  • Hi,

    there are so many possibilities, that i can´t point you on "the one" thats solves your problem. Did you have a look into the manual, which i linked? At page 59ff the error codes are listed. These codes are presented by the power led. 

    If you are able to boot into windows, i highly recommend to backup all the relevant data to an external drive. Then i would check for any updates, especially the bios. HP provides a tool for this.

    Best Regards
