<human>: Summarize the given text in a few sentences.

A while back I bought a Unibody Macbook Pro. It comes with the option to run on either an integrated graphics card (slower but longer battery), or a dedicated card. I ran it exclusively on the dedicated card right up until my battery died.

Brought it in to the Apple store and they said that the battery was rated for lasting 300 power cycles and mine lasted 240, but since it wasn't under warranty any more I had to pay $130 for a new battery.

I bought the battery and switched to the integrated graphics card hoping to slow the new battery's degradation. That's when I found that my Macbook Pro, like many others, has a defect with the integrated graphics card where the screen black's out in strips every few seconds, making the energy saver mode completely non-viable for use (programming with this going on is horribly distracting). This is [what the flickering looks like] And here's a [thread with 1224 replies] of people talking about the issue.

I took it back in to the Apple store to show them the problem, and they said that since it's not under warranty it would cost $310 to have the problem fixed. I'm trying not to be an over-entitled American and accept that.. but $310 to fix a known defect seems kind of ridiculous. Especially when this is Apple we're talking about.
<bot>: I just found out that my Macbook Pro has had a manufacturer defect, but it's no longer under warranty and Apple says it will cost $310 to repair. What can I do?
