How to use

Power off the laptop, disconnect the battery if accessible, and remove the bottom cover following manufacturer service instructions. Locate the existing fan assembly and unplug its cable from the motherboard before removing any screws securing it. Install the replacement fan by aligning it with the original mounting points, secure it with the same fasteners, and reconnect the fan cable to the board. Reassemble the chassis, reconnect the battery, and power on the device to verify the fan spins and the system reports normal thermal behavior.

Usage recommendations

Perform installation on a static-free surface and use appropriate tools to avoid damaging connectors or screw threads. Clean surrounding heatsink fins and vents while the unit is open to maximize cooling efficiency. If the laptop continues to overheat after replacement, verify fan connector seating, BIOS fan settings, and check for additional faults such as degraded thermal paste or obstructed vents.
