Someone came to me with a laptop that wouldnt boot because of a boot password, i managed to get into the bios by doing a resetting the cmos (holding the power button for 30 seconds with no ac adapter) i got into the bios and disabled the password and then saved the changes exited it rebooted but it comes up with post screen which is a packard bell logo and says f2 for bios and f8 for boot menu. if i press them it will attempt to load but then instantly cut out. i tried the cmos reset and it comes up with a dos screen saying press f2 for bios or f1 to continue the boot. if i press either of these it instantly cuts out. can anyone help me?
