Please allow me to complain in public about HP service and support. My wife has a Compaq Presario notebook, and one day, the wireless radio just "quit". Front light = no radio, Dev Mgr = no BroadCom device, Event Log = "well, it was here, and now seems gone".
I have paid for "overnight service". Learning #1: They just mean shipping. Round trip was almost 3 weeks.
I called TechSupport #1. We had language issues. Mine is English, and his is ... well, not. He refused to set me up with hardware repair unless I first restored my hard drive to factory settings. This was after 4 shots at software / driver updates. Learning #2: Their techs don't want to get machines back.
I called TechSupport #2. Using my learnings, I badgered her into setting up the hardware repair. Learning #3: Be polite, persistent, and don't take "no" for an answer.
Box arrived, shipped it, waited. Got a letter a week later saying the 2 week delivery they expected wasn't going to happen. Why not call in and ask "When?". Learning #4: Don't actually expect a quick answer, to your call, from the Tech, or from HP.
It took them 4 days to get a delivery date, and another day after that to get it correct. Learning #5: They'll tell you a lot to get you off the phone.
Box arrived, opened it, and the radio was dead. But, they did say they replaced the mobo, LCD, and keyboard. Called TechSupport #3. He walked me thru re-seating the radio in the socket on the mobo. Worked as I got off the phone. Learning #6: Don't expect much help from HP.
Wife picked the laptop up off the table, carried it to the sofa, and the radio went dead. I haven't opened it up since, as life has been busy.
Learning #7: Do not buy HP stuff.
Good luck,
