Secondary Replacement Battery does not work

HP EliteBook 8570w
Microsoft Windows 10 (64-bit)

The below suggested resolution was provided back in 2012 and I wanted to know if it is applicable for a secondary battery replacement? I have a purchased a replacement for Battery # 2 (auxiliary) and it is not charging.

See previous suggestion below, but if you have any other ideas that would be helpful before I return it; that would be great. Thanks.

Hello amj205. I understand that your battery is not being detected. Is this correct?

I do believe uninstalling the ACPI driver is a good place to begin. I combined this reinstallation with a hard reset so make sure to perform these steps exactly.

  1. Open Device Manager (with both AC power and battery connected).
  2. Expand the battery section.
  3. Uninstall all compenants listed here.
  4. Shut down the notebook.
  5. Remove battery and AC power.
  6. Press and hold power button for one full minute.
  7. Replace battery ONLY.
  8. Boot the notebook and allow Windows to reinstall the drivers.
  9. Verify that this resolves the issue and post the result.

Let me know the result. I hope you have a great rest of the day!

Secondary Replacement Battery does not work

I just got an OEM BB09  634087-001 CT: 6BRSR21B25D028 for my 8570W. I read voltage at the - & + posts and got 1.07 volts. Can HP send me a new one?
