    This looks really great so far. One problem I noticed is when using 1024×768 resolution and downscaling, the mouse pointer has a rectangular area filled with garbage pixels following it around. Could be related to pointer shadow? Is this a known issue?

  • 4. Noda  |  November 10, 2008 at 9:35 am

    Strange, never heard of this issue wil downscaled 1024×768 mode. Maybe you should try udpating your video drivers? Or maybe it’s related to your cursor set? I use pointer shadow without problems on my A1 with downscaling.

    I love this utillity it works great. Is there also a linux version?

  • 6. Noda  |  November 12, 2008 at 1:18 pm

    No linux version is planned for now, as this soft uses the win32 API everywhere…

  • 7. audrik  |  November 14, 2008 at 4:26 am

    very very good utility. Is it possible to make it a little more speed boot up?
    Can you Add an option to make our slow power option, with possibility to select if webcam, ethernet, wifi are activated or not automaticaly when A1 is on battery?

    Thx a lot and great job

  • 8. Jeremiah  |  November 17, 2008 at 5:20 am

    This is so cool! I love being able to quickly switch to 1024×768 when I need to. Next time I have some money I’ll throw a little your way. Thanks!

  • 9. Phil  |  November 18, 2008 at 8:27 pm

    A great tool!!!
    Is it possible to make a overclock option?
    you did a great job 🙂

  • 10. rob  |  November 19, 2008 at 10:49 pm

    great soft, i´m using permanently on my aoo, but for some reason the fan control speed/turn off does not function. Last day i leave the option on “custom” (this is how it contros the fan, right) and the fan never turn on while my temperature was up to 66º.

    My setup is this (all chequebox selected):

    stop fan under: 50º
    start fan in slow mode at: 60º
    start fan in auto mode at: 65º

    so, right now i hava to use the “fan>auto” mode to prevent hight temperature.

    this was not happending at first, i do not update drivers or install any other soft like this or anything strange….

    any ideas?

    anyway, great soft man!!

  • 11. rob  |  November 19, 2008 at 10:53 pm

    ah!!! could be posible that if you change values, they don´t take real effect till re-boot the machine??

    i mean, let´s suppose my temperature is on 51º
    and i have configured to stop under 50º, what happend if i change the value to stop working under 52º? in theory if i´m under 52º fan must stop, right?

    i did it, but the fan did not turn off, so what i think is that the soft is not taking the changes about fan in real time or something like that…. i´m wrong?

    have you experienced this?

    thanks again

    A good app, perfect for my AAO, but the config button dont work and crash the app.

    I edit the a1crt.ini file and it works perfectly.

    My temp settings are this:

    stop fan under: 70º
    start fan in slow mode at: 72º
    start fan in auto mode at: 75º

    Atom N270 auto stops at 125º (see intels datasheet), I think it works perfect at 90º

    So, thanks for this job!!

  • 13. Noda  |  November 25, 2008 at 8:34 am

    rob> that’s because it takes some time before the parameter may be applied (~30s), and because internally the temp may vary more that what is shown on the icon (the icon may display 51° while there could be small jumps at 53°, causing the fan to not stop).

    Also it seems from other comments that some AAO have a new EC (Embedded Controller) chip that prevent a1ctl to work, I’ll try to investigate for this one but I can’t promise anything since I don’t own one…

  • 14. roflballs  |  November 25, 2008 at 8:57 am

    Just a comment/suggestion about the next version of the app.

    Since you were able to get 1024×768 to fit on the screen with downscaling, do you think you could add an option for 1280×768 with downscaling as well? I feel that this option would have a lot more use than just fitting 4:3 inside a 16:10 screen. Having greater desktop space is a function I would really like, even if the image gets blurred a bit.

    Thanks alot!j

  • 15. beaudroit  |  November 25, 2008 at 6:12 pm

    very good software

    with have XP in to install

    Are you going to do an update that support the latest BIOS version?


  • 17. Noda  |  November 27, 2008 at 4:34 pm

    I think that’s not needed, as some users reported it works fine with this bios. But I’ll definitely release an update when I find some time to fix some issues.

  • 18. Dirk  |  December 8, 2008 at 4:14 pm

    Great work! At the office I connect to external screen with resolution 1680×1050. Is it possible to add that to the list of resolution preselects in config feature of file?

  • 19. Basileus  |  December 12, 2008 at 4:33 pm

    Great job! Thank you for creating such a great and helpful tool. The only minor nitpick I have is the border style of the About dialog should be set to Fixed Dialog instead of Sizable.

  • 20. Tom  |  December 13, 2008 at 1:26 am

    Very nice but seems to only work for Admin accounts. Is there a way to allow users the access to IO?

  • 21. Noda  |  December 19, 2008 at 8:44 am

    I’m not sure concerning this admin problem, but if I remember well you have a possibility to run a specific program as admin on a restricted user account on xp. That may be the only way as I/O access require higher privileges.

  • 22. sty  |  December 21, 2008 at 5:33 pm

    Great job ! could you explain what CPU cpu throttling is please ?

  • 23. sty  |  December 21, 2008 at 5:36 pm

    Oh and I forgot one thing, i think that on my AO the slow mode isn’t working since I can’t ear the difference between when the fan is off and when it is on slow mode. Auto mode works fine though.

  • 24. sty  |  December 21, 2008 at 6:18 pm

    sorry for the triple post but I found out why the slow mode isn’t working: it’s because the Off mode activate the slow mode and the slow mode activate the off mode lol
    by the way i’m using windows xp sp3

  • 25. Ralph Bacon  |  December 31, 2008 at 6:32 pm

    Excellent bit of software – two for the price of one! Works just great on my AAO 150.

    Donation via PayPal made, pity the exchange rate is so low.

    Happy New Year!

    […] Hier habe ich ein kleines, etwas unbekannteres Tool zum Ruhigstellen des AspireOne gefunden: a1ctl […]

  • 27. Dieter  |  January 8, 2009 at 8:09 am

    Great Tool – you did an execellent job!!! Thx

  • 28. Oscar  |  January 20, 2009 at 7:09 pm

    I have installed under the lastest bios3309, it works ok?? what about compatibility, thanks a lot.

  • 29. lu1u  |  January 22, 2009 at 7:17 pm

    What custom fan settings should I use ?
    I set “stop under 50°C”, start in slow mode at 60°C, start auto at 65°C and the fan is making a lot of noise even when the tray icon display 37°C

  • 30. floehchen  |  January 24, 2009 at 5:51 am

    It seems this great litte tool has a promblem with Windows 7, I’m getting an error: ‘MSCOMCTL.OCX missing’.

    Do I have to install a special runtime für win7?

  • 31. Rashid  |  February 12, 2009 at 10:29 pm

    Hello there
    Just to inform that it is working fine on Windows7.
    I am running AOA150 with 512MB ram and temp is around 47-52C while browsing this site with firefox3.

    How I did it?
    Download MSCOMCTL.OCX off the net
    placed it in Sysmtem32 folder
    RUN comman prompt “Run as Administrator”
    Type “regserv32 \windows\System32\MSCOMCTL.OCX”
    Right click on A1CTL.exe and check “Run as Administator”


  • 32. Rashid  |  February 12, 2009 at 10:39 pm

    Sorry just realised there was a mistake in previous post about registering MSCOMCTL.OCX

    Wrong Syntax: regserv32 \windows\System32\MSCOMCTL.OCX
    Right Syntax : regsvr32 \windows\System32\MSCOMCTL.OCX


  • 33. Mike  |  March 7, 2009 at 4:43 am

    Thank you. I donated $20 and hope Acer pays you too. If not for your tool, Acer would be refunding my purchase price. I had a dozen programs that would not work in the x600 resolution. Photoshop Image RAW, Quickbooks, Eagle Soft Practice management won’t run without your fix. I wrote a Wiki page on your app.
    Thanks again.

  • 34. David  |  March 19, 2009 at 11:33 am

    Works perfectly with the Packard Bell Dot too 🙂

  • 35. Helmut  |  May 19, 2009 at 7:43 am

    Hi, I’m German.
    My question:
    Is it possible, to install this program on an ACER Aspire One A150L (the version with LINPUS-Linux)????
    If so: HOW?

  • 36. Norvey Arredondo  |  June 3, 2010 at 1:11 pm

    Gracias por tu apoyo

  • 38. g  |  July 16, 2016 at 11:23 pm

    I this is really old. Did it ever work (fan control) on the Acer Aspire One D150. It never seems to do anything for me??? Thanks.
