Charging your TI-84 Plus CE™handheldusing acomputer
The TI-84 Plus CE™ handheld can be charged from a computer. TI-SmartView
CE or TI-Connect CE computer software must be installed prior to connecting
the handheld to ensure the appropriate drivers are installed. Power
management controls on some computers may prevent continuous charge via
the USB port. Stand-by and sleep modes on laptop computers typically
terminate USB connectivity to conserve power. In some cases this can be
adjusted through the device manager:
•Install the TI-SmartView CE or TI-Connect CE software
before connecting the handheld to the computer.
•Once the software is installed connect your handheld to the
computer using the USB cable provided.
•Check the connectivity between the handheld and the computer.
A simple way to do this is using the screen capture tool in the
TI-Connect software
Note: When capturing a screen from the handheld make sure the
handheld is connected and selected. (Shown opposite)
Another option for checking connectivity between the computer and handheld is the
Device Manager (Windows®) or System Profiler (Mac®). Locate and expand the
Universal Serial Bus controllers and select: TI-84 Plus CE™ Handheld Device.

Charging your TI-84 Plus CE™handhelds using the TI-84 Plus CE™
Wall Adapter
The TI-84 Plus CE™ Wall Adapter (not supplied) can be used to charge the TI-84 Plus
CE™ handhelds. The TI-84 Plus CE™ Wall Adapter provides a USB outlet and is
connected to the handheld via the USB computer-to-handheld cable.

where multiple handhelds require charging. Information about charge and
status is indicated by the LEDs on the side of TI-84 Plus CE™ handhelds.

Charging Troubleshooting for TI-84 Plus CE™handhelds
The most common error when attempting to charge the TI Rechargeable Battery is via a
computer. Termination of power supply to the USB port due to the computer or computer
settings prevents the handheld unit from charging. Charging the TI-84 Plus CE™
handheld for the first time takes between 4 and 6 hours, thereafter charge time depends
largely on the status prior to charging.
If charging from a computer does not produce the desired result try:
•Using the approved TI-84 Plus CE™ Wall Adapter
•Resetting the handheld device using the reset button on the reverse.

TI Rechargeable Battery maintenance for TI-84 Plus CE™handhelds
Lithium-ion batteries have a limited life, which is affected by several factors: environment, storage, the
number of charge/discharge cycles, and level of discharge/charge. To extend the TI Rechargeable
Battery lifespan and battery life, we recommend following these simple guidelines:
1. Avoid heat and humidity:
•TI Rechargeable Battery is designed to operate optimally at room temperature.
•Heat can reduce lithium-ion battery life.
•High humidity environments should be avoided.
2. Usage and Charging:
•As lithium-ion batteries age, they lose capacity. When properly maintained and under normal
usage, batteries are expected to last at least several years.
•If you use the TI-84 Plus CE™ handheld regularly, recharge the TI Rechargeable Battery
often. Avoid waiting until it is fully discharged.
•If you do not use the TI-84 Plus CE™ handheld regularly, fully recharge the TI Rechargeable
Battery at least once per month.
•Do not leave the TI-84 Plus CE™ handheld connected to a charging device for longer than 3
days.
•Use only TI Rechargeable Battery approved for the TI-84 Plus CE™ handhelds.
•Use only charging devices approved for the TI-84 Plus CE™ handhelds.
3. Recommendations for storing TI-84 Plus CE™ handhelds with lithium-ion TI Rechargeable Battery
for 3 months or longer:
•The best temperature for proper care and storage of lithium-ion batteries is between 0–25°
•Extended storage can cause batteries to discharge deeply, which can deteriorate the lithium-
ion cell and reduce the TI Rechargeable Battery capacity, service life and ability to recharge. It
is recommended the TI Rechargeable Battery be fully charged before putting the handheld in
extended storage and that it be recharged fully every three months while in storage.
4. Update your TI-84 Plus CE™ handheld Operating System (OS) as new updates become
available. OS updates may contain new programs to optimize TI Rechargeable Battery life.
