Question Latitude E6430 Win 10 will not run on battery

[jblackmd]

I have been dealing with this issue for about a year. The computer runs fine on the adapter, which is a Dell product. Most of what I read pointed to a battery failure, despite the fact that the battery health reads good. But it is not a Dell battery, so I replaced it with a new Dell battery but the issue persists. If I start the computer and unplug it when it is logged onto Win 10, it will work for maybe a minute and then it locks up. It is noteworthy that the computer runs on battery if I am in the BIOS, or Safe Mode. It works just fine in those. I used the extensive Dell hardware diagnostic that shows no problems. I have tried removing the power supply and battery and pushing the start button to discharge it. I have uninstalled and reinstalled the Microsoft ACPI-Compliant Control Method Battery in device manager. I updated the BIOS. I have installed the Dell Power management app..

What gets me is that it runs on battery fine in Safe Mode, so I am thinking it must be some driver or process that is not turned on in safe Mode, but I am a loss as to which one it is. Any suggestions would be appreciated.

Look in Task Manager, Resource Monitor, and Process Explorer (Microsoft, free).

Compare what is running or not running in Safe Mode to what is running or not running when the system has been normally booted/started.

Take your time, be methodical, look/compare carefully.

Since it seems to be related to something you have installed, because it's fine in Safe Mode, I would try a Clean Boot of WIndows.

First uncheck any third-party services that you don't recognise or where you don't know what they do. Be prepared for things not to work however! Work your way through these third-party services, disabling each of them (or use a binary search technique) until you locate those which cause the lock-up on battery.
