COMPUTER TIP #15: IT’S O.K. TO MAKE MISTAKES, JUST BE CONSISTENT: We all make mistakes, even more so when operating our computers. And, eventually, you’ll require professional computer help, either from a help line or a service call. Here’s a tip from your friendly computer pro: Nothing makes it harder to correct mistakes than when the client makes the same error in numerous, different (and often quite creative) ways. This usually means that we have to find and correct each individual way that the user has made the error. If at all possible, be consistent in the error that you make, even if it’s wrong. That way, we only have to correct one problem. For example, if you’re having a problem with an accounting, word processing or spreadsheet program, try to use the same accounts or formulas and save in the same locations consistently; it’ll make it easier to correct if need be.

COMPUTER TIP #16: TIP FROM THE “IF IT’S NOT BROKEN, DON’T FIX IT” DEPARTMENT: You’ll notice a commonality in the Hoaxes, Security and News pages of this site. It involves the pressure to upgrade software (such as drivers or web or video software) or to install new software (for example, in order to view certain types of video or graphics on a web page, or to install the “latest version” of, say, AOL (which may not even be compatible with your operating system, which they forget to tell you). Think twice before doing so: If everything is working fine on your computer, my recommendation is to leave it alone! You don’t need to upgrade, no matter what you’re told. If you’re told to download and install software to view or play a webpage or a file, think twice - - There’s a very strong chance that your download may include malware. Unless it’s from a major player such as Adobe, Macromedia or the like (you can verify this by going to their Home, then Download pages) you should be aware of the risk. Rethink how badly you really want to view that web page! So far as enabling the device driver update feature in Windows 7, or just updating drivers when Windows notifies you that they’re available, you can look at it two ways: First, If Microsoft updates the drivers, they may be more compatible with the operating system. Of course, they may also be stripped down drivers without the full features of the vendor’s driver. I just install and leave things be unless there’s a malfunction. Moreover, you should be aware that updating some third-party (non-Microsoft) drivers can cause your computer to demand re-activation of your operating system because Windows Product Activation (“WPA”) detects hardware changes and thinks you’ve illegally transferred the operating system to a new (second) computer.

COMPUTER TIP #17: HOW DO I CLEAN AN LCD MONITOR: Cleaning the glass on a CRT monitor is easy - just spray with glass cleaner! But an LCD monitor is a different animal - it’s usually covered with plastic. You don’t want to use any abrasive cleaner, nor do you want to use any cleaner with ammonia or any harsh chemical because it may fog or scratch the plastic coating. You can purchase special cleaners, but it’s really not necessary, because a light mixture of ordinary soap and water will do the trick and not result any damage to the surface of the monitor. Also, never use paper towels or even tissues to clean the monitor because they may cause scratching: Use a soft cloth, such as microfiber. I’ve heard that scratches on the plastic face of the monitor can be removed with automotive plastic dressing, but I’ve never tried it. Finally, when cleaning any parts of the computer, remember to suck out any debris with a vacuum rather than blasting it inside the computer, keyboard or monitor, where it can coat the components, resulting in heat and (if wet by cleaning spray) a short on the circuit board.

COMPUTER TIP #18: DON’T LEAVE EXTERNAL DRIVES ALWAYS ON: If you’ve purchased a USB or SATA external hard drive to back up your computer files on a periodic basis, it’s a good idea to turn them off between backups. Even better, unplug the power plugs as well; the transformer boxes to the power cords aren’t usually very high-end and, with continuous use, can degrade to the point where it won’t send sufficient power to the drive case when you turn it on. It’s almost impossible and quite expensive to find an exact replacement for the transformer box, cord and connector without replacing the entire external drive unit, so play it safe and just unplug the entire device completely unless you’re using it to create a backup. Unlike the components inside of your computer, external drive boards have a limited life which is much shorter than your computer’s motherboard. If you really require continuous backups, consider either installing the backup hard drive internally into the computer or going to a RAID configuration, both of which are built for long term continuous usage. And I don’t recommend the use of flash drives for anything other than the occasional data transfer, as such drives can be notoriously unreliable, failing without warning. Forget any type of magnetic disks (floppies), as they degrade even faster.

COMPUTER TIP #19: BEWARE POWER PROBLEMS WITH USB: With more and more devices (keyboards, mice, scanners, cameras, printers) connecting through the USB port, and the demise of serial, PS2 and parallel ports, there has been greater use of USB hubs to increase the number of USB connections, particularly on older computers. Unfortunately, there can be some loss of power to the USB device from a hub, as opposed to a connection directly to the computer. If your device does not install or is not recognized when installed through a USB hub, try disconnecting and installing directly to the computer. If you have a Type 1 USB connection, make sure you have an electrically powered hub, as opposed to one that gets its power only from the computer itself. Also, the USB ports on the front of your computer are also wired and not “direct” to the main board (into a card slot), so it will may be slower or non-responsive. If the device doesn’t install either way, you can always install a Type 2 USB card directly into a PCI slot on your computer, which would add a number of additional USB ports directly from the main board.

COMPUTER TIP #20: MY PRINTER STOPPED PRINTING, WHAT CAN I DO? This only applies to injket printers: Before bringing it in for service, you should check a couple of things: First, many (but not all) printers can refuse to print at all even if only one of the print cartridges is empty. You may have one of those. If the lights are on, meaning there is power to the printer, you may want to insert new cartridges, it may do the trick. If you haven’t used the printer in a while, the print heads may be clogged. To solve this, remove the cartridges and hold the (usually copper) print head for 15 seconds against a folded paper towel soaked in very hot water. (Watch out not to get the ink on you, your clothes or any surfaces.) Also, some of the printer “toolboxes” have a utility to blow out the printer head (e.g. HP Photosmart Toolbox>Maintenance>Clean Cartridge.) Use this as well. This may loosen any clogs. If the power lights are off on the printer, physically disconnect the power and printer cables, leave off for 15 minutes or more, then reconnect and see if the machine cycles on again. Also, don’t forget to clear the queue (select “cancel all print jobs”) before fixing, or you may print out 100 pages of waiting print jobs from your multiple attempts to print before the repair! If these tricks don’t work, then bring in the printer for service. [Laser printers, because they have fusers, drums, more circuit boards and the like, should always be brought to a professional for service.] Inkjet printers are basically give-aways, the true cost made up on the replacement ink cartridges, so it’s usually less expensive to replace the printer than repair it.

COMPUTER TIP #21: WHERE IS THE “ANY” KEY ON MY COMPUTER? Believe it or not, we are asked this quite often. Of course there is no “any” key; you can just press “any key” on the keyboard. But, just for the sake of humor, here’s what it might look like:

COMPUTER TIP #22: A NOTE ABOUT PRINTERS AND SURGE PROTECTION: While it’s O.K. to plug an inkjet printer into a surge protector, you should never plug your LASER printer into a surge protector or UPS. THE REASON: Laserjets run a repeated heating cycle, drawing current every minute or so, spiking and then going back down again. Your surge and UPS have specific current ratings and usually a circuit breaker as well. The repeated fluctuation can not only trip your breaker and crash your system, depending on the amount of equipment connected into the multi-outlets and the power rating, but the constant adjustment to the protection circuits can also cause tremendous wear to your printer, shortening its life. THEREFORE: Plug your laser printer directly into the wall outlet and not your power adaptor. If possible, try and connect it to a different circuit than the computer itself, although in homes this often isn’t possible.

COMPUTER TIP #23: WHAT IS SYSTEM RESTORE AND WHAT DOES IT DO? System Restore is a very useful feature on many versions of Windows. (The glossary definition states where it can be found if you have this feature.) It is also, however, one of the most misunderstood features in Windows. The original intention of this feature was to correct or “roll back” a corrupt installation of software, updates, drivers and the like. It is used to “restore” the “system” to a previous restore “point” that is either automatically or manually set. System means the “system state,” which includes the registry, COM+ Class Registration database, boot files and certain specific additional file types. [Click HERE for a list of all files, which includes many .exe and .dll file extensions.] But it by no means restores ALL of your files, only a core set of system and application files. It is not a BACKUP of your computer! Most important, it does not monitor changes to your personal data files or programs, such as documents, email, pictures, graphics, internet favorites, cookies, or the like. For example, the My Documents file is not backed up. Nor are data files or programs which may be resident on your desktop. So, if your system has a problem and can be restored to a previous point, the data files and programs will still be current, and will not be restored to an earlier version such as the date of the restore point. For a discussion about operating the System Restore Utility by Microsoft, click HERE. As a practical matter, System Restore shouldn’t be used very often, it at all, as it may make it all but impossible to make further repairs to the operating system after it has been used. Usually, it’s best to use it only after other repair methods have failed, and just before taking the drastic action of wiping the disk and reinstalling everything again.

COMPUTER TIP #24: I CAN RECEIVE EMAIL, BUT SUDDENLY I CAN’T SEND IT. WHAT’S WRONG? This is becoming a common problem, as more and more ISPs are blocking Port 25 of its subscribers computers. Ports are an important part of email communication: To communicate, computers need to know not only the server name (e.g. mail.verizon.net) but also the Port (e.g. 25), kind of like dialing into a large company on the main telephone line (e.g. (941)302-2000), but having to specify a numbered extension (e.g. 1212) in order to be connected to the person you seek. If your party moves extensions, or the extension is pulled from the wall jack, your message won’t get delivered. Similarly, when your ISP changes the mail port, your email will not be delivered either. There was an excellent reason for this: A few years ago, it was discovered that hundreds of millions of spam emails were being transmitted over Port 25 each day. So many of the ISPs changed their Outgoing Mail Server to stop the spam. Many, such as Comcast, have switched to Port 587. Verizon, Port 1025. Others use Port 2525. Often, you receive no notice from your ISP, but if you call tech support, they’ll tell you what to do. Resetting the port is relatively easy: In your email program, go to the Internet E-mail Settings window, to the Advanced tab, and change the port number within the Outgoing Server (SMTP) box. Also, don’t forget to go to the Outgoing Server tab and check the box that says “My Outgoing Server (SMTP) Requires Authentication” as well. Save and exit all windows and you should be good to go. [Further information, click HERE and HERE.] Aside from this problem, the most common cause for this type of sending error is that the e-mail address you are using is incorrect: Either it contains an improper character (i.e. a “+”, or “=”, or “\” or something like that) or a space, or else the address is no longer valid because the recipient has possibly changed providers. This type of problem is usually the senders fault - erase the mail from your Outbox, or copy it to the Draft box then correct the e-mail address.

COMPUTER TIP #25: WHAT TO DO IF YOU SPILL SOMETHING ON YOUR COMPUTER: This includes spilling a drink on your computer, dropping it in a puddle, even having it rained on. The first thing to remember is NOT TO TURN IT ON. If it is on, turn it off IMMEDIATELY. You don’t want to restart the computer until it is completely dry. If it’s a desktop, it’s usually easier to substitute a new, dry keyboard. If it’s a laptop, it will require disassembly, drying, cleaning with alcohol and even blow-drying. There are even special “bags” on the market these days that are sold to wick the moisture from hard drives if they get wet. Since laptops (like many Apple computers) can be like a Chinese puzzle to disassemble and reassemble, better leave it to the professionals. If you’re lucky, once everything is dry, it’ll work again. If not, it could mean that you’ve allowed liquid to bridge the contacts on the main or other circuit boards, drives or the like, shorting the board. Depending on the circuit, repair could be prohibitively expensive, replacement a much less expensive option.

COMPUTER TIP #26: ALWAYS TRAVEL WITH YOUR LAPTOP IN ITS CASE. This point is related to the one immediately above (what to do if your computer gets wet). Laptops especially must be kept dry. They’re much more moisture sensitive than you might think. Even the slightest amount of water on the keyboard or through the air vents on the side or the back of the machine can possibly cause shorts and even permanent damage to the machine. Don’t use the laptop in the rain. Don’t take the computer, even to your car, if it’s raining, without enclosing it in a waterproof case or bag. You’re taking a big risk. (Also, don’t throw the laptop on any hard surface, like the floor of a car, as it could damage the drive head. But that’s a separate subject.)
ALSO, if you’re traveling by airplane, check the search laws (click HERE) regarding laptops and other electronic devices (smart phones, ipads, etc.), which basically allow officers some “reasonable” (though undefined) degree of suspicion to justify examining your laptop (with specialized software) not only for terrorist tendencies (e.g. documents, even a newspaper, written in farsi; your search history), but also anything else that they may find, such as kiddie or adult porn, tax or business records, photos, diaries, drug dealing or the like, in order to provide them with a “digital portrait” of you and your activities. Last year (2010), a total of 6,671 travelers, 2,995 of them American citizens had their electronic gear searched. And they can keep your laptop, sometimes for weeks. Moreover, you can expect this treatment each time you travel afterwards. Traveling with the data on your USB drive may not solve the problem - they search that, too. Perhaps safest is to retrieve your data from the cloud, but remember to professionally erase the data and history before returning to the U.S.

COMPUTER TIP #27: REMEMBER WHERE YOU SAVE FILES IF YOU WANT TO FIND THEM AGAIN: Due to the lack of even basic computer education about file management (i.e. “your computer is basically like a large electronic file cabinet”) on the part of first-time computer users, it’s not surprising that even though users know that they have to “save” their work in order to print, edit or send it later, they still have lots of trouble finding files or downloads when they decide to look for them. Personally, if I’m going to download a file, particularly if I’m going to look at it once then discard it, I usually select the ‘Save To” option as the “Desktop”. It’s easy, as Desktop is the very first location on the drop-down menu enabled by the arrow at the right of the “Save In” window. That way, it’ll be there as soon as I get out of the program or the Web and I know it will be right there, somewhere on my Desktop. I can look it it, send or print it, the drag it to the Recycle Bin and dump it. Same for text files and the like: If you save it to the Desktop, you’ll always know where to look for it, and you can always drop-and-drag it to My Documents or some other destination.

COMPUTER TIP #28: DON’T FORGET ABOUT YOUR CREDIT CARD WARRANTY: Just because your computer equipment, camera or other hardware dies just after the manufacturer’s warranty expires doesn’t always mean that you’re completely out of luck. Don’t forget to check your credit card warranty provisions. In many cases, if you purchased the product with a credit card, you automatically get the added benefit of an extended warranty, in some cases double the original warranty. Also, many jurisdictions (Maine, for example) have “implied” warranties that may take precedence over the manufacturer’s warranty, stating that the article must be usable for the purpose intended for the length of time most such articles are useful. Check HERE for a list of consumer protection offices.

COMPUTER TIP #29: WHY CAN’T I INSTALL MY DOWNLOADED PROGRAM? Lately, I hear this a lot. When you attempt to install a downloaded program or open a downloaded file, you get a message like “access denied” or “virus risk” or “malware infection”. It’s probably your anti-virus or anti-spyware program, blocking the file or program. More and more, to be on the safe side, anti-virus and anti-malware programs block downloads as “riskware” and don’t allow you to access them. Time was, you could disable the anti-virus spyware from your toolbar and opt to install. More often, nowadays, you have to either edit your program settings direcly or else do a complete uninstall of your anti-virus software to effect the install. Sorry. Or, if it’s not the anti-virus, if you right-click on the file to install and select “run as administrator” that may solve the problem as well.

COMPUTER TIP #30: DON’T FORGET TO DISABLE CELL PHONE APPS IF YOU’RE LEAVING THE COUNTRY: Traveling outside of the U.S. with your cell phone? BEWARE if you travel internationally with your cellphone! If you don’t turn off your data apps, like the radios on your Windows mobile devices, they will continue to download & update data, in addition to your high per-call roaming charges . Your bill may be a big surprise, easily topping $1000! There are ways around this. Verizon and Sprint (which use CDMA, not the GSM technology favored by Europe) will lend you a phone if you’ve been a subscriber for over 6 months. Or you can buy an inexpensive phone from Telestial or PlanetOmni for less than $50. You may be able to change your rate plan with your current carrier to account for your travel. You may also be able to obtain a SIM card for your phone (unless, of course, you have a carrier like Verizon, which doesn’t use such cards), but it won’t let you keep your own phone number. You can sign up for VoIP services from Skype or Boingo to reduce your costs. Finally, you can always use a calling-card, some of which have discounted rates for international calls. Just be sure to make plans ahead of your trip if you need to be connected from outside the country. Supposedly, the EU is working on eliminating these problems, scheduled to be installed by 2014.

COMPUTER TIP #31: WHAT TO DO IF YOUR HARDWARE WON’T INSTALL OR STOPS WORKING: First, completely uninstall the software for the device. Either go to the program list and see if it has an “Uninstall” feature or else go to Start>Control Panel>Add and Remove Programs (or Programs and Features if it’s Vista or Win7), then follow the instructions and reboot the computer. Then, reinstall the software for the device. If that doesn’t work, go to the website for the manufacturer (say, Linksys, if it’s a router or HP, if it’s the printer) and check to see if you’re using the latest software (it may be called “firmware”) if it’s for a hardware device. If all else fails, call the help desk for the manufacturer of the device. They should be trained to solve most issues and, besides, you’ve paid for their support when you purchased the device. Don’t want to bother with all of this, call a pro for on-site support.

COMPUTER TIP #32: DO I ALWAYS HAVE TO SHUT DOWN MY MONITOR OR PRINTER OR OTHER EQUIPMENT? Some of you may remember many years ago when we were instructed to start up our computers, first with the printer, then the monitor and, finally, the CPU, in order to avoid power surges to the computer when turning on the peripherals. Shutting off was the reverse order for the same reason. Of course, due to technological advances in equipment, this is no longer necessary. Similarly, there’s no need to turn off the LCD monitors, or even the inkjet printers, completely each time you shut down. They go into sleep mode or else use so little power that you could leave them on for a year and only consume a nickle worth of electricity and cause no damage to the equipment. I see people all the time shutting down their LCD monitors completely, for instance, even though it will put itself in standy mode automatically. It’s an unnecessary step. In the old days it did, in fact, pay to shut off the CRT monitors, since they did not shut down completely, using electricity and generating lots of heat. For more advice on how often to shut down your computer system, click on FAQs HERE.

COMPUTER TIP #33: WHAT DO THE WINDOWS ERROR MESSAGES MEAN? It’s inevitable that, after you’ve used a Windows computer for a while, you will encounter an error message. It’s also probable that the message will look like gibberish to you. Even if you Google the message number (yes, we pros do that all the time), the answer might still be incomprehensible to you, or you might not have the confidence to attempt the fix. In that case, call for professional computer help. However, a few guidelines may be helpful toward understanding the issue: (1) “Stop” messages means that Windows has literally stopped (as if you need Microsoft to tell you that!). They generally look like this: “STOP 0x0000000A.” The hexadecimal numbers may be in parenthesis, and if you’re lucky, it may give you a somewhat cryptic english message as well, e.g. “DEVICE_QUEUE_NOT_BUSY.” Since most of these messages deal with hardware issues, if you’ve just installed a hardware driver, try rolling it back, it may well solve the problem. Or, if you know how, remove the cover and check to be sure that all of the hardware cables are in securely. (2) System Error Codes, which are numbered from 0 through 15999, cover just about everything in the O/S. For example, “ERROR_REVISION_MISMATCH 1306(0x51A)” means that two revision levels of software are incompatible. A listing of these error codes and their meaning can be found HERE. Or Google them. This is difficult stuff, but at least now you know what the messages mean.

COMPUTER TIP #34: WHAT SHOULD I DO IF I’M NOT GOING TO USE MY COMPUTER FOR A WHILE? Unplug it. What’s “a while”? I’m talking if you’re going to be gone more than a week or so. If you’re taking a two week cruise, leaving Florida until next season or the like. Why? Computers are designed to be used. If you don’t use them for some period, but leave them plugged in, they may not work perfectly when you return. The hardware may require you to pull out cards or cables and re-seat them. More often, if you completely unplug the computer, these things tend to happen less.

COMPUTER TIP #35: IS THERE ANY WAY TO GET AROUND THOSE ANNOYING CELL PHONE MENUS? You know, when you call someone and you get a long menu even after hearing the answering machine message of the person you called. You already know what to do. Do you have to suffer through the menu every time? Not if you know the code to jump past it. At the moment the codes are as follows: For Verizon and Cingular, press * ; For Sprint, press 1; and for TMobile, press #.
