  • Powers ThinkPad Yoga and IdeaPad models

90 W Square-Tip Adapter for ThinkPad & IdeaPad

This 90 W AC adapter delivers 20 V at 4.5 A through an 11 × 5.0 mm square connector. It fits a wide range of Lenovo ThinkPad Yoga, X-series, E-series, T-series, L-series, P-series, Helix, Chromebook and IdeaPad models listed in the compatibility data. The unit accepts 100–240 V input at 50/60 Hz for worldwide use.

Thermals, Noise and Power Draw

As an external power supply it has no internal fan, so operation is silent. The adapter converts mains power at up to 90 W output with built-in over-voltage, over-load, over-current and short-circuit protection. It is CE, FCC and RoHS certified for safe, efficient charging in normal use.

Replaces Original Lenovo 90 W, 65 W or 45 W Units

This adapter directly replaces Lenovo part numbers such as ADLX90NCC3A, ADLX90NDC3A, ADLX90NLC3A, PA-1900-72 and the 45N0xxx series. It also covers 65 W and 45 W models with the same 11 × 5.0 mm tip, so one unit can serve multiple ThinkPad and IdeaPad generations. The upgrade is worthwhile when the original charger is lost, damaged or when a single spare must cover several compatible laptops.

Questions about this item

How do I install the 11×5.0mm square tip connector on my ThinkPad Yoga 260?

Align the square tip with the charging port and push straight in until it seats firmly; the step people miss is checking that the 11×5.0mm interface matches exactly before applying force

What maintenance or replacement will this 90W adapter need over time?

The detachable AC cord can wear at the strain relief; replace the cord if the insulation cracks, while the brick itself has no user-serviceable parts

What limit appears first when this 20V 4.5A adapter runs continuously at full load?

Thermal protection engages if the brick overheats during sustained 90W output, causing temporary shutdown until it cools
