NOTE: The computer's BIOS may not support hard-disk drives obtained from vendors other than Dell. Dell does not guarantee compatibility or provide support for hard-disk drives obtained from other sources. To install a hard-disk drive, perform the following steps. NOTICE: To prevent data loss, shut down your computer before removing or installing your hard-disk drive. Do not remove the hard-disk drive if the computer is in suspend mode or save-to-disk mode or if the hard-disk drive access indicator is lit.
There may be some resistance as the drive connects to its interface connector at the back of the bay. 7. Tighten the screws you loosened in step 3. 8. Test the drive by running the Hard-Disk Drives (Non-SCSI) test group in the Dell Diagnostics. For information on running the diagnostics, see "Running the Dell Diagnostics" in Chapter 3 of the Dell Inspiron 7500 Reference and Troubleshooting Guide.
To deactivate the embedded keypad, press . The Num Lock indicator is no longer illuminated. When the embedded keypad is activated, the key combinations in Table 1 temporarily disable specific keypad keys. Table 1.
To move the cursor, lightly slide your finger over the smooth sensor area. To select an object, gently tap once on the surface of the touch pad. To select and move (or drag) an object, position the cursor on the object and tap down-up-down on the touch pad. On the second down motion, leave your finger on the touch pad and move the selected object by sliding your finger across the surface. To double-click an object, position the cursor on the object and then tap twice.
l One Type I card and one Type II card (using either connector) l Two Type I cards or two Type II cards l A single Type III card (using the bottom connector) The type of card refers to its thickness, not its functionality. Because a Type III card is thicker than Type I and Type II cards, it takes up the entire PC Card slot, although it uses only one PC Card connector. PC Cards are generally marked (with a triangle or an arrow) to indicate which end should be inserted into the slot.
NOTE: When the external monitor and built-in display are used simultaneously, the refresh rate is always 60 hertz (Hz).

Back to Contents Page Power Conservation: Dell™ Inspiron™ 7500 How to Conserve Battery Power Experimenting with Power Conservation Using Microsoft Windows 98 to Conserve Battery Power Standby Mode Using Windows NT to Conserve Battery Power Save-to-Disk Suspend Mode How to Conserve Battery Power l l You automatically conserve battery power each time you attach your computer to an electrical outlet. When the AC adapter is attached, the battery is being charged while the computer uses AC power.
Using Windows NT to Conserve Battery Power To access the Power Management Control window (see Figure 2) and set the power management features in Windows NT, perform the following steps: 1. Click the Start button, point to Settings, and click Control Panel. 2. Double-click the Softex Power Management icon.
Experimenting With Power Conservation In general, the lower the value you set for each time-out option, the longer your battery's charge lasts. On the other hand, setting high time-out values tends to optimize the computer's performance. For best results, experiment as follows: l Use the computer with all the options set at their default values. l Use the computer with all the time-out options disabled or set to Off. l Use the computer with all the time-out options set to their minimum values.
