Computer Power Settings Maintenance

Windows Computers

Display Sleep Option: The monitor will power down after the designated time while the
PC tower will stay on.

Navigation: Start Button > Settings > Systems (Display) > Power and Sleep > Screen
Suggestion: Change the screen time to 5 minutes.

Computer Sleep Option: The PC tower will stay on, but it will use low power. Applications will stay open when the PC wakes up.

Navigation: Start Button > Settings > Systems (Display) > Power and Sleep > Sleep
Suggestion: Change the Sleep/Standby time to 20 minutes.

Additional Tips

  • If you will be away from your computer, but need the applications to stay open, you can manually make your computer sleep by going to the Start Button on the taskbar, selecting the Shut Down Button, and clicking the Sleep option.
  • Screen Savers may look fun and interesting while you are working on something other than the computer, but they actually waste energy! You can manually change the computer settings to turn off the Screen Saver. This can be done by going to the Start Button on your taskbar, clicking Settings, selecting Personalization, choosing Lock Screen, and clicking Screen Saver Settings.

Double-sided Printing Settings

Windows Computers

Printing double-sided can reduce the amount of paper used and total office waste. The printing format can be manually changed from doublesided to single-sided on an as-needed basis without altering the default.

Navigation: Start Button > Settings > Devices > Printers & Scanners

Select your primary printer from connected devices, click the Manage button, choose the Printing Preferences option, find where you can manually select printing double-sided, select the doublesided option, click Apply, then click OK.

Changing the settings from printing double-sided to single-sided can be changed without having to change the main printer default. Navigate to the Print screen for your document, change the Printing Preferences from Print on Both Sides to Print One-Sided and select Print.

Additional Tips

  • When you print documents that do not contain sensitive information single-sided, you can re-use them for scratch paper or note-paper to save unnecessary waste of paper.
  • Documents that do not contain sensitive information can be shredded using an office or home shredder and be repurposed as packing materials.

Pre-break Shutdown Checklist

Appliances and office equipment continue to consume energy even when they have been powered down. Unplugging them from wall outlets and turning off power strips can reduce the amount of energy usage over a campus break and can protect electronics from power outages and blackouts.

  1. Turn off all lights in your office space (i.e. desktop lamps, overhead lights, and lighting in common areas).
  2. Shut down all computers, monitors, and laptops.
  3. Turn off all power strips/surge protectors.
  4. Unplug everything that is not plugged into a power strip/surge protector from wall outlets (i.e. coffee makers, computers, printers, fax machines, microwaves, and toaster ovens).
  5. Remove all perishables from office desk areas.
  6. Remove all perishables from office refrigerators and personal minifridges.
  7. Tightly turn off all faucets and report any leaks to Facilities Services at (209) 667-3211.
  8. Water the office plants.

Artificial Lighting Options

The use of LED (Light Emitting Diode) bulbs and CFL (Compact Fluorescent Light) bulbs has increased during the 2000s. CFLs initially replaced incandescent bulbs, but now both incandescent bulbs and CFLs are being replaced by LED bulbs due to their longer lifespans, lower energy usage, and lower overall operating costs.

  LED Bulbs CFL Bulbs Incandescent
Life Span (Hours) 50,000 hours 8,000 hours 1,200 hours
Lumens per Watt 90 45 11
Energy Usage (kWh/Year) 11 kWh/year 26 kWh/year 110 kWh/year
Annual Operating Costs $1.00/year $2.55/year $10.95/year
