Which HP laptops use the blue smart pin?
Most recent HP Pavilion, ProBook and 15s barrel-charging models use the blue smart pin. Confirm by the pin on your existing HP adapter or the port on the laptop.
HP Laptop Chargers & Adapters (45W, 65W, Type-C, Smart Pin)
HP uses a blue “smart pin” barrel connector on many models and USB-C on newer ones, in 45W and 65W ratings (higher for Omen/gaming). The blue smart pin and the older yellow pin are different, so match HP’s connector and wattage from your original adapter label.
These HP chargers list wattage, output and connector. If your HP runs only on AC and will not charge, confirm the adapter rating here before buying.

Frequently asked questions
Is a 65W HP charger okay for a 45W HP laptop?
Yes, as long as the connector matches. A 65W HP adapter safely runs a 45W HP laptop and charges a little faster under load.
How do I know my laptop charger wattage?
Read the original adapter’s label. It shows output like “19.5V 3.34A” — multiply volts by amps to get watts (here ~65W). Buy the same wattage or higher, never lower, and keep the same voltage and pin type.
Can I use a higher-wattage charger safely?
Yes, if the voltage and connector match. A 90W charger on a laptop that came with 65W is safe — the laptop only draws what it needs. A lower-wattage charger is the one to avoid.
What is the difference between barrel-pin and Type-C chargers?
Older laptops use a round barrel pin in a specific diameter. Newer thin laptops charge over USB-C Power Delivery. They are not interchangeable; check which port your laptop uses and the required PD wattage for Type-C.
My laptop says “plugged in, not charging” — is it the charger?
Often yes, especially if the laptop runs only while plugged in or charges intermittently. It can also be the battery or DC jack. See our diagnosis guide and test with a known-good charger of the correct rating.
