ThinkPad W510 fan error

2021-01-13, 21:40 PM

I got fan error at booting. No fan rotation at all. How can I check if it is motherboard or fan fault? Where I can find fan fuse?

Welcome to the forum.

 

It's most likely the fan. The W510 is now a decade old. The fan bearings either wear out or get clogged by dust. Try a drop of light oil on the fan to see if that frees up the fan. If the fan turns at all with power then it's not a fuse. At that point you may want to explore getting a new thermal module with fan, assuming you can still find them.

 

See the ThinkPad T510, T510i, and W510 Hardware Maintenance Manual 1150 Thermal module for more info.

Hi!

 

Thank you! There is no dust on the fan. And manual rotation is very smooth and easy. That‘s because I would to check motherboard and fuse before ordering new fan.

Perhaps disconnect the thermal module plug, then

  1. Check for voltage at the pins on the motherboard. If there is no power to the fan at those pins then that would indicate a blown fuse on the motherboard.
  2. Apply voltage from an external source directly to the fan. If it doesn't spin then there is friction in the bearings.

I'm not sure what voltage the fan needs. That information may be on a label on the fan or could be found by Googling on the FRU number.

I checked both variants:

1. Fan is no spinning at 5V supply.

2. There is no voltage on motherboard pins.

 

Where is the fuse located?

Probably near the connector, but I don't have direct experience with W510.

I don't have a W510 but I have worked on them.  Other models of that age had 2-amp fused labeled F4 near the connector on the same surface of the board.
