Hello, I'm having troubles with a HP Pavilion dv7-1115eb Entertainment Notebook PC. A friend bought one but the thing was packed with trial software and other crap so I formatted the PC and installed Vista Ultimate. Downloaded some missing drivers from the HP website and got the PC to work, flawless! A few days later she started to have troubles with the multimedia touch panel. That's a touch panel above the keyboard with start, stop, play, pause buttons along with a sound on/off button and the hardware WiFi switch. Sometimes all buttons work perfect but all of a sudden the buttons go bonkers: volume goes up, then down, network switches on and off... HP says it's a software problem and wants to charge here €50.00 for installing the recovery software. (I did not create recovery DVD's before I formatted the thing). Personally I think it's a hardware problem, but the guy @ Mediamarkt said it was software for sure. He also advised to install an OEM Vista?!? Someone here who can give me some advise? Thanks!
