[. . . ] HP OmniBook 4000C/CT Familiarization Guide This guide is for experienced HP Response Center personnel, CEs, and reseller technicians, such as personnel who have already completed the HP Vectra PC family training course, or equivalent, and have at least six months of experience servicing the HP Vectra PCs. It is a self-paced guide designed to train you to install, configure, and repair the OmniBook Notebook PC. You can follow it without having any equipment available.

[. . . ] If the user forgets the password at another time, it will require another call to Support. (If the user presses the appropriate keys by mistake, pressing [ESC] will allow entering the stored password. ) ___________ 17 Password Decode Policy The password descramble programs for the HP OmniBook PCs are protected as HP Company Private information. They may not be copied, backed-up, printed or distributed. There are only six official copies of each program. In addition to protecting the program itself, it's use is also controlled. HewlettPakard and authorized support providers must ensure with written evidence that the OmniBook that is being "descrambled" is actually in the hands of the unit's actual and current owner. This requires a sales receipt showing the unit serial number and owner's name, or a written statement from the owner attesting that they are the owner of the unit. The statement can be a FAX copy of the document. The fact that the unit is in the hands of an HP representative on the behalf of the customer is not evidence of ownership. In addition, HP will not descramble a unit for any non-owner, even if it involves law enforcement agencies. If you receive such a request, you should notify management and HP Corporate Legal immediately. (These requests may require a court order prior to our participation. ) 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 is subject to standard record's retention process and review. The final issue relating to descramble of passwords is that HP cannot provide information to users that would assist them in improperly descrambling a password and opening a unit. ___________ 18 Notebook Hardware Structure Field Replaceable Assemblies Installing memory (End User Replaceable) The OmniBook 4000 family has two memory locations for expanding system RAM. The memory location on the side of the OmniBook that has the battery also has the factory RAM module installed. To add an additional 8MB or 16MB of RAM, use the location on the other side of the unit near the floppy drive. If the base unit has 4MB or 8MB of memory, and you want to expand the memory to more than 20MB or 24MB, then the original 4MB or 8MB module must be replace with a larger module.

A second Battery Module may be installed in the Floppy Disk Drive Bay. This doubles the battery life of the OmniBook 4000. To remove either module, turn the OmniBook over. Squeeze the two levers together and slide the module forward. Reverse the procedure to install a new Battery or Floppy Disk Drive Module.
