I understand the computer will not turn on. I will assist you the best I can, but I first require the following information:
1. The computer's model number. If you require assistance locating this information, please reference this website: Locating the Model Number of the Computer
2. The computer's operating system. If you require assistance locating this information, please reference this website to determine your Windows operating system.
3. Have you installed any new hardware on this computer, before the issue appeared?
4. Have you installed any new software or drivers on this computer, before the issue appeared?
Please respond as soon as possible. Thanks for choosing the HP Forums. Have a great day!
