Charging problems i have a hp pavillion dv6000 when connected to the ac adapter it says plugged in and charging, then the charge goes up to 100% then suddenly comes down to 87% and still says charging, it does that constantly. I did a battery check it says it is in good condition.This happened after a sudden power outage. do you know if it is the ac adapter problem and how do i fix it?

If the laptop battery is more than 3 - 4 years old then the battery could be worn out. Rechargeable batteries have a finite number of charge and discharge cycles and will lose their charge capacity over time, i.e. won't charge to 100% and gradually the charge reduces until the battery won't charge up at all. OR The battery shows a 100% charge but when the adapter is disconnected the battery drops off to zero capacity in a very short time. If the battery drops to an unacceptable charge level then the battery needs to be replaced.
Rechargeable batteries will fail if stored in a discharged state for long periods.

Inside? Yes. (If 'charger' is good)
Fuse?
No

Diagnostic flowchart:

A) AC adapter (Charger), has to be KNOWN to be good, before going on.
Used on a working laptop to see, or multimeter is used to check Voltage (DC)

The plug end that goes to the laptop, from the AC adapter, has a Center Hole, and a cylindrical outside metal shell.

The Function knob is set to DC Voltage. If just a symbol, the symbol is a dotted line over a solid line.
If more than one DC Voltage scale, the Function knob is set to the 0-50 Volt DC scale.

The Positive (Red) probe lead of the multimeter goes to the Center Hole, and the Negative (Black) probe lead of the multimeter, goes to the cylindrical outside metal shell.

You should be reading 19 Volts DC.

Also have an assistant gently wiggle the cable FROM AC adapter TO laptop, and the power cable TO AC adapter.
If there is a fluctuation on the reading, there is a broken wire, or wires, in one of those cables.

B) Check the DC Power Jack.
This is the jack on the laptop (DC_IN) that the AC adapter plugs into.

Has a Center Pin, and an inner cylindrical metal shell.
Battery removed, use an eraser on the end of a No.2 pencil, and see if you can GENTLY wiggle the Center Pin around.

ANY perceptible movement of the CENTER PIN, means replacing the DC Power Jack,
(By the way, is it an 8510p, or 8510w?)

Any movement of the rest of the DC Power Jack (Body), means replacing it; or may just mean the solder joints are cracked, and can be re-soldered.

C) AC adapter and DC Power Jack checks out?
Problem may be with Power MOSFET's on the motherboard, and associated MLCC's.

(Multi-Layer Ceramic Capacitor, and they are SMD/SMT just like the Power MOSFET's.

Pavilion DV6000 needs a 90watt adapter, with 4.8mm*1.7mm connector.

Hi, this information represents a basic troubleshooting guideline. Refer to your user guide for specific charging and connection instructions. Manuals may be available online in the Support Web site of HP.

Remove the battery from the computer.
Confirm the battery contacts are free of any foreign material that may prevent charging.
Reinsert the battery into the computer.
Verify that the AC adapter cord is properly connected and plugged directly into a known working AC power outlet.

NOTE: If the battery charges correctly when the AC adapter is plugged directly into an AC power outlet, but not when plugged into a power strip or surge protector, the problem is with the power strip or surge protector and not the computer battery or AC adapter.

Verify the correct AC adapter is being used.
Ensure the AC adapter box power light is on. This will be an illuminated green light.
If the AC adapter power light is not on, the AC adapter and power cord will need to be replaced.
Verify the charging indicator is illuminated on the computer.
If the issue still exists, install a different compatible HP battery, if available.

NOTE: If a replacement battery charges and operates correctly, the problem is with the first battery.

If neither the original nor a replacement battery charges, service may be required for the computer.

Go to Control Panel > Power Options
You will need to change the setting for when it is connected on battery and when it is connected on power.

If the AC adapter is not recognized by the system, the battery charger circuit is disabled. Things you can check:

1. In the barrel of the connection to the computer, the small wire in the center is the sensing wire. If bent or broken, then the adapter will need to be replaced.
2. If the pin is not bent or broken, try a different AC adapter (Any D-Series Dell adapter will work) IF that adapter works, replace the AC adapter.
3. If a known good/new adapter doesn't resolve, then a motherboard needs replacement.

Hi, when using the (AC Power Adapter), it is important that once the (Battery) is fully charge; to do one or the other. Stop! using the AC power, shutdown the computer, and unplug the AC power; use the battery (only), or remove the battery, and use (only) the AC power. Note: Using both power sources this can cause damage to the battery, by over charging, and possibly over heating the computer. Thanks paul7of9

1. First remove the Battery, clean the Battery contacts with the pencil eraser and insert the Battery in the Computer.

2. Connect the AC Adapter (Battery charger) securely to the Computer and the Power outlet.

3. If the issue persists, try connecting the AC Adapter to different Power outlet.

4. Make sure that both the connecting points (DC IN port on the Computer and the Power outlet plug) are securely connected and not loose.

5. If the issue persists, try with different AC Adapter.


Good Luck!!!!!!!!!!!!!

Your battery is dead when it no longer will hold a charge. Replace your battery.

As others have said, the most common fault with the ZV series is the power socket. However, you mentioned the Lightning Bolt. This indicates that the battery is being charged and it should go out as soon as the battery is fully charged.

If the Lightning Bolt flashes on and off regularly, especially when the power cable is moved, then the socket is at fault and needs replacing.

You can check to see if the battery is receiving a charge by doing the following

1. Right Click the Desktop
2. Click Properties
3. Click the Screen Saver tab
4. Click the Power button
5. Click the Power Meter tab

This will tell you the computer's current power source and whether the battery is charging.

I have replaced several of these sockets on ZV5000s and I'm sure the 6000 will be similar. I would not recommend this job for anyone without technical knowledge, despite some of the websites that say you can do it yourself. You will need to strip the entire laptop down and all but remove the motherboard before the socket can be replaced.

Hope this helps
