If you’re disposing of old documents such as bank statements and tax forms, security experts recommend shredding the paperwork so it can’t be used by identity thieves. Simply deleting the data by emptying the “trash” folder won’t totally wipe all that information away.
Before you dispose of an old personal computer, the experts recommend that the very least you do is reformat your hard drive and reinstall the operating system. A better bet is to wipe your hard drive clean. It’s a practice everyone should be familiar with, since it may be the top recommendation for preventing identity theft.
However, many consumers and organizations are turning to a paperless world, and records once held in filing cabinets are now stored on computer hard drives. But computers eventually get replaced, and old computers are donated, recycled, handed down or refurbished — often with personally identifiable information (PII) still on the machine.
An even easier way to do this, provided the user has Windows Vista or better, is to create a system repair disk and then format the hard drive using the standard format command.
Make sure that the computer technician is one who understands that deleting a file, formatting a hard drive or reinstalling an operating system doesn’t render the data unrecoverable. Those technicians will know enough to identify the proper tools to wipe your drive.
Eliminating personal data from personal computers kept at home is relatively easy. The real problems lie with mobile devices and work computers. Smartphone and tablet owners now store a great deal of personally identifiable information on these devices.
Apps are available to “wipe” the devices if they are lost or stolen, but the technology is still relatively new and these apps leave some data behind. Ideally leave your banking, personal emailing and social networking to your home computer. That way, you can control what happens to your personally identifiable information when the time comes to get rid of your old equipment.

You adore your laptop. It lets you get down to business wherever you happen to be—airport lounge, coffee shop, your home office. It’s the key to your competitive edge.
That is, until its battery croaks. Just as you’re putting the final details on your PowerPoint presentation. At the airport. Two hours before takeoff. And with no power outlet in sight. At that instant, you begin to wonder why you ever bought the ever-lovin’ boat anchor in the first place.
But love will bloom anew as soon as you recharge. Avoid the heartache, however temporary: Follow these five tips for maximizing your laptop’s run time.
1. Plug in whenever possible
One surefire way to ensure that your laptop is always ready for action is to plug it into an AC outlet whenever possible. Keeping the machine fully charged makes it far more likely that you will always have the juice you need to complete your work. Purchase at least one extra AC adapter, so you’ll always have one in your office and one in your laptop bag for travel. If you work at home frequently, consider buying a third adapter to leave there.
Terminate the offending process by right-clicking it and selecting ‘Kill Process’
A common misconception about laptops is that leaving the system plugged into AC power continuously will overcharge or shorten the life of its battery. Given that the lithium cells used in modern laptops will either catch fire or explode if overcharged, this is obviously not true. Lithium ion batteries stop charging once they reach full capacity, and keeping the battery charged reduces wear and tear on the power source, lengthening its useful life span.
2. Adjust the screen brightness
Modern displays with LED backlights are a major improvement over the CCFL (cold cathode fluorescent tube) backlit displays of yesteryear, in terms of both picture quality and power efficiency. Still, a laptop’s display claims a significant percentage of the power that the system consumes. As such, keeping the screen backlight low can increase your laptop’s run time noticeably. You should also take care in choosing where you work: A low backlight setting will be far more comfortable in a café with soft lighting than in a brightly lit room.
Another way to reduce the power the display consumes is to tweak the automatic backlight controls in Windows. Open Control Panel, choose Hardware and Sound > Power Options, and click Change plan settings for the active power plan. Choosing an aggressive timeout of 1 to 3 minutes under the ‘Dim the display’ and ‘Turn off the display’ options while the machine is operating on battery power will eke out more battery life by dimming or switching off the screen after the specified amount of inactivity. You can also click the Change advanced power settings option to set the level of brightness when the laptop is in the dimmed state.
3. Track down errant apps
One culprit often responsible for draining the battery ahead of its time is the presence of errant software applications that suck up disproportionate processor cycles. Unnecessary utilities running in the background, or an app that is hanging, can also cause this effect. Web browsers are particularly prone to the latter problem, due to the multiple plug-ins, rendering engines, and scripting engines embedded within them.
Modern CPUs save power by dynamically scaling back their clock speed to the minimum possible, but they can do so only when apps aren’t active. If you fail to deal with rogue apps, they will not only drain battery power—they might also slow down your entire system. One clue to the existence of an errant app is if your laptop fan frequently kicks into high gear when the machine should be idle.
Resolving the problem is relatively straightforward: Press the Ctrl-Alt-Delete key combination, launch Windows Task Manager, and use it to identify processes that are showing unexplained high utilization. If a program won’t exit normally, terminate the offending process by right-clicking it and selecting Kill Process. For Web browsers, shutting off all instances usually works. Should all else fail, perform a system restart.
4. Disable intensive background apps
Errant apps aside, applications that make intensive use of the processor or network should remain closed when your laptop isn’t plugged in. Peer-to-peer software such as BitTorrent clients and computationally intensive applications such as distributed-computing projects (Folding@Home, for example) are out. You can also confirm that Windows Update and other software updaters are not attempting to download large software patches.
Disabling automatic Windows Update functions outright is too draconian (particularly if you forget to reinstate the feature later), but periodically checking on your network usage for unexplained spikes will allow you to identify and stop large file transfers before they gobble up precious minutes of battery life.
5. Disable unneeded devices
You can disable unneeded hardware devices or ports to squeeze out a few more minutes of power, although this option isn’t possible with every laptop. Start by disabling unneeded wireless capabilities, such as built-in data modems and Wi-Fi and Bluetooth radios (many laptops have hardware switches for this purpose).
The optical-disc drive is another power guzzler that can drain batteries fast, so don’t leave a DVD or Blu-ray disc in the drive if you don’t need it. Finally, many laptops these days come with backlit keyboards; these are great when you’re in a dark environment, but you can save precious power by doing without the feature when your laptop is running on battery power.

Most of us let our Desktop or Laptop run for days…weeks..or even years put together. Is it safe? will that impact my data? will that impact its performance? We at Stellar Phoenix face many such questions on daily bases. There is nothing wrong in leaving a machine run for extended hours. A computer has more detrimental impact from electrical spikes and failure of drives etc than simply leaving the PC running.
Heat can be your biggest enemy. You will find that even with the energy new conservation settings available, heat is produced when power is consumed. Yes with proper ventilation the IC components will remain in the tolerable operating range of temperature. However life span is shortened by heat. However variance in temperature from shutting off, then turning on (cool/hat) also damages the chips lifespan.
The most important component that is affected mostly is the hard drive unfortunately its the worse component to crash because it holds all your important data. A hard drive usually is made for 3000-5000 hours of normal usage. Hard drive manufactures offer 3-5 years of manufacture warrantee but Customers replace disk drives 15 times more often than drive vendors’ estimate, according to a study by Carnegie Mellon University. The comparatively high replacement rates are not surprising because of the difference between the “clean room” environment in which vendors test and the heat, dust, noise or vibrations in an actual work environment. Experts have also seen overall drive quality falling over time as the result of price competition in the industry.
We can also argue that the same hard drives are part of these sophisticated servers and they run for years put together then why will the same hard drive crashes in my desktop or laptop?
Server rooms have anti-static floor finishing, maximum electrical intensity of computing equipment of 300 watts per square foot, heating, cooling and humidity controlled environment 72°F (+/- 2°F) and 45% RH (+/- 5%). Nothing like an actual daily work environment.
We at Stellar Phoenix would suggest one should not let a machine run un-attended for hours together. One should always shutdown of not then leave your machine on hibernate mode to avoid any permanent data loss.
