Managing and troubleshooting pcs fourth edition pdf download

You look at the customers request and determine that it should be possible with your product, though you dont have any record of anyone actually doing that. How do you help the customer? Depending on the support boundaries for your product, you can tell them about or help them along with the additive method. To use a different example, lets suppose a customer needs help composing a complex formula in a spreadsheet you support.

An additive approach might be to break down the formula into smaller pieces, trying and testing each of them in its own cell on the spreadsheet. Then, add one part at a time into the cell containing the full formula.

Since we only change or add one thing at a time, if we run into trouble, we know that the problem is in the last step we took. Check for Success As you are executing the most likely approach, ask yourself:. Did the proposed solution solve the problem? Is there any further testing we need and can do to determine that the problem is indeed fixed? Does it work in the customers usual working environment? If you AND the customer are satisfied that the problem has been resolved, move on to the next step.

If the printer refuses to print a self-test, then you have obviously tested the printer and found it to be the problem. If you have determined the problem is a printer driver, try to see if the printer will print with an updated driver, or if the computer will print to another printer. You will not always be able to test each diagnosis, but you should always try.

What if the Solution Does not Work? If another very likely solution exists, go ahead and try it. After you have exhausted all avenues, you may need to contact a mentor.

Otherwise, the engineer should be ever ready to return to Gathering Information and possibly redefining the problem. Note: Again, sometimes there is more than one problem in a given system, so the fact that you found a problem doesnt necessarily mean that you found THE problem. Testing lets you know. You may have to perform the previous steps until a resolution is achieved. Each cycle through should leave the previous modifications in place. This will ensure that a combination of conflicts is caught.

Being systematic will result in success while random trial-and-error usually results in frustration. Check for success pitfall: If the first strategy does not resolve the problem, the engineer may fall back on hit or miss problem solving.

Remember to ask yourself why you are trying the next strategy. If you arent clear why, then examine what you know more closely, gather more facts or consult your resources. There is always a best strategy, but sometimes you need to gather more information before determining the best strategy under the current circumstances.

Tie up Loose Ends If you have made it to this step, you have most likely resolved the issue. Now you must explain to the customer what was discovered, whether you can put the machine back exactly as it was before the call, and how to avoid the issue in the future.

The engineer needs to make sure the issue is really closed. Are there any loose ends that need to be tied-up before releasing the phone connection? Here are some ideas to consider before hanging up the phone:.

Is the customer satisfied? Does the operating environment, or customer-specific settings need to be restored? Was the fix substantial enough that the customer should not have to call back on the same issue?

Was the incident satisfactorily resolved? Is follow-up required? This stage often takes some diplomacy, especially if the resolution requires you to disable a program or utility the customer was using prior to the call.

Always give the customer the option to restore the machine exactly as it was prior to the call. Explain the upside and the downside of the restoration. More often, you fix a system issue that was just exposed by the application. This is a winwin for the customer and us. Fix If the problem is an easily replaceable part, replace it. If the problem is a conflicting extension, we can remove the offending extension. If the customer was applying incorrect procedure, we can show the customer the correct way to do the task.

Usually, the fixable problem is obvious to everyone. It is also very satisfying to the engineer, since the customer is almost always thrilled that you were able to help them. You cant always make things work exactly the way the customer wants. Sometimes you need to find another way for the customer to proceed to the desired result.

This is called a workaround. Up against a limit to the number of characters in a formula? Try breaking the formula up across several cells, or using Boolean notation to reduce the number of characters needed.

HTML doesnt recognize multiple spaces? Try using a non-breaking space character, or using tables to space your columns. Finding a creative workaround for the customer is also a rewarding part of working with customers.

The B word Sometimes products will not do what the customer wants it to do. Be very careful of calling something a bug, however. Programmers and customers both use the word, but they do not mean the same things by it. Heres a handy table to show you the differences: Programmers. There is a specification written that describes in great detail what this program is supposed to do. If the program doesnt do what the specification says it will do, then that is a bug.

I have in mind something that I want this program to do. If this program will not do that, then that is a bug. Obviously, with such a chasm between the technical and common meanings of the word, it is best to avoid calling something a bug until it has been checked against the specification and added to the bug list. This avoids having your name quoted in the trade journals Soand-so at Microsoft admitted this bug to our reporter on a call to tech support Yes, it has happened.

Thank the customer for pointing out this problem, or thank them for their suggestion. Still, sometimes we just get to the point where we cant help the customer any further.

Sometimes there are bugs in the program. This is when your customer service skills come in to play. And, actually, getting to this point is a victory in its own right. You have attacked and isolated a technical problem, and have it defined to the point where it can be dealt with. A Final Note The very first time you encounter a problem is when the most learning takes place. Subsequent times, the troubleshooter applies past knowledge, whether consciously or not, thus building good knowledge upon good, or bad knowledge upon bad.

The most learning takes place on the first shot, because that is when the troubleshooters knowledge goes from nothing to something. Later, the knowledge may go from something to something else, but never again will it increase as much as that first time. A reflective, well-researched approach to solving the problem the first time will ultimately pay off in savings when the problem is revisited.

What is linear and logical troubleshooting? List down the 2 methods for linear and logical troubleshooting. What is additive technique? What is subtractive technique? What are the pitfalls of using subtractive technique? Silver Bullet Troubleshooting When talking about Linear Logical Troubleshooting, you should also understand the opposite type of troubleshooting, often called Silver Bullet Troubleshooting. Using Silver Bullet, we take single shots at possible right answers.

If we guess correctly, the cause is identified in almost no time. If we guess incorrectly, we are no closer to the correct answer, and may have lost the confidence of the customer by followin g the wrong path.

Remember, using Linear Logical means that every answer moves us closer to the cause and the solution. Silver Bullet puts all the emphasis on a Yes and we gain nothing from a No. Points to Remember. Linear Logical Troubleshooting is a progressive method to eliminate possible causes until the true issue is isolated.

Linear Logical Troubleshooting uses simple, closed-ended questions that narrow the focus of investigation regardless of the answer. The Subtractive method of troubleshooting is a method in which the Support Engineer makes a mental list of all of the components that could be involved in creating the problem.

Then methodically eliminates the components as the culprit until a solution is found. Silver Bullet Troubleshooting is the method of trying possible solutions without doing the proper background investigation. Silver Bullet Troubleshooting often wastes time with wrong solutions and reduces customer confidence. What is Silver Bullet Troubleshooting? Information Gathering Gathering information is an important and ongoing part of Linear Logical Troubleshooting.

It allows the Support Professional to focus the investigation simply by asking some standard questions. At times the customer may feel the questions are pointless, but facts and information are never pointless. Inform the customer that gathering information allows us to see the entire picture. Example: I have several questions to ask in order to be thorough in analyzing all the facts before I start drawing conclusions. Limiting the Field When a customer calls saying they have a problem, the list of possible causes can be endless.

The Support Professional needs to start asking questions to focus the investigation on a particular area of the computer. The first thing the Support Professional can do is have the issue explained completely.

Do this by asking open-ended questions that allows the customer to speak freely on their situation. Example: So what seems to be the trouble today? Once the situation has been explained, the Support Professional should start gathering specific information about the customers system.

These are a standard set of questions that allow the Support Professional to understand the customers environment. Much of the information might feel unneeded or even a waste of time, but this basic computer information prevents the investigation from taking a wrong turn or making a wrong assumption. Some of the questions you should ask are:. Who manufactured your computer? Does it have a brand name or was it built by a local shop?

What version of Windows are you running? Not sure, lets take a look at the system properties to find out for sure? How much memory and what type of processor are you running? System information can help us with this as well as an original receipt for the computer. What version of the software in question are you running?

Can we go to the Help or About menu and find out? Example: So right before the computer locks, what is it doing and what is being displayed on the screen? Each answer and each explanation will start to limit our field of investigation.

If the issue only started after certain software was installed, we have limited the field to what was changed during the installation process. When the Support Professional has formed a picture of the customers issue, then it is time to start using closed-ended questions.

This allows us to pin down the specifics of the issue and specifics of our field of investigation. Not only do we use closed-ended questions to gather more information, but also to test assumptions that we are starting to make about the issue.

Example: Please tell me the exact error message, word for word. You can even test ideas. If you boot the computer without a CD in the drive, does it have any problems? In summary, when gathering information, we always start with the open-ended questions that allow the customer to explain why they called Microsoft Support. We then concentrate on the facts about the computer system and the software installed.

Our picture of the customers situation will now allow us to ask directed open-ended questions. We are firming up our understanding of the issue and starting to focus on particular areas of the computer.

Finally, we ask closed-ended questions that either fully explain the situation, or test our understanding. Forming a picture of both the issue and the computer system is vital to Linear Logical Troubleshooting.

Emphasize to the customer that gathering information on their computer system allows us to do the best job possible. Remember to ask open-ended questions and allow the customer the opportunity to explain the issue up front. Ask closed-ended questions to gather specifics about the issue and to test assumptions made during the information gathering stage. Method 1: Clean Install A clean installation removes all data from the hard disk by repartitioning and reformatting the hard disk and reinstalling the operating system and programs to an empty clean hard disk.

This is typically done when a new hard disk is installed on a computer. Method 4: Install Windows XP to a new folder parallel installation This method is used to install Windows XP to a new folder parallel installation to either run two operating systems, or to access, repair, or retrieve data from a damaged disk.

Method 5: Perform a multiple boot operation not supported by iYogi This method is used to install Windows XP as a separate operating system on the computer. Using this method more than one operating system can be installed on a computer and One can also select which operating system would start by default every time that you start your computer.

What is the difference between clean install and installing Windows XP on a new hard drive? What is parallel installation and why is it required? What is multi boot operation? Hard Disk Technologies A hard disk drive hard disk, hard drive, HDD is a non-volatile storage device for digital data.

It features one or more rotating rigid platters on a motor-driven spindle within a metal case. Serial ATA is a serial link -- a single cable with a minimum of four wires creates a point -to-point connection between devices.

One of the main design advantages of Serial ATA is that the thinner serial cables facilitate more efficient airflow inside a form factor and also allow for smaller chassis designs. SCSI: Short for small computer system interface, SCSI interfaces provide for faster data transmission rates up to 80 megabytes per second than standard serial and parallel ports.

Disk Partitions Disk partitioning is the act of dividing a hard disk drive into multiple virtual hard disk drives, referred to as partitions, in order to treat a single physical disk drive as if it were multiple disks.

A disk partition is a logical section of a hard disk on which the computer may write data. Partitions offer a way to divide the space on a single physical hard disk into multiple areas, each of which is treated as a different disk within Windows.

Types of hard drive partitions:. Primary: A primary partition is one that can be used as the system partition. If the disk does not contain a system partition, you can configure the entire disk as a single, extended partition. Extended: An extended partition provides a way to bypass the four primary partition limits. One cannot format an extended partition with any file system. Rather, extended partitions serve as a shell in which one can create any number of logical partitions. Logical: A Logical Partition LPAR is the division of a computer's processor, memory, and storage into multiple sets of resources so that each set of resources can be operated independently with its own operating system instance and application s.

Apart from the above three partitions, there are two more partitions that are discussed underneath:. Boot Partition: The boot partition is the disk partition that contains the Windows operating system files and its support files, but not any files responsible for booting. File System A file system is a method of storing and organizing computer fil es and their data. Essentially, it organizes these files into a database for the storage, organization, manipulation, and retrieval by the computer's operating system.

There is a copy of the File Allocation Table for backup purposes. If possible, the system will use the copy of the FAT if the original table becomes corrupt. There are 3 versions of FAT. It can be used on both basic and dynamic disks, and provides many features and benefits that are not found in other file systems.

The benefits of NTFS include:. Disk quotas: Provides the ability to control how much disk space each user can have. What are the three versions of FAT and where are they used? What are the benefits of using NTFS? If you miss the prompt it only appears for a few seconds , restart your computer to try again. Windows XP Setup begins. During this portion of setup, your mouse will not work, so you must use the keyboard. Then press F8. Once you click F8 to accept the license agreement it will display a new page which enables you to select the hard disk drive on which Windows XP will be installed.

Once you complete this step, all data on your hard disk drive will be removed and cannot be recovered. It is extremely important that you have a recent backup copy of your files before continuing.

When you have a backup copy, press D, and then press L when prompted. This deletes your existing data. You can choose other file systems also. Windows XP erases your hard disk drive using a process called formatting and then copies the setup files. Windows XP restarts and then continues with the installation process. From this point forward, you can use your mouse.

Eventually, the Regional and Language Options page appears. Click Next to accept the default settings. If you are multilingual or prefer a language other than English, you can change language settings after setup is complete.

When the Monitor Settings dialog box appears, click OK. The final stage of setup begins. On the Welcome to Microsoft Windows page, click Next.

Windows XP will then check if you are connected to the Internet. If you are connected to the Internet, select the choice that describes your network connection. If youre not sure, accept the default selection, and click Next. If you use dial-up Internet access, or if Windows XP cannot connect to the Internet, you can connect to the Internet after setup is complete. In such scenario click Skip.

If you are connected to the Internet, click Yes, and then click Next. If you are not yet connected to the Internet, click No, after the setup is complete, Windows XP will automatically remind you to activate and register your copy of Windows XP. Remember if you are connected to Internet than setup will prompt you to register the windows, if you choose to skip as Internet connection is not working it directly take you to Users page. On the next screen Who will use this computer? After typing the names, Then click Next.

To add users after setup is complete or to specify a password to keep your account secured. On the Thank you! Windows XP setup is complete. You can log on by clicking your name on the logon screen. After the final phase, the system is rebooted:. Collecting Information- As Setup collects information about your system, you can do the following: o Specify an upgrade or a clean installation. Dynamic Update- Dynamic update, a new feature in Windows XP, connects to the Microsoft Windows Update Web site and downloads updated setup files, and critical bug fixes.

Critical security fixes may also be included, thereby enhancing the Setup experience. Dynamic update requires that your computer have the following: o Modem o ISP connection o Correct versions of wininet.

Provides you the option of specifying the partition on which to install Windows. Setup can also format partitions. Restarts your computer.

Which setup process phase prompts you to join a workgroup or domain? Which setup process phase allows you to install networking components? Which setup process phase allows you to customize the keyboard? It is used to enforce the Windows End User License Agreement by preventing or hampering the use of the operating system after a specific period of time until it is verified as genuine by Microsoft.

Internet: If you select activate and you have an active Internet connection, communication to the activation server occurs through secure HTTP. Modem: If an active Internet connection is not found or if activation over the Internet fails, the activation process searches for a modem. For telephone activation, the wizard presents a digit activation code that must be read to a Customer Service Representative.

A digit confirmation code from the Customer Service Representative must be entered back into the PC. The telephone activation screens also provide the option to change the product key for the system. If you used the same product key on several installs, you can correct it here. Upgrade Installation Upgrading vs. Clean Installation Upgrading During an upgrade, existing user settings are retained, as well as installed applications.

If you perform a clean installation, the operating system files are installed in a new folder, and you must reinstall all of your applications and reset user preferences, such as, desktop and application settings. Other cases where you will need to perform a clean reinstall are:. No operating system is installed on the computer The installed operating system does not support an upgrade to Windows XP. The computer has more than one partition and needs to support a multiple-boot configuration using Windows XP and the current operating system.

A clean installation is preferred. Prepare for careers in a world shaped increasingly by the powers of text, imagination, and tale. Vistas, 6th Edition.
