Hello, this is Emily.
It's possible that the issue is related to hardware issue. Here are a few steps you can take to troubleshoot the issue.
Check the power adapter. Make sure that the power adapter is plugged in properly and that the LED light (if applicable) on the adapter is on. If the LED light is not on, try using a different power outlet.
If the power adapter is working properly, and if the battery is removable, try removing the battery from the laptop and then reinserting it. See if that makes any difference.
Sometimes, a hard reset can help resolve issues with laptops not turning on. To perform a hard reset, unplug the power adapter and remove the battery (if possible). Then, press and hold the power button for 15-20 seconds. After that, reinsert the battery (if you removed it) and plug in the power adapter. Try turning on the laptop again.
If none of these steps work, it's possible that there is a hardware issue with your laptop. In that case, I would recommend contacting HP customer support for further assistance.
