Power for ThinkPad P40 Yoga

This 45W and 65W AC adapter replaces the original charger for the Lenovo ThinkPad P40 Yoga. It matches part numbers SA10J20148, 0B56097, 42T5044, 42T5035, 42T5050, 42T5065, 42T5083, 445N0437, 42T5077, 42T5071, 42T5017, 42T5174, 20GQ and 20GR. The unit is new and built with high-quality components.

Worldwide input with long reach

The adapter accepts 100-240VAC at 50/60Hz for global use. A 10 ft power cord gives flexibility in outlet placement. Safety features include over-current, over-voltage, short-circuit and total-power protection. FCC, CE and RoHS certifications confirm compliance.

Direct replacement for worn or lost chargers

This unit restores charging when the factory adapter fails, is lost or shows cable damage. It is not for buyers who need a higher-wattage supply for other ThinkPad models or a USB-C power delivery solution. The jump is worth it when the original 45W or 65W charger no longer delivers reliable power.

Questions about this item

What is the maximum power this adapter can deliver before its protection circuits engage?

The adapter is rated for 65 W output, with built-in over-current, over-voltage and short-circuit protection that will limit power if that threshold is exceeded.

How much heat or fan noise should I expect when the charger runs continuously?

The unit has no fan; it relies on passive cooling and over-heating protection, so it stays silent and only becomes warm to the touch under full load.

Which Lenovo part numbers does this charger replace so I can confirm it fits my existing ThinkPad?

It replaces Lenovo part numbers including 42T5017, 42T5035, 42T5044, 42T5050, 42T5065, 42T5071, 42T5077, 42T5083, 445N0437, SA10J20148, 0B56097 and S0B56097.
