Today’s Eio post is on how to maximize the life of one’s laptop battery.

There are three main ways to maximize the life of your laptop. Let’s call the first method “eliminating to save power;” the second “caring to maintain power;” and the third, “adding to increase power.”

Eliminating to Save Power

The first crucial step in maximizing the battery life of your laptop is to understand what drains the laptop’s power. Once you determine the biggest power drainers, you can focus on saving laptop power by eliminating the biggest power-draining culprits.

The Windows 7 Engineering blogreleased a pie chart which displays where the power in your laptop is allocated to. With an astounding near 50%, the laptop’s LCD screen sucks up the juice. So, the obvious answer with this, is to dim your screen!

Where the power goes in a modern Windows laptop

Friedbeef.com offers some other good elimination tips on saving the battery’s life:

  1. Dim your screen
  2. Cut down on programs running in the background
  3. Cut down on external devices, such as external hard drives, flash drives, WiFi, a mouse

    Don’t let your laptop overheat!

  4. Don’t multitask
  5. Turn off the autosave function in Microsoft word and excel
  6. Lower the graphics use

Caring to Maintain Power

The second method of maximizing your laptop’s battery life is to take proper care of your laptop. When you properly care for your laptop’s battery and power supply, it can enhance how long your laptop will remain powered. There are several ways, again I find help from Friedbeef.com and from Lifehacker.

  1. Defrag regularly
  2. Keep the battery contacts clean
  3. Place computer on hibernate, not standby – hibernate saves your PC where you left off and shuts it down, but standby does not save nearly as much power as hibernate.
  4. Go easy on PC demands – for instance, constant laptop usage over several hours or days is not good for your device. Also, certain uses are more PC intensive, such as watching DVDs, downloading files, or playing video games.
  5. Optimize your hardware for power consumption
  6. Set up and optimize your power options
  7. Avoid laptop overheating

Adding to Increase Power

The final method of maximizing the battery life of one’s laptop is to add on functions or gadgets to increase the amount of power your laptop can support. This method may cost you more money, but the add-ons can be greatly beneficial. Again, Friedbeef is useful.

  1. Add more RAM – This will allow you to process more with the memory your laptop has, rather than relying on virtual memory.  Virtual memory results in hard drive use, and is much less power efficient. Note that adding more RAM will consume more energy, so this is most applicable if you do need to run memory intensive programs which actually require heavy usage of virtual memory.”
  2. Replace your old battery with a new one
  3. Invest in a spare laptop battery
  4. When all else fails, get yourself a more efficient laptop!

In honor of Earth Day, Eio will focus on the “R” of REUSE in the “reduce-reuse-recycle” dictum. Today’s topic is rechargeable batteries, such as our popular 4-pack of Lenmar 2700mAh AA NiMH Rechargeable Batteries.

Rechargeable batteries seem more ecological and economical than single-use batteries, but are they? Here are three useful points to think through when choosing rechargeable versus single-use batteries.

Life-Span

How do rechargeable batteries’ lifespans compare to single-use ones?

While it is difficult to quantify how many hours a battery lasts, most modern-day rechargeable batteries’ lifespans contain around 150 recharges. Single-use batteries, of course, die once they run out. But their lifespans all depends on variables such as the type of battery used and the rate at which a device consumes power.

Costs

Are rechargeable batteries’ longer lifespans worth it despite their high costs?

Rechargeable batteries may be pricier at the outset, but they are thought to save users money over the life of each battery. One downside is that rechargeable batteries and their accompanying chargers can sometimes be more difficult to find. If say, you buy the aforementioned Lenmar battery and battery charger, it is possible you may be unable to replace these items because less-popular products sometimes get discontinued.  Single-use batteries, on the other hand, are available everywhere and come in most sizes.

Waste

How do rechargeable batteries help the environment compared to single-use ones?

Rechargeable batteries do help reduce the amount of waste generated by single-use batteries, which hit 180,000 tons in 2010. However, if one does not recycle rechargeable batteries once they die, contamination is much more likely because they contain heavy metals that some single-use batteries do not possess.

The general rule-of-thumb is to recycle ALL batteries, whether they are rechargeable or not.

Go here for SoCal battery-recycling centers. Go here to mail in your batteries to be properly recycled. Visit Call2Recycle.org for all your recycling needs.

A Final Thought

We would love to give you a definite answer of “rechargeables YES, single-use NO!” But much depends on where you’ll use the battery and how much power the device uses.

Jennifer Berry, over at Earth911.com says this:

So, what are you going to use? Is it a high-tech gadget that needs portable power on a regular basis? Then rechargeables are for you…

[But] rechargeable batteries aren’t necessary for low-cost products that don’t use much power. For example, TV remote controls can sometimes last for years on a single-use battery, so it doesn’t make sense to purchase more expensive rechargeable batteries for such a low maintenance device.”

In sum, when choosing which battery is a better choice, it all depends. Yes, rechargeables may seem cheaper in the long-run, but it all depends on what type of gadget the battery is for.

And in all things, please recycle your batteries correctly. Our future will thank you for that one small gesture.

April 22, 2012 marked the anniversary of Earth Day, a day in which people across the globe promote the restoration and preservation of the earth’s natural environment.

While the day of mobilization and celebration passed, the aims of Earth Day continue in people’s lifestyles. This year, Earth Day campaigns reached a Billion Acts of Green. For instance:

“Yeji from South Korea pledged to not use paper cups anymore, while Pearl from the UK pledged to sell her car and walk everywhere she could.” (read here)

Eio.com shares similar commitments to our earth.

As an electronics company, we comply with the European Union’s Restriction of Hazardous Substances Directive (RoHS). Stocking RoHS compliant parts means we try our best not to sell electronic items containing lead, mercury, or other hazardous substances. We also properly dispose of RoHS exempt items, such as lead batteries. These practices combined, we at Eio contribute to the earth’s reduction of toxic e-waste.

So what can YOU do?

Even if you are not an electronic enthusiast, don’t just throw away your broken or old electronic items. RECYCLE THEM by visiting your local electronics recycling center.

Here are some recycling centers for Eio’s South Bay locals:

Remember, every bit counts. Mother Earth and our future generations will thank you.

Summer is just around the corner here in the North-western hemisphere, so what better time to explore the advantages of solar panels and cells. Even if a solar product never graces your home, knowing the basics of solar energy is still fascinating.

Here is a popular product on Eio, the Velleman SOL5N Solar Charger.

Did You Know (according to Solar Energy 101):

  • Enough energy comes from the sun in one hour to power the global population for a year.
  • Sunlight is a totally renewable resource, unlike oil, coal and natural gas.
  • Solar energy is a great alternative resource due to the decrease in the world’s energy resources and the high pollution caused by many fossil fuels.

The Advantages of Using Solar Energy

Solar energy is harnessed by the photovoltaic effect created in solar cells and panels. Solar panels, a collection of tightly connected solar cells, capture sunlight and convert its energy directly into electricity. And solar panels are more common than you think: although mainly used to adorn rooftops, they also come in handheld calculators, solar powered street and traffic lights, even fans and radios.

According to the Solar Now! campaign in Oregon, the advantages of putting solar panels on your house (or business) include:

  1. Increase in your property’s value
  2. Decrease in your electricity bill
  3. Demonstrates environmental leadership in your community
  4. Lightens your personal impact on the environment

Here’s a memorable (and satirical) picture from The Simpsons, when environmental activist Ed Begley Jr. unveils his solar powered creation to the lovable family. By way of poking fun at “smug” environmentalists, Begley’s humongous solar panels generate enough electricity to make a little fan spin!
