Default usb charging on powerbook - 7100

Please Login to Remove!

Hello,

Has anyone else experienced extremely long charge times on their Powerbook with the 7100?

Also on one of my powerbooks when I plug it in the device claims that it does not have enough power to charge. I had it plugged in directly to the USB port on the side of the computer.

Normally for a BBerry to charge it requires drivers.... This is on the PC side of course so I guess the MAC allows otherwise?

Thats solely because the usb ports on the powerbook are low amperage. The lower the amperage, the higher the charge time. Your desktop however, has a solid 1-2 AMP rail on the powersupply, while the powerbook only puts out 350mA.. not even enough to spin a external hard drive.

Good point Guess. I forgot about the current on a laptop USB channel.
