  2. Objectives • Understand and troubleshoot power management • Understand and troubleshoot I/O devices Guide to MCDST 70-271

  3. Power Management • Advanced Configuration and Power Interface (ACPI) • Extends battery life by powering down unused devices • Can control the system using soft power switches • Makes PC cards able to be hot-swapped and notebooks to be hot-docked Guide to MCDST 70-271

  4. Power Management (continued) Guide to MCDST 70-271

  5. Power Options • Applet is used to set system’s power-saving and battery management features • Typical tabs found in dialog box • Power Schemes • Alarms (notebook only) • Power Meter (notebook only) • Advanced • Hibernate • UPS Guide to MCDST 70-271

  6. Power Options (continued) Guide to MCDST 70-271

  7. Power Options (continued) Guide to MCDST 70-271

  8. Power Options (continued) Guide to MCDST 70-271

  9. Standby Versus Hibernate • Standby • Mode in which system goes into a lower power consumption mode • System can quickly return from Standby mode to fully operational mode in a few seconds • Hibernation mode • State of system is saved to temporary data file on hard drive and computer is fully powered off Guide to MCDST 70-271

  10. Troubleshooting Power Management Issues • ACPI-related problems • The system will not shut down • Standby and Hibernate modes are not available • Devices malfunction after restoring from standby or hibernation • The system is unable to resume from standby or hibernation • The monitor will not power back on after being powered off by ACPI Guide to MCDST 70-271

  11. Troubleshooting Power Management Issues (continued) • To troubleshoot ACPI problems: • Verify that computer hardware supports ACPI • Verify that ACPI is enabled via the computer’s BIOS • If necessary, enable ACPI through the computer’s BIOS • If necessary, update the BIOS on the computer Guide to MCDST 70-271

  12. Troubleshooting Power Management Issues (continued) • To troubleshoot ACPI problems (continued): • Verify that all device drivers are updated • Verify that latest service pack for Windows XP is installed • Verify that you are not using the generic VGA driver • If all other troubleshooting steps fail, attempt an upgrade or clean/new installation of Windows XP Guide to MCDST 70-271

  13. Managing I/O Devices • I/O device • Any device that is used to send input into the computer or produce output from the computer • Can be connected to a computer through • Serial, parallel • USB • IEEE 1394 (Firewire) • IR/IrDA (infrared) • RF/WiFi/wireless Guide to MCDST 70-271

  14. Installing Device Drivers via Add Hardware • Add Hardware applet • Used to install DVD players, CD players, tape devices, scanners, modems • Once a device is installed it can be configured and managed through Device Manager Guide to MCDST 70-271

  15. The System Applet Tabs • General tab • Displays operating system version, service pack level, registered username • Computer Name tab • Used to join a domain/workgroup and change the computer name Guide to MCDST 70-271

  18. The System Applet Tabs (continued) Guide to MCDST 70-271

  19. The System Applet Tabs (continued) • Automatic Updates Tab • Manages how Windows Update downloadable packages are handled • Remote tab • Enables, disables, and configures Remote Assistance and Remote Desktop Guide to MCDST 70-271

  20. The System Applet Tabs (continued) Guide to MCDST 70-271

  21. The System Applet Tabs (continued) Guide to MCDST 70-271

  22. The System Applet Configuration Options • Driver signing • Identifies drivers that have passed Microsoft Windows Hardware Quality Lab evaluation and tests • Options presented by Driver Signing Options dialog box • Ignore • Warn • Block Guide to MCDST 70-271

  23. Device Manager • Used to verify that a device is working properly • Lists all installed and known devices and indicates their status • Yellow exclamation point or a stop sign over a device’s icon indicates problems or conflicts Guide to MCDST 70-271

  24. Device Manager (continued) • A device’s Properties dialog box will have at least two standard tabs: • General: access type, manufacturer, and location settings • Driver: change driver settings or install or upgrade device-related drivers • Resources tab displays device’s resource settings Guide to MCDST 70-271

  25. Device Manager (continued) Guide to MCDST 70-271

  26. Device Manager (continued) Guide to MCDST 70-271

  27. Device Manager (continued) • Four main areas of hardware resource conflict • IRQ • I/O port • DMA (Direct Memory Access) • Memory Guide to MCDST 70-271

  28. Hardware Profiles • A collection of custom settings specific to a particular situation • Most often used on portable computers for which hardware configurations change often • Can be employed whenever there will be a hardware change between bootups Guide to MCDST 70-271

  29. Troubleshooting I/O Devices • Problem/solution combos that may assist in resolving problems • Out-of-date BIOS or firmware • Update using tools from the vendor’s Web site • Damaged connection cable • Replace the cable • Incorrect connection cable • Use the correct cable Guide to MCDST 70-271

  30. Troubleshooting I/O Devices (continued) • Problem/solution combos that may assist in resolving problems • Wrong hub type • Use the correct hub for the device connection type • Hub does not provide enough in-line power • Disconnect other devices or add direct power to device Guide to MCDST 70-271

  31. Summary • Windows XP supports both ACPI and APM standards • Power management must be an enabled feature of the installed hardware in order to function • Power Options applet is used to manage power issues Guide to MCDST 70-271

  32. Summary (continued) • Troubleshooting ACPI issues involves verifying that device drivers are updated and the ACPI features of devices are turned • Windows XP supports a broad range of I/O devices • Proper driver management is a key issue in troubleshooting devices Guide to MCDST 70-271
