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. Remove the access panel.(see Figure 1 below)
2. Disconnect the cables from the board.(see Figure 2-5 below)
3. Remove the HDD from the cage.(see Figure 6 below)
4. Remove the power supply from the chassis.(see Figure 7&8 below)
5. Remove the system fan.(see Figure 9&10 below)
6. Remove the memory card from the board.(see Figure 11 below)
7. Remove the CPU from the system board .(see Figure 12-14 below)
8. Remove the battery from the system board.(see Figure 15 below)
9. Remove the system board from chassis.(see Figure 16&17 below)
10. Remove the front panel.(see Figure 18 below)
11. Remove the ODD from the chassis.(see Figure 19 below)
12. Remove the front I/O and power LED cable.(see Figure 20 below)
13. Remove the HDD, ODD, and PCI latches from the chassis.(see Figure 21-24 below)
14. Remove the fan guard from the fan.(see Figure 25 below)
15. Remove the power supply cover.(see Figure 26&28 below)
16. Remove the power supply PCA, and then disconnect the power cables.(see Figure 29&30 below)
17. Disconnect the power cables.(see Figure 31 below)
18. There are seven different possible power supplies in these computers. Use figures 32-38 to determine which power
supply you have, and then remove the electrolytic capacitors as shown in the appropriate figure.
3.2 Optional Graphic. If the disassembly process is complex, insert a graphic illustration below to identify the items
contained in the product that require selective treatment (with descriptions and arrows identifying locations).
