Notebook PC problem? Hi! my friend got a problem with his HP pavilion dv6500 notebook with AMD processor. the DVD drive is not playing or reading any disc as you insert it, and disappear in the list of drives under MY COMPUTER, and when I look at in the device manager its not also listed there. I tried removing the lower and upper filters in the registry but no luck.by the way it is running under windows vista. i tried booting from bootable disc but when I press F9 to get in the menu to select boot drive, DVD drive its not listed there. I try the CMOS/BIOS setting fot BOOT options and DVD drive is selected first, but no luck of getting it work. The drive will eject normally and spin the disc as you insert it but thats all. I tried restoring the system to its factory defaults but no luck at all.I tried to change with another working DVD from another laptop but still the same. Had anyone got this problem before and able to fix it? Thanks in advance.
