Hi meyssamnaemzadeh1,
Thanks for reaching out Microsoft Community. We're sorry to know that the second battery of your Surface Book is no longer charging. This could be a software issue if in case you updated your Surface device and got this problem. To confirm whether
this is just due to any software related problems, or any corrupted drivers, did you install some updates recently? Have you tried detaching the keyboard?
If not, then you may detach the keyboard and let the charger sit to it to see if this will charge after couple of minutes. If this still won't charge, then we highly recommend to follow the troubleshooting steps below.
Method 1 : Re-attach the keyboard and run the Surface
Diagnostic Toolkit and check
Windows Update
Method 2: Uninstall/Re-install Drivers
Open
Device Manager
Expand Batteries
Right-click on the available drivers and select
Uninstall. If there is more than one driver, uninstall those as well.
Note: There should be 2 ACPI Compliant Battery Driver because your Surface and it's keyboard has separate batteries. If you get a pop-up, leave the box uncheck. Just continue uninstalling it.
Method 3: Update drivers and firmware
Check what is the current OS Build of your Windows version by going to
Settings > System > About.
Go to
Download driver and firmware for Surface, choose Surface Book then click Download on the next page.
Choose the .msi file that matches your current OS Build or the closest OS Build available and click
Next.
After downloading, run and install the .msi then
Restart the Surface.
