there is some hardware malfunction. In any case, it is hardly possible to give step-by-step recommendations for further diagnostics within the framework of this article.

Analog monitor power saving mode how to disable?

Power-saving modes (and the ability to tune them) were first introduced with Windows 98 and are now present in every operating system.

Using them is associated with the possible need to save battery power (as in laptops, for example), they can be used as an option to shut down (it will take less time to turn on later), as well as to save electricity consumption (imagine how much the company bill can be reduced if it has several hundred PCs).

In this article we will look at how to install, how to choose one of the existing options, and how to remove power saving mode on your computer.

Power saving mode on your monitor and a black screen

Sometimes the computer settings interfere with normal work at the computer or games. If the screen constantly comes up with an inscription that says “power saving mode”, it is unlikely that a gamer will like it. After some time after the end of the activity, the screen becomes black and does not go away until you press any button. How to remove power saving mode when you turn on your computer if you don’t need it?

How to turn off monitor?

In order to remove the power saving mode, you need to do the simplest actions. It is necessary to click on the “Start” menu, and then select the item that says “Shutdown”. After that, an additional menu will appear to bring you out of “Sleep mode”.

If it is only about the computer screen, then in this case, it is necessary to search in the monitor’s menu for power saving. To do this, it will be enough to press the keys of the monitor and enter the menu.

Usually the location of this mode varies depending on the monitor model and manufacturer, but most often the menu is located next to the menu, which is used to adjust the brightness and contrast.

After switching, the computer switches to analog mode, which is convenient.

IMPORTANT! It should be understood that with this option, power consumption will be reduced only to 90% of the standard, but it will be quite enough to reduce electricity costs.

However, if you turn off the vertical scanning, the power consumption will be many times lower. The problem is that it can be not so comfortable to use the screen, so in everything you need to know a measure. Otherwise unpleasant consequences may occur.

The mode which allows switching off 2 scanning units at once is also used. Then the power consumption will be minimal, but it will be much harder to return to normal operation in this mode, because it will take about the same amount of time as turning on the screen from the so-called “cold mode”.

How to turn off the power saving mode on your notebook

Most often users turn off and turn on the power saving mode with the help of “Start” menu. This is the easiest and most reliable way and is available in most cases. You can also go to a menu called “Personalization.

Power saving mode on your monitor: what’s the reason and how to fix it

Endless waiting for something very desirable will drive anyone crazy. For example, a monitor: you are waiting, waiting when it will show the splash screen of Windows, and it stays in nirvana mode Power saving mode and not going to wake up.

What does it mean?? What to do? How to fix it? Yesterday everything was fine. Let me tell you a secret: “Power saving mode” instead of the desktop picture means only one thing.

No video signal

Yes, it means that monitor doesn’t receive video signal and therefore is in power saving mode.

Monitor turns into power-saving mode both in normal mode and in case of malfunction.

  • Your computer is in suspend mode or turned off but the monitor continues to work.
  • The monitor input is connected to the socket of the video card which is currently inactive. For example, PC has two video devices: discrete (separate) graphics card and CPU with graphics core. When you connect discrete video on stationary PC graphics processor, as a rule, is disabled. And if you connect a monitor to its connector (more precisely, to the video output on the back of the motherboard), the latter will not be able to display a picture, because it does not receive the signal.

To fix the situation, just bring your computer out of hibernation mode or, if it is turned off, turn on. Also connect the monitor cable to the working video card.

If it is a malfunction, its causes may be:

  • Damaged, low quality or incompatible video cable and devices.
  • Damage to the video card or monitor connectors.
  • If video cable is connected via adapter adapter (which is highly undesirable as it almost always leads to picture quality degradation), failure of the adapter.
  • Lack of display resolution support by video card.
  • Graphic card overheating.
  • Faulty video card. it is not generating a signal.
  • VGA card slot on your motherboard is not working.
  • Incompatibility between video card and motherboard.
  • Absence of additional video card power supply, if it is foreseen.
  • Faulty RAM, power supply or other system elements (no initialization).
  • Malfunction

In these cases the solution depends on the cause.

Find and fix the problem

So if you think that your case is a failure, follow the steps below one by one until you find the node with the problem. To find the culprit you will most likely need a set of known good devices which you will connect instead of the “suspect” ones:

  • cable of the same or different type. For example HDMI and VGA, depending on what kind of interface your monitor and video have.
  • Card or processor with a built-in graphics core (if your system supports it).
  • Another monitor or TV with the proper interfaces, another system unit or notebook.

Let’s start with a simple

If “Power saving mode” appears during startup, unplug the computer by pressing the button on the power supply or surge protector. Then press the power button on the system unit for 20-30 seconds. This simple trick discharges the capacitors and removes the static charge from the system components. If it was a temporary glitch, the next start up will likely be successful.

However, if this situation occurs regularly, for example, after every PC shutdown, the symptom may indicate an approaching failure of the power supply unit.

If monitor doesn’t come out of power saving mode at first connection to system unit or after changing video card (installing new one or connecting to another one) reset BIOS settings using hardware method, beforehand make sure that all connections.

If the power saving mode is activated during work or a resource-intensive game, it is likely that the video card is overheating. Clean dust off the PC case, remove the hanging wires and cables, and if necessary reinforce the cooling system with additional fans.

If the signal disappears not immediately, but after starting Windows, boot the computer in safe mode, open the display settings (in Windows 10 they are in the application “Options”. section “System”. “Display”) and set the minimum resolution. After the subsequent boot in normal mode, which will most likely succeed, change the resolution to a higher one. It is possible to determine its optimal value empirically.

Didn’t help? Go further and find a solution

If simple solutions do not work and do not get you closer to figuring out which device is to blame for the problem, call for help from known good devices.

Start with the video cable. Replace it with a similar one first. If no signal appears, connect the monitor and the video card with another type of cable. Replacing it with analogous cable helped? Faulty cable is to blame. Plugging into another interface helped? One or both connectors are faulty. The latter can fail when you try to connect monitor to PC with power on.

Before replacing the video cable, the power to the system unit and the monitor must be disconnected!

It didn’t work again? Switch to video card diagnostics. First of all install it to another slot on your motherboard and check the additional power supply. Although most of the vises output a picture without the latter, there are instances for which it is critical. It did not work? Then one of the two cards is faulty or incompatible with the motherboard.

Incompatibility of boards (at BIOS level) with “non-native” equipment is encountered in many brand-name PC assemblies. It is not easy to fight it: you can try to update the BIOS, hoping that the manufacturer has included support for your device in the new version. However, most often the hope proves to be futile.

Also you can meet “moms” that do not want to be “friendly” with certain types of video cards. For example you can set only NVidia, only cards without additional power, etc. д. You can probably find information about such quirks of your model on the net, because you are unlikely the first to encounter them.

Features of the mode

You can disable the power saving mode in a simple way. Through the Start menu select Shutdown, then an additional menu should appear to take you out of Hibernate mode. Display power saving must be turned off in the monitor menu on your computer. When the computer powers on but the monitor does not start, you should check the functionality of the power supply and video card. To determine exactly why the computer behaves in this way, you can with the help of diagnostics. If the screen notifies you to turn on power saving, it means there are reasons for that.

Causes of Power Saving Mode message

Power Saving Mode activation and Power Saving Mode message may appear both in normal and faulty conditions. Both in the first case and in the second one there may be several reasons:

  • Putting the computer into hibernation mode. But the computer keeps working.
  • The monitor’s video input is connected to a video card socket that is inactive. An example of this would be. Two graphic cards are installed on the PC: a discrete card and an embedded video core in the processor. When connected to a discrete graphics card the graphics processor is usually shut down automatically. However, if a failure occurs, the user will see the message Power Saving Mode on a black screen of the monitor.
  • The cable with which the PC is connected to the monitor may be damaged or there may be no contact with the socket. Check the connection quality.
  • Damaged video card and monitor connectors can also signal a lack of video signal. It is also necessary to check the video card slot on the motherboard.
  • If you use an adapter to connect the monitor, then through its malfunction or incompatibility may also appear Power Saving Mode.
  • Incorrect display resolution of your graphics card can cause a lack of video signal.
  • Video card overheating and malfunction.

If you tried to wake your monitor from hibernation mode but it didn’t succeed or the Power Saving Mode message appeared while Windows was booting, then the steps to resolve the issue are.

Why do you need Power Saving Mode?

This has a huge impact on both the environment and the performance of the monitor itself, as well as saving power.

If you ignore the fact that you need to turn on the power saving mode, the screen life will be used up much faster. That’s why many recommend to enable this mode as soon as possible if the monitor is new. As new monitors are quite expensive, in order to save money on repairs or the purchase of a new screen, it is worth thinking about how much money you can save by saving power.

However, the main reason why this type of screen operation is so popular is because of the economy. That is why many buyers do everything possible to make their device work in this mode for as long as possible. No wonder that manufacturers add this type of work to both budget monitors and quite expensive ones. The thing is that in some states, energy tariffs can surprise those who are not used to pay too much for electricity.

In particular, some models of monitors with an energy-saving mode consume several times less power. This is especially important for those who live in Europe, where electricity is quite expensive.

REFERENCE! The so-called “energy saving mode” appeared in the last century. Today it is in every modern monitor.

By the way, if we are talking about laptops, then with its help you can extend the operating mode of the device so much, that it seems as if the laptop was charged several times. over, it saves a lot of time during the switching on of the device, because now it takes only a few minutes.
