Windows 10: Bitlocker came up.... after I installed a new battery on my Dell laptop!

I replaced my battery in my Dell laptop, upon turning it on bitlocker came up.... I never installed bitlocker on this laptop. How did that happen? I don't want to erase all my files... Is this pulling from another computer that I have same email which I do have bitlocker on? or how do I unlock?

The battery of my laptop Dell Inspiron 5577 suddenly discharges from 71% to 7%

Hi

Welcome to Microsoft community.

From the symptoms you’ve described, it sounds like your Dell Inspiron 5577 is experiencing issues with battery calibration, power management, or potentially a hardware problem with the battery or related components. Here are some steps you can take to diagnose and address the issue:

1. Check Battery Health in BIOS/UEFI

• Restart your laptop and enter the BIOS/UEFI settings (usually by pressing F2 or Del during startup).
  
• Locate the battery health section. This can provide a more accurate assessment of your battery's condition.
  

2. Update BIOS and Drivers

• Outdated BIOS or drivers can cause power management issues. Visit the Dell Support website, enter your laptop's model, and download the latest BIOS and drivers (especially the battery and chipset drivers).
  
• Install the updates as instructed on the website.
  

3. Battery Calibration

• Fully charge your laptop to 100%.
  
• Disconnect the charger and let the battery drain completely to 0% until the laptop turns off.
  
• Recharge the battery to 100% without interruption.
  
• This process can help recalibrate the battery sensor to provide more accurate readings.
  

4. Check for Software Issues

• Sometimes, software or background processes can cause sudden battery drains. Run a clean boot to see if the issue persists and restart your laptop and observe the battery behavior.
  
• Disclaimer: A “clean boot” starts Windows with a minimal set of drivers and startup programs. It helps to determine whether a background service is interfering with your game or program and to isolate the cause of a problem.
  
  These steps of "clean boot" might look complicated at first glance. However, to avoid any trouble for you, please follow them in order and step-by step so that it will help you get back on track.
  

5. Replace the Battery

• Even though the diagnostics tools indicate that the battery health is good, it’s possible that the battery is defective, especially if it’s a third-party replacement.
  
• If the laptop is still under warranty or the battery is relatively new, consider contacting Dell support for a replacement.
  

6. Advanced Diagnostics

• Dell laptops come with built-in diagnostics tools that you can run to check the hardware. Restart the laptop and press F12 during the boot process to access the boot menu. Select "Diagnostics" and run a full test.
  

7. Driver Rollback

• If you suspect that a recent driver update caused the issue, you can roll back to a previous version:
  
  • Open Device Manager (press Windows + X and select Device Manager).
    
  • Expand the Batteries section, right-click on "Microsoft ACPI-Compliant Control Method Battery," and select Properties.
    
  • Go to the Driver tab and select Roll Back Driver if the option is available.
    

8. Contact Dell Support

• If none of the above steps resolve the issue, it might be best to contact Dell support for further assistance. They can provide more specific diagnostics and suggest potential hardware repairs or replacements.
  

Let me know if you need further assistance.

Best regards

Dell 7532 Battery will not charge. bought new battery same thing

• Go to Control Panel - Device Manager
• Expand the Batteries section
• Right click the Microsoft ACPI Compliant Control Method Battery and select Uninstall
• Close Device Manager and Reboot

If the above does not work, then it is probably the power lead (adapter). Dell systems are very particular, if it detects the wrong adapter it will not charge the battery. This can happen in error even when the correct power adapter is connected, please
try the solution below:

• Unplug the AC adapter from the wall outlet
• Disconnect any external peripherals connected to the Laptop
• Remove the battery. Refer to the User Manual of the Laptop for instructions on how to remove the battery.
  
  If the Dell laptop has a non-removable battery, skip this step
• Press and hold the Power button for 30 seconds to drain a residual power from the Laptop
• Connect the battery
• Plug the AC adapter to the Laptop
• Turn on the Laptop
