This document provides possible solutions to common computer startup issues. Follow the instructions in this document step-by-step to help isolate the problem and find the most appropriate help.

   • If Windows does not start but the screen turns on, continue with the troubleshooting to test the hardware for failures.

   • If there is no noise from the computer case or fans, the lights on the computer do not turn on (including the keyboard lights), and the screen does not receive a video signal, your computer might not be receiving power. Contact HP for further support.
