My Lenovo says ‘plugged in, not charging’ — battery or charger?

Lenovo “plugged in, not charging” is often caused by settings (Vantage charging threshold) or power delivery (USB-C charger wattage). A worn battery is possible—but confirm first.

Step 1: Check Lenovo Vantage charging threshold

• If conservation mode is on, charging may pause at a set percentage.
• This is normal and can look like a charging fault.

Step 2: Confirm charger wattage and port

• For USB-C models, use a charger with sufficient wattage for your laptop.
• Under heavy load (gaming/compiling/video), a weak charger may not increase battery %.
• Try another known-good charger/port if available.

Step 3: Check battery health

If Full Charge Capacity is much lower than Design Capacity and you also see sudden drops/shutdowns, replacement is usually justified.

What to buy if needed

• Battery: match FRU/Part Number, V/Wh, connector.
• Charger: match connector type (USB-C / Slim Tip / round) and wattage.
