Can i charge the battery from usb cable into pc

This camera does not charge via the USB cable, the cable is used to download the photos to the computer.
This camera uses a recharageable lithium battery and the battery needs to be removed and connected to an external battery charger to be charged.

TRANSFERRING PHOTOS TO COMPUTER
If your photos are stored on the memory card, then removethe memory card from the camera and insert it into an USB memory card reader.Connect this USB memory card reader and memory card into the USB port of yourworking computer. Your computer will see this as an USB Mass Storage Device oran external storage device, you can then open the folder on the memory card andcopy the photos to your computer.

You can't charge the A80 by plugging in a USB cable. The cable is for downloading photos only. Assuming that you are using rechargeable AA batteries, you need to remove the batteries and place them in an external charger to recharge them.

Use the USB cord to charge the camera. Just make sure you're connected directly to a powered USB port, not going through a hub.


The best way to download pictures from your camera to your computer involves removing the memory card from the camera and plugging it into a card reader (either built-in to the computer or connected via USB or FireWire). This is likely to be faster than connecting the camera to the computer, and won't run down your camera's batteries.


Once the card is plugged in, it will appear to your computer as a removable drive. You can use the operating system's drag&drop facility to copy pictures from the card to the computer's hard drive, the same way you copy any other files. Or you can use any photo cataloging program.

Does this mean it's charging

The above links have firmware updates, as well as, the general viewing and processing software of your camera.

check the usb cable. (try different cable if there's any)

OR

try to connect the cable to different usb ports.

OR

try re-installing software/drivers.

I charge my phone (which is a Motorola) all the time with the USB cord. If you have the driver for your phone installed on your computer, it should work =)

Well it does, I don't know what had happen to your cable but mine works...it automatically charges my phone every time I connects the cable to my PC.
There might be something wrong with your cable's charging capability or with your phones charging port.
Try to look for some switches if there is. But I think the problem is your Data cable's capability to charge.

How did you get it to download to your Mac are using Mac OS X.5?  I am using 10.5 and the program just quits on me... I have not been able to download any pics at all. 
Thanks for your help.
