Is there an app, extension, or add-on that will disconnect laptop from Pandora.com after a set time?

Here’s a free program that says it will do what you want. You can schedule a shut down using this software. This is the search I used. It has a number of other options. These search terms bring up links for software that can close individual programs at a certain time.

Excellent, @wundayatta! I should have mentioned that the netbook I primary use has a linux operating system. I can use that free program on our windows laptop, though!

I’m pretty sure Pandora has a built-in function where it will stop playing if it doesn’t receive any input for awhile. The music stops and a screen pops up saying “are you still listening?” I don’t know how frequently they come up, though.

Thanks @xxii. That happens if you do not have Pandora One – their paid service.

There must be tons more, but you can also run the following command which is probably installed by default: sudo shutdown +30

That command will shutdown the computer in thirty minutes (change the 30 to another number to specify a different amount of minutes). Alternatively, you can run the following to have it shutdown at midnight: sudo shutdown 0:00

@Vincentt – thanks!. i tried sudo shutdown +5. it started the shutdown process but it did not finish. It did what i wanted though! i learned something – thanks so much. (maybe i need a different command besides sudo.)

I got it to work! sudo shutdown -h +30 (gotta add the -h). Woot!!

Great :) (And, I learned something too, thanks!)

@Vincentt i don’t think you were wrong. it worked for my (unusual?) version of linux. :-)

No wrong, but incomplete – adding -h is a better way to shutdown (little did I know that without it, the command shutdown didn’t actually shut down :P).
