Battery 1 (the clipboard/tablet battery) staying at 0% and not charging while Battery 2 (base/keyboard) works normally, after driver reinstalls and connector cleaning, indicates a hardware-level battery or charging fault in the tablet section rather than a software or configuration issue.
The documented troubleshooting steps for Surface batteries that map to what has already been tried are:
- Basic checks: different outlet, secure cable connections, correct power supply, and disconnecting high‑power accessories.
- Verifying the battery icon state (plugged in, not charging; battery not detected; etc.) and, when appropriate, removing and reinstalling the Microsoft Surface ACPI‑Compliant Control Method Battery / Surface Battery driver via Device Manager, then restarting.
- For devices that still will not charge or will not run on battery after these steps, the guidance is to proceed to service.
Because:
- Battery 2 charges correctly (so the charger and system power path are working), and
- Battery 1 remains at 0% and the device shuts off when external power is removed, and
- Battery drivers have already been removed/reinstalled and connectors cleaned,
the remaining supported resolution is hardware service for the Surface Book tablet section (battery and/or charging circuitry).
Next steps:
- If not already done, confirm the correct Surface Book power supply is being used and that the LED on the Surface Connect plug is solid when attached. If the LED is not lit or is intermittent, follow the charger troubleshooting in the charging article first.
- If the LED is solid and Battery 2 continues to charge but Battery 1 stays at 0% or shows as not detected, treat this as a battery hardware failure.
- Submit a service order for the device so the tablet section can be inspected and the battery or related hardware replaced if needed. Use the standard Surface service flow to check warranty and create a repair order.
If the Surface Book is owned by an organization, use the business/education service options; otherwise, use the consumer service path.
