Re: G550 fan problem

2010-01-07, 0:47 AM

Well maybe your post  is a bit harsh and will be edited, but your option with smashing the laptop can be done only if lenovo pay's me back. If that could be possible (hypothetically, couse nobody cares) i would accept it 0.1 sec after. This problem shadows all the positive things about this laptop.

So,  Lenovo solve this problem and erase this topic couse you're loosing customers. No one will buy a notebook (any kind) without searching about it. Guess what the ones that search lenovo g550 will find?

So Im found the answer. You can simply switch off the fan. Its only  solution to work with this notebook normaly. Simply dont use a hard task (e.g. archiving the files or something). 2 screw in the bootom of G550 and then pull out fan connector. Thats all.

All,

 

I understand the frustration over the cycling fan.   I would suggest not disabling the fan completely as cooling is important and if you unhook the fan and the system overheats we will have a new problem.

 

There are about 40-50 members on this thread complaining about the  fan cycling symptom and that is significant, noteworthy and has our attention.  

 

Typically, we need to have one or more systems that exhibit a particular symptom in order to effectively work an issue.  Sometimes we can reproduce the symptoms easily with a model we may have on hand, and in other cases, we need to bring in one or more examples from the field.   There are a lot of different systems and configurations and no, we don't have one of everything on the shelf.  Hard to imagine, I know.

 

There are several ways to help escalate this issue and speed the resolution.   If you are in the US, and have an example system that consistently, or at least repeatably demonstrates these symptoms and you would be willing to let us have a look at it, please shoot me a PM.   If you are outside the US, say in the UK, etc and you have already called service / support and have not received a resolution (obviously), then please ask that your case be formally escalated to level 2.  L2 may also like to see an example system and could work with you in your particular country.

 

In the meantime, we've reported the common elements discussed here to engineering, and I know they are investigating the issue.   Audio files and other information is helpful in demonstrating the symptom and I appreciate those being posted.

 

As to the design of the heatpipe / heat sinks.  I compared the G550 with intel graphics to several of our Y550's that use a similar single heat pipe and fan.  Y550 customers have not reported these symptoms, so I'm not sure I agree that there is a problem with the design.  It certainly seems like it is most likely a difference in the BIOS and the fan step points as several members have suggested.

 

What BIOS version  is installed on your systems now?

 

Mark

I don't think the design is bad, design is classic. Yes, some notebooks do use two heatpipes, but this is a value line... The reason why systems with nVidia graphics are generating "much" more heat is because the cooling system (heatsink) is small, it is tryin' to run passively and in this case only 1 or 2 watts more will rise the temperature significantly. Simply, heatsink is too small to cool down the system passively, but it does turn off the fan. The only bad thing is the fan regulation, it should be runnin' on the slowest possible speed that can keep the temperature stable when system is in idle. And it can have some hysteresis or/and smoother speed changes like for example new ASuSes have.

BTW: how many BIOS versions are there for G550?

BIOS Version/Date LENOVO 18CN37WW(V2.10), 9/18/2009

Maybe the problem is only for those made for europe. Most of the users who posted here are from europe.

Try getting one with nvidia graphic card. The simptoms are more likely to apear ( i think it's imposible not to).

Or maybe an older version of bios would be a solution.



Thank you mark for taking interest.

Re: G550 fan problem

Bios Version : 2.10

 

I bought the G550 with the T6600 and G210M last week, but in the first hours of using I didn't recognize the fan problem. Unfortunately I am used to have those "problems" with my mobile devices. My Acer Aspire One still needs a fan control tool written by a user, because Acer still didn't take care of it. Same with my Fujitsu Siemens M3438G - the fan was running and running changed to silence just to start running again ;-).

 

I don't think, that the G210M or the case design is the problem. Why? My old M3438G got a 6800go with a mush higher power comsumption in idle mode than the G210M. The Temperature NEVER went below the 65°C line in idle and crossed the 90°C while playing games. The G210M does not even reach the 65°C while running Mass Effect and the heatsink got the same size like in the M3438G :D (yes, that notebook got a total fail design).

 

Also the processor shouldn't be the problem. 

 

I think that this fan problem could be solved by software if we had the right register address to write the fan speed values into it - if i saw it right, we know which speeds are supported reffering to the ThinkPad tool.
