Re: Eh..
"They can also be useful in the event of hardware failure as sometimes a motherboard can beep the problem to you[1] - I've fixed a few machines using beep codes for diagnostics."
Most laptops I've worked on in recent years will do a beep code or equivalent power LED flash code, but most desktops nowadays only ever seem to have a single beep code of "failed to complete POST". Most often it's a catastrophic RAM failure. If they even beep at all. Probably because for most users purposes, it doesn't matter what the failure is if POST fails before the video is initialised. It's the same bit you need to replace, ie the whole motherboard. Multiple beep codes indicating failed ports/controllers when most I/O were separate add-on cards made sense.
