Could someone upload a video with a good sound to let me hear what happens with your fan? I understand that the problem is not fun, but I would like to know this because I have no experience with laptops and this is my first notebook.

Re: G550 fan problem

The thing with this notebook is that that the fan cannot be controlled. It has only 2 speeds: Low(almost off) and high(full rpm). I'm not an expert about this. I cannot even believe how someone could design  something like this nowadays. Why don't they fix this? It is beyond my reach. I encounterd crappy  Intel Prescott mobo's behaving like this: fan going on and off sudenly with no intermediate rpm states. This is the most anoying thing. There should be other states than 0 rpm and maximum rpm. Maybe there are, I do not know. They must give an official answer . It doesn't matter, Lenovo must give an offcial answer ASP or the entire reputation that they've just bought from IBM is going to the garbage.

Someone please correct me if I'm wrong!

This is my last post here. The next one will be only regarding the results of the bios fix, I hope. I've just tested it. It doesn't matter what OS you are using because their power management software doesn't control the fan. Let's hope that the BIOS can control the fan rpm, otherwise their will be no fix for this. I've tried Windows Xp, Windows Vista and ubuntu latest version and the same result. I repeat myself for the last time in the hope that people responsible with the support of this product will read this: The problem is not the noise that this fan makes at full RPM but the fact that it changes from almost 0RPM to maximum RPM very very fast and it does that very often and constantly.

 

JHP's post is the most acurrate one:  Here it is once again:

It made no difference whether I was using battery or AC power.  While using IE8 to surf the net or watching a film or listening to MP3s the fan would start cycling at intervals of about 20 to 40 seconds, remaining on for about 30 to 40 seconds at full-blast each time.  This would happen within 15 minutes of switching on the laptop from cold.  It seems the fan has only one speed and that temperatures are being controlled by it being either on or off.  I'm sure you can appreciate how this would become intrusive after even an hour.

 

Here are my detailed system specs:

bought a few days ago

Name: Lenovo G550

Model: 20023

M gf Date: 09/10/21

S/N: ***

Bios version: 18CN37WW (V2.10)

Bios date: 09/18/2009

Cpu: intel T4300

Memory: 3GB DDR3

HDD: 320GB, Hitachi

Video: intel gma4500

OS: FreeDos, preinstalled

 

Tested on Windows Xp( the OS that I'm  using and will be using on this machine), Windows Vista and ubuntu 9.10. On windows I've used only the drivers provided on the Lenovo website for this model.

The notebook faces the same issues as described by JHP on every OS.

JHP,

 

I can see that this discussion has grown significantly during November and we can certainly look into this.

 

Would everyone agree that the fan behavior apears to be the same regardless of OS?

 

Any differences when the system is run on battery or AC?

 

I'm re-reading the thread, and understand the general fan cycling too often / going to high speed complaints.  I'm just looking for some details to include as we test some samples to try to reproduce what is being reported here.

 

Thanks!

 

Mark

 

 


 

Don't worry guys, Mr Lenovo (Mark_Lenovo) has been looking into this since the 1st of December 2009, which is when he wrote the post above.  He's obviously way too busy testing G550 fans to have the time to tell people when this design fault will be rectified.  In the mean time, G550 owners should just follow Lenovo's example and stick their fingers firmly in their ears and pretend everything is just fine.

Re: G550 fan problem

Hello, my English is not the best. I also bought the G550 (T6600, G210m) one week ago. Experience is exactly the same. Laptop super, but noisy operation. Constantly use fan, switch on/off  20s/60s, 0% RPM / 100% RPM. However, CPU or graphics have no load. Setting this can not be changed.

 

I found out about G550, everywhere it is written, but no solution has not. Manufacturer silent. Today I called the Lenovo Czech hotline. Technician would confirm that the problem is known and that working on it. Problem is in the BIOS, prepare a new BIOS, which should eliminate all. Lenovo Czech is in contact with someone from Lenovo, which appears here on the forum under the nickname Mark_Lenovo. Written email him again today, asking to have fresh information for me. He told me if it is possible to wait a few days.

 

My way:

I have the opportunity in the test period of 14 days to return the laptop. It also will. I do not like how the Lenovo deal with the problem. I have no confidence that the solution will be found soon. I will buy the laptop of another brand that does not have this problem.
