1.3.3
Hard Disk Subsystem
The TM5000 Notebook family features a user-replaceable, 2.5 inch, (initially
either 810 million byte or 524 million byte capacity) enhanced IDE interface
Hard Disk Drive. Both drives have a 128KB buffer and can transfer data in
or out of the buffer at a 4.5 MB/second rate across the ISA Interface using
the 2 of 7 RLL code recording method.
The hard drive also features built-in power conservation features configured
from the standard CMOS Setup Routine. An Automatic Power Down mode
can be selected which powers down the drive motor during periods of
inactivity. An additional level of power conservation may also be selected
which powers down the motor plus all control circuits.
The hard drives are factory formatted as a single drive (Drive C:) and are
preloaded with software (MS-DOS, Windows and TI Utilities).
In all Pentium-based notebooks, the hard drive is connected to the VL-local
bus for increased performance.
1.3.3.1
Access to Hard Disk Drive
Access to the hard drive is provided through a removable panel on the
bottom of the notebook (removal/replacement instructions for the hard
drive are provided in Section 5).
1.3.4
Floppy Diskette Subsystem
The notebook series include a front-mounted, 3.5 inch floppy diskette drive
which is capable of reading/writing 1.44 MB floppy diskettes. An activity
indicator for the floppy drive is located along the front edge of the notebook.
1.3.5
Keyboard Subsystem
The TM5000 Notebook uses an 83-key keyboard (84 keys for international
versions) similar in layout to the TM4000E Notebook Keyboard emulating all
functions of an IBM AT-101/102 keyboard. A Special Function key (
Fn
allows some of the TM5000 keyboard keys to take on additional functions
See Figure 1-10).
The keyboard’s 4mm key travel gives the touch and feel of a full-size
workstation keyboard. The Point, which is a pressure-sensitive mouse
device, is embedded in the keyboard. The select switches for the built-in
mouse device are located just below the keyboard.
Some of the major features of the keyboard include:
•
4-mm Key movement
•
Integrated numeric keypad
•
"Inverted T" Cursor Control Key Layout
