By not turning on, do you mean the screen is black and there are no lights indicating whether the power is on, the HDD is being searched?
Do you get a flash screen with the HP logo?
When I diagnose a laptop for refurbishing the first thing I check is whether the flash screen comes on. If it does, I press the key they show to get into the ROM-BIOS and then check the configuration. You may also have diagnostic tools to check memory and the HDD.
If the computer shows lights and it sounds like something is happening, you may have a bad screen, connect an outside monitor and see if that works. Look up how to replace/repair the screen on the Internet.
Another reason for nothing to happen when you turn on, maybe static electricity on the start button. Take out the battery, disconnect the power and press the start button for about 15 seconds. Plug everything on and try to start.
If the memory is bad, computers will not start. Remove the memory, clean and try installing one module at the time trying to start every time. Unfortunately you would have to install good memory to check this diagnostic. Do you have old memory that would operate in this computer?
If the computer boots up but you get a message that media is not connected, you have a failing HDD. You could try reinstalling your operating system. If you can’t, then it is time to get a new one. Get a SSD instead, your computer will fly.
Finally, take out the battery and see if the computer starts. I have had this happens when the battery is bad or is shorting out.
Chances are that one of these things will give you some information why your computer doesn't start.
Good luck.

If wont start begin the basic fix. First you need to check power cord, if the AC transformers box shows signs of discoloration or burning smell it needs to be replace. Check power connectors can become loose over time and stop working. If your laptop is hot to be touch let it cool down before trying to turn it back on. If you do not find any problems with the power supply maybe the internal component cause the issue.
If your laptop won't turn on, there are several steps you can take to try to diagnose and fix the issue:
Check the power source: Make sure that your laptop is properly plugged into a power source, and that the power outlet is working properly. If you are using a power strip or surge protector, try plugging the laptop directly into the wall.
Check the battery: If your laptop has a removable battery, try removing it and reinserting it. Make sure that the battery is properly seated and that the contacts are clean. If your laptop has an internal battery, try holding down the power button for 15-20 seconds to reset the battery.
Check the AC adapter: If your laptop uses an AC adapter, make sure that it is working properly. You can use a multimeter to test the voltage output of the adapter, or try using a different adapter if you have one available.
Try a hard reset: Sometimes a hard reset can fix issues with laptops that won't turn on. To perform a hard reset, disconnect the laptop from its power source, remove the battery (if possible), and hold down the power button for 15-20 seconds. Then, reinsert the battery and try turning the laptop on again.
Check the display: If your laptop appears to be on but the screen is black, it may be an issue with the display. Try connecting an external monitor to see if you can see anything on the screen.
Take it to a professional: If none of the above steps work, you may need to take your laptop to a professional for repair. They can diagnose the issue and provide a solution to get your laptop back up and running

First, ensure the laptop is connected to a power source. Try a different power outlet or adapter. If it still won't turn on, remove the battery (if possible) and hold the power button for 15 seconds. Reinsert the battery or connect the power supply and attempt to turn it on again. If the issue persists, there may be hardware issues, and professional assistance might be needed.
