2 Dell Inspiron 7500 — Removing and Replacing Parts
Precautionary measures include disconnecting the computer from the AC adapter and
port replicator and removing the main battery, PC Cards, hard-disk drive, memory
module cover, memory modules, and devices in the media bay.
To take these precautionary measures, perform the following steps:
1. Determine the power state of the computer.
If the system is on, go to step 2. If you are unsure whether the system is on, shut
down and restart the system, and then go to step 2.
2. Turn off any attached peripherals, and then shut down the computer.
3. Disconnect the computer and any attached peripherals from electrical outlets to
reduce the potential for personal injury or shock.
If the computer has an AC adapter, disconnect the AC power cable (see Figure 1)
from the electrical outlet and then from the AC adapter; then disconnect the AC
adapter from the computer or from the Inspiron Port Replicator.
