Windows XP launched in 2001 with built-in power alarms that warned laptop users when the battery ran low, and the critical-level chime became one of its most remembered sounds. As nostalgia for early 2000s computing grew on YouTube and TikTok, creators began pulling the clip into memes about dying devices, deadline panic and retro tech that refuses to quit. It works because almost everyone who grew up with chunky laptops recognises that gentle warning, the same way people recognise a simple ding sound effect from any old notification.
