Re: Battery plugged in, charging - but really not charging

Thank you so much for the detailed answer. However, I asked Google in advance and have done BIOS factory reset. It's not help me. I have a special case. I will emphasize again. The battery indicator shows that the battery is plugged in and chargingSo for Windows everything is OK. But actually the battery is not charging! I assume that the fuse blows which is responsible for supplying voltage to the battery. May be someone can advise how to check it

Re: Battery plugged in, charging - but really not charging

I've checked everything, took out the battery and did everything from this topic. But the problem is not solved. HP Support Assistant shows that the battery is OK if not connected the power cable. If I perform the test battery when the power cable is connected, then I get the error PLJE24-000000-MFGJLJ-C0CG03. I checked the battery on another laptop and it works. Probably I have a problem with a controller battery in the laptop.

I Think That The Power Supply Is The Problem Here

Try To Plug In To A Different Outlet

You can try charging your Notebook using a know good Power Adapter and see how it goes

Re: Battery plugged in, charging - but really not charging

The power supply and the battery are absolutely OK because I've checked them on another laptop. The service center told me that they will change the motherboard(!). However, I think that would be enough to replace the fuse of battery charging. Thanks to everyone.

KNRK,

I noticed that under the batterylife section of your post you had "You need to let the battery drain completely before charging again", I have read in many places and may be misinformed but Lithium batteries do not have the memory issue that Nickel batteries have and thus do not require the full discharge, And that Fully discharging a Lithium battery can cause the battery to deteriorate and lose the capability to hold a charge.

Re: Battery plugged in, charging - but really not charging

I have followed all the instructions in the post edited by Oscar Fuentes on 04-21-2916, including installing the latest Biios and a new battery and the problem still exists.  I did notice that when I unplug the Power Adapter the icon shows the battery actually charging for about 30 seconds and then it stops charging although it still displays the heading "Plugged In, Charging".  Also, when running "Battery Check" without the Power Adapter plugged in the battery checks as OK.  When running "Battery Check" with the Power Adapter plugged in it shows the battery as defective.  Any suggestions on how to resolve this would be appreciated!
