T440 giving Fan Error

2015-08-24, 18:08 PM

I have a T440 that is giving a fan error message and then shuts off immediately. And, of course it just went out of warranty last month! :smileysad: Any ideas as how to fix?

It is a pain that it just went out of warranty. That seems early for a fan to die. I don't know how handy you are about doing things yourself. You just need a screwdriver, but some people are comfortable doing things like that and some are not. I am assuming the problem is the fan itself, because the only other part involved is the motherboard which is a much bigger issue. I would say that in 90% of cases it is the fan itself. The fan can be accessed by removing the bottom cover. The fan can then be removed and replaced. On newer machines, I always suggest a new fan, as opposed to a used one, which should come pre-pasted. Here is a link to the service manual. See what you think:

Thank you for the reply and advice. Yes, I am very handy and work on lots of computers as I am the IT director if a hospital. The manual is very handy and I had not been able to find it previously. I was actually leaning towards just replacing the fan.

Next important question... Can you help me locate the p/n for the fan and where can I buy it?

According to the parts list, if you have integrated (Intel)  graphics you need 04x3907.  With Optimus, you need 04x3908.

I tried to fix this urgently, and got lucky: I opened the back, quickly as there were only two screws, and checked for dust or maybe a stick placed there by my three-year-old. I saw nothing, so I blew on it and a little dust filled the air around my black brick (only bricked temporarily)

 

I then pushed the power button, and 'jump-started' the fan. Voila. POST completed and I enjoyed the laptop of old. When this repeated upon my next reboot, first the Fan Error, second the open-case jump-start, I realized others may benefit from this potentially-dangerous workaround. If it helps you, great. Good luck and god speed.

Re:T440 giving Fan Error

My daughter, in the midst of completing her time sensitive application for university, just had this error.  The laptop refused to start, just beeped and flashed Fan Error.  I followed these instructions for removing the outer case : https://www.ifixit.com/Guide/Lenovo+ThinkPad+T440p+Back+Cover+Replacement/122902

 

I could see immediately that a small screw had fallen onto the fan and was preventing it from spinning.  I removed the screw with tweezers and then used compressed air to blast off some of the accumulated dust.  The laptop booted right up without difficulty once I put the case back on and added the battery.  I have no idea where that little screw came from, I should probably figure it out as something is no longer secured, but at least she can now complete her application.  The case comes off really easily in case anyone else comes across this issue.
