The 2008 world champion, still 11 points behind championship leader Rosberg despite winning two of the three grands prix in 2014, revealed that when the German arrived in Bahrain, he was handed a "big document".
"So I will do the same for the next round in China and hope I can capitalise," he added.
"I am going to study hard for the next two weeks and give it a lot of thought and digest a lot."
Hamilton finished just one second ahead of Rosberg in Bahrain, where the pair fought hard for victory despite team boss Paddy Lowe's radio call that they should "bring both cars home".
"It's great they allowed us to fight and didn't get in the way," said Hamilton.
But he warned that "if every single race is like that from now on, I can't always guarantee we'll both come out happy."
