Porównanie komponentów laptopów i komputerów desktop Elementy komputerów desktop są standaryzowane. Zwykle maja określone współczynniki Kusztalów. Komponenty laptopów często są typowe dla producenta po to, aby uczynić je bardziej wydajnymi i kompaktowymi. Często nie można wykorzystać elementów wykonanych przez jednego producenta laptopa do naprawy laptopa innego producenta. Slide 22 – Compare Laptop Components and Desktop Components 6.3 Compare and contrast desktop and laptop components Desktop components tend to be standardized. They usually meet universal form factors. Laptop components are much more specialized than desktop components. This difference is because laptop manufacturers focus on refining laptop components to make them more efficient and compact. As a result, manufacturers design laptop components to follow their own specific form factors. Laptop components are proprietary, so you may not be able to use components made by one laptop manufacturer to repair a laptop made by another manufacturer. NOTE: Technicians may have to obtain certification for each laptop manufacturer that they support.   After completing this section, students will meet these objectives: Compare and contrast desktop and laptop motherboards. Compare and contrast desktop and laptop processors. Compare and contrast desktop and laptop power management. Compare and contrast desktop and laptop expansion capabilities.

Laptop motherboards vary by manufacturer and are proprietary. It is strongly recommended that you obtain a replacement motherboard from the manufacturer of the laptop.

Porównanie procesorów Slide 24 – Compare CPUs 6.3.2 Compare and contrast desktop and laptop processors The central processing unit (CPU), or processor, is the brain of the computer. The CPU interprets and processes instructions that are used to manipulate data. Laptop processors are designed to use less power and create less heat than desktop processors. As a result, laptop processors do not require cooling devices that are as large as those found in desktops. Laptop processors also use CPU throttling to modify the clock speed as needed to reduce power consumption and heat. This results in a slight decrease in performance. It also increases the lifespan of some components. These specially designed processors allow a laptop to operate for a longer period of time when using a battery power source. NOTE: Technicians should refer to the laptop manual for processors that can be used as replacement processors and for processor replacement instructions. Common Error: Lower voltage does not necessarily equal lower speed.

Porównanie opcji zasilania Slide 25 – Compare Power Options 6.3.3 Compare and contrast desktop and laptop power management Power management controls the flow of electricity to the components of a computer. Desktops are usually set up in a location where they remain plugged into a power source. Desktop power management distributes electricity from the source to the components of the desktop. There is also a small battery in the desktop that provides electricity to maintain the internal clock and BIOS settings when the desktop is powered off. When the laptop is plugged in, laptop power management sends electricity from the AC power source to the laptop components. When the laptop is unplugged, laptop power management takes electricity from the battery and sends it to the laptop components. There are two methods of power management: Advanced Power Management (APM) is an earlier version of power management. With APM, the BIOS was used to control the settings for power management. Advanced Configuration and Power Interface (ACPI) has replaced APM. ACPI offers additional power management features. With ACPI, the operating system controls power management.   Laptop Power Options Desktop Power Options

Porównanie możliwości rozbudowy Slide 26 – Compare Expansion Capabilities 6.3.4 Compare and contrast desktop and laptop expansion capabilities Many expansion devices can be used with both laptops and desktops – external drives, modems, network cards, wireless adapters, printers, and other peripherals. Expansion devices are attached to laptops and desktops differently. A desktop attaches these devices with serial, parallel, USB, and FireWire ports. A laptop attaches these devices with the same ports and PC Cards. USB and FireWire standards make it possible to connect and remove external components without the need to power off the system. Desktops have internal bays that support 5.25" and 3.5" drives. Additionally, there is space to install other permanent expansion drives. Laptops have limited space so the expansion bays on laptops are designed to allow different types of drives to fit into the same bay. Drives are hot-swappable and are inserted or removed as needed.

Porównanie możliwości rozbudowy Slide 27 – Compare Expansion Capabilities 6.3.4 Compare and contrast desktop and laptop expansion capabilities Laptops use the PC Card slot to add functionality. The PC Card slot uses an open standard interface to connect to peripheral devices using the CardBus standard. PC Cards follow the PCMCIA standard. They come in three types: Type I, Type II, and Type III. Each type of PC Card is different in size and can attach to different devices. A newer type of PC Card is called the PC ExpressCard. The PC ExpressCard has 34-pin and 54-pin configurations. Suppose you need to purchase a wireless NIC for a laptop. Which type of PC Card would you select?   Teaching Strategy: A USB wireless NIC could be used with a laptop or desktop. A PC card wireless NIC could be used with any laptop that has the appropriate PC card socket. An ExpressCard wireless NIC could be used with any laptop that has the appropriate ExpressCard socket. Some laptops use an internal wireless NIC that fits in a Mini-PCI slot. Student Activity: The student course content includes the worksheet, 6.3.4 Laptop Expansion. To complete this worksheet, students will answer questions regarding the details of laptop expansion.

Dodając komponenty zwykle używamy techniki Plug and Play, jednak czasem może być potrzeba instalacji dodatkowego sterownika. Przestrzegaj zasad bezpiecznego usuwania sprzętu. Slide 28 – Configure Laptops 6.4 Explain how to configure laptops To allow applications and processes to run smoothly, it may be necessary to configure and allocate system resources, install additional components and plug-ins, or change environmental settings to match software requirements. Adding external components is usually accomplished through the use of Plug and Play, but occasionally driver installation and additional configuration may be required. Proper configuration of the power settings will help you get the maximum performance from a laptop, such as increasing the length of time the laptop can be used on battery power. A laptop can be customized for specific purposes by adding external components. For example, a second hard drive can be installed in a laptop to provide additional storage capacity. Components need to be carefully inserted or connected to bays, connectors, and proprietary expansion areas to avoid damage to the equipment. It is important to follow safe removal procedures when disconnecting hot-swappable and non-hot-swappable devices.   After completing this section, students will meet these objectives: Describe how to configure power settings. Describe the safe installation and removal of laptop components.

W Windows XP jest to „Stan hibernacji”. S5 Komputer jest wyłączony. Slide 29 – Configure Laptop Power Settings 6.4.1 Describe how to configure power settings Proper configuration of the power settings will help you get the maximum performance from a laptop, such as increasing the length of time the laptop can be used on battery power. The Advanced Configuration and Power Interface (ACPI) standards create a bridge between the hardware and OS and allow technicians to create power management schemes to get the best performance from the computer. The ACPI standards can be applicable to most computers, but they are particularly important when managing power in laptops. NOTE: There is no standard name for each power management state. Manufacturers may use different names for the same state. 

Sprawdzanie opcji ACPI w BIOSie Kroki do sprawdzania opcji ACPI w BIOSie: Wejdź do BIOS, naciskając odpowiedni klawisz lub kombinację klawiszy podczas uruchamiania komputera. Zwykle jest to klawisz Delete lub F2, ale istnieje jeszcze kilka innych opcji. Znajdź lub wpisz "Power Management Settings" z menu. Użyj odpowiednich klawiszy w wyboru trybu ACPI. Zapisz i wyjdź z BIOS. Slide 30 – Checking the ACPI Settings in the BIOS 6.4.1 Describe how to configure power settings Technicians frequently are required to configure power settings by changing the settings found in BIOS. Configuring power settings in BIOS affects the following conditions: System states Battery and AC modes Thermal management CPU PCI bus power management NOTE: When working in Windows XP, the ACPI power management mode must be enabled in BIOS to allow the OS to configure all of the power management states.  Here are the steps to check the ACPI settings in the BIOS: Enter BIOS setup by pressing the appropriate key or key combination while the computer is booting. Typically this is the Delete key or the F2 key, but there are several other options. Locate and enter the “Power Management settings” menu item. Use the appropriate keys to enable ACPI mode. Save and Exit BIOS setup. NOTE: These steps are common to most laptops and should be used only as a guideline. Be sure to check your laptop manual for specific configuration settings.

The Power Options displays only the options that can be controlled.  NOTE: Power Options will automatically detect devices that may be unique to your computer. Therefore the Power Options windows may vary by the hardware that is detected.  To configure your power settings, click: Start > Control Panel > Power Options Power Schemes are a collection of settings that manage the power usage of the computer. Both the hard drive and the display consume large amounts of power. They can be configured under the Power Schemes tab.  When you open Power Options, you will notice that Windows XP has preset power schemes. These are the default settings and were created when Windows XP was installed. You can use the default Power Schemes or create customized schemes that are based on specific work requirements. If you do not want to completely shut down the laptop, you have two options – Standby and Hibernate. Standby – Documents and applications are saved in RAM, allowing the computer to power on quickly Hibernate – Documents and applications are saved to a temporary file on the hard drive, and will take a little longer than Standby to power on. In Windows XP, you can set the low battery warnings. There are two levels: Low Battery Alarm and Critical Battery Alarm. The Low Battery Alarm will warn you that the battery is low. The Critical Battery Alarm will initiate a forced standby, hibernate, or shutdown. Student Activity: The student course content includes the worksheet, 6.4.1 ACPI Standards. To complete this worksheet, students will write in the appropriate ACPI standard to match the power management state description.

Standardy telefonii komórkowej Zastosowanie Short Message Service (SMS) Multimedia Message Service (MMS) Przełączanie pakietów Wysyłanie wiadomości tekstowych Wysyłanie obrazów i dźwięków Used for accessing the Internet Slide 33 – Mobile Phone Standards 6.5 Compare the different mobile phone standards When people began to use cell phones, there were few industry-wide standards applying to cell phone technology. Without standards, it was difficult and expensive to make calls to people that were on another network. Today, cell phone providers use industry standards, which make it easier to use cell phones to make calls.  When the industry started, most cell phone standards were analog. Today, cell phone standards are mostly digital.  NOTE: Cell phone standards have not been adopted uniformly around the world. Some cell phones are capable of using multiple standards, whereas others can use only one standard. As a result, some cell phones can operate in many countries and other cell phones can only be used locally.  The student course content details the five generations of cell phone standards. New technologies that add multimedia and networking functionality can be bundled with cell phone standards. This table lists common technologies that may be added to the cell phone bundle of services. Most cell phone providers will charge extra for adding these features.

1. Zbierz dane od klienta Dane klienta Konfiguracja komputera Nazwa firmy, nazwa osoby, dane kontaktowe Konfiguracja komputera System operacyjny, zainstalowane aktualizacje, środowisko sieciowe Informację należy zbierać na zleceniu Opis problemów Pytania otwarte Co było wykonywane kiedy problem się pojawił? Pytania zamknięte Czy laptop był wtedy podłączony do sieci? Slide 62 – 1. Gather Data from the Customer 5.7.1 Review the troubleshooting process The first Krok in the troubleshooting process is to gather data from the customer. This Krok allows the technician to evaluate the situation. The technician must organize the information about the customer and the reported problem. Often a work order is used to collect this information. There are two types of questions you can ask: open-ended questions and close-ended questions. Open-ended questions cannot be answered with "yes" or "no" answers. The purpose of open-ended questions is to allow the customer to describe the problem. Close-ended questions can usually be answered with "yes" or "no" answers. This type of question can help a technician focus in on an error and locate the exact problem once a potential solution is being tested. Examples of open-ended questions: What problems are you experiencing with your computer or network? What software has been installed on your computer recently? What were you doing when the problem was identified? What operating system do you have installed on your computer? What updates or patches have been installed on your computer? Examples of closed-ended questions: Has anyone else used your computer recently? Does the computer boot up successfully? Have you changed your password recently? Have you received any error messages on your computer? Are you currently logged into the network? When a customer is not able to accurately describe the problem, there are other ways to evaluate the situation in subsequent steps in the troubleshooting process.

2. Sprawdź oczywiste kwestie Sprawdź najbardziej typowe problemy: Nieprawidłowe połączenia Sprawdź Managera urządzeń, sprawdź dopasowanie komponentów. Problemy z zasilaniem Sprawdź diody i źródło zasilania. Problemy z WiFi Sprawdź połączenia sieciowe i siłę sygnału. Problemy z dźwiękiem Sprawdź ustawiania w systemie operacyjnym. Slide 39 – 2. Verify the Obvious Issues 6.7.1 Review the troubleshooting process Examine the most obvious causes of a problem. Loose or improper connections Sometimes a problem can be solved by something as simple as finding a loose or improper connection. Check the Device Manager for information. A component may need to be removed and reinserted properly. Power issues Check the battery LED and the AC power LED. Is the correct AC adapter being used? Is the battery or the AC adapter damaged? Is the wall outlet supplying power? Wireless network issues Check wireless network LED and Ethernet LED. Check Network Connections in Control Panel. Check wireless signal strength. Sound and audio issues Function (Fn) keys can cause error messages if used incorrectly and may affect audio and video. Fn keys control these features on most laptops; volume, mute, LCD brightness, and external monitor. Stylus issues The stylus or digitizer controls the position of the screen cursor by responding to the pressure of a stylus on the PDA screen. The stylus may need to be re-calibrated or re-aligned. Clean the screen. Check the settings for the stylus.

3. Spróbuj najpierw najszybszych rozwiązań Szybkie rozwiązana oszczędzą czas i pieniądze: Uruchom ponownie komputer. Verify BIOS settings. Usuń lub odłącz niepotrzebne urządzenia peryferyjne. Użyj opcji Ostatnia znana dobra konfiguracja. Slide 40 – 3. Try Quick Solutions First 6.7.1 Review the troubleshooting process If you identify simple problems and solutions early, you can save significant amounts of time for the technician and money for the client. Here are some quick solutions: Reboot the computer. Many problems can be resolved by rebooting the computer. Verify BIOS settings. BIOS settings may have been altered by mistake. BIOS can be reset to the default setting to undo any changes made by the user. Remove or unplug unnecessary peripherals. Removing a peripheral eliminates a variable that has the potential to cause a problem. If the problem is eliminated by removing peripherals, the technician can observe as peripherals are added back to the system. The last peripheral added before a problem recurs is likely to be the cause of the problem and may need to be checked for the correct system resource assignment. Use the Last Known Good Configuration option. If the laptop has a problem caused from adding a new application, driver, or device, Last Known Good Configuration will allow you to boot the computer with the same settings that you had prior to the problem.

Close with the Customer 5.7.1 Review the troubleshooting process When you are confident that the problem has been resolved, the next Krok is to close with the customer. The technician must completely document the customer contact information, problem description, and steps to resolve the issue in the work order. Explain to the customer each Krok that you took to solve the problem. The customer needs to understand what caused the problem in order to avoid similar kinds of problems in the future. Turn on the computer and let the customer verify that the problem has been solved. Finally, have the customer reboot the system and check for any problems. Complete all documentation. Make sure you fill out all internal documentation, such as sales orders, time logs, and receipts. A work order should be completed and the repair journal should be updated. You can use the notes from the journal for future reference and to build a knowledge database.
