This video outlines troubleshooting steps for no power issues on Dell laptops, including performing a hard reset, checking if the system powers on with or without the AC adapter, and conducting a built-in self-test to diagnose potential hardware issues. It also provides guidance on how to reseat the charger and check the LED indicators for further troubleshooting.
Here are the basic troubleshooting steps for no power issues on your Dell laptop. First, let's hard reset your laptop. If your laptop does not have a removable battery, skip to the next chapter in the video.
If your laptop has a removable battery, turn off the computer and disconnect any. External devices. Unplug the charger and remove the battery. Check your system's manual to know how to properly remove the battery. Press and hold the power button for 15 to 20 seconds to drain any residual power.
Reinsert the battery and reconnect the charger and external peripherals. Check if the issue is resolved. To hard reset a laptop without a removable battery, turn off the computer and disconnect all external peripherals except the charger. Press and hold the power button for 30 seconds until the power LED blinks 3 times. Release the power button and try to turn on the system.
Let's check if the computer powers on without the AC adapter connected. Unplug the charger and attempt to turn on the system. Next, check if the computer powers on with the charger connected, but not the battery. Check your system's manual to know how to properly remove the battery.
Then remove the battery and plug in the charger. Attempt to turn on the system. If the computer did not power on in either of these instances, proceed to the next step. Let's perform a built-in self test. Press and hold the M key and the power button simultaneously. With both buttons pressed, the battery indicator LED will exhibit one of two states.
If the LED lights up amber or white, it indicates a system board failure, and the board needs to be replaced. If there is no LED light, this means the board is functioning properly. If you are unable to complete the test, continue with the next step.
To reseat the charger, disconnect it from the system and the power outlet. Wait one minute and reconnect the parts again. Try connecting the adapter to a different wall outlet if possible. Check if the LED is lit when the charger is connected. If you are still experiencing no power issues, contact us via one of the options on our support website so we can assist you.
