Use caution when removing the grounding eyelets, as they can be broken off easily. If this happens, the assembly must be replaced. To prevent the eyelets from breaking, bend the grounding eyelet tabs at the farthest point from the eyelet.
11. To remove the Display from the Top Case, the display cable and two grounding cables must be guided through the holes in the Top Case. Replacement Procedure 1. Guide the display posts, display cable and two grounding cables on the Display through the holes in the Top Case. 2. Replace the grounding eyelets over the display posts (see Figure 16). Use caution when replacing the grounding eyelets, as they can be broken off easily. If this happens, the assembly must be replaced. 3.
5. To reconnect the display cable, position a probe in the cable as shown in the below illustration. Figure 17 - Display Cable Probe Position 6. Use the probe to connect the display cable into the connector as shown below. Use caution to keep the OmniBook on a level surface. With the Top Case partially separated, small internal parts may dislodge when the OmniBook is tilted at a sharp angle. Figure 18 - Reconnecting Display Cable 7.
Acceptable to reassemble All eyelets are present. Figure 19 - I/O Port Eyelets (all present) Acceptable to reassemble There are two matched sets and at least one eyelet in each position.

Appendix B - Power On Self Test Codes Beep Codes Beep Codes are used to identify a Power On Self Test (POST) error that occurs when the screen is not available. Once the screen is operational, diagnostic messages are reported to the screen. There are beep codes for both fatal and nonfatal system board errors. The codes are shown as x-y-z where 2-2-1 represents 2 beeps - pause - 2 beeps - pause - 1 beep.
Display Codes There are a number of Power On Self Test (POST) tests that are performed after the Beep Code tests. Failure of one or more of these tests will result in a displayed failure code (such as 0240). It is extremely important not to interpret a failure code immediately as a hardware failure. The failure should be confirmed with a clean boot.

Appendix C - Password Policy If the user forgets the system password, there is a master password that will unlock the OmniBook. The user calls Technical Support to determine this master password as follows: 1. Support will tell the user the keys to type at the password entry screen: [alt][shft][f10] 2. The OmniBook generates and displays an encoded master password. This is displayed under the normal password entry area.
Further, you must log the name, serial number and date of the running of the descramble program, and file the written backup with the log. The log and backup are subject to standard record retention process and review.
