Hi @wilsonconnie374

Welcome to the HP Support Community. 

I understand that your computer is not turning on. Do not worry. I'd like to help. 

Let's try a few steps to isolate the issue. 

Hard reset:

1) Shut down the computer. 

2) Unplug all the Adapters and peripherals connected. 

3) Press and hold down the power button for 15 to 20 seconds. 

4) Plug in the Adapter. 

5) Try to turn on the computer. 
 

1. Check the power supply and battery

If your HP laptop won’t turn on even when plugged in, start by checking the power supply. There are quite a few issues you could have with the power supply.

For example, the problem could be as simple as having the wrong charging cord which means you aren’t getting the proper voltage, or it could be that the power supply has failed [2].

1. To test if the power supply is the issue, completely remove your laptop battery.

2. Then, plug your laptop into a functioning outlet.

3. First, confirm the outlet is functioning properly by plugging another device into it - if it works, the issue isn’t the outlet.

4. If you can power on your laptop without the battery installed, the issue isn’t the power supply, it’s your battery.

5. You’ll need to buy a new one but, in the meantime, you can simply use AC power only.

6. It’s perfectly fine to use your laptop without the battery installed, it just means you’ll always have to be plugged into an outlet to use it.

2. Remove all devices from your laptop

If you have left a memory card, DVD, or USB drive in your notebook, this could be a reason why your laptop doesn’t power on.

It might be getting “stuck” because the BIOS may be trying to boot from a removable storage device. Remove all USB drives and other devices and try to boot up your computer.

3. Check hardware

The last step when diagnosing power issues is to check your hardware. If you’ve recently installed hardware like a new RAM kit, that could be the cause of your boot issues. Remove and reinstall your new hardware and try to boot again.

Unfortunately, sometimes the hardware in your laptop such as your hard drive simply fails and there is no easy fix. If you hear a clicking noise or the drive spinning but then powering down, this is a telltale sign your hard drive has failed [7]. In most cases, this means you’ll need to simply replace your hard drive.

In instances like this, it is smart to have an external hard drive so you can back up any files you may need.

Hope this helps! Keep me posted for further assistance.
