Sphinx Fix

[Vexinator]

Hello,

Does anyone still have the Sphinx fix available to share? I have a late-2016 spectre x360 (model  13-w0XX) and have the battery drain issues. I had been using a separate company laptop for the past few years as my primary didn't really notice this slow discharge until recently. 

Thank you in advance!

Thank you for joining HP Forums.

It's a pleasure assisting you in finding answers to your technical queries.

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

Did you make any software or hardware changes to your PC?

Let's try updating BIOS on your PC and check if it helps. Also.try updating the drivers on your PC using HP support assistant and check if it helps.

Refer to this article to know more information about usingthe HP support assistant.

Also, try the steps recommended below.

Step 01. Click on the Start Button
Step 02. Type "Device Manager" in the start search box & open the Device Manager
Step 03. Look for Batteries and expand it by click on the + symbol on the left
Step 04. Right Click on "Microsoft ACPI Compliant Control Method Battery" & uninstall
Note: This Battery driver will get reinstalled automatically when you restart the Notebook again
Step 05. Please Shutdown the Notebook
Step 06. Please remove the Battery and unplug the Power Adapter
Step 07. Press and Hold the Power Button for full 1 Minute
Step 08. Go ahead and put back the Battery and connect the Power Adapter
Step 09. Look for "Plugged In Charging" message on the Battery icon
 
After performing all the steps if you are facing the same issue still, please perform three more steps:
1. Run a Battery Check in HP Support Assistant[Install the Software if it's not available]
Note: Replace the Battery If Health Check Status shows Replace
2. Update the latest BIOS for your Notebook from HP Support Site
3. Please check your Notebook with a known good Power Adapter & Battery from a different Notebook 
Note: If a known good battery is also not charging we need to replace the system board.

Also, refer to this document to understand more about calibrating batteries.

Keep me posted, how it goes!

Hello @raj1788,

Thank you for your response. I have tried the recommended steps below including ensuring the BIOS is up to date and uninstalling the "Microsoft ACPI Compliant Control Method Battery." I have not had any improvement in the battery drain on standby after these changes and updates. The battery check indicates the battery is healthy. My notebook model is HP Spectre x360 - 13-w023dx.

This seems to have been a common issue and my review of prior posts indicates the best known solution is the Sphinx fix which does not appear to be available publicly.

Thank you!

Appreciate all your time and efforts.

I'm afraid, you have to contact HP phone support for further assistant.

Can you please check your inbox on the forums page for the private message.
