AC adapter not recognised when laptop is on

[CrazyRatLady-14]

HP Laptop 15-bs506na
Serial Number : [edited]
Product Number : 3CD91EA#ABU

AC adapter is not recognised when the laptop is on. The blue/white light beside the input shows but it does not charge. When the laptop is off and connected to the AC it charges up and a red/orange light shows. BIOS is showing as corrupted and cannot be fixed due to the AC not being recognised when the laptop is on. This started suddenly, I use my laptop most days and the day before it was working fine. I have done a battery check and it passed. I have uninstalled both battery and AC drivers and checked for updates. I have done hard reset. When the battery is out the laptop doesn’t turn on with the AC alone. I don’t have another laptop so I’m just wondering what my options are.

Many thanks in advance for any advice!!!

Update,

BIOS is updated and no longer corrupted. The AC adapter still does't charge my laptop up unless turned off. It doesn't even show up as 'Plugged in, not charging'

@CrazyRatLady-14,

Welcome to the HP Forums 🙂 I would like to take a moment and thank you for using this forum, it is a great place to find answers. For you to have the best experience on the HP forum, you could also visit our HP Forums Guide for First Time Here? Learn How to Post and More. I see from your post you need assistance with the laptop AC adapter is not getting detected while the laptop is On. Don't worry we'll work together to help you find a solution.

To provide you with an accurate solution, I'll need a few more details:

Have you recently made any software or hardware changes on the PC before the issue started?

Are you using the original adapter which came with the PC?

Have you tried to uninstall the battery drivers and AC adapter from device manager?

In the meantime, let's try these steps here: 

Let's start off by performing a Hard Reset -

1) Shutdown the computer. 
2) Unplug all the Adapter and peripherals connected. 
3) Press and hold down the power button for 15 to 20 seconds. 
4) Plug-in the Adapter. 
5) Try to turn on the computer. 

Next thing, I would suggest here is to Run Windows Updates troubleshooter -

Download and install the troubleshooter from this link.

Now try to perform Windows Updates - 

1) In the search box, type and open Windows Updates. 
2) Check for updates. 
3) If the updates are available, click on install and restart the computer. 

If the issue persists, I would suggest  you go ahead and uninstall the Microsoft ACPI compliance battery and AC Adapter from Device Manager

Once done, shut down the PC.

Once again, follow the steps to do a hard reset on the notebook.

Insert battery alone, disconnecting AC adapter

Then reload BIOS to default: http://support.hp.com/in-en/document/c00034791

Save and exit. Continue to load Windows completely.

Shut down again. Plug in AC adapter.

Now restart again.

See if windows is detecting

If the issue persists, I would suggest here is to update the Bios and Chipset drivers on your PC from our HP support website, using this link.

Also, download and install HP support assistant on your PC. It should automatically download and install the latest updates and drivers for your PC.

Refer this link to know how to use HP support assistant.

Alternatively, I would suggest here is to follow the steps suggested in the support document for - HP Notebook PCs - Using and Testing the AC Power Adapter

Could you please respond to this post with the details and with the results of the troubleshooting as this will help me in further assisting you.
