The Reader may not turn on, or it may appear to be frozen if the unit needs to be reset, the battery is completely discharged or moisture condensation has occurred.
Please perform the below mentioned steps and check whether it helps.
Because each of these steps represents a possible solution to this issue, check the Reader status after completing each step.

1. Connect the Reader to a USB connection or optional AC adapter. Allow approximately 5 min for it to turn on. If it does not turn on automatically, try to turn it on again. If it still does not turn on, continue with the rest of this procedure.
2. Perform a soft reset. Just press the RESET button using a sharp-pointed object
3. After the RESET button has been pressed, slide the POWER switch to activate the Reader again. If the Indicator light next to the power button on the Reader is yellow , the unit is attempting to start up. If this is the case, allow it a few moments to complete startup.
4. If startup did not complete, connect the Reader to the computer or optional AC adapter and perform a soft reset again.
5. Disconnect the Reader from the computer (if applicable) and then slide the POWER switch to activate the Reader. Check if the Indicator light next to the power switch on the Reader is yellow (indicating it is turning on) and if the unit is responding.
6. If the unit is not responding but Starting up... is displayed on the screen, attempt a hard reset.
7. If the unit is still frozen, connect it again to the computer or optional AC adapter and while connected, check if the Indicator light next to the power switch on the reader is red . If this light is red , allow the Reader to charge for one hour so there is sufficient charge for troubleshooting.

* If your computer goes into hibernation or sleep mode, charging will stop and the red charge indicator on the Reader will turn off.
* It is recommended to charge the Reader while you are using the computer or to adjust your sleep/hibernation settings of your computer to avoid any interruption in the charging process. You also can use the optional AC Adapter model ACS-5220E.
8. Once the Reader has sufficient charge, perform these troubleshooting steps again.
9. Under certain circumstances, moisture condensation can occur. Moisture condensation can be caused by moving the Reader between temperature extremes or if the Reader has come in direct contact with moisture. If you suspect moisture as the cause, allow the Reader to sit for a few hours before attempting to turn it back on.

General notes regarding the battery status:
* You can verify the charge status by disconnecting the Reader from the computer and checking the battery indicator. The battery indicator will display 4 black bars when it is fully charged.
* It will take approximately 4 hours to achieve a full charge with a computer. It will take approximately 2 hours to achieve a full charge with the optional AC Adapter.

If the issue still persists, service of the Reader is required. Please follow the below link to get it repaired:

The most common cause is a flat battery. There is a trick to charging the battery in these small mp3 players. It wont charge if it is turned on, and it won't charges if it's turned off. Here what to do...
1. plug the payer into your USB port. or wall charger
2. switch thje palyer on using the mechanical switch (on the side)
3. turn it off by either holding down the play button, or selecting "System" from the menu
4. The screen will go black and the battery will begin charging.

make sure the connectors at the batteries are not loose and battery fuse is plugged in all the way

The Transport T2300 has an internal battery that will run the laptop for several minutes after the main battery goes dead. This feature allows you to save your work and shut down safely. If you run the laptop until both batteries are dead, even a brand new battery can't start the unit again. You have to follow this procedure:
1.Unplug power cord

2. Remove any attached periphal components including the cd rom and/or floppy disk module if you have one. Both remove with a push button switch located on the bottom of the unit.

3. Plug in power cord and charge the unit for a minimum of 24 hours straight. 30 hours is better. This whole time will be spent slowly recharging the internal back up battery.

4. Once that is done, unplug power cord again and reinstall any floppy/cd drives. Plug power cord back in now and charge for at least 24 hours again.

If your backup battery is dead, you can't charge the main battery or turn the unit on. The longer you charge, the better. We had one unit here that had to be on the initial battery backup for 72 hours before it finally took hold. Then, one overnight recharge on the regular battery and all was well.
If you need drivers or manuals for the 2300, all are available on cd at [email protected] for around $9.50 including shipping, handling, and owners manual

Try giving it a full charge. I used different model Tom Tom that would not turn on even if plugged in until after the battery was recharged.

check the battery switch on the back. you will need a pen. Mine does the same thing. I believe this switch has to be set to ON for it to work. At least mine wont turn on unless the switch is turned on.
