My Kindle Fire will not start


If you last charged it with the computer USB port, try charging with the supplied AC adapter instead. If you last charged with the computer USB port, try charging with the AC adapter this time. This will help isolate a bad AC adapter / power cord or USB cable / USB port.

It is important to note that if you are charging your Kindle via USB port on a computer, when many computer enters "sleep mode" the USB power is shut off at this time too. Charging is effectively halted - even though still connected. You should only expect to charge while the computer is active or when using the AC adapter.

You can also purchase an aftermarket DC charger. These are small plugs that are inserted into your auto's port or cigar lighter. They provide 1 or 2 USB connectors to plug in a USB cable. These devices are suitable to supply / charge just about any devices that uses a computer's USB port to power / charge a device. They cost anywhere from $5 and up and look something like this:

Will only operate when plugged in to the mains adapter


Hi angelahar313,

You can try to reset the unit and recharge it again.

This operation will not affect your ebooks:

1. Leave the unit connected to the adapter
2. Hit the reset at the bottom for 3 seconds
3. Slide the power switch (the screen will blink and boot up)

If after that the proble still persist, you can try a hard reset. NOTE: This will set the reader to factory settings and will delete all you content.

1. With the unit connected to the AC Adapter, hit the reset button at the bottom for 3 seconds
2. Slide the power switch
3. While the reader shows "Opening Book" press and hold the "0" button and the directional down arrow at the same time, until " Reset All" appears on the screen
4. Press number 5 to confirm and turn the unit back on
5. Try recharge unit and disconnect it and see if that works

If these steps do not work, then contact Sony to get the unit repaired.

GoodLuck!

My Sony PRS600 does not fully charge. I had it


First, confirm whether you're using the AC-S5220EAC Adaptor to charge the Reader, as it's always recommended to use that one with the Sony Reader. However, you may also keep connected the Reader to the Computer for at least 4 hours to get it fully charged. If the issue still persist, perform a soft reset. To soft reset, please press the RESET button using a sharp-pointed object. Then, try charging it. That should resolve the issue.

The USB connected screen is frozen on my reader and I don't know how to fix it.


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: http://eservice.sony.com

The PC is not switching on


Without know exactly what already you tried to powered it on, I can only especulate on all the possible reasons, so let go one by one throuh them and their possible solutions:
1. The RX3000 Ipaq family has a known mechanical issue on the switch that senses when the back cover lid is properly closed.

When the switch is nor properly depressed, the PDA won't charge the battery if plugged on the cradle or to the USB sync cable, or won't turn on.

Remove the back cover lid and the battery, put them back again. Check the cover lid is placed flush and that there is not any gap between the cover and the PDA body.

Try again in power it on and/or charge the battery, confirming the orange LED light is turning on.

2. Either the cradle/USB sync cable or the AC wall adapter are defective.

The PDA won't power on if the battery is not charged to the minimum voltage for it. If the AC wall adapter or the cable/Cradle are defective, won't power on.

Put to charge the battery and confirm the orange LED light is turning on. If so, the you can discard that the cradle/USB cable or AC wall adapter are defective.

It the orange LED light won't turn on, it may be either one of these three parts that are defective, or that the back cover lid is not properly closed.

3. The battery dried out. If the battery is defective or won't accept charge, the pda won't power on.

To discard a defective battery, put the PDA to charge it, and it will power on when plugged to the USB cable or to the charger, and check in the settings screen, on the power icon, if the battery is charging.

If the back cover lid is properly placed, and the PDA won't power on when plugged to the USB cable or AC wall adapter, then the battery is not the problem.

4. Discarding that the battery or the USB cable or cradle or the back cover lid are the problem for this problem, the only option that is left is that the main board is defective.

Such failure on the mainboard could be caused for several reasons (moisture or humidity or water damage, or a electronic component that is worn out, or a integrated circuit that is shorted, etc) but it can be only verified and confirmed by an electronics technician.

You have the option of send it to be repaired, or try it yourself, which will require to buy a PDA with working mainboard (or the mainboard alone) and swap the parts. It requires a minimum of technical skills to do it.
