|Here's an interesting problem.|
My laptop is not turning on / charging the battery unless there is something plugged into a USB port (in this case the external hard drive). My charger is fine, I've tried it on another laptop.
At the moment I have a IDE hard drive being powered by my desktop with a USB cable attached so it can be used as a external HD.
At this very moment, I've taken the battery out of the laptop and have it running on external power. If I take the USB cable out of the laptop . . . . the laptop will die.
