Okay, so is it going to fuck up my laptop if I used a 19V 3.16A ac adapter versus the 19V 3.95A adapter it's supposed to use?

If so, why?

Laptop should be fine. I'm guessing this will work without a hitch.

If there was a problem most likely the adapter will go like ^ said. I doubt the laptop will draw the max amperage all the time.

my apple charger gets hot as hell when i charge my powerbook up from near-dead charge, almost too hot to touch. im guessing what happened to yours is okay... just keep an eye on it. if it's designed well, the fuse will blow before anything bad happens.

^^ don't worry about it

Except that those 6 60 watt bulbs aren't running on 19v DC

^^It was way beyond the normal temperature. I know what a power brick is supposed to feel like. It was on the verge of melting the casing into the carpet hot.

d00ds

The adapter gets very hot if your battery is drained out because the large potential difference causes a lot of current to flow. More current means a hotter transformer core.

d00d: it gets danerously hot because it was trying to charge the battery WHILE powering the laptop as I was using it. The combination was what put it in dangerzone. Just charging it was fine.

4A that's what, 360W?

or maybe it's 320, depending on your IP address.
