Timeline Constant Fan Anomaly

Owners of Acer Timeline series notebooks have been reporting the fan running constant in power mode.
Even though the computer is running cool, and there is no need for the fan to kick in. The fan does not run constant in battery mode.

I purchased the 3810T su3500 version and I have experienced the constant fan issue myself.
Plug into power and the fan starts. Unplug from power and the fan stops.

Sadly for this reason, I returned the laptop since my reason for purchasing this computer was for silent operation.

The Acer Timeline computers at the store are plugged into power and I can not hear the fan running at all!!!
I checked another store, and again, the computer is plugged into power and I can not hear the fan running!!!

First I thought, the noise levels of the store may overcloud the fan noise, but then I noticed, that both of the computers I checked, although they were plugged into power, neither of them had the battery plugged in!!!

Test this out and report your experience here please!

Take out the battery while plugged into power. This may solve the constant fan anomaly.

 

When I take out the battery when plugged into the power, the fan is still there. However, it is extremely silent, and a lot more silent than when there is the battery plugged in.

It does kick in once in a while though, before returning back to very very quiet levels.

Oh yes, if it matters, I'm always running wireless. (Because I read somewhere someone complaining that the fan is always on when wireless is on)

 

I am sorry it did not work out

The noise levels of this computer is beautiful running on battery. If only there is a way to trick her into believing it is on battery while plugged in.

I don't suppose Acer has added a feature in there newest BIOS for disabling constant fan.?

If anyone here discovers a hack for this, please be kind enough to report back here.

I have tried contacting Acer about this issue, but they did not even bother reading my email, telling me to provide a correct serial number other than zero's.. Well I would like to buy another serial number if they acknowledge this issue.

 

Personally, I don't think it's such a major deal although different people obviously have their different opinions, which they should be rightly entitled to.

I believe that it isn't such a major issue because the fan overall is quite silent, it's not particularly intrusive.

 

I have the exact opposite problem. I think my fan doesn't work at all, because I can't hear it and there's absolutely no air coming out of the vent.

The CPU temperature usually rests at about 55-65 Celsius.

How do you know your CPU fan starts? Do you hear it or feel the air coming out of the vent?

I also tried SpeedFan but it doesn't detect any CPU cooler.

 

Was the fan really that loud when plugged in? On mine the fan noise is so low than you can't hear it unless you put your ear right next to the vent. Standard background noise is louder than the fan when it is plugged in.

 

My fan is loud. I keep the battery out when plugged in and the fan in constantly running. When I turn on music or a video, that overpowers the sound of the fan. Hopefully when I get a ssd next year, the fan noise will stop.

BTW, mine is undervolted. Hopefully this is the last computer I buy with a fan. When I'm ready for a new on in 3.5 years, I hope fans are dead.

 

this app should do the trick http://forum.notebookreview.com/showthread.php?t=421850

 

hmmm..........thats weird ...but in my 4810t fan sound is very low even in power mode...

 

I will say that I'm running the "1810 tray" prog on my 1410 and set the hold temp to 52c and unless I'm pounding the CPU the fan stays somewhere between off & unnoticeable : )

 

The fan in my 4810 with 1.15 ver bios only came on once in a while. I have now updated to ver 1.30 to get the brightness to work via the Fcn key and now the fan runs contantly. Acer will no longer supply the ver 1.15, I am just wondering if that was a power saving feature to get it to run 8+ hours. It only runs 6 or so hours now

 

I'm not by any means on all the facets of power management but could not the policies with respect to cooling be adjusted to passive (as it is in battery state) rather than active??? Would this work?

Or how about adjusting the minimum processor state to 5% when plugged in as it is in with bettery state rather than the default 100%?

Any experts or thoughts on this?

 

You can try and set System Cooling Policy to control the fan behaviour.
I am not sure if Acer Aspire 4810 obeys the new Windows ACPI System Cooling Policy behavior.
You can try setting it to passive so the fan MAY spin up less.
