Q: Does putting my computer to sleep help extend the battery life? What else can I do to save energy and make my new computer last?
A: We’ve all heard stories about what’s best for a computer’s battery. That’s why I was excited to make friends with Fred Peters, president of Huntington Beach IT Services.
In addition to teaching computing courses in Orange County, Calif., Peters happily makes house calls to revive frazzled computers and the people who rely on them.
Here are his expert tips on how to keep your new laptop running smoothly.
Sleep mode vs. shutting down
Peters notes that your work process will determine whether it’s more efficient to use “Sleep” mode or simply shut down the computer. “It is never fun to have to consistently wait any amount of time if the shut downs are too frequent,” he says. “‘Sleep’ requires more power, but it boots up faster, while ‘Hibernate’ uses less power, but takes longer to come online.” That same logic applies to shutting off your computer completely.
“Your computer will become obsolete before you wear out your computer by turning it on and off a lot,” he adds. “It also doesn’t take more energy to start a computer than to keep it running.”
Sleep mode requires a constant, though reduced use of power (0-6 watts). Peters also notes that colorful screensavers do nothing to conserve energy. Accessing your computer remotely with the Wake on LAN feature also can drain the power.
To get the most for your money, Peters advises adjusting power settings so that it automatically goes into Sleep/Standby mode after about 15 minutes of inactivity, and then shut it down at the end of your day.
Bionic battery life
To get the most out of your computer battery, Peters says to you have to give it a workout. Don’t keep your machine plugged in to an outlet. Instead, discharge the battery daily.
Size does matter
By purchasing a laptop, Peters says that you are ahead in the energy-saving game. Laptops use about 15-60 watts, while desktops use 65-250 watts — plus another 15-80 watts for a monitor.
