"plugged in, not charging"

[Skyreaper]

Hi. I've bought my HP EliteBook 840 G1 in March 2014 and am experiencing this "plugged in, not charging" problem recently.

Everything is connected and i've tried uninstall the Microsoft ACPI Compliant Control Method Battery when i searched online for help but to no avail.

I've also done the battery test through the HP support assistant and they said that battery is ok and its functioning correctly. 

However the test also have said that my secondary battery was not detected. 

Can anyone help? 😞

Dear Customer,

Welcome and thank you for posting your query on HP Support Forum.

 Please shut down the laptop and disconnect the chrager and the take the battery out, also disconnect all the device and the cables if you have connected and then press and hold the power button for about a minute without the battery and the charger plugged in. After a minute release the power button and then just plug the charger and turn on the unit and then once the unit boots into windows insert the battery and check.

If the above step does not resolve the issue then please update the BIOS.

(Replying to the first solution post) This worked despite my skepticism; my laptop was dead as a doornail, and I thought I had tried everything...Thank you SJ Bradley, you may be a genius!
