Shut down your computer
Before you leave the office please
unplug your laptop (20 Watts)
shut down your computer (73 Watts)
(Unless it is your backup night - continue reading)
- In Watts
- Savings should be greater for older computers and monitors
* Too small to measure with the Kill-a-Watt
Dell Desktop (Optiplex GX620)
73 Logged off/standby
74 On, light use
Dell flat-screen monitor
34 Normal use
Dell laptop (Latitude D610)
20-40 Off, charging
??? Off, fully charged
50-60 On, charging
??? On, fully charged
As you can see, it pays to shut down your desktop computer. Turning it off (with the switch) may cause some wear/hazard. If it will be off long term unplugging will reduce power use to zero and protect it from power surges better than any surge protector.
Monitors are almost completely off when they go on standby. You can save a slight amount of electricity by turning it off. If you will be gone for extended periods turning it off will save some power.
Laptops are generally more energy-efficient than desktops, but they use power any time they are plugged in. The transformer in the plug draws power even when the computer is not attached. We recommend you unplug them when not in use.
BACKING UP COMPUTERS
- Thanks to Mark WEaver from EpiHelp for the following
COMPUTERS are highly efficient machines, but even in a non-active state they draw electrical power when left on. On average, an EpiCH computer uses 12.26 kW/hrs of energy per week when left on (about 86 cents worth of power). Multiply that by 300 or so division computers, and that’s $258 a week!
IN FACT, we could save over $120 a week, just by shutting machines off at night. However…
EPICH COMPUTERS NEED TO BE ON in order to get backed up each week.
So what can be done?
Here’s how YOU can achieve balance between “being seen” by the backup server and “being green” for energy conservation.
1. KNOW YOUR SCHEDULED BACKUP DATE.
Backups are scheduled by location, mostly in the evenings, according to this schedule:
MONDAY: 4TH FLOOR NORTH, MOOS T (PEDS).
TUESDAY: 4TH FLOOR SOUTH, MOOS T (EPICH).
WEDNESDAY: 3RD FLOOR SOUTH, ECRC, NCC
THURSDAY: 3RD FLOOR NORTH, LOWER LEVEL.
FRIDAY: NONE (CATCH UP DAY).
LAPTOPS: M-F 8AM TO 5PM, ALL WEEKEND.
SERVERS: 7 DAYS A WEEK, AT 5PM.
Leave your machine on whichever night you are scheduled.
Ideally, close all applications and log off. Once you have seen a successful backup message the following day(s) you are free to turn off the machine (when your day is done) for the rest of the week!
NOTE: Your machine cannot get backed up if left in a sleep mode, so also consider checking your Power Options control panel (PC) or your Energy Saver Preference (Mac) and set to Minimal Power Management, or Computer Sleep NEVER. This is sometimes confused with the monitor’s sleep mode, which is a separate and perfectly allowable function. In fact, monitor’s can be turned off completely when not in use overnight and backup will remain unaffected.
2. KNOW HOW TO MONITOR YOUR LAST SUCCESSFUL BACKUP.
What if you don’t see the completed backup message, or you get a message that you haven’t been backed up for some time?
You can actually check your last backup date at any time. Just visit the Retrospect (EMC Retrospect, or Dantz Retrospect) application found in Control Panels on a PC, in Applications on a Mac. If the last listed date shown isn’t for the current week, be sure to leave your machine on until it is (even if it’s past your scheduled night). Once backed up, you are again free to shut down the computer (during non-work hours) for the rest of the week!
NOTE: If more than ten days have passed and you still have no recent completed backup message, contact system support. There are likely issues we can (and should) address to ensure timely future backups.
