Re: X220 - fan constantly on / revving up and down

2011-07-21, 1:27 AM

For those of you who send out your X220 for repair, how long has it been taking for you to get it back again?

@All,

 

For those who has BIOS updated to 1.19. Do upgrade the Power Manager to 3.62 as well.

I will be reporting back wether it's been fixed or not.

 

According to the tech people it will take the servicecenter a maximum of 5 days, my laptop was picked up yesterday by UPS and I reckon it will be another week before I get it back. I got my slice battery and extra memory ready to be installed along with an SSD and a gentoo distro so looking forward to getting my new X220 back.

 

@JameZ, why do you need a 'Powermanager' Window specific program to eliminate the fan pulsing? It does seem kind of odd, I haven't really been having any problems with pulsing of the fan, just the whine (the pulsing is very very slight as I have previously mentioned), and I am running Linux.

So it's actually OS specific? Why not just let the BIOS control the fan completely, seems to be the most stable, easiest and reliable method (data-tech engineer speaking).

Did the updates actually fix anything for anyone?

 

The pulsing was really apparent with BIOS v. 1.16 on my X220T - so much so that when I first heard it I thought the fan had become unseated and was knocking against its housing. You can actually feel the pulse when typing, which is extremely disconcerting. The updated BIOS didn't do much for my X220T. It moderated the strength of the pulse, but didn't actually get rid of it. I'll try the updated power manager and see what happens. FWIW, the problem really shows up when I use the "Power Source Optimized" profile on battery power. I've modified my profile to bump up the CPU performance to "Balanced" and the display brightness a bit. I'm curious what triggers the pulsing for you guys.

 

On top of that, my fan does whine. Unfortunately I have no other X series to compare against (any pointers?), but it's pretty annoying. My work provides me with a MacBook Pro, and although its fan gets going when you stress it out it doesn't have that high-pitched sound.

 

Are the fan problems hardware or software related, and do I have to send back my X again?

 

Oh - and my machine was also manufactured on 11/06. I don't know if we can make a lot from that - it was probably the first run - though I'll probably never buy a first-run unit again.

 

Update:

 

The latest Power Manager doesn't help. If anything, the situation is worse. When the laptop is plugged in with no activity the fan runs full blast in a cool room. The laptop makes a buzzing and static-y noise.

sojoe02 -- what service level do you have? I have the "return to depot" and when I called Lenovo tech support they just said to me, "You either need to pay to have it shipped to our service center or else use one of your local service centers listed on the support website." When I started calling around to the "local service centers" on the website (http://support.lenovo.com/en_US/product-service/service-provider/default.page), none of them provide warrantee service.

 

I don't know what it's going to cost me to send it back to Lenovo, but I imagine it will be expensive. However, if I send it back today, and it only takes five days, I can have my wife bring it back with her when she joins me on August 6.

JameZ -- First of all, I want to say that I really appreciate your patience in these forums. It's encouraging to have you weighing in here and helping to get problems addressed.

 

I did try updating to 1.19/3.62. What settings do you want me to run in 3.62 to test? I restored the various profiles to default settings and the pulse is still there.

 

If the fan wasn't whining (which is sort of a quiet but high-pitched whine, like a mosquito), I wouldn't hear it. I have other laptops, including a tiny ThinkPad X40 and a behemoth 17.3" HP DV7t Core i5 with big fan power, and neither of them have this whine. Even though the fan is only putting out a fraction of the air that the DV7t puts out, the whine makes it louder than the DV7t and leaves my ears ringing when it stops.

@audioenthusiast : I have 3 year regular warranty, perhaps the companies warranty policy differs depending on region. I bought my X220 in Germany, because of the educational discounts you can get there. 
The service time is the same here 5 days, and it's actually being sent back to Germany as lenovo apparently doesn't service their machines locally.
The whiney sound is exactly like that of a mosquito, very annoying I dont think it affects hearing as the sound pressure is far too low for that, however it does imprint itself into the mind. Btw my Lenovo X61s, also have a high pitched sound from the capacitors, and its not a problem for me at all.

@allengeorge -- I can feel the pulse under the keyboard as well, up in the the top-left quarter of the keyboard, above the fan. And I would also agree that it's disconcerting.

I realllly want to get rid of this whining noise, but I am not crazy about the idea of sending it back to Lenovo for $?.?? and then having them send it back with the same fan and an "updated" BIOS (I have the most current BIOS installed already, but several posters have said that all the techs did was reinstall the most recent BIOS).

What utility are people using to read the fan speed?

 

Looking for something that preferably doesn't need to be installed and can run standalone.
