Battery charge system is disturb much after remove gharge

As batteries age, they lose the ability to hold a charge. Think of your battery like an empty jar that you fill with water (charge the battery). Each time you charge it, you add a marble; that represents the degradation of the chemical reactions that take place each time it's charged and discharged. One marble doesn't make much difference, but over time eventually the jar is full of marbles. Now when you fill it with water, the amount it can hold is only a fraction of what it could originally take. So even though it's 100% charged, there really isn't much charge inside, and when it gets bad enough, you end up in the situation you find yourself where after being fully charged, it can't even power the laptop and shuts off immediately when the charger is removed.

First thing you'll want to do is check the battery health; that will tell you what the current capacity is versus what it should be able to hold. This page will show you how to check it both with a Windows command and with the HP Support Assistant.

How to Check Battery Health of Your Laptop

Once you know the battery health percentage, that will help judge whether it needs to be replaced (I'm guessing it does, based on your description). On an iPhone, Apple recommends replacing the battery when it gets below 85%, but the rule of thumb for laptops is anywhere in the 70-80% range. Generally you'll start seeing problems when the percentage gets down to 60-70% or lower, at which point it's time to replace it.

HP batteries are made to be easily user replaceable, and if you need instructions you can find them in the HP Maintenance and Service Guide.

The battery replacement procedure can be found on Page 48 (go to page 56 in your PDF reader). It's fairly short, so I copied it here for your convenience.

Before disassembling the computer, follow these steps:

1. 1. Shut down the computer. If you are unsure whether the computer is off or in Hibernation, turn the computer on, and then shut it down through the operating system.
2. 2. Disconnect all external devices connected to the computer.
3. 3. Disconnect the power from the computer by first unplugging the power cord from the AC outlet and then unplugging the AC adapter from the computer.

Remove the battery:

• 1. Turn the computer upside-down on a flat surface with the battery bay toward you.
• 2. Slide the battery release latches to release the battery.
• 3. Remove the battery from the computer.

Install the battery by inserting it into the battery bay until you hear a click.

Good luck, and be sure to come back and let us know what you find!
