Dell™ Inspiron™ 6400/E1505 Owner's Manual

Internal Card With Bluetooth® Wireless Technology

Before You Begin

This chapter provides procedures for removing and installing the components in your computer. Unless otherwise noted, each procedure assumes that the following conditions exist:

You have performed the steps in "Turning Off Your Computer" and "Before Working Inside Your Computer" (see Before Working Inside Your Computer).
You have read the safety information in your Dell™ Product Information Guide.
A component can be replaced—or if purchased separately—installed by performing the removal procedure in reverse order.

Recommended Tools

The procedures in this document may require the following tools:

Small flat-blade screwdriver
Phillips screwdriver
Small plastic scribe
Flash BIOS update (see the Dell Support website at support.dell.com)

Turning Off Your Computer

NOTICE: To avoid losing data, save and close any open files and exit any open programs before you turn off your computer.

Shut down the operating system:
1. Save and close any open files, exit any open programs, click the Start button, and then click Turn Off Computer.
1. In the Turn off computer window, click Turn off.

The computer turns off after the operating system shutdown process finishes.

Ensure that the computer and any attached devices are turned off. If your computer and attached devices did not automatically turn off when you shut down your operating system, press and hold the power button for several seconds until the computer turns off.

Before Working Inside Your Computer

Use the following safety guidelines to help protect your computer from potential damage and to help ensure your own personal safety.

CAUTION: Before you begin any of the procedures in this section, follow the safety instructions in the Product Information Guide.

CAUTION: Handle components and cards with care. Do not touch the components or contacts on a card. Hold a card by its edges or by its metal mounting bracket. Hold a component such as a processor by its edges, not by its pins.

NOTICE: Only a certified service technician should perform repairs on your computer. Damage due to servicing that is not authorized by Dell is not covered by your warranty.

NOTICE: When you disconnect a cable, pull on its connector or on its strain-relief loop, not on the cable itself. Some cables have a connector with locking tabs; if you are disconnecting this type of cable, press in on the locking tabs before you disconnect the cable. As you pull connectors apart, keep them evenly aligned to avoid bending any connector pins. Also, before you connect a cable, ensure that both connectors are correctly oriented and aligned.

NOTICE: To help prevent damage to the computer, perform the following steps before you begin working inside the computer.

Ensure that the work surface is flat and clean to prevent the computer cover from being scratched.
Turn off your computer. See Turning Off Your Computer.

NOTICE: To disconnect a network cable, first unplug the cable from your computer and then unplug it from the network wall jack.

Disconnect any telephone or network cables from the computer.

NOTICE: To help prevent damage to the system board, you must remove the battery from the battery bay before you service the computer.

NOTE: To avoid damage to the computer, use only the battery designed for this particular Dell computer. Do not use other batteries designed for other Dell computers.

Disconnect your computer and all attached devices from their electrical outlets, slide and hold the battery-bay latch release on the bottom of the computer, and then lift the battery from the bay.

Remove Keyboard, memory, WIFI card, CDROM, and hard drives from HP Pavillion DV9000 Series Laptop

FreeDriverSiteAdmin — Sun, 21 Jun 2009 07:06:21 GMT

These instructions will help you remove hard drive, memory, wireless card and keyboard from a HP Pavilion dv9000 series laptop. All these components, except the keyboard, can be accessed through the bottom of the laptop.

In the next guide I will explain how to disassemble laptop display panel and remove inverter board with LCD screen.

Do not disassemble your laptop if it’s still covered by the manufacturer’s warranty or you loose the warranty. Are you looking for spare parts for your HP Pavilion dv9000 laptop? Search here.

First of all, remove the battery. Remove screws from the 1st hard drive and memory covers. Remove both covers.

Under the memory cover you will find the wireless card and RTC battery.

In order to remove the hard drive, lift up the right side of the drive assembly (move 1) and then pull it to the right (move2). If you are replacing the hard drive, you’ll have to transfer the caddy and connector to the new drive.

Before you remove the wireless card, you’ll have to disconnect both antenna cables pointed with green arrows. Simply unsnap both antenna cables from the wireless card with your fingers. After that remove two screws securing the wireless card and pull it from the slot by the edges.

Some Pavilion dv9000 laptops have only one hard drive installed. As you see, in my case there is no second hard drive under the cover.

If you would like to install second hard drive into your notebook, you’ll have to purchase a new SATA drive, SATA connector and drive caddy. You’ll find step by step hard drive installation instructions in this guide.

we will refer to all HP Pavilion dv9000, dv9000t, dv9100, dv9200, dv9300, dv9400, dv9500, dv9600 & dv9700 notebooks as the “dv9000″ since adding a hard disk drive (HDD) to all above mentioned notebooks are similar.

In order to remove the CD/DVD drive you’ll have to remove the securing screw (1) and then carefully pull the drive from the laptop.

KEYBOARD REMOVAL INSTRUCTIONS

Remove six green screws securing the keyboard bezel and one red screw securing the keyboard.

Carefully start removing the keyboard bezel with a small flathead screwdriver.

Be very carefull, the bezel is attached to the motherboard with a flat ribbon cable. The cable location is pointed by the green arrow. Do not disconnect this cable. Simply place the bezel as it shown on the picture below.

Remove three screws securing the laptop keyboard.

Lift up the keyboard. Be carefull, it’s connected to the motherboard.

In order to release the keyboard cable, you’ll have to unlock the connector as it shown on the picture above.

1. Slide the connector lock to the direction shown by two green arrows with your fingernails.

2. Pull the keyboard cable from the connector.
