Removing and Replacing Parts
NOTICE: Only a certified service technician should perform the procedures 
for removing and replacing parts. The warranty on the computer becomes 
void if anyone other than a certified technician performs these procedures.
Unless other wise noted, each procedure assumes the following:
You have the recommended tools.
You have performed the steps in Precautionar y Measures.
The computer and any attached peripherals are turned off and the peripherals are 
disconnected from the computers input/output (I/O) panel.
You can replace or reinstall a part by performing the removal procedure in reverse 
order unless additional information is provided.
Precautionary Measures
NOTICE: Only a certified service technician should perform the procedures 
for removing and replacing parts. The warranty on the computer becomes 
void if anyone other than a certified technician performs these procedures.
WARNING FOR YOUR PERSONAL SAFETY AND PROTECTION OF THE 
EQUIPMENT
Before you start to work on the computer, perform the following steps in 
the sequence indicated:
1. Ground yourself by attaching an antistatic grounding strap to your wrist 
and to an unpainted metal surface on the computer’s I/O panel. If an anti-
static grounding strap is not available, periodically discharge static 
electricity from your body by touching one of the connectors on the I/O 
panel.
2. Turn off the computer and any attached peripherals.
3. Disconnect the computer and any attached peripherals from electrical out-
lets to reduce the potential for personal injury or shock. 
						

							2 Dell Inspiron 7500 — Removing and Replacing Parts
Precautionar y measures include disconnecting the computer from the AC adapter and 
port replicator and removing the main battery, PC Cards, hard-disk drive, memor y 
module cover, memory modules, and devices in the media bay.
To take these precautionar y 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.

4. If the computer is connected to a port replicator (see Figure 2), pull both release 
handles on the sides of the replicator to undock the computer. 1AC  p owe r  c a b l e
