HP Omen Laptop Not Detecting/Recognising Charger

[AJ-19]

Hi all,

I have had my Omen 15 (15-ek0003na) for about 2 weeks now without issue.

I'm not sure if this is connected with my issue but yesterday while I was using it I received a blue screen stating that an error had occurred and the system was going to restart. I don't remember much about the error as I was confused as to what was happening. Nevertheless the laptop restarted itself and supposedly was all fine.

While using the laptop I noticed the battery icon as if the charger wasn't plugged in, but it was. I've checked the AC adapter which is not loose, tried it in different sockets. There isn't any damage on the laptop or charger. 

I've had a look on the forums and tried uninstalling/reinstalling the battery drivers but this hasn't helped. The light next to the charging port doesn't light up either. The laptop just isn't recognising that the charger is connected! The weird thing is, when plugged in (regardless if it's connected to the laptop or not), the charger brick gets warm but absolutely no charge goes to the laptop. The battery is now on 23% and I'm trying not to use it as I know I won't be able to charge it.

Any help would be appreciated! Thanks

Hi@AJ-19, Welcome to the HP Support Community!

I understand that you have an  Omen 15-Ek0003na  and the battery not charging. You've done a remarkable job performing the steps. 

Did any software changes or updates happen on your laptop after which the battery stopped charging at 70%?

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

NOTE: You may skip any steps that have been performed by you already.

• 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.

Now let us uninstall the battery drivers and reinstall them. The following steps will help:

• Open the device manager. 
• Expand "Batteries". Right-click on the ACPI battery drivers and select uninstall. If there are multiple entries of the ACPI battery drivers then uninstall them all.
• Close the device manager. Restart the laptop.
• The Windows operating system will reinstall the battery drivers while restarting. 

It is a good idea to download and run a BIOS update for your laptop via this link. The charger must be connected until the BIOS update is complete to avoid any power interruptions due to the battery draining out. 

Post a successful BIOS update,  you may check if the battery charges fully. If not then please perform the steps as described in detail in this HP document. These steps help in testing and calibrating the battery. 

NOTE: Please skip the steps mentioned in "Test and calibrate the battery using HP Support Assistant".

Hope this helps! Keep me posted.
