Power Management Setup Option

This option displays items that let you control the system power management. Operating systems take care of much of the power management. This mainboard supports ACPI (advanced configuration and power interface). The system has various power saving modes including powering down the hard disk, turning off the video, suspending to RAM, and a software power down that allows the system to be automatically resumed by certain events.

Power Management Timeouts

The power-saving modes can be controlled by timeouts. If the system is inactive for a time, the timeouts begin counting. If the inactivity continues so that the timeout period elapses, the system enters a power-saving mode. If any item in the list of Reload Global Timer Events is Enabled, then any activity on that item will reset the timeout counters to zero.

Wake Up Calls

If the system is suspended, or has been powered down by software, it can be resumed by a wake up call that is generated by incoming traffic to a modem, a LAN card, a PCI card, or a fixed alarm on the system realtime clock.

ACPI Suspend Type Default: S1 (POS)

Use this item to define how your system suspends. In the default, S1(POS), the suspend mode is equivalent to a software power down. If you select S3 (STR), the suspend mode is a suspend to RAM – the system shuts down with the exception of a refresh current to the system memory.

Power Management Default: Define

This item acts like a master switch for the power-saving modes and hard disk timeouts. If this item is set to Max Saving, powersaving modes occur after a short timeout. If this item is set to Min Saving, power-saving modes occur after a longer timeout. If the item is set to User Define, you can insert your own timeouts for the power-saving modes.

Video Off Method Default: DPMS

This item defines how the video is powered down to save power. As a default, this is set to DPMS (display power management software).

Video Off In Suspend Default: Yes

This option defines if the video is powered down when the system is put into suspend mode.

Suspend Type Default: Stop Grant

If this item is set to the default "Stop Grant", the CPU will go into the Idle Mode.

MODEM Use IRQ Default: 3

If you want an incoming call on a modem to automatically resume the system from a power-saving mode, use this item to specify the interrupt request line (IRQ) that is used by the modem. You might have to connect the fax/modem to a mainboard Wake On Modem connector for this feature to work.

Suspend Mode Default: Disabled

If you have selected User Define for the Power Management item, you can set this item to a timeouts from 1 Min to 1 Hour. The system will go into the power-saving suspend mode if the timeout passes without any system activity.

HDD Power Down Default: Disabled

If you have selected User Define for the Power Management item, you can set this item to a selection of timeouts from 1 to 15 minutes. The hard disk drive will power down if the selected timeout passes without any activity on the hard disk.

Soft-Off by PWR-BTTN Default: Delay 4

Under ACPI (Advanced Configuration and Power management Interface) you can create a software power down. In a software power down, the system can be resumed by Wake Up Alarms. This item lets you install a software power down that is controlled by the normal power button on your system. If the item is set to Instant-Off, then the power button causes a software power down. If the item is set to Delay 4 Sec. Then you have to hold the power button down for four seconds to cause a software power down.

Wake Up by PCI Card Default: Disabled

If you enable this item, it allows activity on an add-in card in one of the PCI slots to resume the system from a power-saving mode.

Power On by Ring Default: Disabled

If this item is enabled, it allows the system to resume from a software powerdown or a power-saving mode whenever there is an incoming call to an installed fax/modem. You might have to connect the fax/modem to a mainboard Wake On Modem connector for this feature to work.

Wake Up On LAN Default: Enabled

If this item is enabled, it allows the system to resume from a software powerdown or a power-saving mode whenever there is an incoming traffic to a network (LAN) adapter. You might have to connect the LAN card to a mainboard Wake On LAN connector for this feature to work.

Seconds

CPU Thermal Limit Default: NA Board Thermal Limit Default: NA

These two items can be used to set threshold temperatures for the CPU and the mainboard. If the temperatures are exceeded, the system uses power management to reduce the temperatures.

CPU Thermal-Throttling Default: 50.0%

This item sets the percentage of time that the CPU is idled if CPU throttling is initiated by excess heat.

Resume by Alarm Default: Disabled

If this item is Enabled, it allows you to set a date and time alarm that will automatically resume the system from a software power down. When you enable this feature, new setup items appear to let you set the alarm. Date (of Month) Alarm lets you select a day from 1 to 31. Time Alarm lets you select a time for the alarm in hours, minutes, and seconds.

Primary IDE 0 Default: Disabled Primary IDE 1 Default: Disabled Secondary IDE 0 Default: Disabled Secondary IDE 1 Default: Disabled

When these items are enabled, the system will restart the power-saving timeout counters when any activity is detected on any of the drives or devices on the primary or secondary IDE channels.

FDD,COM,LPT Port Default: Disabled

When this item is enabled, the system will restart the powersaving timeout counters when any activity is detected on the floppy diskette drives, the serial ports, or the parallel port.

PCI PIRQ[A-D]# Default: Disabled

tables for BIOS Error Messages, Codes, Beeps, and Error Symptoms list symptoms along with their probable causes, and direct you to the applicable check procedures to help resolve machine failures. These tables also list the field replaceable units (FRUs) most likely to cause a particular problem.

Check Procedures: When the Start check procedure or the

Index of Symptoms, Messages, Error Codes, or Beeps tables point you to a specific check procedure, proceed to that section. If there are any notes or instructions at the top of the page, read them before you begin with the procedure. Carefully read each step of the check procedure and perform the steps as instructed. If you do not remember the location of a specific part or test point, or an adjustment or removal procedure, see the chapter that contains that information. Always return to the check procedure after you do this. In some cases, you are referred to other check procedures to detect the cause of the failure.

Start This is the entry point for all check procedures. The check

procedures use failure symptoms, Power-On Self Test (POST) error codes, or beeps to help determine the defective field replaceable unit (FRU). Follow the suggested check procedures or use the diagnostics diskette to determine the problem FRU.

IMPORTANT: Replace FRUs ONLY when it is determined that

the error is not a result of software, loose contacts, or dirty component surfaces. Any FRU change should be verified by running a complete test (Diagnostics - All Tests in PC-Doctor diagnostics program).

This book should be used in conjunction with the 2169

diagnostics diskette. This diskette should be used ONLY with Machine Type 2169. Do not use this diskette on other models. See page 71 for information on how to download this diskette.

POST error codes and error messages are displayed on the

screen after the IBM logo. A beep will precede each error code or message. Please refer to “Index of Symptoms, Messages, Error Codes, or Beeps” on page 74 for additional help.

All voltages in the check procedures are positive unless otherwise indicated. Use frame ground for all voltage checks unless otherwise specified.

IMPORTANT: There is a voltage selector on the rear panel of

the machine. Use a flat-head screwdriver to turn the voltage selector to the voltage setting for the area in which you will be using the system.

NOTE: If the check procedures instruct you to replace a FRU

and the error message persists, an option adapter card might be causing the failure. Remove all option adapter cards, one at a time, until the error changes or the problem is no longer apparent. The problem may be in the last card that you removed or something associated with it.

Product Recovery Program menu

Type 2169 has recovery and diagnostics programs on a separate hard drive partition. The recovery CD and Enhanced Diagnostics diskette are not shipped with the machine or the HMM. To download diagnostics tests or to order a recovery CD, see “Enhanced Diagnostics download” or diskette.

IBM PC Enhanced Diagnostics

The IBM PC Enhanced Diagnostics programs use a full

range of diagnostic utilities to determine the operating condition of the computer’s hardware components.

The diagnostic program includes the following:

• PC-Doctor’s Diagnostic Software

This interface serves as the control program for running both the IBM PC Enhanced Memory Diagnostics and the suite of diagnostic tests provided by PC-Doctor.

• IBM PC Enhanced Memory Diagnostics

The memory diagnostic tests determine which memory module (SIMM or DIMM) is defective and report the socket where the failing module is located. The Memory diagnostics can run a quick and full test of the system. Diagnostics can also be run on a single SIMM or DIMM.

• Select pull down menu.

How to Diagnose Combined FRUs: If an adapter or device

consists of more than one FRU, any of the FRUs might cause an error code. Before replacing the device or adapter, remove the FRUs one by one to see if the symptoms change.

If a newly replaced FRU does not correct the problem: If

you have reached this point of the check procedures and were instructed to replace a FRU but doing so did not correct the problem, reinstall the original FRU and go through "Start" again.

If you want to print a copy of a BIOS Setup Utility screen to an

attached printer, press Print Screen key, while the screen is displayed.

PLEASE READ THE FOLLOWING: Human Error is a cause for concern when applied

to check procedures. It exists in every first time set of analysis procedures. It is therefore essential for effective and time-efficient servicing that each stage of every procedure be verified. (For example: When a symptom is found, or when a symptom appears to have been cured; the preceding steps should be repeated for accuracy of analysis.)

symptoms. Go to "Index of Symptoms, Messages, Error Codes, or Beeps" on page 74.

q If there is no error symptom or the error symptom is

intermittent, go to “Undetermined Problems” on page 104.

Index of Symptoms, Messages, Error Codes, or Beeps

How to Use Error Messages: Use the messages, error codes,

and beeps combinations that occur to diagnose failures. If more than one failure occurs, diagnose from the first failure that appears. The cause of the first failure can result in false messages, error codes, or beeps. If you did not receive any messages, error codes, or beeps, see if the symptom is listed in Table 2-3, "Error Symptoms List” on page 79.

ATTENTION: When you have replaced a FRU, you must run

the diagnostics to ensure that no other activity has been affected by the change. This system check can be done through the diagnostics program (Select Diagnostics, then select and execute All Tests from PC-Doctor).

POST: Some diagnostic aids are resident in the machine, such as the Power-On Self Test (POST). The machine performs the POST each time it is powered on. Use this information throughout the diagnostic procedures. The POST is a series of system checks and initializations that verify the correct operation of the base system.

After a successful POST, the system attempts to load operating system. The system can be customized for different startup (boot) methods by the BIOS Setup Utility.

The system's default startup sequence automatically looks for the operating system files in the hard disk if these files are not found in the diskette or CD-ROM.

NOTE: Remember that POST does not test all areas, but

only those that allow the system to operate well enough to run the diagnostics program.

Table 2-1 lists BIOS error codes, messages, and beeps to their possible causes, table 2-3 lists error symptoms and their possible causes. The most likely cause is listed first. Make sure you complete all items in the cause or "Action/FRU" column. When servicing a system, always begin with "Start" on page 68.

If the problem cannot be corrected using these two index tables, go to “Undetermined Problems” on page 104.

NOTES: If an error message and incorrect audio response occur,

diagnose the error message first. If you cannot run the diagnostics program tests but did receive

a POST error code, diagnose the POST error message. If you did not receive any error message, look for a description

of your error symptoms in “Error Symptoms List” in page 79. Check all power supply voltages, switch, and jumper settings

before you replace the system board. Also check the power supply voltages if you have a “system no-power” condition. (“Power Supply Cable Connector Specifications” on page 129

If the problem cannot be corrected by using the “BIOS Error Codes, Messages, And Beeps List” table and “Error Symptoms List” table, go to "Undetermined Problems” on page 104.

Troubleshooting

Failing Parts or Assemblies: The check procedures generally

help you trace a problem to one part or assembly. The last step of the specific check procedure you are using indicates that a part or assembly is failing. You should inspect the part or assembly before you decide to replace it. It might be loose, dirty, or in need of a small repair. The check procedures might lead you to two, or even three, possible failing parts or assemblies. The parts that might be failing are listed in order of the most probable failure. Also, the FRU parts are defined as replaced units and are not repaired in the field.

Measuring Voltages: Some check procedure steps instruct you to measure voltages on cable plugs and electronic board connectors. If you are asked to measure voltage at several places on a plug or connector, a chart next to or near the instruction indicates the number of the plug or connector, the pin numbers you should measure, the signal name, and the correct voltage for the condition you are measuring. Measure the voltage only at the pins listed in the chart. Remember to set the meter on the correct scale and to put the meter leads in the correct position for the voltage you are asked to measure.

NOTE: Use frame ground as the ground reference. Attach

the black (ground) lead of meter to frame ground, except where specified otherwise.
