chirping fan on 5680 - Page 4

ok guys, here is how it works.
The embedded controller is an extra cpu on the mobo from the Renesas (formerly Hitachi) H8S family that runs with a clock speed of 10 MHz. The purpose of this cpu is that it handles the keyboard, touchpad, PS2 connector, batteries, temp sensor and fans. So it isnt really a "keyboard bios" but a "embedded controller firmware". This design is actually quite clever (and a must), because it not only relieves the cpu from doing this, but it is a safety because it handles these important things like fan control and control battery charge even when the main cpu is in standby. The drawback is naturally that the control is hidden away from the main cpu and therefore also the user. Thats why no programs like motherboard monitor can read the temp sensor. So what I did in my temp sensoring program was to communicate directly with the EC. However, in order to control the fan speeds I have to dig even deeper. I have to actually reprogram the EC firmware. This is not a thing to do for the fainthearted, but I know what I'm doing. I dont have a 5680 so I havent flashed this updated firmware, the latest for the 5660 is 1.00.16 which is the one I'm modifying. And yes, I'm sure it returns the Ctrl and Fn keys to their original positions.
Cool stuff! I always considered the design a negative factor, but now I got to actually appreciate it. Thanks for shedding the light, Henrik!

I contacted Sager tech support yesterday with the hopes of receiving the firmware flash, but no reply as of yet. I suppose that means that they could be ignoring me or just off for the weekend. That would be seriously disappointing if we are unable to get any tech support on weekends.

Uh...because computers break on weekends.

You sound as if working on weekends is a big deal. It's not like they provide active support anyhow - they just return emails. Every single major computer company out there provides support on weekends (often 24 hours a day).

This issue doesn't require any justification from me - if they don't provide support on weekends, that's subpar, period.

I somewhat agree with teddycamao but I wouldnt call them bad just because of this.

Yeah, I'm not saying that they're bad necessarily because of this - just that in this matter the service is subpar. In other ways they may be (and certainly seem to be) better.

Update -

I got the updated firmware this morning. As others have reported, I have yet to hear that accursed noise anymore. It would cause me great joy if things continue this way.

Followup: been running with the new firmware since Friday, and haven't heard the chirping again. I think it's well and truly gone.

As a follow-up to my previous post, I have managed to change the fan speeds manually. The speed can be varied from 0-100 percent, and at some speeds it makes this sound. I think you can be sure not to have the sound anymore after applying the update.

Hey guys, the fan noise is taken care of with a new KB firmware flash. If you did the fn/ctrl key swap or are doing the swap, download the updated file from this post:
http://talknotebooks.com/showthread....&threadid=7157

OR if you didn't and aren't doing the fn/ctrl key swap, you can download THIS one. Let me know if you have any problems.

Yet another update -

I installed the update I was emailed by Sager, but this morning the accursed chirping was back.

I went ahead and installed the updated fn/ctrl swap firmware that Adam posted...hopefully that will work.

Ok...2.5 days later, the firmware update seems to be working great: no chirping, and I was even able to use my laptop in a quiet meeting without qualms.

Beachbum - if the chirping is going on, it's irritating; I'd be embarrassed to use it in a quiet setting with other people around. However, in other situations the fans are very quiet. As this is my first laptop, I can't directly compare the noise to other laptops, both many others have posted that the noise level is less than most, and I'd believe it. Since this latest update seems to have resolved the problem, you shouldn't have any worries about the noise pollution of the 5680.

hi,

I bought my 5680 two month ago, do these models still have the issue? I'm wondering, because I have something like that, I think
But I think that they already fixed that issue. So I shouldn't have this issue?
