This may sound dumb but is there anyway to make a laptop charge itself ? At school we made a small circuit with an led , capacitor +more stuff and got the led to stay on for a few seconds after disconnecting the battery.

You do know what a capacitor does, dont you? Plus its an led, which takes such an insignificant amount of power.

You cant make it charge itself without some sort of energy. There is research happening on turning heat>sound>energy, which could extend your battery.. But your not going to see any commercial usage of this for awhile.

Just setup your power scheme, dont use vista on it, and plug it in when possible.

you would probably need a cap like for car audio or bigger to have it last and length of usable time.


i'm thinking a couple of these would be needed :)

what eveyone's try to say is that a cap holds a small charge for a little while after everything shuts off. thats why the led stay lit for a small time.
you would probably need a cap the size of a house to power a lap top for any amount of time. not to mention the initial load time of power consumption.

nope....not gonna happen

Ah ok lol.
