Introduction

This guide will help you to replace your CMOS battery; sized similarly to a watch battery, this powers the laptop's real-time clock, and when it fails your computer may have difficulty 'remembering' its hardware settings, causing issues with day-to-day use.

    • Ensure your computer is completely OFF before starting this guide.

    • Remove the eight 6 mm screws using a Phillips #0 screwdriver.

    • Remove the two 11 mm screws using a Phillips #0 screwdriver.

    I have to know how long the pins are in the clips that hold the hinges in place. I don’t want to destroy my tablet.

    Mine had ten tiny little star screws. Not Phillips.

    • Pry the back cover off by inserting the plastic opening tool at the hinges and wedging it between the Back cover and the body.

    • Follow along the back edge with the plastic opening tool, lifting the cover off as you go. It is normal to hear snapping/clicking sounds as the back cover is held on by clips.

    • Remove the cover.

    • Using the JIS #0 screwdriver unscrew the three battery screws.

    • Remove the red and black annotated cable, pulling white head out of black port as indicated.

  6. JLy1hurgAmyllJ5Z

    • Ply the CMOS battery off with your finger.

    • The battery is attached to the computer by adhesive, but should come off by pulling with fingers; plying tool should not be necessary.

Conclusion

To reassemble your device, follow these instructions in reverse order.
