Extend Your Laptop's Battery
2. Dim your screen - Most laptops come with the ability to dim your laptop screen. Some even come with ways to modify CPU and cooling performance. Cut them down to the lowest level you can tolerate to squeeze out some extra battery juice.
3. Cut down on programs running in the background. Itunes, Desktop Search, etc. All these add to the CPU load and cut down battery life. Shut down everything that isn’t crucial when you’re on battery.
4. Cut down external devices - USB devices (including your mouse) & WiFi drain down your laptop battery. Remove or shut them down when not in use. It goes without saying that charging other devices (like your iPod) with your laptop when on battery is a surefire way of quickly wiping out the charge on your laptop battery.
5. Add more RAM - This will allow you to process more with the memory your laptop has, rather than relying on virtual memory. Virtual memory results in hard drive use, and is much less power efficient. Note that adding more RAM will consume more energy, so this is most applicable if you do need to run memory intensive programs which actually require heavy usage of virtual memory.
6. Run off a hard drive rather than CD/DVD - As power consuming as hard drives are, CD and DVD drives are worse. Even having one in the drive can be power consuming. They spin, taking power, even when they?re not actively being used. Wherever possible, try to run on virtual drives using programs like Alcohol 120% rather than optical ones.
7. Keep the battery contacts clean: Clean your battery’s metal contacts every couple of months with a cloth moistened with rubbing alcohol. This keeps the transfer of power from your battery more efficient.
8. Take care of your battery - Exercise the Battery. Do not leave a charged battery dormant for long periods of time. Once charged, you should at least use the battery at least once every two to three weeks. Also, do not let a Li-On battery completely discharge. (Discharing is only for older batteries with memory effects)
9. Hibernate not standby - Although placing a laptop in standby mode saves some power and you can instantly resume where you left off, it doesn’t save anywhere as much power as the hibernate function does. Hibernating a PC will actually save your PC’s state as it is, and completely shut itself down.
10. Keep operating temperature down - Your laptop operates more efficiently when it’s cooler. Clean out your air vents with a cloth or keyboard cleaner, or refer to some extra tips by LapTopMag.com.
11. Set up and optimize your power options - Go to ‘Power Options’ in your windows control panel and set it up so that power usage is optimized (Select the ‘max battery’ for maximum effect).
12. Don’t multitask - Do one thing at a time when you’re on battery. Rather than working on a spreadsheet, letting your email client run in the background and listening to your latest set of MP3’s, set your mind to one thing only. If you don’t you’ll only drain out your batteries before anything gets completed!
13. Go easy on the PC demands - The more you demand from your PC. Passive activities like email and word processing consume much less power than gaming or playing a DVD. If you’ve got a single battery charge - pick your priorities wisely.
14. Get yourself a more efficient laptop - Laptops are getting more and more efficient in nature to the point where some manufacturers are talking about all day long batteries. Picking up a newer more efficient laptop to replace an aging one is usually a quick fix.
15. Prevent the Memory Effect - If you’re using a very old laptop, you’ll want to prevent the ‘memory effect’ - Keep the battery healthy by fully charging and then fully discharging it at least once every two to three weeks. Exceptions to the rule are Li-Ion batteries (which most laptops have) which do not suffer from the memory effect.
Bonus Tip #1: Turn off the autosave function. MS-Word’s and Excel’s autosave functions are great but because they keep saving regular intervals, they work your hard driver harder than it may have to. If you plan to do this, you may want to turn it back on as the battery runs low. While it saves battery life in the beginning, you will want to make sure your work is saved when your battery dies.
Bonus Tip #2: Lower the graphics use. You can do this by changing the screen resolution and shutting off fancy graphic drivers. Graphics cards (video cards) use as much or more power today as hard disks

How to Delete A File That Won't Delete
Have you ever wanted to delete a file, but Windows wouldn’t allow you to do it? These things happen to me all the time, especially when I’m at a client’s house trying to get their machine clean of spyware.
The main reason behind this is that the explorer.exe process locks files that are in use, effectively preventing you from deleting them. Usually, these files should not be touched, but sometimes, situations arise when you really need to get rid of some troublesome ones.
Fortunately, there are a few easy solutions around this problem.
Solution #1: Kill explorer.exe
Solution #2: Use The Windows Recovery Console
Just stick your Windows CD in your CD tray, boot on it, and at the “Welcome to Setup” screen, press “R“. Once the recovery console has started, navigate to the location of your locked file, and delete it.
Solution #3: Use unlocker
Unlocker is a very useful freeware that will allow you to unlock any files that are currently in use by Windows. You’ll know if this is happening if you are getting any of these messages when trying to delete a file:
- Cannot delete file: Access is denied
- There has been a sharing violation
- The source or destination file may be in use
- The file is in use by another program or user
- Make sure the disk is not full or write-protected and that the file is not currently in use
Unlocker will make things right again for you.
You’ll notice that right after installing the software, a new option named “unlocker” will appear when right clicking any files or folders in Windows Explorer. To unlock a locked file, just right click it, select unlocker, and the unlocker software will start. Then, click “unlock all” and close the software. Now that your file is unlocked, just delete it in Windows Explorer, as you always do.
Personally, I find this a much easier solution than the first two options.

Internet Explorer 7 Scam!
An official-looking graphic has been circulating around the Internet, soliciting users to download "Internet Explorer 7 Beta 2"--a release that is now quite outdated. Users who click on the ad are immediately prompted to download a file called "ie7.exe," which is in reality--you guessed it--a Trojan horse. Don't do it. The real IE7 update should be obtained by using Windows Updates.

Wireless Network Security
There are two main ways to go with wireless security, WEP and WPA.
WEP (Wireless Encryption Protocol ) is "ok" for the average user. It keeps the neighbors out and most drive by stalkers looking for an unsecured connection. This protocol can be hacked though by hackers using free tools that are widely available if you know where to look.
WPA is a randomized pre-shared key of at least 10 characters and would take half-a-million years to crack. (Note: A random key means that it shouldn’t be a word that exists in any dictionary (hackers have extensive dictionaries that include all common passwords, English words, nicknames, and misspellings of words. This is called a “dictionary attack.”) A random key is a meaningless mix of lower- and uppercase letters and numbers, and sometimes special characters like punctuation, depending on whether your router supports it).
Never use words, birth dates or even misspelled common words or names.
Disable SSID broadcasting and set a password for accessing your router's configuration screens.
Encrypting your wireless network is not as complicated as it may seem on the surface and is an important step of your your wireless setup. If you just don't feel confident doing it yourself then you should call a knowledgeable installer to do the job for you.
Wireless network installations and securing is just one of the many services that we provide for our clients. Check us out at www.davtechsolutions.com and give us a call to set up your wireless network securely.

New Vulnerability in IE6
The code exploits a recently patched flaw in Internet Explorer. The code could be used to run unauthorized software on a computer that was not updated with the latest Microsoft patches. A patch for this has been released, but now that hackers know where the weakness is there will be more attention to it.
IE7 has been out for a while now and is a decent browser go ahead and update to it or try Firefox which is even better and very secure. You can download the Firefox browser from our web site, www.davtechsolutions.com
