Replacement 135W Adapter for Lenovo Y50-70
This 135W AC adapter replaces Lenovo part numbers 45N0368 45N0485 45N0486 45N0501 45N0502 4X20E50558 4X20E50559. It suits owners of a Lenovo Y50-70 who need a new power supply rated at 20V 6.75A. Buyers whose laptop requires a 170W or 230W unit cannot use this model.
Installation and common issues
The package includes a UL listed 3-prong AC cord of 6 ft and a 6 ft DC cord, giving ample reach without extra extensions. A slim plug tip fits the Y50-70 charging port; verify the tip profile before connecting. The adapter case resists water and humidity, reducing risk of damage from spills.
Deciding specification — 135W output
The single figure that decides fitment is the 135W output at 20V 6.75A. If the original charger is rated 90W this adapter will still operate, but a 170W or 230W requirement means this unit is insufficient. Match the wattage on the old brick to this rating before purchase.
