How to fix an HP Elitebook 820 G3 laptop that does not power on

If you have an HP Elitebook 820 G3 laptop that does not power on, you might be wondering what is causing the problem and how to solve it. The power light is constantly green, regardless of whether the laptop is plugged in or not. You can see a photo of the power light [here]. There are no charging lights when you connect the AC adapter. You have tried holding down the power button for one minute several times, but it did not work. The laptop has a non-removable battery, so you are not sure how to reset it. What is the best way to troubleshoot this problem?

There are several possible causes for this issue, such as:

• A faulty AC adapter or power cord
• A dead or discharged battery
• A corrupted BIOS or firmware
• A damaged system board or other hardware component

Possible solutions

Depending on the cause, there are different solutions that you can try to fix the issue. Here are some of the most common ones:

• Check the AC adapter and power cord. Make sure that the AC adapter and power cord are properly connected to the laptop and the power outlet. Try using a different power outlet or a different AC adapter and power cord if possible. If the AC adapter or power cord is damaged, replace it with a compatible one.
• Reset the battery. Even though the laptop has a non-removable battery, you can still reset it by following these steps:

1. Unplug the AC power from the laptop. 2. Press and hold the power button for more than 12 seconds. 3. Release the power button (after at least 12 seconds). 4. The laptop will power on and should boot normally after releasing the power button. 5. Re-connect the AC power to the laptop.

• Update the BIOS or firmware. Sometimes, a corrupted BIOS or firmware can prevent the laptop from powering on. You can try updating the BIOS or firmware using a USB flash drive and following the instructions from the HP support website. Make sure that you download the correct BIOS or firmware version for your laptop model and operating system.
• Contact an authorized repair center. If none of the above solutions work, there might be a problem with the system board or other hardware component. In this case, you should contact an authorized repair center and have them diagnose and fix the issue. You can find the nearest service center using the HP service locator.
