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.
Things we don't test yet
Things we need to develop a test procedure for:
- Network cards
- Motherboard (see Portland's Advanced Testing Kit)
- CPU (see Portland's Advanced Testing Kit)
