Thank you for posting on the HP Support Community.
To get the answer to this question, this sounds like hardware related issue with the computer as it's not powering on and it cant be fixed offline.
I would request you to reach out to our Support and our Support Engineers should be able to sort this out. HP Support can be reached by clicking on the following link: www.hp.com/contacthp/
Note: when HP servicing the computer they will attempt to back up your files from your hard drive and this is possible only when the hard drive is not corrupted.
Please feel free to contact us here anytime you need any further assistance. Please click “Accept as Solution” if you feel my post solved your issue, it will help others find the solution.
