Anonymous users2024-02-05Summary. Hello, glad to answer for you: it could be for the following reasons:
1. Motherboard failure (e.g., load is too high or too low, short circuit in liquid ingress, etc.) 2. Short circuit in the power supply part of the LCD screen or backlight board 3. Power failure 4. Static electricity interference It is recommended that you do the following: 1. Check the power adapter working indicator Check whether the power adapter working indicator is in a normal solid state?
Reminder: Due to the EU green certification standards, some adapters have canceled the design of the working indicator, which is a normal phenomenon. If the indicator light is flashing after being connected to the notebook, it means that the host has a short circuit, and you need to contact the service station for further detection after power-off If the indicator light is normal, but it goes off after pressing the host switch, it is possible that there is a problem with the load of the host.
In the absence of liquid feeding, step 2 can be referred to. 2. Release the residual charge to test and disconnect the host from the 220V mains (note: the laptop needs to remove the battery at the same time), and then press the host switch 3 times in a row, each time for 5 seconds, after the operation is completed, connect the battery separately and reboot the test, and observe whether the fault is eliminated?
3. Contact the service station If the above operations still cannot solve or improve the problem, we recommend that you bring the purchase invoice and host to the nearest Lenovo service station for further testing.
Hello, I am inquiring for you, please wait a while, I will reply to you immediately Hello, I am happy to answer for you: It may be the following reasons: 1. Motherboard failure (such as:
The load is too high or too low, the liquid inlet is short-circuited, etc.)2, the power supply part of the LCD screen or backlight board is short-circuited3, the power supply is faulty4, and the static interference is recommended to do the following: 1. Check the power adapter working indicator Check the power adapter working indicator, is it a normal solid state? Reminder:
Due to the EU green environmental protection certification standard, some adapters have canceled the design of the working indicator, which is a normal phenomenon. If the indicator light is flashing after being connected to the notebook, it means that the host has a short circuit, and you need to contact the service station for further detection after power-off If the indicator light is normal, but it goes off after pressing the host switch, it is possible that there is a problem with the load of the host. In the absence of inlet swimming, step 2 can be referred to.
2. Release the residual charge to test the connection between the host and the 220V mains (Note: the laptop needs to remove the battery at the same time), and then press the host switch 3 times in a row, each time for 5 seconds, after the operation is completed, connect the battery separately and reboot the test. 3. Contact the service station If the above operations still cannot solve or improve the problem, we recommend that you bring the purchase invoice and host to the nearest Lenovo service station for further testing.
I hope the above is helpful to you If you are satisfied with me, please give me a thumbs up

The quality of Asus, Dell, and Lenovo is not bad, but the disadvantage of Asus is that the appearance is not good enough (personal feeling) Dell's performance is slightly worse than Asus, but there is not much difference! Lenovo is an old brand, but on the same level, Lenovo's performance is not as good as that of ASUS and Dell! And some models of Lenovo don't have good hardware heat dissipation! >>>More
1. Poor computer heat dissipation can easily cause the computer to automatically restart, because the CPU has a self-protection function, when the heat threatens the computer hardware, it will shut down and automatically protect itself, if this is the case, it is recommended to let your computer be placed in a dry and cool place, and ensure that it is clean, let the fan run normally, and ensure that the computer has good heat dissipation. >>>More
Take a look at the powerful Y-series, the Y470 is good.

First of all, you have to make it clear what brand you like, and then what series, I personally suggest, now that China has joined the WTO for so many years, some digital products, as long as they are not very high-end, domestic and foreign are almost the same, after all, most of the foreign countries are still made in China, domestic brands such as Lenovo, Acer (Taiwan), Asus (Taiwan), Shenzhou, foreign such as HP, Dell, Samsung, Sony, Toshiba, now 4000 to 5000 price notebooks in addition to Shenzhou and very good configuration, Other brands are similar, and I personally don't recommend buying Samsung, so, Toshiba's, these are Japanese brands, and these brands have about 4000 to 5000 notebooks with similar workmanship to other flat shots, but the configuration is worse than other brands, so unless you want to buy high-end, you don't have to consider these brands. >>>More
It is best for the air conditioner to be higher than 22 degrees, because the temperature difference of 50 degrees Celsius is easy to produce water molecule condensation, if your graphics card is 70 degrees, your room temperature is 20 degrees (air temperature), it is easy to cause water molecules to condense, which is the water mist we usually see on the glass, so it is self-weight. >>>More
