I think my old fan might work for long more, but read above. “How much time will it work without replacing the fan after I received the error for the first time? It works normally…but it makes noise and I receive the error…” (It did a strange noise.) I bought a new one, installed it by youtube “guides” and now its there spinning and working well. I got sometimes the “fan error” message at startup too, because the fan didnt spin.

The manual also says to take pink plastic piece off before installing, however the fan I was replacing still had it on and other people mentioned leaving it on so i did. It was not obvious what part was even going to come off as this section of the fan sits on top of a separate do-dad. I was concerned the hairdryer would damage other parts, but all seems to be fine. Once it started to loosen it was easy to come off before that it seemed impossible to get off. I used a hairdryer for at least 5+ minutes (very close to fan) until it got hot enough to gently pry off with a small flathead screwdriver. According to the manual, i have a LONG fan assembly. I finally found where some people had to use a hairdryer to heat up lower right corner of fan (square area) that seemed to be glued on (apparently this is Thermal paste). The photos and explanation were great, except I had a major problem getting my fan assembly out and could not figure it out until i searched several other forums. I just finished replacing the fan (under warranty) for my 1-month old refurbished T42p.

Different laptop types with different screen sizes use different fans, so you have to find the correct one witch fits your model. Just google the FRU number and find a place to buy it from. You can find a new fan assembly using the FRU number located on your failed fan, it might look like 91P8393, 26R7860, 13R2919, 13N5442, or 13R2657. You’ll find step-by-step laptop disassembly and fan replacement instructions in the HMM in the chapter “Removing and replacing a FRU” on the page 70.

It eventually became so bad that to boot up at all, I had to blow compressed air into the fan’s exhaust grill for 5-10 seconds, in order to fool the BIOS and make it believe the fan was actually spinning.Īccording to the IBM hardware maintenance guide (HMM) for ThinkPad T40, T40p, T41, T41p, T42, T42p this error message indicates a problem with the fan, you can find symptom-to-FRU index on the page58.
