I have read about your issue about your HP 15-f009 Notebook and it having startup issues. Try performing a hard reset.
When performing a hard reset please note remove any and all USB devices. Disconnect all non-essential devices.
Here is a detailed troubleshooter for when the computer won't start for Windows.
Plug the power adapter directly into a different wall outlet. Do not plug it into a power strip, surge protector, or secondary power source as this could cause and issue.
Please let me know how this goes.
