Reanimator9Xa second life for an old computer: a reference guide

How-to

How-to articles

The first article in this section is about the task that starts almost every encounter with an old computer: cleaning. Years of dust block cooling, trap moisture and hide signs of damage. Below is a calm sequence of steps with no solvents, no taking apart dangerous components and no rushing.

A good cleaning shows not in a shiny case but in everything you managed to spot while removing the dust: every suspicious part, every darkened contact.

— Margin note

What to have ready

  • A clear table with good lighting, away from carpets and wool blankets.
  • A soft, dry brush and a couple of stiffer brushes for the heat sinks.
  • A vacuum with a low setting and a narrow nozzle that you will keep from touching any parts.
  • An antistatic wrist strap, or at least the habit of touching grounded metal before you start.
  • A dry, lint-free cloth for the case and a small box for screws.
  • A phone or camera to photograph every stage before you take anything apart.

  1. Unplug everything and wait

    Pull the plug from the outlet and disconnect the monitor, keyboard and every other cable. Let the hardware sit unplugged for a while, especially if it has just come in from the cold: condensation on the boards is more dangerous than dust.

    Hypothetical example: a computer is brought in from an unheated garage in winter, and the owner leaves it in a warm room until the next day before removing the side panel.

  2. Take photos and remove the panel

    Photograph the case from all sides along with the layout of the connectors. Then remove the side panel. Do not open the power supply under any circumstances: it is the metal box with a fan, and its insides are outside the scope of this article.

    Hypothetical example: before disconnecting a ribbon cable, a beginner photographs which way it was plugged in and later reassembles everything without guessing.

  3. Discharge static electricity

    Put on an antistatic wrist strap or touch the unpainted metal of the case. Wear cotton clothing and don't stand on a synthetic rug. Chips from that era are easily damaged by a discharge you won't even feel.

    Hypothetical example: in a dry apartment in winter, the owner moves a synthetic rug out from under the table, works on a wooden floor and touches the metal of the case from time to time.

  4. Remove dust from top to bottom

    Brush dust downward from the upper parts of the board and the heat sinks, holding the vacuum nozzle an inch or so away from the components. Don't blow with your mouth: moisture lands on the board along with the air.

    Hypothetical example: one person holds the vacuum nozzle while another works the brush, so the dust goes straight into the hose instead of rising in a cloud.

  5. Hold the fans still

    Before cleaning a fan, hold its blades with a finger so the brush or airflow doesn't spin it up. A spinning fan can generate current that harms the board, and it can also damage its own bearing.

    Hypothetical example: the fan on the processor heat sink is held in place with a toothpick while the dust is cleared from its blades.

  6. Inspect the connectors and battery

    While the board is clean, take a close look at the sockets, the contacts of the expansion cards and the clock battery. A green or white residue is a sign of corrosion or a leak. Such spots are better shown to an experienced person than scraped on your own.

    Hypothetical example: there is a whitish residue under the battery, and the owner postpones powering on until talking it over with a friend from a vintage computer club.

  7. Wipe the case and reassemble

    Wipe the outside of the case and keyboard with a dry or slightly damp cloth, making sure no drops get inside. Put the panel back on, checking against your photos, and only then reconnect the cables.

    Hypothetical example: the keyboard is turned upside down and gently shaken over a newspaper, then the keys are wiped with a slightly damp cloth.

Common mistakes

  • Opening the power supply or a CRT monitor to "clean it while you're at it."
  • Wiping the board with water, rubbing alcohol or household cleaners without understanding what you are doing.
  • Blowing dust away with your mouth or a strong blast of air, which pushes it deeper and adds moisture.
  • Touching the board while standing on a synthetic rug without first discharging static.
  • Powering on hardware right after bringing it in from freezing temperatures.
  • Throwing the old battery in the trash instead of taking it to a battery drop-off point.

If something doesn't fit

  • If you don't have an antistatic wrist strap, touch the unpainted metal of the case often and work on a wooden surface.
  • If your vacuum is too powerful, make do with a brush and a cloth, collecting the dust a little at a time.
  • If you see leaks or bulging parts on the board, don't try to deal with it yourself; show the device to an experienced person.

Check yourself

  • The hardware is unplugged and has warmed up to room temperature
  • There are photos of the case and connectors from before disassembly
  • The power supply and monitor stayed closed
  • Static was discharged before starting work
  • The fans were held still during cleaning
  • The connectors and battery were inspected in good light
  • No moisture is left inside the case
  • The panel was put back before the cables were reconnected

The information is current as of the date this page was prepared. Old hardware was built in very different ways, so every tip here is general: if a device behaves strangely, stop and ask someone experienced instead of carrying on by guesswork.
