Your HP Pavilion will not power on, and the barrel plug on the charging brick looks physically cracked or wobbly. This page shows you how to confirm the damage and get the correct replacement without guessing.
In short: Yes, a cracked laptop charger plug can be fixed, usually by replacing the entire power adapter. Do not attempt to repair the internal wires yourself. A blinking light with no power indicates a broken circuit or poor contact, so you need to test the connection and then buy a new, certified charger.

Why the Light is Blinking and the Laptop Won't Start
A blinking power light on an HP Pavilion usually signals a charging failure. The laptop is detecting power, but the connection is unstable. This happens when the physical plug is damaged. The other half of this decision is repair lenovo usb-c.
If the barrel plug is cracked, the metal pins inside might be bent. When you plug it in, the pins do not make solid contact. The circuit opens and closes rapidly, causing the blink.
- Cracked outer shell on the DC plug
- Bent or loose pins inside the connector
- Broken internal wire near the plug head
- Dirty or oxidized charging port on the laptop
Safety first: Do not use a charger with exposed wires or a cracked housing. This is a fire and shock hazard. Stop using it immediately.
Step 1: Inspect the Crack and Check the Pins
Hold the charger plug up to a bright light. Look for a visible crack in the plastic barrel. If the crack goes through the whole plug, the part is broken.
Look inside the barrel with a flashlight. The small pins should be straight. If they are bent or missing, the charger is dead. You cannot usually fix a bent pin safely at home.
Check the cable where it meets the plug. If the wires are frayed or the strain relief is snapped, the internal circuit is broken. This is common with cracked plugs.
Also inspect the main power brick. If it is warm or smells like burning plastic, stop using it immediately. These are signs of internal failure that no external repair can safely fix. It helps to understand battery charging failure before going further.
Pro tip: Power off and unplug everything before you open any part of the charger or laptop.
Step 2: Test the Charging Port on the Pavilion
Sometimes the charger is fine, but the laptop port is the problem. If you have a working charger for another laptop with the same plug type, test it.
If a known-good charger works, your original charger is broken. If neither charger works, the port on your Pavilion is likely loose or dirty.
Use a can of compressed air to gently clean the laptop port. Blow out any dust or debris. Check the port for cracks in the plastic.
Watch the blinking light while you move the cable gently. If the light stops blinking when the cable is held in a specific position, the internal wire is broken at that point. If the light stays blinking regardless of position, the connector itself is faulty.
Safely removes debris from the port without damaging the pins.
- Removes dust, dirt, and debris from keyboards, computers, laptops, printers, gaming
- USE NOZZLE – Provides controlled airflow to reach tight spaces, vents, ports, and
Step 3: Match the Correct Replacement Adapter
You need a charger with the same voltage and higher or equal amperage. Check the label on your old charger. Most HP Pavilion laptops use 19.5V to 20V output. If that sounds like your bench, read up on repaired hdmi connector next.
Identify your connector type. Older models use a round barrel plug (often 4.5mm or 5.5mm). Newer models use USB-C. Do not mix these up.
If you have a USB-C Pavilion, you need a USB-C charger that supports the laptop’s wattage. A 45W or 65W charger is usually sufficient.
For barrel plugs, measure the inner and outer diameter of the hole. HP often uses a specific size. A universal charger with the wrong tip will not fit securely and can crack the new port.
| Connector | Typical Use | What to Buy |
|---|---|---|
| Round Barrel | Older Pavilion | HP-specific barrel adapter |
| USB-C | Newer Pavilion | USB-C 45W/65W adapter |
This 65W USB-C charger fits the HP Pavilion 16t series and provides the correct power.
- Input: AC 100-240V 50-60HZ; Output: 20V 3.25A 65W (Also compatible with 20V 2.25A 45W)
- Connector Size: External diameter: USB-C (Note: Please make sure the DC output and tip
Step 4: When to Replace the Charger vs. Repair the Port
Replacing the charger is the safest and cheapest fix for a cracked plug. Internal charger repairs are not recommended because of safety risks.
If the laptop port is broken, you need a professional repair. Do not try to solder the port yourself unless you have advanced skills.
A cracked plug means the charger is end-of-life. Get a new one. If the port is loose, back up your data immediately before any repair. We cover DIY charger port repair in a guide of its own.
Avoid generic chargers with significantly lower wattage. If your laptop needs 65W, a 45W charger will charge very slowly and may cause performance throttling under load.
Pro tip: Always back up your files before taking the laptop to a repair shop for port work.
How to Stop It Happening Again
Cracked plugs usually result from pulling the cable instead of the plug when unplugging. Always grip the connector head, not the wire.
Store the charger loosely. Do not wrap the cable tightly around the plug, which stresses the internal wires.
Keep the charging port clean. Dust buildup can push the plug in unevenly, cracking it over time.
Use a surge protector for your outlet. Power spikes can damage the internal components of the charger brick, leading to failure even if the plug looks fine.
- Unplug by the connector, never the cable
- Coil the cable loosely for storage
- Check for fraying wires monthly
- Keep the port free of dust and debris
The bottom line
A cracked HP Pavilion charger plug usually means the adapter is broken and needs replacement. Do not attempt to fix the internal wires. Buy a matching certified charger based on your connector type and wattage.

Frequently asked questions
Can I glue a cracked laptop charger plug?
No. Glue does not fix the internal broken wires or bent pins. The plug will remain unsafe and likely will not power the laptop correctly. Replace the charger instead.
What does a blinking light on an HP charger mean?
It usually means the power connection is unstable. If the plug is cracked, the pins are not making solid contact. The laptop sees power, loses it, and blinks the light.
How do I know which charger fits my HP Pavilion?
Check the label on your old charger for the voltage (usually 19.5V-20V) and the plug type. For USB-C models, check the laptop’s power requirements for the correct wattage.
Is it safe to use a charger with a cracked plug?
No. A cracked plug can expose live wires, causing shocks or fires. Stop using it immediately and replace it with a new, undamaged adapter.
