Sir  ,

          i am using hp 15 notebook pc since last 3 year . from the last  1 month i am facing a problem regarding battery shutdown , as when battery % reached to 20% laptop shutdown automatically ,without any warning notice as earlier i got this at 10 %  earlier . i posted  a feedback regarding this  yesterday still i did not get any response from you . 

                     Today i came to know about  hp battery programme validation from hpsupportforum , so i got through the hp battery programme validation utilty  . after validating it showed battery is not affected by recall programme & replacement is not necessary .

  so , plz solve my issue .

Welcome to HP Support Forums. 🙂 I came across your post and would like to help.

I understand that you have an HP 15 series notebook. I read that the when the battery charge comes down to 20%, the laptop powers off. Not worry, I'll do my best to help you. 

To understand more about how your battery works: Click here 

I recommend you to perform the following steps to isolate the issue and arrive at a fix: 

• Power off the laptop.
• Remove the battery out. If the battery is integrated and does not have a latch to release it then leave the battery inside the laptop.
• Disconnected AC adapter from the laptop.
• Press and hold the power button for 15 seconds.
• Reconnect the battery and plug the AC adapter.
• Power ON the laptop.

Please perform the steps as described in detail from this HP document. These steps help in fixing battery related issues. 

NOTE: For Step: Test the AC adapter using the UEFI Hardware Diagnostic tests, I suggest try running a test on the battery instead. Incase the battery test fails then you may contact our HP phone support team to check the available service options. 

I sincerely hope this information helps. Feel free to keep me posted. Good luck! 🙂

Thank u sir , for ur kind solution .

         I followed ur suggestion , as removing battery then disconnecting plug ac adapter , then again recoonecting battery , plug in adapter . one thing i will say , i didnot understand meaning of this  line " If the battery is integrated and does not have a latch to release it then leave the battery inside the laptop. " 

    after go through the above step , nothing  will be changed  , samething was happend , laptop shutdown without warning .

       besides this i also followed testing and calliberating of battery which is mentioned in hp document . i applied 2 steps i.e 1. through hp support assistant  2 . hp pc hardware dignostics UEFI .  in fist process i got the +ve result ( find the attachment ), but  in second step there was no opion for component test & power test . only 2 steps were available hard drive test and memory test .i here by attached the some snap shot of thishp support assistant testhp battery power test

You're welcome and thanks for sharing the images.

You may update the HP UEFI hardware diagnostics menu and then you should get an option to perform a battery test. Please download and install it on your laptop via this link.

Once installed, please restart the laptop. Then you may try the steps 2 to run the battery test (usually found in power test). If the battery tests good then please perform the steps from this HP article to improve the battery's performance.

A battery's life depends on the number of power cycles it goes through. One full charge and then full discharge is a power cycle. 

If you would like to buy a battery, then it is better to contact our HP phone support team or visit the HP PartSurfer website.

Hope this information helps. Good luck! 🙂

It looks like you were interacting with @MKazi, but he is out for the day & I'll be glad to help you out, 

I'm the Riddle_Decipher & I'm at your service. 

I reviewed your concern and the entire conversation, did some research and here's what I recommend:

It looks like the battery connection is either loose or malfunctioning considering the tests you've done,

And the best thing to do, is to Contact HP to have the battery replaced:

HP Support can be reached by clicking on the following link:  

* Open link:  www.hp.com/contacthp/

* Enter Product number or select to auto detect

* Scroll down to "Still need help? Complete the form to select your contact options"

* Scroll down and click on HP contact options - click on Get a Case & phone number.

They will be happy to assist you immediately. 

If the unit is under warranty repair services under the manufacturer's warranty will be free of charge.

If you would like to thank me for my efforts to help you, 

feel free to give me a virtual high-five by clicking the 'Thumbs Up' icon below, 

Followed by clicking on "Accept as solution" button for my efforts to help you.

Have a great day!

This is still a problem in the implementation of UEFI by HP, it should provide the current level of battery wear through the ACPI interface. But instead it says that the battery is in perfect condition, which is not true. UEFI simply gives the operating system the wrong information about the current state of the battery, which makes the laptop turn off instantly when the energy is really running out.
 I encountered the same problem and, apparently, it can only be solved by HP or, perhaps, someone who can modify UEFI-image.

hlo jbox ,    

                    i have the problem in primary battery as it doent hold charge below 20 % and shutdown wthout any warning . as per HP EXPERT  sol . i have to replace that battery , as it goes weak that i know throw hp uefi dignostics .

                                      I  think you have to check your HP UEFI hardware dignostics  update for test of power souce  , then see what happen .

                 So , please wait for hp expert or hp employee's solution regarding your matter . let them to touch u soon .
