There could be several reasons why your HP laptop is not turning on or charging. I will provide a detailed answer to help you troubleshoot the issue.
1. Check the power source: First, make sure that the power outlet you are using is working properly. Plug in another device to check if it is receiving power. If the outlet is functioning correctly, move on to the next step.
2. Check the power cord: Inspect the power cord for any visible damage or frayed wires. If you notice any issues, it is recommended to replace the power cord with a new one. Also, try using a different power cord to see if it resolves the problem.
3. Check the battery: If your laptop is not turning on even when plugged into a power source, there might be an issue with the battery. Remove the battery from the laptop and then try turning it on while it is connected to the power adapter. If it powers on, then the battery might be faulty and needs to be replaced.
4. Perform a hard reset: Sometimes, a hard reset can resolve power-related issues. To do this, disconnect the power adapter and remove the battery (if removable). Press and hold the power button for around 15-20 seconds. Then, plug in the power adapter (without the battery) and try turning on the laptop. If it turns on, shut it down and reinsert the battery. try turning it on again.
5. Check the motherboard: If none of the above steps work, there might be an issue with the motherboard. This can be a more complex problem and might require professional assistance. Contact HP support or a certified technician to diagnose and repair the issue.
In my personal experience, I had a similar problem with my HP laptop not turning on or charging. After checking the power source and power cord, I realized that the battery was the culprit. I replaced the battery, and my laptop started functioning normally again.
To summarize, the reasons why your HP laptop may not be turning on or charging could be related to the power source, power cord, battery, or even the motherboard. It is important to systematically troubleshoot each component and seek professional help if needed.
