[speculation]
If your laptop is able to play Oblivion I would assume that it can play Skyrim. Bethesda is going from consoles to PC and since it is developing Skyrim for the same consoles as Oblivion it *should* have similar specs. So, if they do a halfway decent job of optimization you should be able to run it fine. [/speculation]
I actually rather doubt that. The consoles had performance issues with Oblivion, yes, but that's because Gamebryo svcked. In reality, the 360 and PS3 are rather powerful machines that can handle visuals far more advanced than Oblivion's so long as the engine is optimized well for console use (As was
not the case with Oblivion). Skyrim runs much more smoothly, but likely demands far more than Oblivion did (Better performance, but still a far more technically advanced game), so a PC that can handle the previous game is in no way guaranteed solid performance. If I'm wrong, I'll eat my hat.
Edit: Simply put, Oblivion's performance was awful because of its engine, but that does not mean a better optimized engine five years later will run better on a machine that runs Oblivion (Unless, of course, you're running a monster machine with Oblivion, but this is more focused on somebody with a machine that can
just handle Oblivion). It would probably run even worse, actually.
