I thought I spelled out in the OP what this did to my Acer notebook laptop....it made it run significantly faster.
You did not “spell out” what FUNCTIONALLY CHANGED, merely the perceived result.
What functionally changed is memory no longer loads a driver, the driver called “Microsoft ACPI-Compliant Control Method Battery”. It is not your battery or a battery, but a driver running in the op sys that is among other things doing (supposed to be doing) power control management.
While you took it out memory, by disabling it, it is still on your system. There are instances of the op sys re-enabling it, though the triggers are apparently not consistent.
You can also uninstall the driver, so it is gone and not just disabled.
However - two things: It may in fact just be corrupted and NEEDING to be uninstalled and reinstalled. Yet, it seems if it is uninstalled and not reinstalled, a subsequent Windows update can reinstall it.
There - that’s what is actually going on.
Your system “running better” was a result, and from all you said you did it may be temporary. I’d uninstall the driver and install the latest update of it, then see how the system performs with it enabled. Then again, it’s possible YOUR system NEEDS an older version of the driver (compatible with your system’s chip set), which was replaced with an incompatible one during a windows update. You can also test that theory with the suggestion to uninstall, update and reinstall the driver.
You may have to do the disable routine on it after later Windows updates.
Good luck.
