The device powers on and then shuts off repeatedly
Device needs a hard reset

Bios is Corrupted
The bios might have become corrupted somehow and you will need to recover your bios. To do this, follow these steps.
Excessively Loud Fan
The laptop fan is very loud or the bottom of the laptop is hot. Fans may spin faster and louder if the computer is excessively hot.
Notebook is not properly ventilated
Keep the laptop on a level surface and give at least six inches of space on all sides of the laptop to allow for air to flow through its vents. If air can’t flow through the notebook it can’t cool itself properly and will cause its fans to spin rapidly.
Dust in the vents
Dust can build up at the vents of the notebook, this will make it hard for it to keep itself cool and cause the fans to spin rapidly. Use a can of compressed air to blow air into the vent on the left side of the notebook to clear it of dust.
The Bios of your Notebook is outdated
A new bios for your notebook may have been distributed to better manage the fan speed and CPU power. To update the bios for your notebook, follow this guide for HP laptops.
Overuse of computer memory
The computer may be overheating due to it running too many processes. To decrease the memory usage of the computer, make sure to close processes when you are done using them and check for background processes that are using a lot of power.
Damaged fan or other component
Check to see if a component of your notebook is damaged. Follow this guide to check for any damaged parts in your notebook.
Device Shuts Down or Freezes Often
Device Freezes often during operation or shuts down shortly after startup
Hardware failure
Use HP’s built in proprietary Hardware Diagnostic tool located in the UEFI menu to detect if there are any hardware issues occurring. Run the Fast Test once, then run the Extensive Test once, and note any hardware failures detected. If the Hardware Diagnostics tool will not load from the boot drive, the software can be downloaded from HP’s site to an external USB drive and ran from there. If the device is unable to boot beyond the UEFI or is unable to run the test at all, consider factory resetting the device or replacing the device
Software failure
To ensure there are no faulty devices connected, disconnect all external devices from the computer, remove any CD’s and close any applications you may have open. Check Task Manager for any applications that are non-responsive and close them. Update any and all out of date device drivers. Update the Bios. Clear and clean any air vents to rule out overheating. Run a virus scan to remove any unwanted viruses and malware. If the problems persist and no solutions worked, take to a certified technician

Battery does not charge properly
The battery does not charge when the laptop is plugged in, or your computer displays the wrong battery percentage.
Faulty battery
Batteries have a finite life and deteriorate over time, resulting in the battery either not holding a charge or not charging at all. If your computer is reading the wrong amount of battery life, it’s possible that your battery is dying and failing to communicate properly with your computer. If you are experiencing either of these symptoms, try running a battery test. Visual step-by-step instructions for how to do this can be found on Hp’s website.
Dirty or broken contacts
Sometimes, if a battery will not charge, it is because the contacts are not clean or are otherwise not making an efficient connection with the laptop. To clean the contacts in both your battery and the laptop, follow these helpful instructions.
Other causes
If the above solutions do not fix the problem, you may simply need a replacement battery.
