Laptop Lenovo R61 - Fan Error.

Hello.
I have a problem with the fan in the lenovo g770 lap, namely I have cleaned the cooling system prophylactically, etc. I put everything as it should be and the fan started to tickle me, I wanted to lubricate it, but unfortunately I have a problem with taking it apart, please help, I put pictures of the fan.
Regards.

You probably damaged it, replacing the fan in your case.

Probably not because normally it works, it just spins like that. And anyway, as if I could damage it as soon as I cleaned its dust from its blades.

By doing so, you have unskillfully destroyed the fan. It's only eligible for replacement now, I've been through this before.

I have already cleaned such fans is my first time and the best thing happened to me in my case , nom but nothing I have struggled with him for a long time today and I made him for as long as it remains to be seen I will be looking for a spare just in case.
So thanks so much for the information everyone.
Regards.

Hello, I have to warm up the topic.
The old fan started to die, so I decided to buy a new one. I replaced it and it turns out that the laptop does not start, I connect the old one is ok. I replace the new one with a new one and the problem repeats. I read that I should do a bios restart. Will any of the honorable forum members tell you how to do it?

The easiest way is to pull out the bios battery for several dozen seconds, but I do not know if it will do anything

I have this problem with the T61:

The fan worked as it wanted, turned on once and not once. When he turned on, he was walking loudly, rubbing. I replaced it with a new one, the problem repeats, but when it turns on, it works normally. At startup, it turns on for a second, then nothing for 2 minutes, and then it turns on by itself, or when I blow it (with the computer open and turned on). Can this be set in the BIOS?

EDIT:

There are no options in BIOS, speedfan doesn't detect any fan either. What can you do with it?

EDIT2:

After several days of observation, you can see that when the computer starts to heat up and goes to high temperature, the fan starts up until it drops to a safe temperature. Can it be set to either walk all the time or try to keep to a specific temperature? I don't know where to find such settings.

Of course it is possible, e.g. with TPFanControl v 0.63. You set the temperature at which the fan should turn on in the .ini file or you set the manual mode

For me, the topic is still up-to-date, the fan has already been replaced twice in this model, half a year of calm and the symptoms are back - FAN Error. The laptop has successfully upgraded to the T9300 prock and 4GB of the frame and the performance is sufficient for my use in this configuration. Someone has information where to buy a proven fan replacement for the Lenovo R61i TYPE 7650-E6G model or, as a last resort, the original.

Half a year is not enough. Do how appears Fan Error and when you press Esc does the computer boot up and run?

Yes, the laptop works when you press ESC and when you put your hand you can feel that the fan is blowing but it is annoying because I like it when everything works perfectly.

Fan Error occurs when the cooling check system does not detect the fan speed, i.e. the fan cannot start up.
These exchanged are probably some cheap replacements? I once bought a replacement and it turned out that the blades were touching the bottom of the fan housing, it could not start and Fan Error appeared. I do not know where to buy a good replacement or the original, but that would probably solve the case.
Somehow I do not believe that something in the checking circuit could break down just like that, e.g. a resistor or something, unless from a lightning strike, as someone wrote in this topic:

there is just a FAN Error in the upper left corner. Apparently the house in which it was used was hit by lightning or lightning struck somewhere next to the house.

I bet that these are poor quality replacement - I don't remember, but the fan itself cost me about PLN 25-30 with the shipment. There is no point in returning to the website because it is a skin for a layette. It's a pity because the 3 paws were upped with the same prock and frame and everything is just the flawed one.

I have the same problem, but I have never touched the fans in my life.
do i have to go to the site or what? when I wrote to them, they wrote to me that they don't hear any problems.
what is it caused by?

For me, the fan has already been replaced with a noname, so far the laptop works quietly. Unfortunately, windows 10 is a memory-eating trash and only after turning off a lot of junk running in the background, it works somehow. The 7ka was much faster before. Laptop redrawn: 2.5 GHz T9300, 4Gb, disk returned to the disk because the Adata SU800 SSD crap broke after 3 months and further investments have already discouraged me. Future prospects - some light Linux - because generally these laptops, apart from the fan, are armored.
