Will the laptop operate without a power source?
Laptop Model: Dell Latitude E6430
OS: Windows 10
I’ve been experiencing this problem for nearly a year. The machine functions properly with the adapter, which is a Dell product. Most sources suggested a battery failure, even though the battery health appears normal. However, since it’s not a Dell battery, I swapped it out with a new one, but the issue continues. When I power on the computer and disconnect it while it’s logged into Windows 10, it operates for about a minute before locking up. It’s interesting that the system runs on battery when I’m in BIOS or Safe Mode. It functions perfectly in those settings.
I ran the comprehensive Dell hardware diagnostic and found no issues. I removed the power supply and battery, then tried to discharge it by pressing the start button. I also reinstalled the Microsoft ACPI-Compliant Control Method Battery via Device Manager and updated the BIOS. Additionally, I installed the Dell Power Management app.
What bothers me is that the laptop runs smoothly in Safe Mode, so I’m guessing there’s a driver or process active there that isn’t enabled. I’m struggling to identify which one it is. Any advice would be greatly appreciated.
Check Task Manager, Resource Monitor, and Process Explorer (Microsoft, free). Contrast the activity in Safe Mode with the state after a normal boot.
As it appears connected to an installed application, since it functions in Safe Mode, I would attempt a Clean Boot of Windows.
Remove any unknown third-party services first, and be ready for potential issues. Proceed step by step through these services, turning them off one by one (or using a binary search method) until you identify the ones responsible for the battery lock-up.
Remove Battery and its controller along with the Microsoft adapter from Device Manager
Restart
Battery
It operates without issues in Safe Mode, which suggests it might not be essential. However, running smoothly in Clean Boot that blocks all non-Microsoft services raises a concern. Were all auto-start applications disabled through Task Manager Startup Apps? If not, please adjust them, as an unresponsive app could be the cause.
If the problem persists, it may point to a deeper Windows issue. In Safe Mode, only a reduced version of Windows is loaded, whereas Clean Boot displays the complete system. Run the following commands in an elevated command prompt:
Code:
dism /online /cleanup-image /restorehealth
sfc /scannow
Is the battery actually charging? Does it display the percentage charge? Consider removing the battery and its controllers during safe mode.
