1. The power saving mode appears on the black screen after the computer screen is turned on, indicating that the host has not started. Workaround:
How to troubleshoot the black screen and no display fault when the computer is turned on (the most likely is the motherboard problem, first carefully check whether the motherboard has a bulging capacitor).
Step 1: First of all, check whether the external wiring of the computer is connected, and plug in each cable again to see if the fault is eliminated.
Step 2: If the fault persists, then open the main chassis to check whether there is any excess metal in the chassis, or a short circuit caused by the deformation of the motherboard, and smell whether there is a burning paste in the chassis, whether there are burned chips on the motherboard, and whether the capacitors around the CPU are damaged.
Step 3: If not, then clean the dust off the motherboard and check if the computer is in good condition.
Step 4: If the fault persists, unplug the reset cable on the motherboard and connect it with other switches and indicator lights, and then use the change cone short-circuit switch to see if it can turn on.
Step 5: If you can't turn on the computer, then use the minimum system method, unplug the data cable of the hard disk, floppy drive, and optical drive, and then check whether the computer can be turned on. Then connect the above devices to the computer one by one, when connecting a certain device, the fault will recur, indicating that the fault is caused by this device, and finally focus on checking this device.
Step 6: If the fault persists, the fault may be caused by devices such as memory, graphics card, CPU, motherboard, etc. Then, use the plug-and-unplug method, the swap method and other methods to check the memory, graphics card, CPU and other devices respectively.

Hello,Is yours a desktop or a laptop,Desktop,If there is no host to the display** signal,It will also enter the power-saving mode,This you open the chassis and re-insert the memory to try! In the case of a laptop, it may only be battery-powered, and the battery adapter is not powered, check if the adapter is not working.

It's also very large, preferably half a meter away.

Why does the computer show the power-saving mode as soon as it is turned on, and then the screen goes black, what should I do?
Why does the computer show the power-saving mode as soon as it is turned on, and then the screen goes black, what should I do? Hello, happy to answer your <>
Pro, why does the computer show the power-saving mode as soon as it is turned on, and then the screen is black, the solution is as follows: 1. The connection between the monitor and the host ** line is wrong. Display wiring error is a problem often encountered by users, generally this kind of host has installed a separate graphics card, and many users have inserted the ** line of the display on the motherboard on the display interface, this is the wrong connection method, resulting in the computer can not be turned on normally, the display screen is black and there is no signal input.
The user of the integrated graphics card must be correct when inserting the display interface of the motherboard, in addition, it is not excluded that the **cable is loose, or the display screen is black caused by the **wire damage. 2. The computer memory is not plugged in tightly. Loose computer memory will also cause the problem that the computer cannot boot normally, which is a high chance, so it is recommended to try it first.
We turn on the host computer, open the side panel of the chassis and pull out the memory module, and then reinstall the memory into the memory slot, if not, it is recommended to replace the memory into other memory slots, and then try to boot it to test. If you have friends with multiple memory, you might as well insert one memory first, and the other memory will not be inserted first, try to boot the test, if not, change to another memory insertion, and this memory is not inserted, alternate testing, it is not excluded that one memory is damaged, or one of the memory is loose. 3. Motherboard button battery discharge test.
The button battery is very easy to discharge, there will be a button battery on the motherboard, use a hand buckle or a driver to loosen the tenon of the button battery, then the CMOS battery on the motherboard will automatically pop up, then we can take it out directly by hand, place the button battery for ten seconds, and reinstall it in place, we are testing it on the boot. 4. Look at the indicator light on the keyboard. Insert the keyboard into the computer host, we will turn on the computer host, we try to press the "numlock" key on the top of the small number key on the keyboard, if you press it to go off, and then press it to light up, indicating that the computer host is running normally, generally most of the problems caused by graphics card failure or display ** line damage.
Hope mine can help you <>

Why does the computer screen go black after booting up, and how to solve it.
1. Repair the system: If you can't enter the system normally frequently, press F8 immediately after booting to see if you can enter the safe mode or configure the correct mode for the last time, if so, the system will automatically repair the registry after entering, and recall what operations were done when the first few abnormal phenomena occurred, and according to the suspicion that a certain application software (or driver) caused the problem, uninstall it, and then exit normally, and then restart it should be able to enter normal mode. If you have security software installed, you can use 360 Security Guard plus 360 Antivirus or Kingsoft Antivirus and other similar security software in safe mode to clean up your computer, optimize and accelerate (remove redundant boot auto-start programs, defragment hard disks, etc.) and check and kill Trojans and viruses. >>>More

It is the core driver of the WinNT kernel (including WinXP) operating system volume, which is usually corrupted by installing multiple operating systems, and if the system can still boot, the file can be extracted from the installation disk for recovery, otherwise individual disk partitions may not be usable. If the system does not boot properly, especially if the system partition uses NTFS, I am afraid that the only way to fix it is to reinstall the operating system or use the console. >>>More
