It makes me mad that I have to hibernate my laptop (which is slow and often fails to work), just so as to swap in a new battery.
Today’s invention is a new system designed to help with a rapid hotswap…at least until battery technology makes its long-promised leap forward.
Laptops would be wired to take on board power for a short time when placed in sleep mode.
A portable USB mouse would incorporate a rechargeable AA battery (perhaps recharged continuously, using the mousewheel as a dynamo).
When your laptop charge is running out, you can activate sleep mode and just quickly swap out the main battery in the knowledge that your internal state will be preserved, using power automatically fed to it from the mouse.
