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.

You work hard to protect your PC from the malicious thugs of our digital world. You keep your antivirus program up to date. You avoid questionable Web sites. You don’t open suspicious email attachments. You keep Java, Flash, and Adobe Reader up-to-date—or better yet, you learn to live without them.
But against all odds, a clever new Trojan horse slipped through the cracks, and now you’re the unhappy owner of an infected PC. Or perhaps a less-vigilant friend has begged you to clean up a plague-ridden mess.
Obviously, you need to scan the computer and remove the malware. Here’s a methodical approach that you can use to determine what the problem is, how to scan, and what to do afterward to protect the PC from future invasions.
- Verify the infection: Is the PC in question really infected? I’ve seen people blame “another damn virus” for everything from a bad sound card to their own stupidity. The first step in restoring the system’s health is to determine whether what you’re dealing with is a virus rather than a problem with hardware, software, or user error.
If your PC is unusually slow, or if it seems to do a lot of things on its own that you haven’t asked it to do, you have reason to be suspicious. But before you decide that a virus must be responsible, take a moment to launch the Windows Task Manager (right-click the Windows taskbar, and select Task Manager from the pop-up menu). Open the Processes tab, and check for any strange or unknown applications running in the background—especially those with nonsensical names and no recognizable authority listed in the description. The odd-looking “wuauclt” process is fine, for example, because it belongs to Microsoft (it’s actually part of the Windows Update service, as you can tell from the description.)
Of course, this is only general guidance; there’s nothing to stop a piece of malware from masquerading as a legitimate process by sporting an inoffensive description. That said, you’d be surprised how often a piece of malware gives itself away with a line of strange characters or symbols where the process description should be.
- Check for sure signs of malware: Truly insidious malware will preemptively block you from trying to remove it. If your PC suddenly won’t load utilities that might help you manually remove malware—such as msconfig or regedit—be suspicious. If your antivirus program suddenly stops loading, that’s a huge red flag.
Sometimes the attack is more obvious. If a program you don’t recognize suddenly pops up and starts displaying dire warnings and asks you to run an executable file or asks for your credit card number, your PC is definitely infected with some nasty malware. Never fork over your credit card information or other personal data to a program or website that tries to warn you that your PC is about to die. More often than not it’s a rogue program, fear-mongering malware that tries to scare you into giving up your private info by issuing doomsday warnings of imminent hard drive failure, catastrophic viral infection, or worse.
- Check online for possible fixes: The one benefit of those scary pop-ups is that they could point you toward a cure. Use your favorite search engine to look for phrases that appear in the pop-up—you’ll probably find other people fighting the same infection. Their experiences could help you identify your enemy or even find step-by-step instructions for removing the malware. Be prudent: Take advice only from sites that seem reputable, and remember to perform a full scan of your PC after you’ve followed any instructions, even ours.
Barring any clues that lead you to a magic solution, scanning becomes your next and most important step.
- Assume that your old virus scanner is compromised: Don’t waste time scanning your hard drive(s) with your regular antivirus program. After all, that program probably failed to catch the malware in the first place.
But don’t be too hard on it. Nothing’s perfect, and even the best antivirus program can occasionally miss a new or particularly cleverly designed virus. And once that virus slips through, your antivirus program is compromised. You have to assume that the malware, not the security software, is in control.
You need a fresh malware scanner—one that’s not already installed on your computer. It must be capable of detecting and removing malware from your PC, and you need to run it in an environment where the malware can’t load first. Linux is your best bet, but before you jump to that option, try booting into Windows Safe Mode to see if you can outflank your virus infestation there.
- Use a lightweight scanner inside Safe Mode: Windows has a Safe Mode that boots a minimal version of the operating system, with generic drivers and nothing else. It doesn’t load most startup applications and—most likely—it won’t load the malware that’s infesting your PC.
To enter Safe Mode, boot your computer and press the F8 function key before Windows starts loading. The timing is tricky, so it’s best to mash F8 repeatedly from the moment the motherboard manufacturer’s logo appears onscreen until you get the boot menu.
When you reach that menu, select Safe Mode with Networking from the list of boot options. The with Networking part is important—you’re going to need Internet access to solve your virus problem.
Once in Safe Mode, open Internet Explorer (using other browsers in Safe Mode is often problematic) and run a reputable online virus scanner. Use a web-based virus detection app that is always up-to-date and runs off a remote server. You’ll have to accept a browser add-in, but the scanner should remove it when it’s done. Before you start the scan, click Advanced settings and enable as many extra levels of scrutiny as you can, including scanning file archives and browser data.
You might also try Trend Micro’s HouseCall. Though it isn’t a Web app, it is portable, so you can download HouseCall on another computer and copy it to a flash drive, thereby creating a portable PC virus scanner. Then, when you run into trouble you can plug the flash drive into the infected PC and run the program from there (you’ll still need an Internet connection for a definition update, however.) When using HouseCall, don’t run it on default settings: Before you click the big blue Scan Now button, click Settings and select Full system scan.
Whichever scanner you use, don’t rush to get through this part of the process. Check the options and select the slowest, most thorough scan. Then, once the scan has started, step away from the PC. Read a book. Do the dishes. Spend time with someone you love. The scan will—and should—take hours.
- Remember- The second scan’s the charm: When that first scan is done—just to be sure—run another one with a different scanner.
It’s easy, and you’ll sleep better after multiple scanners have assured you that your drive is clean.
- Look to Linux as your last line of defense: Booting into Safe Mode may not short-circuit particularly malicious malware. If you still have trouble with an infection after running multiple scans in Safe Mode, you’ll have to bypass Windows altogether and avoid booting from the hard drive. To manage that trick, use a bootable CD or flash drive running a Linux-based antivirus utility.
You don’t have to know Linux to take this step. But you will want an Internet connection, since these scanners must go online to update their malware databases.
The first step is to download a bootable virus scanner as an .iso file. From it, you can easily create a bootable CD. In Windows 7, double-click the file and follow the prompts. In Windows 8, right-click the file and select Burn disc image. For earlier versions of Windows, you’ll need a third-party program such as the free ISO Recorder.
- Protect your newly disinfected PC: When you’re satisfied that your drive is clean, try rebooting into good old Windows. Then uninstall your old antivirus program—it has been compromised.
Of course, you don’t want to stay unprotected. Reinstall the program and update to the latest version, or (if you’ve lost all faith in it) install a competitor.

Because when it comes to malware, a byte of prevention is worth a terabyte of cure.

If you are upgrading from one old computer to other or When you or one of your employees gets a new company computer, you might need to transfer a large amount of data from your old computer to the new computer. The fastest and easiest way to transfer from PC to PC is to use the company’s local area network as the transfer medium. With both computers connected to the network, you can map the hard drive of one computer as a hard drive on the other computer and then drag and drop files between computers using Windows explorer.
Access the old computer and look up the computer’s IP address. Click “Start” and select “Control Panel.” Click “Network and Sharing Center.” Select “Change Adapter Settings” from the menu on the left.
Locate the icon with blue-colored screens that does not have a red “X” next to it. For example, choose “Local Area Connection.” Right-click the icon and choose “Status.” Click “Details…” and record the number on the line labeled “IPV4 Address.” An example would be “192.168.1.100.” Click “Close” on the Details window and “Close” on the Status window.
Determine the drive on the old computer that has files you want to transfer to the new computer.
Access the new computer. Click “Start” and select “Computer.” Choose “Map network drive” from the menu. Choose a drive letter in the Drive box.
Enter the address of the old computer in the box labeled “Folder.” Type two backslashes, the IPV4 address of the old computer, another backslash, the old computer drive letter and a dollar sign. For example, type “\\192.168.1.100\c$” (without the quotes). Click to remove the check mark from the box labeled “Reconnect at logon.” Click “Finish” to initiate the connection to the old PC.
Enter a username and password that has administrative rights to the old computer when the system prompts you to sign in. Click “OK” to complete the drive mapping and open a window with the contents of old computer drive “C:.”
Click “Start” and select “Computer” on the new computer to open a second Windows Explorer window. Position the two windows so you can easily drag files back and forth between them. Locate the files you want to transfer. Drag the files from one window to the other to copy them from one PC to the other.
Make sure you always open ALL THE FILES you just transfer before deleting any from the original destination to avoid any data loss. As per a recent study 40 – 50% of all backups are not fully recoverable and up to 60% of all backups fail in general.
Disasters that threaten a business can happen anywhere at any time. But no matter how it is caused, a loss of data, or access to data for any kind of extended period, inevitably means a loss of revenue, a loss of productivity, a loss of reputation, and increased costs.
When in doubt contact Stellar Phoenix Solutions.
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.
