The New Hotness

  • CR2032 Lithium Cell Lifetime

    The Dell Optiplex 9010 acting as a file server woke up dead after I plugged it in after returning from a road trip. Its ID sticker shows a manufacturing date almost exactly nine years ago and the problem was exactly what you might expect:

    Optiplex CR2032
    Optiplex CR2032

    I’d never measured 100 mV on a CR2032 before.

    Because the Optiplex runs headless in the basement, diagnosis required hauling it upstairs, booting it with a display & keyboard, whacking the date into the current decade, then resetting a few other vital bits.

    The electrolytic caps looked to be in fine shape, though.
