Acer Aspire One #1 Netbook

Our current favorite small netbook, the Acer Aspire One, is now the #1 selling netbook according to 3Q sales numbers as reported by DisplaySearch.

We expect competition to become only more fierce with companies continuing to flood the market with new models. Over the past week we just saw major price reductions from Lenovo whose IdeaPad S10 is now going for $349. HP similarly cut prices.

At some point, there could also be a response to the netbook market from Apple, either in a smaller screen laptop, a lower cost MacBook Air, or a tablet (a large iPod Touch?). While Apple has historically stayed away from cheaper products, this is the fastest growing part of the computer market.

Despite Acer’s loads of new netbook models released over 2008 (such as the recent Eee PC 1002HA), Asus gained market share with its simpler lineup with the Aspire One. See the full results below.

Computer Recycling in the D.C. Area

While we are shopping for the holidays, we should remember to recycle our old electronics. This article covers recycling information and locations for the Virginia, D.C., and Maryland area.

Dangers of Computer Waste

Old computers and monitors have harmful materials that can seep into the ground water and air if thrown in your normal trash. The cadmium and mercury in displays can damage the nervous system. Computers also may contain lead (causing birth defects and learning disabilities) and CFCs (destroying the ozone layer).

Donations

If you have a working computer, you can get rid of it through:

  1. Craigslist (Washington D.C. metro area) has sections for selling or giving away free stuff.
  2. Freecycle is a free program to give people items for reuse. They have groups everywhere, including, Washington D.C., Virginia, and Maryland.
  3. D.C. Goodwill accepts computers that are not more than 5 years old. They will not take CRT monitors, the older large monitors that have been replaced by LCDs.

Recycling Computers and eWaste

The easiest way to recycle an old computer is to do it with the purchase of a new computer. Apple, Dell, HP, Sony, Toshiba and others have a corporate recycling program that allows you to give them your old computer after buying your new computer.

This image shows the Free Recycling Kit option that Dell provides in their services customization when you buy a new computer.

Drop-off Locations for Computers and other eWaste

The EPA eCycling site is the closest thing to a definitive set of inks to eCycling programs across the country. Below are the best links I found to the D.C. area programs:

Washington D.C.

DC Free Electronic Disposal Sites:
DPW (Department of Public Works) offers free, weekly Household Hazardous Waste (HHW) and electronic recycling (e-cycling) drop-off service at the Benning Road Trash Transfer Station, 3200 Benning Road, NE, and at the Ft. Totten Trash Transfer Station, 4900 Bates Road, NE, each Saturday from 8 am to 3 pm.

Virginia

Arlington, VA HAZMAT Program:
Arlington residential households can recycle computers and other electronic items at the County’s HHM drop off sites.

Maryland

Maryland Department of Environment Electronic Recycling Collection Events and Locations:
Montgomery Country Shady Grove Transfer Station and Recycling Center

Ink Cartridges

Ink cartridges can be dropped off at Micro Center in Fairfax, Virginia. Office supply stores such as Staples, Office Max, and Office Depot take used toner cartridges and sometimes even give you credit toward a store purchase for dropping them off.

Cell Phones

Cell phones can be dropped off at cell phone stores. Working phones can also be donated to women’s shelters. Unactivated phones still have the ability to call 911 so they can be useful.

Recycling Can Be Easy

With many recycling options, you can easily dispose of your electronics safely.

LCD Image Persistence

Most people have heard of screen burn-in. It is an imprint of an image on a display that is caused by that image being displayed too long. CRT burn-in was very common for things like taskbars that were always displayed on the screen in the same place. To prevent this, screen savers were invented to display different images to counteract the burn-in effects. Most people thought this problem went away when LCDs were created but that isn’t entirely true. It is uncommon in LCDs but it can happen.  The crystals change their natural state enough to cause an imprinting of the persistent image, kind of like a shadow of it.

See the LCD screen to the right which has a menu at the top that still displays on a blank screen.

Prevention

Much like CRT burn-in, screen savers can help prevent the problem.  It is a good idea to pick a screen server with lots of changing colors.  Having your screen auto turn off when not in use will also help by not displaying the image more than it has to be.

Fixing

Unfortunately, preventative techniques will only do so much if you are always at your computer and not giving it an opportunity to turn off or run a screen saver.  In that case, you need to know how to fix the problem.  It is important to try to fix it as soon as you notice it as it is possible to become permanent if it continues too long.  To fix it, you can try one of these following techniques:

  1. Leave your monitor off for very long periods of time.  This could take hours or many days.
  2. Use a screen saver with lots of colors and let it run for a long period of time.  The length of time can vary depending on how bad the persistence is.
  3. Display a solid single color or white for a long period of time.

If none of those work, your image is probably permanent and you are at your computer far too often.

Small Multifunction Printers

At Tech DC, we regularly set up printers for individuals and businesses. One of our favorite workhorse printers is the multi-function laser printer by Brother called the MFC-7440N, available for $230.

Laser Printers versus Ink Jet

Most customers purchase ink jet printers because their initial cost is low. Manufacturers make their money on the back-end, through inflated prices on the ink. Therefore any volume of printing quickly makes ink jets more expensive. Ink jets typically break more easily and have problems with printer heads drying out. They also do not have as fine of print as laser printers.

The one advantage of ink jets is in printing photos. But it is usually far cheaper to print photos at a Target, Sams, Costco, or drug store.

Brother MFC-7440N

The MFC-7440N is a recent update by Brother from the MFC-7820N. Yes, it’s an upgrade even though the model number went down.

As a multi-function printer, the MFC-7440N prints, faxes, scans, and makes copies. It is very small (15.6 D x 16.9 W x 12 H inches) and can be sufficient for small offices with occasional printing needs. The 250 sheet paper tray makes it less practical for larger volumes.

Networking

The printer includes an ethernet jack and works easily over a network. If you need wireless, consider the Brother MFC-7840W which adds wireless connectivity.

These network printers work with PCs and Macs.

Other Options

Brother also makes larger multifunction printers that add duplex print (double sided printing) options.

Brother laser printers have usually proven to be the most cost effective for our computer support clients. Samsung also makes good printers, but we have found their small mutifunction printers to be somewhat cheaper, both in price and quality. Our experience is that HP’s small multifunction printers are more expensive and provide no greater quality.

Acer Aspire One RAM or Hard Drive Upgrade

Aspire One Upgrade Options

The Acer Aspire One comes with 1GB of RAM and a 160GB SATA Hard Drive.  For an idea of its performance, please check out this video.  RAM can be upgraded to 1.5GB by replacing a 512MB stick with 1GB. We recommend the Kingston PC2 4200 1GB Laptop Memory.  The hard drive can be upgraded with another 2.5 inch SATA hard drive such as the Western Digital 320GB 5400 RPM Scorpio.

Performing these upgrades are not a simple matter as you have to completely take the netbook apart.  Do this at your own risk.  It is also a lengthy process so be sure you set aside a good hour of time.

Requirements

Once you’ve picked out your new RAM or hard drive, you’ll be ready to begin the upgrade.  In addition to a screwdriver, you will need a credit card.  You may also want some bowls to organize screws that get removed and enough space to place removed components.  It is also a good idea to use a towel to cover the screen during the process.  If you are upgrading the hard drive, you will be losing all the data on the included drive.  If you are installing from scratch, then you have nothing else to do.  If you want to duplicate the included OS on the original drive, you will need to run the dd linux command to copy it to your new drive.  To do this, you will need a 2.5 inch external USB SATA enclosure to put the new drive in to copy to.  If you are unfamiliar with this, it is a very similar process to duplicating the drive in a Tivo.


Step 1 – Remove bottom screws 

Flip over the Aspire One so that the bottom is accessible. There are 6 obvious screws to remove on the bottom of the Aspire One.  In addition to that, there are two hidden screws under the back rubber feet.

You will need to peel off the back rubber feet to get to those screws.  I used pliers to slowly peel up the rubber feet.  Try to not touch the sticky side so that they can be reapplied after.  When done, they reapply rather easily.  The 3 screws from the back and front are different sizes to be sure to organize them correctly.
Step 2 – Lift up keyboard 

Flip the Aspire One over so the keyboard is facing up.  There are three clips holding the keyboard down by the F2, F8, and Pause keys.  You need to push these clips back and down with a credit card so they are no longer visible.  After doing this, the clips may pop back up and need to be redone.  Once they are all back, you can slide the credit card under the keyboard to pry it up.  Do not put the credit card under the keys but under the keyboard.  You can then slide the credit card around the sides prying the entire keyboard up.
Step 3 – Unplug keyboard and remove more screws 

Lean the keyboard forward to expose where it is plugged in towards the center.  This cable is held down with a clamp that is on top of it.  You can flip this up to release the connector.  The keyboard should now be loose and can be put aside.  Right below the keyboard connection is a smaller similar connector for the trackpad.  In the same manner, flip up the clamp which will release the trackpad cable.
Step 4 – Remove top panel surrounding keyboard 

Towards the back left above the AC plug is the best place to start prying open this panel.  Push the credit card between the panel and the base to begin prying it open.  Then slide the card completely around the panel which will free it so it can be removed.
Step 5 – Unplug, unscrew, and remove motherboard 

The video cable is towards the upper left. It is held down with tape so first pull up the tape and then pull out the connector.  Towards the bottom middle is another cable held down with black tape.  Lift up the black tape and then slide out the connector leaving the cable dangling.  Towards the bottom right is the Wi-Fi card.  To the right of the card are 2 cables plugged into it.  Unplug these by pulling them directly up then leave them dangling.  The Wi-Fi card is held in with one screw.  Unscrew it and the card will be easy to remove so you can set it aside.  There is a main board to the left and a daughter board to the right.  The main board has just one screw towards the bottom and the daughter board has three screws.  All of these screws need to be removed.
Step 6 – Replace RAM and/or Hard Drive 

You can now flip up the boards to expose the underside where the RAM and hard drive are.  The RAM is on the left and is held down in the typical way with prongs on the sides.  Remove the 512MB card and insert your 1GB card.  It is in properly if the prongs fit into the notches on the card.  The hard drive is to the right and can be separately unscrewed to replace.
Step 7 – Put it all back together 

By this point, hopefully you’ve kept all the components and screws well organized because you just have to do everything in reverse.  When putting the boards down, be sure you have everything flush and tightened so there is enough room for the keyboard to go back in on top of it.  Don’t forget to plug all connectors back in so review the above steps to be sure you do.  The panel around the keyboard will snap in as will the keyboard itself by applying a little pressure.  Before screwing in the bottom screws, you might want to boot up to make sure everything is working.
