Questions about this item

Will this 120 W adapter run a Lenovo IdeaPad Y400 or Y410P that still uses the original battery?

Yes, it is fully compatible with those models and meets the original 120 W specification, so it charges the original battery and powers the laptop normally.

How can I confirm the adapter is delivering power correctly once I plug it in?

The laptop charging indicator should light up and the battery icon in the OS will show it is charging; the adapter also includes over-current, over-voltage and short-circuit protection that operates automatically.

Does the package include both the power brick and the mains cable, or must I buy a cord separately?

The adapter comes with a total 10 ft power cord already attached, so no separate mains cable is required.
