    Recently, whenever I turn on my laptop, there will be a single "beep" as the home screen loads. After that, no further "beeps." Any ideas?

    Reseat your memory. Short single beep usually means no memory installed. Single long beep indicated EFI ROM update in progress, but it would be prior to loading the home screen.
