Question about HP Pavilion dv9810US Notebook

1 Answer

I have an HP DV9810 laptop. The battery is not holding a charge. I have run the HP Battery checker and it is saying the battery is weak. I have since replaced the battery for a new battery and I am getting the same message. The battery is not charging up either. Is there anyway to manually check the connector pins from the motherboard to see if power is getting to the battery?

This issue could be due to hardware malfunction of the battery connectors pins on the notebook. However, to confirm the same, I would recommend you to perform the following troubleshooting steps which will isolate the exact cause of the issue.

Step 1: Hard Reset

To perform a hard reset, please follow the steps listed below:

1. Unplug the AC adapter from the notebook PC and remove from any port replicator or docking station.
2. Remove the battery from the notebook battery compartment.
3. Press and hold down the power button for about 20 seconds.
4. Insert the battery and plug the AC adapter back into the notebook PC.
5. Press the power button to turn the notebook PC back on.

Step 2: Reinstall Power Management Settings

Please follow the steps listed below to reinstall power management on the notebook:
1. Click Start/Pearl button and type ‘Device Manager’ in search field.
2. Double click on ‘Device Manager’ from the results listed.
3. Click the ‘+’ sign next to System Devices.
4. Right-click on the ACPI Fixed Features button and select Uninstall.
5. Now restart the system.
On restarting the notebook, Windows will automatically detect and install Power Management on the notebook.

Now connect the AC Adapter to the notebook and check if the battery is able to get charge. Incase, if the issue persists, then it is clear that the issue is due to hardware malfunction of the battery connectors.

As the issue is clearly related to internal hardware, the notebook requires a detailed onsite diagnosis by a service technician. Hence, I would recommend you to take the notebook to any nearest Authorized Computer Service Center to get it repaired/serviced.

I hope the information provided would be helpful to you.

Hp 8440p battery won't hold a charge


Since you have replaced the battery and the ac adapter then there's a problem with your computer's motherboard. Get it serviced by a technician if he says that you need to replace the motherboard then you better buy a new laptop. Motherboards are expensive.

If your battery will not charge, you need to run a test on some components on the laptop. The battery, the charger and the laptop itself. Once you detect the faulty conponent then you replace it
with a new one.

To test the battery:
1.Power off the laptop,
2.Take out the battery,
3.Insert it in another laptop,
4.Check of it will charge,

If the battery holds a charge there, then it means the problem is not from the battery, but if it does not hold a charge, then it means the battery is defective and need to be replaced with a new one.

To test the laptop:
1.Turn off the laptop,
2.Disconnect your present charger,
3.Remove your present battery pack,
4.Insert a well tested battery into the laptop,
5.Connect a well tested charger to the laptop.

All batteries have a limited number of load cycles, so if your battery/laptop is older or has been used intensively, this could happen.
You can try draining it completely, and then loading it completely, but it will probably not recover completely.
Make sure to save power when running on battery with laptops to maximize the battery life.

Message says battery not fully charged but Icon says 100% charged


This machine is roughly 4 years and so the battery does not hold the charge like it used to. It's just suggesting that you should look into a replacement battery that will hold the charge longer than the current one which will give you more time to use the device.

New battery wont charge.


It's sounding like a motherboard problem to me.
You've done all you can--the circuit on your motherboard that controls the charging is evidently gone bad on you.

Battery is showing its there and at 82% and charging but not charging and laptop crashes when mains fails ?


The laptop's battery might be weak to hold the laptop. The indicator will indicate the battery is ok, but when mains is removed there, it goes off. Try swtch on with only battery and see if it goes on and then off, it is the battery that is bad.
