BIOS v.3114 - fan, heat issues

Hmm... After upgrading to the v.3114 BIOS the fan is constantly on and I think the air from the exhaust on the left side is a bit warmer.

Before the upgrade, the fan was almost whisper quiet but after upgrading to v.3114 my fan is quite noisy and always on. Are you experiencing the same symptoms? Since the earlier BIOS is not available I can't roll back and verify this.

A110, 8GB P-SSD1800, Linpus plus the latest Live Updates.

 

Yea I just got mine the other day and noticed that the fan is always running I found it kind of odd, are there any programs you can throttle the fan down that are windows based?

 

Have you checked that the processor speed was still dynamically reduced to 800MHz when usage is low, as it's supposed to be ? If your proc is constantly running at 1600 MHz, that might explain the heat and therefore the fan noise.

 

How do I go about finding that? I use a mac as my regular computer and have forgotten several details about windows (im a little rusty)

 

Well sorry I don't know about Windows, but on my Linux distro (Xubuntu), you get a plugin which displays the proc frequency. Maybe you can get a similar utility for Windows, I don't know.

 

CPUID CPU-z will tell you Proc speed, and it sees the atom.

You might want to try HW Monitor

Mine is the 150-1570 and I see mine spin up and down. I haven't upgraded the Bios. The Proc speed does jump.

 

If you're using XP, you may want to check in the power control panel to see what scheme is active. If the "Always On" scheme is on it'll disable SpeedStepping.

Set it up to "Portable/Desktop" and the throttling should work again.

You can check your speed in the system properties by pressing the windows (or house) key along with the "pause/break" key on your keyboard.

 

Any way to go back to the old BIOS?
this fan is really annoying. :cry:

Linpus 8GSSD 4GSDHC 512M

 

Same issue after BIOS upgrade. Fan speed is now always on highest. CPU is 800 MHz ( grep 'cpu MHz' /proc/cpuinfo ). This is very annoying.

 

My Fan's on alll the time too after 3114 bios update. I updated because I had some WiFi WEP issues. I wished the the update made a backup and asked for confirmation first before starting the upgrade.

I had a look at the flash utility and you can make a backup with it. Any one still have a older BIOS (Probably 3109 ) out there willing to make a bios dump ?
To make a backup follow the make BIOS instructions. But instead of running the BAT file type the following at the command line:

FLASHIT ZD5_3xxx.FD /AC /G

This will dump the BIOS to the file BIOS3xxx.FD and won't nag about a missing AC adapter. Please replace the 3xxx with your bios version. You can find it on the Setup information screen when you press F2 on bootup.

Thanks.

 

Thanks for the help, the fan is still running on high, but it is lowering the cpu speed to 800mhz when doing minimal task I am sure Acer will release a bios update to fix this issue soon (I can only Hope)

 

Blinky, I have done as you asked, where do you want the old BIOS, the forum says the file is too big, Will try and pm it to king?

 

you could prob upload it to here and just post the link of the old bios rom http://www.filedropper.com/

 

I emailed it to King, it will be online soon.

 

Is there a fan control util that can be used for the AA1? When I had my eeePC 701, there was a wonderful app that allowed me to control cpu clocking and the fan in the system tray, wonder if there is such an animal for the AA1's.

Here's a dump of 3109 bios from my 110L.
Hope it helps

bios 3109 dump

*edit*
I am having problems with restore from this dump. Bios was dumped as discribed earlier by someone else.

I got 2 one's though, and I noticed that after updating to new bios, more heat comes out than in 3109 bios... but might be something else than bios related.
I'm running linux on both mashines.

 

thx sid, older 3109 bios here - http://www.humyo.com/240597-160432785

 

Happy to help.

 

Thanks for dumping the bios ! what problem did you have when you tried restoring the bios using that dump ?

*EDIT*

I noticed the dump checksum fails. :-(

 

Thanks for uploading the old BIOS. Are there any reports yet on reinstalling it?
v.3114 did not make much of a difference to my machine but the fan is now always on, so I would like to go back.
