After analysis, the problem you described is that the power adapter cannot be detected correctly.The following professional suggestions are given here:
1. Check the grounding of the socket: first, make sure that the socket used at home is properly grounded.If a patch panel is used, check whether the patch panel is also properly grounded.An adapter that is not properly grounded may generate a large amount of static electricity, which may interfere with the identification of the motherboard.
2. Complete charging and discharging: To solve the problem of power supply false detection caused by long time battery unused, you can try to conduct one or two complete charging and discharging operations on the battery.
3. BIOS setting check: If the problem still exists after the above two items are confirmed, it is recommended that you press F2 to enter the BIOS interface and check whether the adapter power displayed after the "AC Adapt" option is accurate.If not, the adapter may be damaged or the power port may be damaged.
I hope the above suggestions can help you solve the problem.For further consultation, please feel free to contact us.thank you!
The Dell machine sometimes encounters it. The above roughly means that the Dell motherboard cannot detect the power adapter.This happens: 1. You use a non Dell original power adapter, 2. Your power plug (plugged into the end of the host) is not firmly plugged, causing a detection error.3. It is estimated that there is a problem with the mainboard detection circuit (very unlikely).It is mainly caused by the power adapter.It is normal to play game cards. When the machine cannot detect the approved power adapter, it will protect the CPU and other components to run at a reduced frequency, just like using the battery alone.
1. Turn off the machine, unplug the power supply, and unplug the battery.
2. Plug in the power supply and start the machine.
3. Shut down the machine and unplug the power supply.
4. Plug in the battery and power supply.At this time, you should see that the battery indicator lights up, indicating that it can be charged normally!
5. Start the machine."Power is connected, charging" will be displayed.
6. Turn off the machine again, and it shows that the battery light is on, which means it is normal.
The success rate is 90%. This happened to me because the power supply was connected several times during use. The ac power adapter water and type cannot be determined
Hello! If the temperature is high, the fan will turn on heat dissipation. If the fan still has no wind at a high temperature, it is recommended that you check whether the cooling channel is blocked by dust or other things, or the fan is damaged.
