Chromebook tends to randomly shut off.

Before the device shuts off, does it seem hot to the touch while the fan emits no sound? The cooling fan might not be turning on due to a blown motor or a disconnected fan header.

This can cause the device to shut off randomly due to overheating. If it appears that the fan header is connected properly, use this repair manual to remove and replace the cooling fan.

Does your fan seem to be running full speed most of the time or make strange noises? The heatsink fan may be clogged with dust, or the blades may be physically obstructed causing drag on the fan.

Clear the dust from the fan with compressed air, and visually inspect for any physical obstruction in the heatsink. If the problem persists, remove the heatsink and reapply the thermal compound by following our repair guide.
