@Shay173 It looks like you've done all the relevant steps, however, if the device is not turning on or the light on the power button is blinking, you may want to check with an alternate power cord/adapter, also, check with another wall outlet to check if that helps,

While you respond to that, here's the best way to resolve the issue, using the HP Guided Troubleshooter:

If the above doesn't help or the steps are insufficient, check the below steps:

Let's start with a hard reset of your notebook computer before you try any other troubleshooting steps: click here for steps on non-removable batteries.

Reasons for a hard reset

A hard reset has the following effects:

• Clears the memory.

• Reestablishes the connection between the BIOS and the hardware

The following conditions can be helped by the hard reset:

• Windows stop responding.

• The display suddenly goes blank.

• The computer does not wake from sleep or hibernate modes.

• Software applications freeze or fail to respond.
