Questions about this item

How do I install the 01LW091 fan in my ThinkPad A475 and what step is often missed?

Remove the bottom cover, disconnect the old fan cable from the motherboard header, swap the fan, then reconnect the cable firmly — the step most people miss is reseating the connector completely so the fan reports speed to the BIOS.

What maintenance or replacement will the EG50050S1-CAA30-S9A fan need later?

Blow dust from the heatsink fins and fan blades with compressed air whenever buildup is visible; if the bearing becomes noisy or the fan stops spinning at 5 V / 2.25 W, replace the whole 01LW091 assembly.
