Same problem, different method of wording it: HP dv8010 upgrade to Win 7, 64bit, NO sound now. Is it BIOS? Is it embedded? Hwinfo shows ATI/AMD, embedded, without support. Does anyone have a workaround until one could save up for another laptop? This one was >2500 new, one might think it would have support for a few years, no? And I'm scared of BIOS, already bricked ASUS K50IJ updating BIOS after window message: update your BIOS and asked ASUS who gave me instructions. Ha ha. Now the CD seems to come on but the keyboard is not functioning Can I go back and reverse the process?
