The ThinkPad 90W AC Adapter (Slim Tip) from Lenovo provides convenient access to power wherever a wall outlet is available. Useful as a spare or extra charger, you can keep one at home, one at your office, and one in your bag. Simply plug it into a wall outlet to deliver AC power to your compatible Lenovo laptop and recharge the system battery. This adapter will perform to the same standards as the one that originally came with your laptop.
This adapter is not compatible with legacy notebook systems with a round, barrel-type power plug.
