AC adapter for Lenovo all-in-ones

This 150 W power supply delivers 19.5 V at 7.7 A through a 6.3 mm by 3.0 mm barrel connector. It replaces Lenovo part numbers ADP-150NB D, 36001875, SA10A33627, 54Y8910 and PA-1151-11VA. The unit accepts 100 to 240 V AC input at 50 or 60 Hz for worldwide use. A 10 ft total cord length provides flexible placement.

Buyers replacing a failed original charger

The adapter suits owners of compatible Lenovo A700 and A720 systems who need a direct replacement with identical voltage, current and connector dimensions. It is not for users whose laptops require a different output voltage, a higher wattage rating or a USB-C power interface. Builders looking for a multi-voltage travel charger or a unit with detachable cables should consider other options.

Straightforward plug-in installation

Connect the AC cord to the brick, plug the barrel into the computer and attach the mains lead to a wall socket. No drivers or configuration are required. The main issues arise when the tip size is mismatched or when the device demands more than 150 W, causing the overload protection to trip. Verify the connector dimensions and power rating before purchase.

Questions about this item

Which laptop models are confirmed to work with this 19.5V 7.7A 150W 6.3x3.0mm adapter?

It is listed as a replacement for Lenovo A700, A720 and part numbers ADP-150NB D, 36001875, SA10A33627, 54Y8910 and PA-1151-11VA.

Can I use this 150W adapter on a laptop that originally shipped with a lower-wattage 19.5V supply?

Yes, the higher 150W rating means it can deliver up to that power; the laptop will only draw what it needs at 19.5V.

How do I verify the adapter is operating correctly once connected?

The laptop should show it is charging, the output voltage should measure 19.5V and the unit should stay cool during normal use.
