⚠️ Important: This adapter uses the 7.4mm × 5.0mm barrel plug with a center pin (HP "Big Pin" / Large Tip connector). Please verify your laptop's charging port matches this connector type before purchasing. This adapter is not compatible with HP laptops using the smaller 4.8mm × 1.7mm "bullet" connector, Slim Tip, or USB-C connectors.

FAQ

How do I verify if this adapter is compatible with my HP laptop?
Check two things: First, look at your laptop's charging port—it should be a round barrel plug approximately 7.4mm in outer diameter with a visible center pin. Second, check your current adapter's output specifications—if it says 19V and the wattage is 90W or less, this adapter will work. If your laptop requires more than 90W, this adapter may not provide sufficient power.

Can I use this 90W adapter on a laptop that originally came with a 65W adapter?
Yes. A higher-wattage adapter can safely power a lower-wattage laptop—the laptop will only draw the current it needs. The 90W adapter provides extra headroom and will run cooler than a 65W adapter under the same load. However, do not use a lower-wattage adapter on a laptop that requires 90W, as it may cause charging issues or system instability.

What is the difference between the 7.4mm connector and the 4.8mm "bullet" connector?
HP used two different barrel connectors during this period. The 7.4mm × 5.0mm (this adapter) is the larger "Big Pin" connector with a center pin, used on Pavilion dv series and many ProBook/EliteBook models. The 4.8mm × 1.7mm is the smaller "bullet" connector used on thinner models. They are not interchangeable—please verify your connector type before purchasing.

My laptop is not charging. What should I check?
First, verify the wall outlet works. Second, check that the connector is fully inserted—the 7.4mm plug should click firmly into place. Third, inspect the cable for visible damage or fraying. If the adapter feels warm but the laptop isn't charging, the issue may be with your laptop's charging port or battery. If the adapter remains cold, it may have failed internally.

What are common signs that my power adapter needs replacement?
If your HP laptop intermittently stops charging, the adapter makes buzzing noises, runs excessively hot, has a frayed or damaged cable, or fails to power the laptop at all, it's time for a replacement. This PPP012H-S is a direct OEM-specified replacement for these scenarios.
