All Power Management functions can be configured from the Setup Configuration Utility (SCU), described later in this chapter. Automatic Power Management Automatic Power Management operates at two levels as described in the following paragraphs. Local Power Management Local Power Management controls computer subsystems. When a subsystem is inactive for a period of time, it is automatically shut down or slowed to reduce power consumption. The subsystem returns to an active state when it is accessed. Subsystems under Local Power Management include: s s s s Hard disk drive Diskette drive CD-ROM drive LCD display panel Global Power Management Global Power Management automatically puts the computer into Suspend mode when the computer is inactive for a period of time. The computer wakes up whenever activity resumes. The timeout settings for Suspend mode are set up in the SCU program. The computer uses Suspend-to-RAM (Standby) or Suspend-to-Disk (Hibernation) depending on the Suspend Data To setting in the SCU program. AMD PowerNow! NOTE: This power mode is available only on the Compaq Notebook 100 Personal Computer. Processor clock speed and voltage are automatically reduced based on an AMD proprietary weighted average. The "High Performance," "Automatic," and "Battery Save" modes can be set up and switched based on the power source to allow you to customize system performance and battery life. 1-6 Product Description Suspend mode can be initiated at any time in either of two ways: Manual Power Management Suspend mode can be initiated at any time in either of two ways: s s By pressing Fn+F12. By closing the top cover, if the Cover Close option is set to Suspend in the SCU program. Suspend-to-Disk (Hibernation) When the computer suspends to disk, the system preserves all the running application programs as a file in a Suspend-to-Disk partition on the hard disk. The computer then turns off automatically. When the computer is powered on, the system reads the file from the Suspend-toDisk partition back into memory, returning the computer to the state it was in before it was suspended. If there is no Suspend-to-Disk partition on the hard disk, use the HIBERNATE utility to create the partition, in order to be able to use the Suspend-to-Disk feature. The HIBERNATE utility is available as SoftPaq SP13934. Suspend-to-RAM (Standby) When the computer suspends to RAM, several subsystems enter standby or power-off mode to conserve power. The system wakes up when any key is pressed. Resume Timer and Ring Resume options also wake the system from Suspend-to-RAM. 1.4 Setup Configuration Utility (SCU) The system comes with a Setup Configuration Utility (SCU). This utility configures BIOS settings by using menu-driven utilities. Settings are stored in the CMOS RAM. The SCU must be used when: s s s An error message indicates that the SCU should be run. Factory default settings need to be restored (after BIOS upgrades). Specific settings must be modified. Product Description 1-7 Starting the SCU The SCU resides on the system ROM chip.

When troubleshooting the Compaq Armada 100S and Notebook 100, it is important to obtain all facts about the error condition. Obtain details of the problem and any circumstances surrounding the problem. Obtain all error codes or beep codes. Once all facts have been gathered, determine possible causes and search for issues. 1-16 Product Description 1.5 Compaq Configuration Record Utility Compaq Configuration Record Utility is an online information-gathering tool meant to replace the DOS-based Inspect utility. It runs from within Windows and gathers critical hardware and software information from various sources to give a complete view of the computer. The Compaq Configuration Record Utility delivers comprehensive configuration capture, provides a means for automatically identifying and comparing configuration changes, and has the ability to maintain a computer configuration history. The information can be saved as a history of multiple sessions. The Compaq Configuration Record Utility captures data as sessions; a session is defined as an organized group of data describing the configured state of the system at a specific point in time. The session information is maintained in a log file, located in the same directory as the executable portion of the program. This file contains all of the ASCII text configuration information captured for a session. This file can be analyzed locally by the Configuration Record Utility, or it can be sent to another location such as a help center, or to Compaq. The sessions are organized as two distinct types: s Active--The Active session (referenced as session now.log) is the most recent information captured. The utility overwrites this session each time a sample is taken. Original--The Original session (referenced as session base.log) is the first session sampled. The Compaq Configuration Record Utility will treat this session as a "master configuration," and the utility will never overwrite this session. s Product Description 1-17 1.6 Information Gathering The comparison feature provides several reports that enable the administrator to specify the particular type and level of information that will be most useful in a particular case. The different report types available are Show Only Differences and Show Details and Differences. Show Only Differences Report This feature provides a mechanism for filtering the level of information displayed when comparing two different configuration snapshots (or sessions). For example, when a user requests the Configuration Record Utility to generate a comparison of sessions using the "differences" filter, the tool automatically compares those two sessions (which are already stored in a Configuration Record file). It then generates a report that shows only the differences between the two generations. In this case, the differences report will include all information recorded, such as changes in amounts of free memory. Reviewing the differences occurring between different configuration snapshots can help identify trends causing intermittent computer problems, such as low memory resources. 1-18 Product Description Show Details and Differences Report This report provides the level of detail that is necessary for service personnel to get a clear picture of the system configuration. It provides a much greater depth of information on hardware, operating system services, and drivers that are running on the computer. The Compaq Configuration Record Utility is supported under Windows 95, Windows 98, and Windows NT 4.0. This utility is available on SoftPaq.

Obtain details of the problem and any circumstances surrounding the problem. Obtain all error codes or beep codes. Once all facts have been gathered, determine possible causes and search for issues. 2.2 Basic Troubleshooting Checklist Use the following checklist in the event minor problems are encountered: s Is the computer connected to an external power source or does it have a fully charged battery pack installed? Is the computer turned on and is the power indicator illuminated? Are all cables connected properly and secure? Did the diskette drive contain a non-bootable diskette when the system was powered up? Does the computer have all necessary device drivers? Have printer drivers been installed for each application? Was the Windows operating system properly exited? Has the computer hard drive been scanned for viruses? s s s s s s s Troubleshooting 2-1 2.3 Power-On Self Test (POST) When the computer starts, the system BIOS runs a series of internal checks on the hardware. This allows the computer to detect problems as early as the power-on stage. The POST alerts you to problems by displaying error messages. If POST detects an error, the system displays an error message on the display. If the error occurs before the display comes up, error codes or system beeps indicate the POST error. The value for diagnostic POST (378H) is written at the beginning of the test. Therefore, if the test fails, you can determine where the problem occurred by reading the last value written to POST 378H by the PIO Debug Board Plug at the PIO port. The following table lists error codes in sequential order on the PIO Debug Board. Table 2-1 Error Codes Code 01h 02h 03h 04h 05h 06h 07h 08h 09h 0Ah 0Bh 0Ch 0Fh 10h 11h Description Start of boot loader sequence. Initialize chipset. Memory sizing.
