I have a Garmin Nuvi 255WT. I turned off the GPS and connected it to
my PC with a USB cable. The screen is dark and says: "Charging
battery. Slide the power key to turn on". But 24 hours has past. It is
still the same message.

Thanks.

HUH ? - with the USB cable connected, it usually powers up in "computer
mode"
with the screen showing a computer image....

Your description is normally what I see with the Garmin 12v DC special car
charger ?

Are you using the 'right' USB cable? The garmin one had a resistor
connected between the live and one of the earth lines (which I assume is
disconnected at the computer end) and the device won't switch to the
correct mode without this signal voltage.

That is normal, my 750 always says it's charging the battery any time
the unit is turned off while external power is applied. It doesn't
really keep charging the battery but it does monitor the battery's
state of charge. I think it will switch back and forth between charge
and monitor as needed.

I am using a USB cable for digital camera. My notebook PC is always on
except that it may be in standby node sometime. But even at standby
mode, the GPS still shows that the battery is being charged.
After the battery is full, will it show a message like: "Battery is
fully charged"?

Thanks.

Very Weird -
Using all our USB cables laying around from cameras, etc -
they all work the same way.... on our 255, and 260...
with the GPS going into "computer connected mode" vs your Car Charger mode

Do you have any other USB cables to try ?
I'm guessing that you don't see the GPS as a flash drive on your computer ?

Lastly - since I only see that message when using the Garmin 12v DC car
charger,
have not really seen a "charging complete" - just the dark screen "charging"
message.

I can't remember there being any indication that charging is complete - I
tend to do all my charging while in use in the car. I think the only way
you can find the state of the battery charge is to disconnect from the
usb cable, and when the unit starts up the charge indicator is shown on
one of the first screens.

On my Nuvi 760, I don't see any battery information during startup,
but of course there's the 'secret' screen reached by pressing and
holding the battery icon for several seconds. There you can see the
battery capacity expressed as a percentage as well as actual voltage.

I think he meant the Battery Icon up in the corner,
as on some models, the GPS auto-flips into map mode after a minute or so...
I think my 255 does, but my 260 doesn't
