Iconia w4 EE6 power board, not charging

I have the Iconia W4 820, Model: EE6. It wont take a charge, but i opened it up easily enough and found that the power/headphone chip comes out easily enough. Where can i get a part number for this chip? I already went though acer and the numbers they gave me arent showing up anywhere. Help?
