The computer works on but my Lenovo desktop doesn't boot, what's going on? How to solve it? The following is for you to make a detailed introduction to the solution of Lenovo desktop not starting! Hope it helps!
Lenovo desktop won't start solution 1:
There are generally several reasons for the sudden shutdown of the computer:
1. Virus causes.
2. Turn on "Auto shutdown and restart when the computer encounters a serious error".
3. Serious memory errors cause the system to crash (software problems).
4. Malicious program or shutdown
5. Due to the heat dissipation problem of the machine (the CPU fan is not working properly, the overall temperature of the chassis is too high, etc., the CPU fan can be replaced and the chassis cover can be opened to solve the heat dissipation problem of the machine).
6. It may be that the voltage is not very stable, when the voltage is too high or drops below the minimum working voltage of the host power supply, the host will also protect and shut down.
Phenomenon: During the normal operation of the computer, the system suddenly and automatically shuts down or restarts the system.
Phenomenon analysis: Today's motherboards have a temperature monitoring function for the CPU, once the CPU temperature is too high, exceeding the temperature set in the motherboard BIOS, the motherboard will automatically cut off the power supply to protect the related hardware.
On the other hand, power management and virus software in the system can also cause this phenomenon to occur. What to do: If the above sudden shutdown phenomenon keeps happening, first check whether the heat dissipation of the CPU is normal.
Turn on the case to see if the fan blades are working properly, and then enter the BIOS option to see the speed of the fan and the working temperature of the CPU. If you find that it is a fan problem, you will carry out relevant dust removal maintenance on the fan or replace it with a better quality fan.
If the hardware is ruled out, enter the system to thoroughly check and kill the virus. When these factors are eliminated, the cause of the failure may be the aging or damage of the power supply, which can be confirmed by replacing the power supply method, and replace it with a new one if the power supply is broken, and it must not be used continuously, and the hardware will be burned.
Lenovo desktop can't start solution two:
This question of yours is more likely
Does the CPU fan turn after powering on? If it doesn't turn, it's 100% a power supply problem. Focus on checking the quality of the chassis buttons and the power supply itself.
If the CPU is turned on, then consider whether there is a problem with memory contact, clean the motherboard, and then clean and plug the memory again.
Mostly solvable.
If it doesn't work, consider whether there is a problem with the motherboard, check whether the motherboard capacitor has explosion, drum and other phenomena, and if so, it is recommended to send it for repair!
Lenovo desktop Qiqiao cavity can't move Solution 3:
Troubleshooting: The chassis has static electricity, it is recommended to connect the grounding wire, and the recommended method is to eliminate the idea: The short thought is that the motherboard has passed the self-test when it is powered on, but it still can't be turned on normally, and there is an error message in English.
It means that it is a system problem, but you said that it is normal after re-dialing the fiber and inserting the memory, which can only be caused by static electricity in the chassis.
1.The memory contact virtual width imitation is not good.
2.There is a compatibility issue with the miscellaneous memory (e.g., this kind of strange name failure occurs all the time).

There are many reasons why Lenovo desktops won't boot, and the following fault symptoms and solutions are listed:
1. After powering on, the screen does not have any display, and no "dripping" sound is heard from the motherboard speaker.
Solution: Contact the motherboard manufacturer to replace the COMS core digging ruler hail chip or find the BIOS file provided by the motherboard manufacturer to write it with a burner.
2. After pressing the power button, the sail optical drive light flashes, the motherboard power prompt light is on, and the power supply is normal, but the screen is not displayed, and there is no "drip" sound.
Solution: Check whether the CPU is installed correctly, check whether the CPU core is damaged, use the replacement method to check whether the CPU is damaged, and replace the CPU if it is damaged. Sleepy.
3. After pressing the power button, the computer will automatically shut down or have no response.
Solution: Correctly connect the CPU fan to the power connector of the motherboard, and make sure that it is connected to the three-core dedicated CPU fan connector of the CFAN next to the CPU.

Recently, the Lenovo desktop computer used by the author has failed to turn on, and after some investigation, it was found that there may be the following reasons.
First of all, a power failure can be one of the main reasons why it won't turn on. The author checked the power plug and power line and found that there was no looseness or damage. However, in order to further confirm whether the power supply is working properly, the author used a test power supply for testing, and the results showed that the power supply was working normally.
Hence power troubleshooting.
Secondly, hardware failure is also a reason why the computer cannot be turned on. The author checked the hardware inside the computer and found that none of the hardware was loose or damaged. As a result, hardware failures are also eliminated.
Finally, the author considers that it may be an operating system failure that causes the computer to fail to boot. Therefore, the author tried to use the Windows system recovery disk to repair it, but the computer still won't turn on. Subsequently, the author considered that the system may have crashed due to a virus attack, so he carried out an antivirus operation.
However, the computer still won't turn on.
To sum up, the reason why the author's Lenovo desktop computer cannot be turned on may be the operation of Qi Lingyou's system failure or other unknown reasons of Gaohuai. Therefore, the author plans to send the computer to a professional computer repair center for further investigation and repair.

Answer: Hello, the computer can not start and press the power button, check the circuit and the computer power supply if the computer is not powered on, open the computer side panel for inspection when the computer is powered on, disassemble the computer side panel, take off the memory module, and wipe the metal contact point of the memory module with alcohol, which can prevent the computer from not starting due to poor contact of the memory module. If it still can't be turned on, it may be another hardware problem and should be sent for repair in time.
Question: The fan is normal, there is no dripping sound, and the screen is black.
The boot fan is normal, there is no dripping sound, and the screen is black.
Hello question, thanks.
It should be a password on the BIOS, and you need to reset the BIOS settings. And near the motherboard battery, you can see a little jumper device, three pins, two of which are held together by a little plastic clip, and one of the pins is exposed. What you have to do is turn off the computer, unplug the power cord, press the power button a few more times, clear the residual power (the front panel light is not flashing), and then open the case, find the thing I said, it's better to have a pair of tweezers, clamp the little plastic clip, lift it, change it to the other two pins, unplug it after a minute, press it on the original two pins, and then connect the power on, the boot code is gone, ok.
Hello friends:
1) Reason: This is due to the formation of an oxide layer on the surface of the gold finger of the memory or independent graphics card, resulting in poor contact between the memory and the memory slot, and the poor contact between the graphics card and the graphics card slot, resulting in a black screen and inability to boot. >>>More
