Note: The hard disk drive can be removed by the user for easy upgrades. The hard
drive is located on the bottom case and with the removal of one screw the hard drive
can be removed. The hard drive plastic case on the OB5000 is changed from the
OB4000 due to a design change requirement; therefore, they are not
interchangeable between platforms.
Internal 3.5 inch, 1.44-MB flexible disk drive is standard on all models. The flexible
disk drive can be easily removed by the user and replaced with an additional battery
pack to double battery life. This is part of the modularity features of the OmniBook
5000.
