Important Part-Number Note

40Y7696 has been removed from the compatibility list. Lenovo's support documentation identifies 40Y7696 as a ThinkPad 65W ultraportable AC adapter marketing part number, so it conflicts with this listing's 90W, 19V/4.74A specification.

Compatible Laptop Models

Online replacement listings associate this 90W adapter family with various Lenovo IdeaPad and IBM/ThinkPad models, but the exact models for this physical unit have not been independently confirmed. Check the laptop's required voltage/current and original adapter part number before ordering.

Before Ordering

Use only when the laptop requires 19V, up to 4.74A, 90W and the same 5.5mm x 2.5mm connector. Do not select by brand or part number alone.
