I charge my sony eric. tm506 and sometimes it'll have the symbol for charging but I notice the battery is going down! Later on I'll try charging it, and it won't charge at all. The symbol won't even appear. Any suggestions? I've had this since about...May / June and now around September I started getting the problem.

Your question was posted under the Nuvi 680 GPS, so I am assuming this is the model that you have.
On the main screen, you will see a green battery status indicator in the upper right-hand corner of the screen. The battery is divided into 4 parts. Each part represents 1/4 power. So if you have one green bar, that indicates that the battery has 1/4 of power left. If there are 3 bars, that indicates that there is 3/4 power left.
When the unit is charging, you will see a yellow lightning bolt appear over the green battery status icon.
When the lightning bolt is not there, this means the unit is running off of the battery.
When leaving the unit to charge, press and hold the power button until you see that the screen says Charging Battery. A few seconds later, the screen will go blank to save energy.
Pressing the screen again later will either say Charging Battery or Battery Charge Complete.
If the recharageable battery is more than 3 - 4 years old then the battery could be worn out.Rechargeable batteries have a finite number of charge and discharge cycles andwill lose their charge capacity over time, i.e. won't charge to 100% and graduallythe charge reduces until the battery won't charge up at all. OR The batteryshows a 100% charge but when the adapter is disconnected the battery drops offto zero capacity in a very short time. If the battery drops to an unacceptablecharge level then the battery needs to be replaced.
My guess is that with the age of the battery it isn't able to hold a charge anymore which means you'll need to purchase a new battery. Your best bet for that will be to go through Sony or the website Dr. Battery.
Okay what happens sometimes is the charger gets into a feed back loop. What to do is remove the battery unplug the charger wait a few seconds (Maybe 20/30) plug the charger back into the outlet and then put the battery back in the charger. It should start to charge again and a few minutes later go to the blinking for full charge green.
It'll happen the other way as well meaning if the battery gets a memory (they say they don't but they do) you need to unplug the battery let is sit till it's cool and put it back on charge again. I've had this problem many times and have put it on charge and back off several times with in 15 minutes before it started to charge as it should.
Also these batteries do have a life span and if it's a three year old battery with many charges it could be failing meaning it just won't take a full charge.
It seems that the issues is with the battery itself, not the cppu.
To double check, you can do the following:
1. Disconnect adapter and run battery completely dead. 2. Reconnect adapter and let charge for at leasst 12 hours OR until battery displays 100% charge.
If it still won't charge to 100%, then you know for sure the battery is defective/worn out.. If you want to know more about this, look on wikipedia for: "Laptop Battery Lifespan" or "Laptop Battery Memory Charging".
But I'd say it's safe to assume that it's time for a new replacement battery for your Notebook PC.
It's either the charging port is bad which means you have to get a universal or desktop charger to charge the battery or take it to a technician OR the battery is bad and you have to buy a new one. GOODLUCK
