☑️ Key Features

⚙️ Fit Notes

• Confirm your device uses the Slim Tip (yellow rectangular) connector before ordering (USB-C is different).
• Your original charger wattage may be 45W, 65W, or 90W — this 90W version is commonly used as a replacement as long as the connector and output (20V) match.
• If your system originally shipped with a lower-watt adapter, using 90W is typically fine because the laptop draws only what it needs, but you should still match the exact connector style and voltage.

Common lower-watt Slim Tip replacements (for reference):

• 65W: 0A36264, 45N0278, 45N0258, 45N0261, 0A36266, 4ZX20E75085, SA10J20099, SA10J20149, 0A36261, 45N0262, 45N0253, SA10J20098, ADLX65NCC3A, ADLX65NDC2A
• 45W: ADLX45NCC3A, ADLX45NLC3, 36200606, 36200280, 36200247, ADLX45NDC3A, 45N0289, 45N0293, 45N0294, 54Y8998, PA-1450-18, ADLX45DLC3A, ADLX45NDC2A, ADLX45NLC3A
