  1. Proper use of the computer

  2. Health concerns • Eye strain • Head, shoulder, neck and back pains • Hand and wrist injuries

  3. Proper workstation design • Well-ventilated room • Use ergonomic computer chairs • Place monitor 16 to 24 inches away, at eye level or slightly at a lower angle; tilt the monitor or adjust the light source; adjust the brightness and contrast settings • Use extendable/retractable legs of the keyboard • Mouse must be easily accessible by your dominant hand • Use document holder to minimize vertical head movement

  4. Good posture • Sit up straight. Feet flat on the floor, use a footrest if needed. • Position your lower arms parallel with the floor and level to your keyboard, with elbows at your side • Keep wrists straight vs. carpal tunnel syndrome • Do not lean on the monitor but stay close enough to the keyboard and the mouse to stay relaxed.

  5. Good working habits • Tap on the keys/mouse button gently • Avoid long, uninterrupted periods of typing • Take short stretch breaks, ideally every 20 minutes to prevent fatigue • Avoid staring at the monitor for long periods • Take vision breaks away: focus on objects at least 20 feet away. • Do eye exercises.

  6. Proper care of the computer • Computer = investment • Hardware, Software, Maintenance, Supplies

  7. Power surges • Use an Automatic Voltage Regulator (AVR) • Unplug your system during lightning storms, even if it is surge protected. • Disconnect from the internet during lightning storms to protect modems • Avoid octopus connections

  8. Basic troubleshooting • Do not panic! • If the computer hangs or is acting weird: • Ctrl + Alt + Delete to bring up the Task List • Shut down the computer and turn it back on after at least 10 seconds • Avoid by not opening too many aps simultaneously

  9. Basic troubleshooting • If a hardware component is not functioning well or not functioning at all: • Examine the power button, power chords, cables and connectors • Try rebooting so that the computer can detect the hardware • Call the lab technician for a replacement hardware component

  10. Basic trouble shooting • Mouse or the keyboard not functioning well: usually due to dust and dirt • Printer not functioning properly: use the printer properties – Maintenance tab. • Scan for viruses • Final resort: contact your vendor in case your unit is still under warranty. • Never try to tinker with the internal hardware unless you have undergone special training on computer maintenance.
