- Alternatively, use a heat gun or hairdryer with even heat
Step 2: Lift and Remove the Screen
- Use a suction cup near the screen edges
- Insert plastic pry tools or triangle pickers

- Gently lift and remove the heat sink
Step 6: Isolate Power from the Logic Board
Power isolation is critical to prevent short circuits.
- Undo five screws holding the logic board
- Gently lift the board about 0.5 cm
- Insert a small plastic piece between the board and battery connector
- This safely disconnects power from the logic board

Step 9: Install the New SD Card Flex
- Place the new SD card flex into position
- Secure it using two screws
- Reconnect the SD card connector plug
- Reinstall the small connector shield
Step 10: Restore Power and Reassemble
- Remove the plastic spacer from the battery connector
- Secure the logic board using five screws
- Reinstall the copper heat sink
- Secure the heat sink with eight screws
- Place the internal shield back
Step 11: Reconnect Display
- Connect the LCD and touchscreen flex cables
- Secure both connector shields properly
Step 12: Reinstall the Screen
- Ensure the frame has enough adhesive
- Apply B7000 glue or tablet adhesive if needed
- Slide the screen into place from top to bottom
- Apply even pressure along the edges
Step 13: Clamp and Cure

FAQ’s
1. What causes SD card reader failure on Surface Pro 4?
SD card reader issues are usually caused by a damaged or worn SD memory card holder flex. Repeated card insertion, dust buildup, moisture exposure, or internal flex tears can prevent the tablet from detecting SD cards.
2. Is the SD card reader part of the motherboard?
No. The SD card reader on the Surface Pro 4 is connected via a separate SD memory card holder flex cable, which can be replaced without changing the motherboard.
3. Will replacing the SD card flex restore SD card detection?
Yes. If the issue is related to the flex cable or connector, replacing the SD card holder flex will restore normal SD card recognition and data access.
4. Do I need to remove the logic board for this repair?
Partial logic board lifting is required to safely disconnect power and access the SD card flex connector. This step prevents short circuits during the repair.
5. Is power isolation mandatory during this repair?
Yes. Although optional, isolating power by lifting the logic board and inserting a plastic spacer is strongly recommended to protect the board and connectors.
6. Can SD card issues be software-related?
In rare cases, yes. Always test with:
- A known working SD card
- Updated Windows drivers
If the issue persists, hardware replacement is required.
7. Is screen removal risky on Surface Pro 4?
Yes. The display is thin and strongly glued. Uneven heating or excessive force may crack the screen or damage flex cables. Always apply controlled heat and use plastic tools only.
8. Do I need new adhesive when reinstalling the screen?
Yes. Proper adhesive ensures screen alignment, dust protection, and long-term durability. Use B7000 glue or tablet-specific double-sided adhesive.
9. What should I test before sealing the screen?
Before final assembly:
- Test SD card detection
- Confirm display and touch response
- Ensure no loose connectors
- Check charging and power-on functionality
