Laptop Battery Life

Since laptops now out-sale desktops, I decided to bring this tip out of the archives.

We had a call last weekend, and I get the same question from many laptop users: “Why is the battery life on my laptop so poor?”. The biggest reason is that the battery doesn’t get enough exercise. Most rechargeable batteries today don’t have the memory problem like they did eight and ten years ago. However, unless the battery does get used on occasion, it tends to lose its ability to hold a charge.

Even if you don’t take your laptop outside of the home, I recommend that you run your laptop off of the battery at least twice per month. You don’t have to drain the battery all the way down (some battery experts say not to let it completely deplete ever), but use it until it’s pretty close to empty then plug it back in to recharge. Cycling the charging and depleting of the battery will give your laptop many more productive hours of battery time.

When running from the battery, your laptop will show a little blue battery icon by your clock that shows the approximate batter life remaining. The time shown isn’t 100% accurate, but gives you a quick place to eyeball the remaining time you have on your battery.

Are Macintosh computers poised to make a run?

iPhone 3GJUNE 2008 UPDATE:

I wrote the article below two years ago, ran across it tonight and wanted to write an update to it. At the time I wrote it, I think the now famous Apple and PC guy commercials had just started ramping up and the ominous steps towards Windows Vista were getting closer. My words probably weren’t unique at the time, and I don’t claim to be a sage, but it is astonishing how much the market has really changed since 2006. Linux continues to make a bigger splash world wide, and I continue to install it on more computers here in Western Colorado. Apple’s sales and stock price are literally going through the roof. My Macintosh service calls (mostly for ordering and training…rarely for troubleshooting) continue to escalate as well. Almost 18 months into Windows Vista, I see the machines on only about 10% of my appointment mostly because no one is buying them.

Today, Apple announced their new iPhone version 2.0 will be released in July. Three to four years ago, Microsoft was starting to increase market share of their mobile operating system with their mobile Windows in the smartphone arena. Palm and Blackberry used to dominate that market, but Microsoft was predicted to dominate. Then in June 2007, Apple released the iPhone to extremely positive reviews and cell phone consumers who couldn’t get their hands on one fast enough.

Since then, all other smartphone operating systems have take a hit and iPhone users, largely, couldn’t be happier. I personally have 5-6 clients who are pretty picky phone users and have owned literally dozens of phones over the years, but say they wouldn’t trade their iPhone for anything at the moment. The new iPhone 3G (faster cell speeds) announced today improves on every facet of an already excellent product. The new iPhone 3G will be cheaper, faster, slightly smaller, have a longer battery and talk-time life, offer GPS navigation and incorporate a brand new platform that will allow developers to invent new ways to use this already versatile tool.  

What are your thoughts on my older story below and this new story you just read? Also, what do you think of the new iPhone 3G…hype or substance? Leave me a comment below!!


Story below originally posted on 2006-05-09 16:40:45 -0600

I helped a customer configure a new Macintosh laptop today. This was the third time in a month that I did that. And if I think back over the past year, my Macintosh calls for both help and learning how to buy a new one have escalated by at least double. Is Western Colorado indicative of a bigger national trend?

Maybe so. Macintosh computers are hands down the prettiest machines in the market today. Apple takes great strides to engineer the look and feel of the Mac to make it not only pleasing to the eye, but pleasing to the rest of your house. Certainly a pretty machine does not make the Mac worthy of consideration by itself. However, Apple continues to innovate and deliver solid products to the marketplace. They are easy to adapt to (even for Windows’ faithful), safer to use on the Internet (most likely because of their small market share), and provide ease of use for the most common computer functions; email, Internet, music, pictures and video.

The fact that their prices have steadily decreased doesn’t hurt either. The laptop I helped configure today was their ultra-portable iBook with a 12.1 wide screen with 1 GB of RAM, 100 GB Hard Drive, wireless, CD/DVD Burner and more for under $1400.

Last month, Apple announced that a program (Boot Camp) is available for owners of the new Intel Mac computers that allows them to install and run Windows XP side-by-side with the Mac operating system. Only geeks really raised an eyebrow at this, but the more I think about it, the more I think that some huge changes may be in store in the computer market in the upcoming year to eighteen months.

Zonbu – Part II


In a post last week, I announced that the first Zonbu computer (that I know of) was coming to Grand Junction. It has indeed arrived, and I am enormously impressed with the machine.

Like all Linux computers, the Zonbu requires a high speed wired or wireless connection to operate. Dial-up users need not apply. The reason for requiring a high speed connection is that Zonbu provides automatic backup of files, automatic security updates, and program updates through the Internet connection. The entire setup of this computer (the laptop Zonbu) went like this:

  1. Opened the box -  30 seconds using my USB Drive/pocket knife
  2. Removed laptop from box – 5 seconds
  3. Removed cellophane from laptop and power cord – 1 minute
  4. Powered on the computer and waited for first setup screen – 15 seconds
  5. Answered questions about the name of the user, the time zone, and hooked up to wireless – 90 seconds
  6. Signed into the computer (Zonbu requires a user name and password to for security and warranty reasons) – 10 seconds
  7. Waited for desktop to appear and marveled at the brightness and clarity of the 15.4″ wide screen – 30 seconds (probably less without the ogling)
  8. Clicked the web browser and tested Internet connection – 15 seconds
  9. Oriented the customer on how to use the power meter to know when the battery runs out, how to hook up to wireless at hotels, coffee shops, etc, showed her the word processor, games, and how to turn the computer off – 10 minutes.

Wow!! From box to complete usability in less than 15 minutes, no other laptop on the market can accomplish that in triple that time for any cost much less for under $400! Turns out that Zonbu does not manufacture the laptop, they just put their software and brand on an Everex laptop. Everex is the company that started selling the $199 desktop computer for WalMart and other outlets, and plans to come out with their own laptop for the same stores later this month priced at under $400…again also with a brand of Linux.

After working with the machine for about 45 minutes, I immediately liked the screen, the quietness, the quick, responsive boot-up and applications, and of course the fact that it does not need anti-virus/anti-spyware software and special instructions on what not to do with it. We tested the Zonbu’s DVD playback and it was flawless as well. I did notice that the Zonbu does not appear to ship with two speakers, but don’t quote me on that yet. However, the sound output was quite adequate and clear.

Overall, Zonbu exceeded my expectations for a pre-packaged Linux computer. I stand by my opinion that a Zonbu (or other Linux computer) would be an ideal system for at least 80% of the computing population. And based on this week’s poll, it appears that over 70% of you are willing to look at a non-Windows based computer.

Surge protectors provide false sense of security

The power went out in part of town last night. Before 10am this morning I had already received two calls from people who were having problems as a result.

This seems to happen every time we have a power outage or severe lightning storm. In most cases the computers were on a surge protector when the power went out. I have even seem a few on expensive battery backup systems.

The only way to protect your computer is to unplug it from the wall. No one can predict when the power will go out or spike but lightning is a different story.

A nice surge protector won’t hurt, but it only adds a little more protection.

If you are leaving home for a day or more, unplug your computer just in case. Don’t just turn it off. In many cases that I have seen, the computer has been turned off when the lightning hit and it still caused major problems.

It may be a good idea to check with your computer manufacturer and home insurance to see whether they cover such failures. Many surge protectors carry a guarantee, but cashing in on that guarantee sometimes requires you to jump through some hoops.

You can’t live in fear of a power surge that may never happen, but you should always keep your data backed up. I am constantly reminded that the value of a computer system is not in the parts it is made up of but the data that is stored on it,

Top Ten Questions to ask when Buying “Open Box,” or “Display Models”

By Andy Cochran 

1. Does the item have all of its accessories?

This is a very important question when it comes to things like,
battery chargers or special cables for Ipods, MP3 players, or digital cameras, and remote controls TVs. Ask if everything is there before you buy it. Owners’ manuals and most product software can be found online, if it’s MIA at the store. Have a salesperson print the manual, and give instructions on where to download the required software (if there is any) at home.

2. Is the item in good condition?

  • The condition of a product is sometimes easy to tell, and sometimes
    not. If there is any question of whether or not the item is fully functional, ask for a demonstration; if a demo is not possible, you may still want to purchase it, but if you do, be sure to ask about the seller’s return policy, so you can return it if there’s something wrong.
  • In the case of LCD or Plasma TVs, or other products with screens,
    such as computer monitors or personal media players, make sure and look for defects like dead pixels, or image retention (screen burn-in) if these exist, it is probably better to avoid making the purchase, unless the seller is willing to drop the price significantly, or throw in an extended coverage plan that will cover the item in the event that the condition worsens. If the seller is willing to drop the price low enough to urge you to look past any potential issues, do so with caution.

3. Why is the item being sold?

4. Was the product once a display model, if so, how long did it run for?

  • Even if the item in question was used for awhile, it may not matter
    too much. Many of today’s electronics, like televisions, and other solid-state items, have extremely long expected lives, and even if they are used as displays for a while, they should still be usable for as long as own them. Use good judgment, though. Other items, with moving parts, (like CD players with carousels, or DVD players that have been actively demonstrated) should be purchased using more caution. These things have more wear on them, and sometimes, don’t last as long as new, in the box, products.

5. Was the product returned?

  • If so, why?
    a. Many times things are returned to the store just because the person
    who originally bought it decided to get something else instead. This is especially common among televisions, and MP3 players, or other items that generally have a loose return policy. If the item was returned for this reason, it’s probably safe to buy. People are very picky, and often allow small installation snags, or other small inconveniences to cause them to return electronics. This creates an opportunity for a more patient, or open-minded individual to get a great deal. If the item was returned because it was defective, find out what was done to correct any problems, and if they are really corrected.

6. How many times has the item been bought and returned?
a. If the item has been bought and returned by more than one
individual, there is probably an issue with the item that has not been resolved, or the product is not very user-friendly, or well designed.
It’s probably better not to buy it, unless you have a very good reason to. (such as if you are particularly drawn to complicated, un-user friendly electronics)

7. Is the price right?
a. With "Open Box," or "Display Models," sellers want to get rid of
the product quickly because, the longer it sits on the shelf, the more the price has to drop. Most electronics salespeople have somewhat locked prices on the items they sell, but with "Display Models," this isn’t as much of an issue. Go ahead, make a reasonable offer, or ask, "Is this the best price you can give me?" Most of the time, you will end up with a great deal. You may also want to wait for a clearance on "Display Models" at your local electronics store, because at these times, the products will be at their very lowest prices. At all times, look for a section of the store or a table that highlights the best deals.

8. If the "Display Model" isn’t exactly what I wanted, but is a great
deal, is it worth the compromise?

  • This is a great question to ask yourself, because it’s somewhat
    rare to find exactly what you were looking for being sold as a display model, or on "open box." Sometimes a great product that is similar to, but not exactly what you originally wanted, may be worth purchasing.
    What it all comes down to is this: Is it worth the savings to get something different than what you were originally seeking? For example, if you walked into your local electronics store wanting to purchase an Ipod, but you find an "open box" Zune for a great deal, is it worth it to save a little money? Sometimes it is, and sometimes it isn’t. That decision is up to you.

9. Is the item outdated, or not as good new products that are replacing it?

  • Lots of times, display models are sold when the product reaches the
    end of production. When companies stop making something, they usually allow the stores to sell out of the item, and when this happens, the display model goes on sale. Usually, companies add or remove features from one year to the next, or change model line-ups. If the display model is outdated, you may not want it. It depends on how much you care about having the latest and greatest, and how much better the new models are. Again, is it worth the extra cost? Maybe it is.

10. It’s Christmas season; would I want to give an opened item to a
friend or family member?

  • This question can be answered by again weighing the cost-to-product
    benefit, if the item is truly a great deal that can’t be passed up, buy it, and get a gift receipt, just in case the recipient wants something else. I can say that I have given "Open Box" items as gifts, and haven’t had any angry friends yet. It depends on how picky the potential recipient is, and if they will mind getting something that has been opened. Again, look closely at the item for defects, and cosmetic imperfections. Nobody likes to get something as a gift that is all beat up, but if the condition is good, and you don’t try to hide the fact that it was used, you’ll probably be ok.
  • How would you feel if you received the item in question as a gift?

    By asking yourself these few simple questions, you could very well avoid buying something was somebody else’s headache, and get a really good deal. Don’t automatically decide that something that was a display model, or is "open box" means it’s broken or bad. Always use good judgment, and remember to not let a seemingly good deal blind you to little issues that can become huge problems; one little dead pixel can become many. I have purchased several "open box" items myself, and have had very few complaints; however, I have always held onto my receipt, and considered extended service plans on those items, just in case.

Canon leaps ahead again in DSLR wars

I have made no secret of the fact that when it comes to digital SLRs I prefer Canon over all other brands. I have also backed up my argument with a long list of reasons.

Everytime any other company gets close to Canon, Canon announces a new camera that out paces the competition both in features and price.

Canon did it again this week. They have announced two new digital SLRs, both will make any serious photographer drool unless they are blinded by their loyalty to another brand of camera.

 The most significant of the two announcements is the Canon 40D. The 40D features a 10 megapixel sensor, 6.5 fps, a 3″ LCD view finder, live preview LCD (a rare feature on DSLRs) and nine point focusing. Canon has also targeted the semi-pro photographer by incorporating weather sealed buttons and changeable focusing screens. The camera is also compatible with a new WiFi battery grip that allows wireless transmission of photos even as they are taken.

If it follows the pattern of its predecessors, the 40D will be priced under $2000 with a lens.

The other major announcement was the 1Ds Mark III. This is the new beast camera. In the late 90s Canon knocked Nikon’s F5 out of the top spot with the 1V a weather sealed, drop resistant camera that shot 9 fps. Nikon held the top spot in digital for a couple years until Canon released the 1D, a digital version of the 1V. Try as they might, no one has been able to catch up since.

The 1Ds mark III features a 21 megapixel full frame sensor (most digital sensors are 27mm not a true 35mm), 5fps (if you want faster, go with the 1D Mark III at 10fps), live preview, dust removal, 3″ LCD and dual processors much more dynamic LCD.

Don’t expect this one to be cheap. List price for body only is $8000.

Ubuntu – Day 6

I didn’t use the computer much today, but I need to write a quick blog while I’m working on my Compaq as I sit here and watch my DVR’d “Daily Show” and “Colbert Report” episodes from last week. So, that brings me to tonights word: battery life.

I wrote a quick note a few months ago about the battery life of this laptop with Ubuntu. I can’t confirm it, but I think Ubuntu uses much less battery than a Windows machine. This laptop is at least five years old, and since I didn’t own it when it was running XP and don’t know its battery performance from its Windows, my assessment is purely speculative. However, my experience has been that most laptops only get 1.5 to 2 hours of battery life, especially after a few years. However, my laptop is averaging almost three hours and that’s with a PCMCIA wireless card running and the display running at maximum brightness.

If you use an Ubuntu laptop, let me know your experience with your battery life.

The missing iPhone disclaimer

I am throwing this into the newsletter this week. But I will post it here because I spent too much time writing it.

The Apple iPhone came out this Friday. We have taken the opportunity to write up the disclaimer that should appear on the device, but does not.

The Apple iPhone is operated by touch screen only. There are no hard buttons thus it should not be used while driving. Checking messages and dialing requires constant site of the screen as the buttons are not distinguished by touch. Dialing can only be done by keeping your eyes on the dial-pad. This prevents hitting the wrong buttons. The Apple iPhone display and touchscreen are only visible in low light. Direct sunlight prevent the screen from being viewable until you go in doors. When showing your iPhone to friends and family, make sure to wipe the screen of any face goo before letting them handle or view the device. Do not show the Apple iPhone Internet capabilities to friends or family unless you are operating it under a WiFi signal. The slow AT&T data speeds will not allow observes to be as impressed as they should be with a $500+ phone. Should the battery run down in 18 months, you can send your phone into Apple and it will be replaced within two weeks, any data on the phone should be backed up prior to sending in the phone. When showing off the great features of the iPhone, you must show the following:

1. Voice mail and text messages can be checked in any order.

2. You can drag icons around.

3. You can view YouTube videos (don't try this unless you are operating under WiFi as stated above).

4. Show them a video, some pictures and how it plays iTunes music.

Do not do the following when showing off your iPhone. Do not let any non-iPhone owner type on the onscreen keyboard. Do not mention that the Internet based features are only worth using when you are in a library, outside of an upscale appartment complex or anywhere else that you may happen across an open WiFi broadcast. Do not answer questions about coverage or how well it works as a phone. Do not get into a feature comparison with any Palm Treo owner. Should you be confronted by Treo owner simply insist that the Treo sucks and that the Treo screen is tiny and some models don't even have WiFi. If the Treo owner shows you features that are not available on the iPhone, simply say, "Sheeea! That's stupid who needs that feature? Say this even if the feature really is cool like the easy to feel and press buttons, the ability to view and listen to online video and radio (kinoma player), removable battery, expandable memory, the D-pad, The ability to beam data, the long list of thousands of third party apps, compatability with all 3G networks, the 1.3 megapixel digital camera/camcorder or that it's available on all major cell netorks for under $300.

Congratulations on selecting the new iPhone.

iPhone – cool because it’s marketed that way

I saw an iPhone commercial this weekend. The iPhone is Mac’s newest gadget that is being marketed by people who like to all be different in the same way. I can’t decide which new product is worse, the iPhone or the Palm Foleo. Perhaps they are equally bad for the same reasons.

Both devices are marketed as the next step in portable data evolution. Both devices make this claim as they are left in the dust by devices without the brand name on the outside that do much more.

The Treo was marketed as a phone first and PDA second. The iPaq was a PDA with phone capabilities. The BlackBerry is a email device with phone and PDA functions.

Take the function out of the Treo, the function variety out of the iPaq and the simplicity out of the Blackberry and you have the iPhone.

Samsung once had a pretty nice phone called the i330. It was a Palm/cell phone with a touch screen interface. If this phone had been updated with time, it would be a very strong competitor to the iPhone. However, Samsung dropped the i300/330 line years ago.

Here is a list of pros and cons for the iPhone:

Pros Cons
Plays iTunes music like an iPod Dial pad numbers difficult to see in direct sun light
Pretty icons and interface Only offered by GSM provider AT&T/Cingular
Listen of voice mail in any order No hard buttons for dialing
Pretty screen for videos Not compatible with high speed data/Internet
It makes you cool Only approved third party applications can be added
It’s shiny and white silver Battery time is expected to be less than 10 (5?) hours.
It’s made by Apple Treo <$300, LG Chocolate <$100, RAZR <$100, iPhone $500.

I would have listed more, but I wanted to stop when I ran out of "Pros."

Getting familiar with your digital camera

Although we recently had a class on getting to know your digital camera, many in the group have brand new cameras this time.

Since our meeting this month will focus a lot on the individual cameras that people bring to the meeting most of our notes will be posted after the meeting.

Here are a few items I expect to touch on.

You have a camera, now what?

Once you have the digital camera, you will need a few extras.

  • A 1 gigabyte memory card
  • At least one extra change of batteries
  • A nice padded camera case
  • A memory card reader

Software -

  • Picasa – my personal choice for organizing and backing up pictures (I expect to do a lot of show and tell of this at the meeting this month).
  • Adobe Photoshop Elements – the best consumer program there is for manipulating, editing and fixing pictures.

What about a photo printer?

Personally, I have not used a photo printer for at least three years. Photo printers are too expensive when compared to photo labs and online services such as Shutterfly , Club Photo and Snapfish .

One big reason to use a photo service rather than inkjet or die sublimation printers is proven longevity. Photos processed by photo services are actual photos. While Canon, Epson and HP all claim to produce prints that last as long as actual photos, none of these printers have been around long enough to prove their claims.

Picture Taking Tips

Allow the camera to focus and meter – Don't just press the shutter down quickly. Press the shutter down gently about half way to allow the camera to focus and meter. Squeeze the button down the rest of the way to take the picture.

Save batteries – There are three ways to burn down your batteries quickly:

Over using your zoom lens – the zoom lens is powered by a motor. Too much zooming will drain batteries.

Over using your LCD screen – Many camera makers have done away with the optical view finder (hole that lets you look though the camera) but if your camera has one you should use it. Using the LCD screen runs the batteries down faster than any other feature.

Connecting the camera to the computer – Use a memory reader instead of connecting the camera to the computer. Memory readers use no camera battery and the transfer process goes much faster.

Basic Camera Settings

Digital cameras can be a little overwhelming with all of their little buttons, icons and settings, but there are a few things you should know to help you get started.

Shoot on Auto or Program to start with – Today's cameras to a great job of thinking for you. You don't need to understand exposure, metering or any of those other fancy photo terms to get great shots most of the time.

Set your resolution on its highest settings – Lower resolution means more pictures, but it also means poorer pictures. Get a larger memory card rather than lowering the quality of your photos.

Get to know the custom settings – Once you are familiar with how to take pictures using the AUTO or program settings, your camera likely has custom modes that are designed for specific types of shots such as night, scenery, portraits, and macro. These are usually indicated by little symbols on the camera.
