Hardware Testing

RAM

Locate the the RAM+HDD test station, boot into  UBCD, and run memtest86+. Once it says "1" in the "passes" column, with no errors, then it's a successful test.

Hard drive

Locate the the RAM+HDD test station, boot into  DBAN. Depending on the version, one either types autonuke to autodetect fixed disks or selects the fixed disk they wish to wipe from a text-based menu.

You can also find DBAN on the UBCD, but it's not recommended. It's an older version of DBAN, buried a couple of menu levels down -- so it's not worth it to use DBAN on the UBCD unless all the DBAN CDs are lost/defective/eaten.

Power supply

Find the  power supply tester, and attach it to the PSU.

Video card

Locate the the video+sound test station, boot into SLAX, and run the commands:

  • Find out how much memory is in it: grep -i kb /var/log/Xorg.0.log
  • Do a simple benchmark: /usr/X11/libexec/xscreensaver/gflux -fps

Sound card

Locate the the video+sound test station, boot into SLAX, and run the commands:

  • Make sure the sound card is detected: aplay -l
  • Loop some audio: cd /opt/kde/share/sounds; while true; do aplay k3b_success1.wav; done
  • Plug the headphones in and make sure you can hear the audio.

CMOS battery

Find the multimeter (usually located in the storeroom), and confirm the battery is > 3v. If the battery is too low, put it in the cardboard box labeled "Dead CMOS batteries" located near the main bookshelf, so they can be properly recycled.
