I ordered a Casio Casiopeia E-125 from Ebay. I noticed after I bought it that it said it needed a new battery. I ordered one. Then I took out the holder for it and noticed the cord on it. Is this a USB port? How do I charge the unit? Do I plug it into something on my main computer and if so what?

leave the backup battery in the PDA and bring it back to life with this how to ;)
if that doesn't help you may need to give the battery a little kick-charge for the PDA to recognize it again. the PDA "thinks" there's not battery if the battery voltage is below 2Volt. to "kick-charge" the battery just get a AC adaptor with at least 5V and 1A (a.k.a. 1000mA) with 2 wires and connect them to the battery pins (with "+" and "-" correct!)
if you have your PDA lying in front of you with the display down and the battery cover opened, the pins of the battery are as following:
left: plus middle: charging/temperature (not important for hand-charging) right: minus
connect the wires of the AC adaptor correctly and let it "kick-charge" for about 5minutes (but NEVER let it charge any longer if the battery is getting hot!!!!)
after that, the PDA should recognize the battery again because the voltage is more than 3Volt again.
but don't (!) try to power it up after kick-charging! the batterys voltage is higher than 3Volt again, but it takes just a few seconds to empty it again if u try that. it's only for the PDA to "see" the battery again ;)
I had the same problem with an E125 which I brought off eBay that hadn't been used for several months.
I took out the backup battery and put the main battery in it's holder with a bare wire held onto the negative & positive terminals. When I turned on the charger, I held the other end of the bare wires onto a partly charged Nokia Battery (Also 3.7V internal). The current from this battery was enough to let the Casio start charging. After two minutes I disconnected the Nokia battery and gently tugged the bared wires free. The Casio kept on charging happily. After six hours I disconnected the AC charger, installed a new backup battery CR2032, and everything was go.
The Casio PDAs will quit charging very quickly if the battery is very, very discharged. If you continue to remove and re-insert the charger into the PDA's power socket, the recharging cycle will last longer and longer until finally the stupid thing will fully recharge its battery.
I have two Casio PDA's and three batteries that were recovered after a bit of tedious struggle to force the charging cycle to complete.
There is reset and hard reset on many units, did you do both. You might try pulling the battery out for an hour or two and try it.
Other than that open the back and look for dead bugs :-) actually not much you can do inside unless you have a parts source and Casio units are kind of like without parts - I emailed for some two weeks ago and never did hear from them - which is normal - it has happened numerous times before on other subjects including parts.
Blinking amber light means the battery is not fully recharged. Once it is charged, press the power button. If the the device still does not turn on take out the main battery and the backup battery. Put the main battery in first, then the backup battery and put the battery switch in the lock position. Press the power button and you should see initializing memory..., then starting..., then it will ask you to set up the device.
You will need 2 things.
Software to load on your E-125. The included Cd with your Nokia should have it.
You will need a special cable to connect Nokia to E-125. I don't know where you will find it easily.
There is a firm in Finland which makes all kinds of cables to connect different models of Cassiopeias to different models of mobile phones - essentially Siemens, Nokia & Ericsson. They run about US$ 50/=
Last time I saw their listing it was 4 pages long. You might have to do some searching on the net or contact Casio for information.
Hope this helps.
Unless a Casio technician has looked at it don't take Casio's word for it.
There is an inverter PCB which converts the DC to high frequency AC for the fluorescent back light. lamp. This is available & can be repaired / replaced.
There is also an issue with the E-125 backlighting which simply requires resoldering of a connector on the main pcb.
Then there is the fluorescent lamp itself which can go bad & may be replaced.
So DO take your device to a well equipped competent technician to look for the precise problem.
This is what I suggest:
Get yourself a new backup battery.
First backup your Casio.
Then install the main battery.
Plug the Casio in and recharge overnight.
Once recharged, install the new backup battery.
Make sure you do not touch the battery with your hands.
Use a tissue.
This should solve your problem if the Casio is not physically
