I don't know what you have, but my daughter's 2-year-old Compaq Presario 6000 series laptop just got a free repair due to a "service enhancement program," aka recall that they won't tell you about.
I found out about this when I took it for service at a shop near where I work. The woman there told me that she'd not even open it and charge me $40, because she knew what it was. She explained it, and checked something on her computer, confirming it was covered under this program. She also had 2 more of the same model in for repairs.
I had to do some troubleshooting over the phone, letting them know I was aware of the program. Within 24 hours, they agreed to a free repair, even sending me proper packaging and covering all shipping expenses (Federal Express).
The service-enhancement angle might be one to check. Good luck!
