Unleash the Power Cord
The 10-foot Power Cord is tucked inside the back of the cabinet.
Looking at the back of the cart, find the grommet hole beside the right
handle. Thread the plug through the grommet hole, pull the cord
through, and wind around the handle.

Always Turn Off the Power to the
Cart before Plugging In Or Out!
Setting the Combination Locks
Your new Intelligent Laptop Computer Cart comes equipped with two
re-settable Combination Padlocks. You can program them with the
same combination or different combinations – the choice is yours.
Each lock starts with 0-0-0-0. Follow the directions with the lock for
changing the combination. Remember to depress the shackle before
un-engaging it from the lock.

Maximize your technology investment
Unique Power Management & Control System (patent
pending) gives you the ability to:
Extend the battery life of your computers with one touch!
Save on energy costs – the “Brain” knows the more
charged a battery, the less power it requires.
Designed for the IT Coordinator,
the Instructor & the Student
Easy set-up for the IT Coordinator
Easy to maintain by the Instructor
Easy to use for the Student
Color-Coded Labeling System helps keep you
in control and your investment organized.
Power Strips A & B & C are controlled by the “Brain”, which shifts the
power from one strip to the other, and even allows a “Turbo Charge”, where all
available power is sent to either Power Strip A or B or C – Steps 3 & 4 & 5
Cut Here - Finished size = 16”W x 11”H - Folded three times, like a map
All about Safety & Security
Peace of mind, knowing that the entire cart is UL Listed not just the electrical units. So your students - your real
technology investment - are safe and secure.

• Only One Electrical Plug to the wall outlet reduces nuisance tripping of circuit breakers.
• “Round Robin” sequencing evaluates the demand for power from each electrical strip of ten computers, concentrating on those batteries that have the most
demand for power.
• “Round Robin” also allows each electrical strip time to cool down. Cooler batteries last longer, and extended battery life saves you money.
• A Divider Panel separates the computer/battery from the transformer, minimizing the transformer’s heat impact on the battery … cooler batteries last longer.
• The Brain recognizes as batteries become charged, and sends only enough power to keep the batteries well within their thermal limits, drawing only the
required power and saving you money.
• A single Mode Button lets you cycle through the various settings, while the LED lights help keep track of what the power system is doing.
• Two Auxiliary Outlets on the top of the cart let you use a video projector or a printer with confidence, since the Brain will dedicate the power to those
accessories when you need to use them. Accidentally overloading the circuit is minimized!

Green light glows as long as the Red Power Switch is
turned on. Power is now on inside the laptop cart.
Always-On Electrical Outlet stays on as long
as the Red Power Switch is on. (see below)
Left alone, the Brain will automatically turn on the Yellow light, which
means that all power is being sent to charge the computer batteries.

Always-On Electrical Outlet
Under the Brain, accessible from the rear of the
cart, is one unique Electrical Outlet, rated for 1
Amp. This outlet is for a Wireless Access Point.
The Wireless Access Point’s power
cord can be routed through the cart at
the side cord-pass-thru-hole, opposite
the cart’s power cord. Remember, the
outlet is maximum 1 Amp, only.
ELECTRICAL: Avoid sparks. Avoid arcing Always turn OFF the power to the cart before plugging IN or OUT!
ELECTRICAL: For Safety Purposes, make sure all electrical components do not exceed the the maximum load rating of 12 amps.
ELECTRICAL: Risk of electrical shock. Do not plug the power cord into another extension cord or relocatable power tap.
ELECTRICAL: The Power Bars inside the laptop cart are only for charging laptop computers. Any other use may cause an
overload for the Power Management System, causing the “Brain” to shutdown, resulting in the LED lights flashing on and off.
To reset the Brain, turn off the main power switch, unplug the non-laptop computer, then turn the main switch back on.
CAUTION: Ventilation is critical for laptop computer carts to operate correctly, providing the appropriate airflow so that
heat-buildup is minimized during the battery-charging process, with the computers turned OFF. Be sure each laptop
computer is turned OFF before plugging into the cart.
CAUTION: Do Not block the ventilation holes on the cart. Proper air flow is required for safe operation of equipment.
CAUTION: Cart with computers should be keep in a room with a maximum temperature not to exceed 77° F or 25° C.
CAUTION: Maximum weight of accessories on top of cabinet is 25 pounds. Do not block ventilation holes when charging batteries.
CAUTION: Avoid loading equipment in the cart in a uneven fashion. Uneven weight distribution could cause a hazardous condition.
How Does a Laptop Computer Manage Heat?
To manage the heat stress of the battery, computer engineers include
sophisticated battery management functions in the design of the computers.
They can be found in two places: the external charger & internal to the
notebook computer itself. The transformer converts the alternating current
from the wall socket to a lower voltage direct current. Besides charging the
notebook’s battery these “bricks” as they’re sometimes called, can supply
enough electricity to operate the laptop and charge the battery
simultaneously.
Deep inside the computer a dedicated microcircuit continuously monitors
and manages the charging current, voltage and temperature of the battery.
If the temperature of the battery exceeds limits, the microcircuit will stop
charging the battery until the temperature drops to acceptable levels.
Keeping the battery cooler while charging allows the battery to charge faster.

Every laptop computer comes with 12 feet of cable, plus the adapter … 12 x 30 = 360 feet of cable that has to go somewhere!
Cable Management System … “The Cable Clutter Closet”
“A place for everything, and everything in its place.”
You know from personal experience the value of keeping your
closet neat and organized. You know exactly where everything is
when you open the door. So Bretford developed a “closet” for all
the cords and cables associated with Laptop Computers.
Your Intelligent Laptop Cart has its own “Cable Clutter
Closet” – a lockable compartment at the back of the cart
especially designed to keep all the cables away from the computers
and the hands that retrieve those computers from the cart.
The interior Divider Panel separates the cart so that 75% of
the cart is dedicated to the computers in the front and 25% is
dedicated to cables and power adapters in the back. Holes in the
Divider Panel allow the computer connector cables to pass thru and
be easily connected to the computers for charging.
By separating the computer from its power adapter, you minimize the amount of
heat beside the computer battery, allowing it to charge at a lower temperature,
… allowing the battery to charge faster.
(see “How Does a Laptop Computer Manage Heat?” above)
Only the IT Administrator has access to the Cable Clutter Closet, since
it has its own programmable Combination Padlock.
Fold-back doors for easy access and full view of the closet – you
immediately know if something is missing or out of place.
Special Cable Bins for the power adapters and their cables provide
nesting for cordsets.
Comes with appropriate stickers for color and number coding the
computers, the slots and the cable sets.
