2.0 Tools Required List the type and size of the tools that would typically be used to disassemble the product to a point where components and materials requiring selective treatment can be removed. Tool Description Tool Size (if applicable) Description #1 Phillips screwdriver Description #2 Dikes Description #3 Torx screwdriver T-15 3.0 Product Disassembly Process 3.1 List the basic steps that should typically be followed to remove components and materials requiring selective treatment: 1. 2. To remove the access panel, loosen the thumbscrew on the rear of the computer (1), slide the access panel toward the front of the computer, then lift it off (2) (see Figure 1). To remove the front bezel: a. Lift the fan and shroud assembly up and place it on top of the optical drive to access the front bezel release tabs (see Figure 2). b. Press the two release tabs on the inside of the bezel towards the right side of the computer (1) and rotate the bezel off from right to left (2) (see Figure 3). Remove or cut all expansion cards, cables, and any other devices from the system board. To remove the system board: a. Remove the hard drive cage. b. Remove the front I/O panel. c. Remove the heatsink from the system board by loosening the four captive screws that secure the heatsink to the system board, and then lifting the heatsink from the system board. d. Remove the five screws that secure the system board to the chassis (see Figure 4). e. Slide system board toward the front of the unit until the rear connectors are clear of their slots in the chassis. To remove the battery: Locate the battery and battery holder on the system board. Depending on the type of battery holder on the system board, complete the following instructions to remove the battery. TYPE 1 BATTERY HOLDER (see Figure 5): Lift the battery out of the holder. TYPE 2 BATTERY HOLDER (see Figure 6): To release the battery from its holder, squeeze the metal clamp that extends above one edge of the battery. When the battery pops up, lift it out. TYPE 3 BATTERY HOLDER (see Figure 7): Pull back on the clip that holds the battery in place, and then remove the battery.

P14 Additional information All 1. Product environmental information contained in this declaration is valid as of the date the declaration is published. Changes to sections external standards referenced in the IT Eco-Declaration may invalidate some information contained in this declaration over time. P9 1. Energy efficiency data listed is for an ENERGY STAR compliant product if offered within the model family. HP computers marked with the ENERGY STAR Logo are compliant with the applicable U.S. Environmental Protection Agency (EPA) ENERGY STAR specifications for computers. If a model family does not offer ENERGY STAR compliant configurations, then energy efficiency data listed is for a typically configured model. 2. For more information about HPs ENERGY STAR qualified products, go to hp.com: http://www.hp.com/ and select the applicable market segments and product categories for more information. 3. Energy Efficiency information published on the ECMA 370 The Eco Declaration represents a typically configured product base model meeting ENERGY STAR specifications if offered within the model family. If optional components or modules are added, like extra hard disks or graphic cards etc, these can change the energy efficiency data listed above. 4. Power consumption in the Off / Apparent Off mode is measured and reported with the network interface controller (NIC) WOL disabled. P10 1. Acoustic noise information published on the ECMA 370 The Eco Declaration represents a typically configured product base model only. If optional items with moving parts are added, like extra hard disks or graphic cards with fans etc, these can change acoustic noise values for which HP can take no responsibility.
