Hi tones99,
If the "The power-up solution" you are referring to is the instructions I sent in the private message, and the issue remains unresolved, I suggest calling HP. HP may be able to offer you a discount on a newer model. At this point we have exhausted all I can offer.
The number to call HP is 1-800-474-6836 for Canada and US, or you can Contact HP Worldwide.
Thanks for reaching out to the HP Forums.
