I recently worked on an Acer Aspire One Netbook (Model AOD150). The netbook was no longer able to boot, as the system could not find an operating system. Booting the netbook up onto a USB drive, I was able to see the problem. The hard drive had two partitions, one hidden recovery partition and one active system (C:\) partition that had become corrupt.

The only solution was to use the recovery media. Only the owner did not have an external CD / DVD writer, so she could not create the recovery media. I contacted Acer, and they sent out new media for free. I got the media and reloaded the netbook, and all was well. I had a chance to work with it a little bit and liked the size, battery life, and cost. So I decided to pick one up.

I purchased an Acer Aspire One Netbook (Model AO571h). After allowing the system to restart a couple of times for set up, it was ready to go on first boot. I proceeded to connect a DVD writer and created the recovery media. I then decided to look at the hard drive partitions, so I put a bootable cd in the external optical drive I just used to create the recovery media and reboot.

Booted the netbook up on a PE (preinstall environment) cd, and all looked fine. The netbook had two partitions, one hidden recovery partition at 8 gigabytes and one active system (C:\) partition at 141 gigabytes, for a rough total of 149 gigabytes. That was correct for a 160 gigabyte hard drive once formatted.

I turned off the netbook and external DVD drive, disconnected the DVD, and restarted the netbook. What happened next was deja vu. The screen displayed cannot find operating system error. I turned it off, reconnected the external DVD drive, and proceeded to reload the system with the disks I had just created.

I reloaded the netbook and then checked the hard drive. This time there was only one active system (C:\) partition at 149 gigabytes. The system works fine and has had no problems since.

Remember, if your new laptop, netbook, or personal computer does not come with recovery media (disks), you probably have to make them yourself. This is the first thing that should be done. Luckily for me, that's just what I did.

With the Windows 7 test system running, it's time to see what it can do. Keep in mind that the total cost for just the hardware (less the Antec Skeleton case) was around $525. I went over to Adobe and downloaded the 64-bit trial version of Photoshop CS4. The following is an excerpt from Adobe's knowledge base article '64-bit Operating System benefits and limitations in Photoshop CS4 (Windows)'

Opening 32-bit and 64-bit versions

Photoshop installs a 32-bit and a 64-bit shortcut into the Start Menu. If you need to manually run the application, the 32-bit version is the photoshop.exe file, in the Program Files (x86)/Adobe/Adobe Photoshop CS4 folder, and the 64-bit version is the photoshop.exe file in the Program Files/Adobe/Adobe Photoshop CS4 folder.

Third party plug-ins

Third party plug-ins written for 32-bit versions of Windows will not work when you run the 64-bit version of Photoshop. If you need to use plug-ins that haven't been updated, run the 32-bit version of Photoshop. When you are done using the plug-ins, close the 32-bit version, and run the 64-bit version. Contact the plug-in manufacturer for information about any updates.

Processor speed and Photoshop operations

Although the 64-bit version of Photoshop will speed up some operations, it won't speed all of them, nor will it speed the operation equally. Generally, operations will run approximately 8-12% faster. Overall, processor speed is not the main advantage of using the 64-bit version.

RAM use

The primary advantage of using the 64-bit version is to access amounts of RAM beyond what Photoshop can access when the 32-bit version is run. You can take advantage of more than 4 GB of RAM only when you are on 64-bit Windows, using 64-bit Photoshop. If you use files large enough to need more than 4 GB of RAM, and you have enough RAM, all the processing you perform on your large images can be done in RAM, instead of swapping out to the hard disk.

This table lists the amount of RAM available to Photoshop with the different versions of Windows:

Now with the two different versions of Adobe Photoshop installed (32-bit & 64-bit) it was time to find a benchmark test. I found DriverHeaven Photoshop Bench V3. I ran the tests as instructed and here's the results:

As you can see, the 64-bit version was, on average, 7% faster than the 32-bit version.

I have now shown you the pros and cons of 32-bit and 64-bit versions of Adobe Photoshop CS4 running on Windows 7. Which version would you choose?

Till then,

Task Manager provides information about programs and processes running on your computer. It also displays the most commonly used performance measures for processes.

You can use Task Manager to monitor key indicators of your computer's performance. You can see the status of the programs that are running and end programs that have stopped responding. You can also assess the activity of running processes using as many as fifteen parameters.

In addition, if you are connected to a network, you can view network status and see how your network is functioning.

If you have more than one user connected to your computer, you can see who is connected, what they are working on, and you can send them a message.

Open Task Manager:

• To open Windows Task Manager, right-click an empty space on the taskbar, and then click Task Manager or by pressing CTRL+SHIFT+ESC.

Note:
You might need to be logged on as an administrator or a member of the Administrators group in order to perform some tasks.

Monitoring Sessions

This video gives an overview of the key features that I built the Windows 7 test system to evaluate, Quad-cores, 64-bit operating systems/applications, and Virtualization Technology (Virtual Machines).

I little while back, I wrote an article on using Dual Monitors. In it, I wrote how a person with a visual impairment could use two monitors. Here's a snippet:

"This scenario also works well for those with visual impairments that require a magnification utility. You can use a larger monitor as the ‘main’ display and a smaller monitor as the ‘secondary’ display. Using the main display for all standard functions, the secondary display shows a magnified view of the main display. And without the need for matching monitors, you could pick up a cheap used one to run as secondary. Try your local Goodwill, Savers, thrift shop, etc."

Here's a video showing how to use dual monitors in Windows for users who have impaired vision.
