I have a 2008 Macbook Pro and my cat recently chew through that power cord. I bought a 85w adpater but I don't want to open it if I know it won't work.
Does an 85w work with a 2008 Macbook pro or should I exchange it for the 60w?
According to Apple knowledge base entry HT2346 the 85W power adapter is the right one. However, there seem to be issue with "T" style (the old) vs. "L" style (the new): see this thread. It seems that for some people, a workaround does the trick:
If that doesn't work, you need to call Apple support to arrange for your power adapter to be replaced with a "T" style adapter:
Edit: Apparently the MacBook SMC Firmware Update 1.4 should fix the "L" style power adapter issue on older MacBooks.
Yes. All MacBook Pro 2008 Models can use an 85W Apple Magsafe power adapter.
This information is available from Mactracker, an app that catalogs details on every Apple product.

I have no connection to the developers of Mactracker, it is just an indispensable tool that I have used for years to identify hardware details on non-current Mac models.
I hope this helps.
It actually depends on your screen size.
