What's best for my computer: Hibernate, sleep, or shut down?

Unread postby zeru » 02 Apr 2011 10:57

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.

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.
He also adds that you can further conserve energy by using an LCD monitor and ditching the high-end video card unless it’s absolutely necessary. Also, turn off printers and other peripherals when they are not in use.
To kill “vampire power,” TreeHugger.com suggests purchasing a power strip. With all peripherals connected to one source, it’s easy to simply flip the switch on power hogs any time.

Establish a backup process


In addition to Peters’ great advice about conserving energy, I discovered the hard way that it also pays to save backup versions of your work. Invest in an external hard drive to hold your digital music library, special photos, and other key documents. Frequent backups ensure that your data doesn’t die with your laptop.
While you are in the process of backing things up, create an emergency file (on good old-fashioned paper) that contains your computer’s serial number along with other key data such as your credit card numbers and phone numbers to reach each company, along with contact info to your insurance company. Access to that information is vital, particularly in the event of an accident, fire, computer theft, or other catastrophe.
Peters warns that those key pieces of information are not safe on your computer. If you are like me and absolutely need a digital holding space for those nuggets of information, he suggests sites like LastPass as your online vault.

Hi Skywalker, I found this good tip to your question from PCmag.



Extending the Overall Life
The easiest way to give your battery an early death is to damage it. And the two most common causes of damage are from overheating and using an AC adapter with the wrong voltage. For that, make sure to check the voltage of your adapter, especially if using a replacement adapter. Here's how you prevent overheating:

  1. Use a cooling pad when using a notebook computer on your lap.
  2. Avoid propping your laptop on a pillow, blanket, or other soft surface that can heat up or block cooling fans.
  3. Clean your desk. It sounds strange, but if you have a dusty, dirty desk, that dust will get into the vents and clog the cooling fan. Once the dust is inside your laptop, it is much harder to remove. You can try blasting it out with canned air, but you run the risk of damaging internal components. You can also remove the vent and clean out the grit, but remember that taking apart your laptop can void the warranty. So clean your desk at least once a week, if not daily.
  4. Try not to store your laptop in a place where the air temperature exceeds 80 degrees Fahrenheit, such as a hot car or an outdoor patio. And if your laptop heats up or is cold, let it return to room temperature before starting up.
  5. Consider taking your battery out when using your laptop plugged into AC power. Just make sure to keep the contacts clean. If you need to clean them, use rubbing alcohol.
  6. For lithium ion batteries, you do not need to discharge them fully and recharge constantly. Since they don't have the same "memory" as older nickel-metal hydride batteries, it is actually better to discharge a lithium ion only partially before recharging. You need to do a full discharge only about every 30 charges.
