What happens when the desktop computer shows that the power saving mode can t be turned on?

Shows poor contact of the data cable;

There is no power supply to the motherboard;

Poor contact of the graphics card;

Poor CPU contact and overheating;

Poor contact of memory modules;

poor power performance;

The machine is infected with the CIH virus and the BIOS is refreshed destructively.

Solution: After the computer is turned on, the energy-saving mode is no signal, and the monitor can not receive the ** signal output by the computer, and the display is only the data cable of the display or the problem of the display itself, as well as the problem of the graphics card. I can hear the boot ** can enter the system, which means that the other hardware of the computer is fine.

It may be a graphics card problem, change your graphics card to another machine and try it, you can be sure; Or if the graphics card on another machine is changed to your computer, you can know whether it is a problem with the graphics card or the motherboard;

If both are available after the test, restore your computer BIOS to factory settings, and if not, take a closer look at the graphics card circuit board to see if there is any burned, explosive capacitors, etc.

Power setting problem: Enter the control panel, find power management, and select the power mode as "always on" There are specific options below, you can cancel the automatic shutdown of the display, if you can't enter the system, enter the BIOS and disable the energy-saving mode.

If the chassis has been turned on normally, it should be that the data cables between the chassis and the monitor are loose, just plug it in and unplug it again.

The desktop has been in power-saving modeSolution 1:

The reason why the battery saving mode (sleep mode) appears is because the user has set the allow sleep mode in Windows, so the system will automatically enter the sleep state when it reaches a certain period of time.

Turn off sleep mode: Open the Control Panel. Select Set Power Options.

Select Change and set sleep time. Set Turn off the display and Put the computer to sleep to never. Save the changes so that your computer will no longer automatically enter battery saver mode.

The power-saving mode means that if the digital all-in-one machine does not operate for a certain period of time, it will automatically shut down, so as to maintain the durability of the battery for a longer time.

The desktop has been in power-saving modeSolution 2:

Press the F8 button to turn on and do not move, the advanced options menu appears in the release hand, select to enter the "VGA mode" to log in to the system. After logging in, right-click on the desktop to select Properties Settings Advanced Adapter List all modes Drag the scroll bar up and down, and click to select "1024*768, True Color (32-bit), 75 Hz, LCD Select 60 Hz", click "OK", click "Apply" OK, and finally restart the computer.

The concept of a desktop is different from that of a notebook, and many notebook features are not available on a desktop. As a result, the power options in a desktop are much simpler than in a laptop. You can turn on the power options from the control panel in the Start menu to adjust the brightness of the display, the time the system automatically goes to sleep, and more, which can also help save electricity.

How to change the schedule settings, open the power management interface, and for laptops, you can see the icon for battery level at the bottom right of the taskbar. Click on this icon, find More Power Options from the menu that opens and click the left mouse button to open it.

The icon for battery level changes depending on how the laptop is powered by electricity: the laptop has a battery installed, but when it is powered by an external power source, the icon appears to indicate that the external power is on, and when the battery is not enough, it will charge and let you know the battery level at this time.

Balanced: This setting will allow you to maximize battery savings while getting the most out of your hardware. For example, when plugging in an external power source, there is no need to worry about battery life, so the system will allow the computer to perform at a higher level.

When using the battery, it should be automatically adjusted to the power-saving mode for how to make the battery last longer, and try not to affect your normal use. These adjustments are automatically controlled by the system and do not need to be done manually.

Energy Saving Program: The most power-saving state, in which the battery lasts the longest at the cost of the computer's performance. Regardless of battery life, get the most out of your computer. Change the power plan settings yourself.

One, it may be that the cable of the monitor connecting to the computer is loose, check it, and second, it may be that the display driver is damaged, so it needs to be reinstalled.

2. If the keyboard light does not light up, it means that it is a memory, CPU, motherboard, or power supply problem.

Solution: 1. If the keyboard light does not light up, first wipe the memory module with an eraser, and check whether the gold finger of the memory module has any burnt marks. Replace the memory in the slot.

2. Check the capacitors and resistors on the motherboard to see if the capacitors are bulging, whether there is a burning smell on the motherboard, and clean up the dust on the motherboard.

3. Remove the CPU fan, power on and turn on, test whether the CPU has a temperature change by hand, if not, the CPU is not working, either the motherboard is broken, or the CPU is not plugged in properly, and the CPU is re-plugged.

4. Power supply problem, although the power supply is powered on, but the motherboard can not work normally, replace the power supply and try it.

5. If the display card is loose or oxidized, the keyboard light will be on, the screen will not be displayed, wipe the gold finger of the graphics card with an eraser, and check whether the capacitance on the graphics card is bulging.

6. Minimize the test method, only leave the power supply, motherboard, CPU, memory, graphics card, keyboard, monitor, unplug all the wires on the rest of the motherboard, use a screw knife to short the switch pins, if normal, add the rest of the hardware, piece by piece, until the cause of the problem is found.

Power-saving mode,It means that the display screen only shows the power-saving mode,And then the black screen standby,This problem is caused by the host has no signal input to the display or the display itself is damaged,The following is an analysis of the reasons and brief solutions。

First, check whether the host is working normally

After turning on the computer, we press the "numlock" key in the key, which is the digital switch switch key on the right side of the desktop keyboard. If the lock light can turn on or off normally after pressing the digital lock key, it can be concluded that the system is operating normally, but it is not ruled out that there is no signal output due to problems with the display hardware.

Note: In addition to pressing the "numlock" key, you can also press the "capslock" case toggle key.

In addition, you can also turn on the speaker and listen for a prompt sound to turn on normally. If the prompt sound is also normal, it can be concluded that there is nothing wrong with the host.

2. The boot failure caused by the monitor itself cannot be displayed

Check whether the power of the display is turned on first, you can observe whether the status indication class on the display is flashing, or you can press the power button of the display to observe whether the screen will light up and show no signal and other prompts, and then turn it off.

If you turn on the power of the monitor, the monitor does not respond, and the status indicator does not change anything, it is likely that the power supply of the monitor is not connected.

If you confirm that the power supply is okay and the monitor is still not lit, it is likely that the power cord of the monitor is damaged, try to replace the power cord of the monitor, if the monitor is still not lit after replacing, it is recommended to send it for repair.

Step 2: Check the VGA cable.

After the power check is done, the screen will usually show a message such as no signal, and then enter standby mode. At this time, you need to check the VGA cable, that is, the signal connection cable between the host and the display, as shown in the figure below.

Note: Computers with discrete graphics cards need to connect the VGA data cable to the discrete graphics card, if it is connected to the integrated graphics card, it will also cause the host computer to have no signal output.

If the discrete graphics card is unplugged and connected to the integrated graphics card, and the machine displays normally, it may be caused by the failure of the discrete graphics card.

3. There is no signal on the display caused by computer hardware

When this happens, it is useless to switch between the upper and lower case keys or the number keys, which means that the motherboard cannot put the signal in and out normally. Then it's obviously a hardware issue.

Poor memory contact.

Poor memory contact is one of the most common causes of no signal output. Unplug the memory module, wipe the gold finger with an eraser, reinstall, observe whether the computer starts normally, the fault is still after reinstallation, it is recommended to replace the memory module and try again.

Capacitor bursting. Check whether the capacitor on the motherboard has a burst of pulp, if there is such a problem, you can try to replace the capacitor and try to boot it again.

If your computer is in battery saver mode and won't turn on, then you can restore this problem by resetting the CMOS settings, you just detain the motherboard's coin cell battery and discharge it for 10 minutes, which can generally solve the problem.

After making sure that the signal cable is firmly connected, try to release the charge on the host: unplug the power cable, press the switch 3 times in a row, each time for more than 3 seconds, and then turn on the test.

If you can't turn on it if you are in power-saving mode all the time, then there should be no power, and you can find a charger to plug it in. In this case, this mode can be removed.

The computer has been in power-saving mode and won't turn on, you can. Turn him off and leave him in a state of no power, and recharging from the new is a power-on state.

The computer has been in power-saving mode, and if it can't be turned on, you need to plug it in and then select the battery again.

The brain has been in power-saving mode, what should I do if I can't turn it on? In this case, well, the computer will be turned off for a while and then see if it can be turned on? Is it that the computer has no brain and is always in power-saving mode, what should I do if it can't be turned on?

In this case, well, the computer will be turned off for a while and then see if it can be turned on? Is it that the computer is out of power, so it will have this effect?

Maybe your computer is malfunctioning, so this mode can't be turned on, it is recommended that you check it to see what causes it.

That means that the power of the computer is not enough, and it must be charged in time to turn on the computer.

What should I do if the computer is in power-saving mode all the time and won't turn it on? I think this computer has been in power-saving mode, and if it can't be turned on, it should be that the motherboard in the computer is broken.
