The Sound of Death

One of my colleagues owns a mobile phone. If the battery of her mobile phone starts to die, then it makes a beep, and after a while it gives another sort of a beep, every so often. The problem is, this sort of beep is the exact same sort of beep that gets made by a computer whose hard disk is about to die a heat death.

She goes into panic mode, searching frantically for a DVD or CD on which to make some backups, can't find one, tries the tech support staff, can't find one of them around, hears another beep, gets even more frantic, rushes off to try and find ... only to hear another of these beeps, coming from her handbag.
