The valve is working, but it is already loud, the control probably has a problem with selecting the speed. I disassembled it, but its design prevents any oil dripping or any other means of maintenance.
I had the same problem, just unscrew all the screws (7 pcs) and you can download the heat-pipe. The fan itself stays only on the magnet, you just need to pull it off, blow the whole thing off, and to the inside of the sleeve in which the fan rotates, give a drip of grease mixed with machine oil.
Hello, I got a Lenovo R61i, which after turning on it restarted after a few seconds without giving any image on the matrix. The BIOS battery has been disconnected for a few days and the laptop shuts up with just a FAN Error in the top left corner. Apparently the house in which it was used was hit by lightning or lightning struck somewhere next to the house. The fan connected to 5v turns like crazy, so it is operational. I also connected another windmill and there is also silence. On the other side of the disc I found quite suspicious browning, but I don't know if that could be the reason.
Hello, I reheat the topic: I have a question in my r61 and there is an error fan error when the esc key is pressed, the system boots normally and you can work normally, if the esc key is not pressed, the notebook turns off. The fan's fault is gone because it has been replaced with a new one. After connecting another fan, e.g. from another notebook (three-wire cable), the fan accelerates and slows down in pulses, the bios changed to the latest available. I have no idea what's wrong with him .... Maybe someone met with such behavior? Most of the fan errors are described as a damaged or dirty fan ... in my case it doesn't work because I installed a completely new cooling system with the fan, the error also occurred on the old system ...
Hello, I am struggling with the same problem. I also replaced the windmill with a new one and the same problem. I noticed that when it is cold, it starts up without a problem, i.e. the fan passes the initial test after turning on, then turns off and turns on when the heat sink gets a sufficiently high temperature. Everything is fine, I can turn it on and off any number of times and there is no FAN ERROR message. On the other hand, when the heat sink heats up to a very high temperature, the speed of the fan starts to go crazy sometimes faster and slower. When I turn it off and on again, it doesn't even pass the startup test. It only vibrates and cannot take off. Then the message FAN ERROR appears. Has anyone else encountered such a problem? Maybe some schematic? I do not even know what system to look for on the motherboard responsible for controlling the fan.
Hello, and has anyone found a way out of such a stalemate as a fan error in the Lenovo R61? Despite replacing the cooling system with a new one, the problem still exists ... The brand Lenovo (IBM) has lost in my eyes ...
Thanks to the fact that I have this manual on my computer for a long time, I am actually starting it, well, but the paste has been changed, the fan has also been changed as for the motherboard. it takes a schematic to find the element responsible for fan control, and this is where the problem arises ...
Check the transistor through which the fan is controlled - maybe it has lost parameters and gives too low supply voltage, which is reflected in the lack of detection of the fan / speed by the control system.
Hello. Finally, after many weeks with the message "FAN ERROR", the laptop (LENOVO T61 / TYPE 7649-CTO) could not be started at all. As I did not have the paste on hand, it was not an option to tear off the entire cooling system with prock and chipset. Encouraged by my colleagues' information about the positive effect, after lubricating the fan, I decided to do it with a spray lubricant. After possibly thorough vacuuming and blowing the fan and its surroundings, I slightly pry the plastic fan casing (where its electronics are) and sprayed the lock defroster, one that "lubricates and protects" (there was nothing else in the house). And it goes ... In addition, very quiet. Of course, sooner or later he will probably rebel, but for now his wife will be happy
@Damianko I have r61 with intel integrated. How did you manage to oil it without dismantling the heat sink? Or maybe the wr / t61 windmills are different and it is enough after removing this metal cover:
Edit2: 2 drops inside and one on the spindle and around the magnet - maybe I exaggerated a bit, but I really didn't want to disassemble it for the second time. The first start-up made me scared that the windmill did not work, it took off so quietly,
I assumed 2-3 hours and as usual it was 4-5 because of poor screwdrivers and occasional hard screws to unscrew. So it's worth getting a decent and hardened set of screwdrivers.
Hey, nice to have a topic like this. I have the same problem, but for now I'm turning on the computer for about ten minutes - temporarily - and maybe I'll rush to the service to lubricate it. This is the only way to bypass the message: Fan error. The windmill may be a little too loud. For me, it is also a factory drawback - judging by what you write - because even on the website they told me that the systems related to the cooling system on the motherboard are broken and I do not know how you mostly solved your problem, but I am not convinced if it is enough replace or smear something. It is also a suspicious matter. How was it with maintenance?
I haven't had fan errora yet, but the windmill was growling unbearably. I undressed, greased and it runs flawlessly. From what I read earlier on foreign forums, there were cases that lubrication or replacement of the cooling system helped. There are also "fix fan error" videos on youtube. So if replacing it helps, there is a chance that lubricating it will also help.
Now I'm playing with the fan to fold the correct config. ElementaryOS Luna screen and tpfand in action (youtube 480p fired in the background). If I do not move anything, the fan turns off. It works rather softwear:
I did not start the fan, but I dripped a few drops of machine oil on it (probably machine oil) and it would turn on, but I think it's also a matter of temperature, because in the summer the fan error could not be underestimated. However, from what I noticed, you probably need to buy the original fan (about PLN 70), and on YouTube they show the definitive removal of the problem. What could the motherboard layout have to do with it, seeing that it is more a question of bearing mechanics? The original fan (Allegro), and the system will work ... Otherwise, ignoring the problem will cause it to not turn on at all. It would be suitable for maintenance, because I had no experience with laptops - I did not know that the economic problems with cooling such machines would come out so quickly. It was supposed to be crude, although I don't even know if it is impossible to neglect the stationary one.
In these, the IBM BIOS tests the fan speed and reports an error when it deviates from the defined values. The most common reason for this error is a worn fan bearing - just check if the impeller vibrates sideways - you will feel loose fingers, if they are, it doesn't make sense to lubricate it because it is fun and the problem will keep coming back. Replace it with a good substitute with identical parameters or the original. There are only new coolers available on the market, without heat sinks.
