Plug the USB cable into a 5 V wall adapter or a powered computer port that can deliver at least 500 mA. A flashing battery icon in the status bar tells you charging is underway, and a full charge from empty usually takes about four hours. ### How long does a TI-84 Plus CE take to charge? Roughly four hours from empty to full on a stable 5 V USB source. A lot of students just leave it charging overnight before SAT or ACT morning. ### Can I charge my TI-84 Plus CE from my laptop? You can, as long as you use a powered USB port and keep the laptop awake if it tends to sleep. Skip unpowered hubs though, since they often drop below 500 mA and will not charge the calculator properly. ### What does the orange charging light mean? On some cables and docks, orange means it is charging and green means it is done. If your setup has no LED at all, just trust the battery icon in the calculator status bar instead. ### How do I know if my TI-84 Plus CE is charging? Check the top status bar for a flashing battery icon while it is plugged in. A solid full icon means you are good to go, and an empty one is your cue to charge before test day. ### What if Validating OS blocks charging? Hold the reset button on the back for about two seconds, then reconnect a stronger adapter rated at 500 mA or more. If that does not clear it, the [complete TI-84 guide](https://shoutingnow.com/guides/ti-84-plus-ce-guide/) and [reset tutorial](https://shoutingnow.com/blog/ti-84-plus-ce-reset-tutorial/) cover the rest of the troubleshooting. ### Can I use the calculator online while the CE charges?
