Introduction

If your Asus Q252U (model BI7T9) BIOS passwords reset, its drivers are not working properly, or you hear a low beeping sound, use this guide to replace the CMOS battery.

The CMOS battery powers the BIOS firmware in your laptop. A faulty CMOS battery will stop transmitting power to the BIOS firmware.

Before you begin the repair on your Asus Q525U (model BI7T9) CMOS battery, make sure the laptop is off, disconnected from the charger, and to wear cut-resistant ESD gloves, to avoid damaging the internal components.

    • Begin by powering off the device and flipping the device over.

    • Carefully remove the two longer 9.5 mm screws on the corners with a Phillips #1 screwdriver.

    • Remove the eight 7.5 mm Phillips #1 screws on the back of the device.

    • Use an opening pick to separate the back cover from the device.

    • For easiest removal, begin by prying at one of the front corners and sliding the tool under the cover in a counter-clockwise motion (to the left) toward the laptop hinge.

    • Once the cover has been separated from the device, carefully lift the back cover off the device (begin by lifting from the front of the cover first).

    • The back cover should be easily removable, allowing full access to all of the internal components.

    • Use the point of a spudger to push on alternating sides of the CMOS connector to "walk" it out of its socket.

    • It may take a lot of alternating before the connector comes out. Be patient, and don't pull on the cables.

    • To reconnect the cable, align the connector and use a spudger or clean fingernail to push it fully into the socket.

    • Don't push on the cables themselves, or you may damage the connector.

    • Pull out the CMOS battery cable by the tab using tweezers.

    • Remove the CMOS battery.

Conclusion

To reassemble your device, follow these instructions in reverse order. Take your e-waste to an R2 or e-Stewards certified recycler.
