Back to Contents Page Power Management: Dell™ Inspiron™ 2000 System Reference Experimenting With Power Conservation Standby Mode Using Key Combinations Suspend-to-Disk (Hibernate) Mode Closing the Display Power Management Properties for Windows 98 Suspend Mode Power Management Properties for Windows NT Experimenting With Power Conservation In general, the lower the value you set for each power conservation feature, the longer thebattery's charge lasts.
Suspend Mode If your computer is running the Microsoft Windows NT® operating system, suspend mode stops almost all computer activity, but leaves the computer ready to resume operations immediately in about 20 to 30 seconds. Use suspend mode whenever you leave the computer unattended. NOTICE: Windows NT saves data to random-access memory (RAM), not to your hard-disk drive, before entering suspend mode.
To access the Power Management Properties window and set the power management features, perform the following steps: 1. Click the Start button, point to Settings, and click Control Panel. 2. Double-click the Power Management Properties icon.

Back to Contents Page Installing Drivers: Dell™ Inspiron™ 2000 System Reference All of your computer’s drivers for Dell-installed devices are operative when you receive the computer. No further installation or configuration is needed. However, if you ever need to reinstall any of these drivers, the driver files are provided on the System Software CD. Often device problems can be corrected by reinstalling the appropriate drivers.
Back to Contents Page Error Messages and IRQ Assignments: Dell™ Inspiron™ 2000 System Reference Error Messages IRQ Assignments Error Messages Your application programs, operating system, and the computer itself can identify problems and alert you to them. When this occurs, a message may appear on the computer's display or on an external monitor (if one is attached). If an error message appears on the display or external monitor, make a note of the message.
0270:Real time clock error The CMOS battery that supports data stored in NVRAM may be dead. 0231:Shadow RAM failed at offset: nnnn Shadow RAM failed at address nnnn. Call Dell for technical assistance. 0210:Stuck Key If the built-in keyboard is being used, it may be faulty. A key on the built-in keyboard may have been pressed while the computer was booting. Run the Stuck Key test in the Dell Diagnostics. If the problem cannot be corrected, call Dell for technical assistance.

Back to Contents Page Ports and Connectors: Dell™ Inspiron™ 2000 System Reference About the I/O Connectors AC Adapter Mouse, Keyboard, and External Numeric Keypad Audio Devices USB Devices Modem Connector Parallel Devices NIC Connector External Monitor External Media Options About the I/O Connectors You can connect external devices to the input/output (I/O) connectors on the back and left side of the computer (see Figure 1).
NOTE: If the computer is in suspend (or standby) mode or S2D mode when you attach an external keyboard, the device is recognized immediately by the computer when it resumes normal operation. You can use the computer's keyboard and an external keyboard at the same time. When you attach a keyboard to the computer, the embedded numeric keypad is automatically disabled.
The drive access indicator does not blink when data is being accessed from the diskette drive connected to the parallel connector. NOTICE: Protect the diskette drive when it is not in the external media bay. Do not squeeze the drive or place objects on top of it; doing so could damage the drive motor. External Monitor You can use the 15-pin video connector to attach an external monitor to the computer. Connecting an External Monitor To attach an external monitor, perform the following steps.
Modem Connector You can connect a telephone line to the integrated modem through the RJ11 modem connector on the back of the computer. NOTICE: Do not confuse the modem and NIC connectors on your computer. Do not plug a telephone line into the NIC connector. NIC Connector You can connect to the integrated network interface controller (NIC) through the RJ45 connector on the back of the computer. NOTICE: Do not confuse the modem and NIC connectors on your computer.

Back to Contents Page Power Sources: Dell™ Inspiron™ 2000 System Reference AC Adapter Batteries Turning On the Computer AC Adapter The AC adapter converts AC power from an electrical outlet to the DC power used by the computer. The AC adapter kit includes the AC adapter with its attached DC cable (which connects to the computer) as well as an AC power cable that connects the adapter to an electrical outlet. You can connect the AC adapter with your computer either turned on or off.
l The battery’s self-test capability alerts you to battery conditions such as low charge. NOTE: If the battery is totally drained the alert functions will not operate. l You can charge the battery whenever you like without fear of reducing its charge capacity. l A battery has a life span of up to 350 full charges and 2000 partial charges, provided it is charged at normal room temperature. NOTICE: The batteries are designed to work only with Dell Inspiron 2000 portable computers.
Charging a Hot Battery If your battery is hot from being used in your computer or being in a hot environment, take note of the following precautions: l l A hot battery will not charge when you connect the AC adapter to the computer. This safety feature is important because charging a hot battery shortens the battery’s life span and may damage the battery and the computer. If the computer is not allowed to return to room temperature, the battery stops charging before it reaches its full capacity.
1 Battery charge indicators (4) 2 Battery test button NOTES: A charge indicator that blinks rapidly indicates a temporary failure or a potentially recoverable failure such as overheating. Allow the battery to cool for several minutes before checking the charge level again. If the battery has permanently failed or completely discharged, no charge indicators will light when you press the battery test button.
Battery Disposal CAUTION: Do not puncture or incinerate the battery. NOTE: To purchase a new battery, call Dell or access the Dell World Wide Web site at http://www.dell.com. Your computer system uses both a lithium-ion battery pack and a nickel-metal hydride (NiMH) coin cell battery. For instructions about replacing the lithium-ion battery pack in your computer, see "Replacing the Battery." The NiMH battery is a long-life battery, and it is very possible that you will never need to replace it.
