• Plug the AC adapter back into the computer, but do not connect any of the peripheral devices.
• Press the power button to turn on the computer.
• If a startup menu appears, use the arrow keys to select 'Start Windows Normally,' and then press the Enter key.
• After reconnecting each of the peripheral devices, run Windows Update and HP Support Assistant to update all device drivers.

Steps to boot in Safe Mode:

• Restart the computer.
• Press the F8 key repeatedly before Windows starts loading.
