The other day, I had to reboot my X201 (normally it just goes to sleep). On boot up, it complained about the ubiquitous "fan error". Before reading about the "esc" escape, I was able to spin the fan manually to get past the error. Eventually, even that stopped, but fortunately I read about the "esc" trick. I was able to buy a replacement third party fan, but it never spun, and still got the fan error. Thinking it was a bad fan, I bought another third party fan from someone else, and got the same results. Any ideas on what to do next? Do I need to have a real Lenovo fan (FRU 60Y5422) because it has special sensor (like ink cartridages)? Or is there something wrong on the motherboard? Thanks in advance.

Most likely is that you have blown a fuse on the motherboard. There is a fuse (usually 0.5-amp) on the motherboard

I don't know or sure, but most models have it very near the fan connector. It needs some skill and a good temperature-controlled rework stations. Most repair places cannot do that sort of repair.

Assuming the fuse is the large gray cube in the picture, I was able to verify continuity with a multimeter. Then I checked for voltage between each pair of pins at the fan connector during power on, but got nothing.

I'm no expert, but that "large gray cube" should be an inductor, as the "L12" silk print on the board suggests. The fuse should be "F8", the white small surface mount chip with an "z" on top, located on the right side of the 6 pin black chip with "58A" on top.

I had the same issue: replaced the fan but the message (fan error) did not stop.
I checked the F8 fuse and it failed the continuity test onthe multimeter.
I decided to repair it myself: I improvised a lupe support and soldered (40W soldering iron) a small jumper on top of the F8, using a small rigid wire, ensuring both ends are shorted. Pictures below!
BTW, it worked! No fan error!

You should not be soldering a jumper wire across a blown fuse, the fuse is there for a reason, and blew for a reason, i.e. over current, the next time whatever fault that caused the fuse to blow will smoke your motherboard!!
