On upgrading an AO522-BZ499 Netbook

First of maybe a few tech posts. Some of you that know me are probably surprised my first posts weren't that geeky to start from. Anyway, I decided to do this one because there isn't that many posts on the web regarding that specific model. I'll skip the tech spec saying this is a great little netbook powerful enough to play 1080p videos (the monitor is only 720p, but it has full 1080p output through HDMI out) and good battery autonomy (around 6-7 hours).

The major downside to this computer are that it has only 1GB or RAM of which 256MB is taken by the GPU; given that it runs Windows 7 Starter, that doesn't leave lots of headroom. I therefore decided to upgrade it to 4GB of RAM (not much pricier than 2GB so why not!). Since Windows 7 Starter only supports 2GB or RAM, I also decided to upgrade it to Windows 7 Home Premium (got a deal on the Anytime Upgrade ... 20$).

So, for anyone interested in the procedure, here is how it went.

Step 1 - Removing the keyboard
In order to remove the back panel of the AO522, you need to remove screws that are located behind the keyboard, so lets remove it. To do so, you need to first unclip 4-5 little plastic clips on top of the keyboard (see picture below).
If you have a small solid plastic tool to do the work, good idea to use it as you have less risk of scratching the surface ... I used a small metal flat screwdriver; damaged the surface a bit, but it is barely visible and could probably be hidden with a black Sharpie pen. When you push the clips back, you might want to gently pull the keys up so the clip won't pop right back into place.

Once you do it with all the clips, they keyboard won't pop right out, you could try to pry it a bit as some online video suggest, but I have an easier solution. Remove the battery at the back, there will be a square opening on the right (see picture below), if you take the eraser side of a pencil and push, the keyboard should just pop.

Step 2 - Popping the back panel
Once the keyboard pops, you could remove it completely by unplugging the ribbon, but it isn't necessary. Once you have access to the back of the keyboard, you will see 4 screws marked with the number "1" (circled in red in the picture below). Unscrew them, then push with a thin object in the whole next to the HDD (marked with a star in the picture below). I would also like to point-out the dent in the back of the keyboard (red arrow in the picture below), that is where I pushed on the keyboard with a screwdriver instead of a pencil eraser (and why I suggest a pencil eraser); the material is very delicate, reminds me of BBQ grade aluminum foil. Damaging it a bit doesn't seem to cause any problem at all; it didn't pierce through, just dented it, but you could have done the same with the tip of your nail as well.

Step 3 - Now we change the RAM
To change the RAM, just stick-out the 2 little metal "arms" on each side of the DIMM, the memory should pop right up and you can remove it. Place the new module in and push back down. You might have to move the "arms" to fit it back in.

Step 4 - Check and close the netbook
Now, before closing everything, make sure the netbook boots and detects the memory by going into the (very limited) BIOS and in Windows.

Now you can close everything; put the back panel in place, re-screw it, put the keyboard back. You are now done!!!

Step 5 - Upgrading to Windows 7 Home Premium
The upgrade to Windows 7 Home Premium is supposed to be pain free and it is ... sort of. Simply bring-up the Anytime Upgrade application (type it in the start menu), enter the key found in you upgrade box and follow the steps; easy. When I did it, I got an error message telling me the upgrade failed, crap! Then I rebooted, but by doing so it finished the installation and everything got upgraded like that. I don't know what failed, but it gave me a scare there; might have been because I already had SP 1 installed.
Yup, the upgrade is just that, a piece of cardboard with a code on it.

Conclusion
The process was rather trouble-free and now my netbook is much snappier than before, the Windows Performance Index for the memory when a whole 0.9 point up. For those wondering which RAM module I used, it's a G.Skill F3-10600CL9S-4GBSQ.

  2. did you upgrade to 64bit win7?

  3. Jon, a 32-bit Windows 7 OS can only be upgraded to another 32-bit Windows 7 OS. If you want to switch to a Windows 7 64-bit OS, you'll have to do an install from scratch.

  4. Thanks for the instructions!! Great help. I would have been lost without it. Everything went smoothly. The only thing was that my Acer does not seem to have the hole in the battery slot for pushing the keyboard out. I just had to gently pry it out.

    To the instructions I would add that when you push in slot by the HDD (after removing the screws marked with a '1') make sure the netbook is elevated a bit as this allow the panel on the bottom to pop out. Being a NOOB i wasn't sure what was supposed to happen when i pushed in that slot.

    Also I used F3-10666CL9S-4GBSQ memory (just because it was available locally).

  6. Hi, thanks for the great review u gave here ;)
    I have a question, can I use the Corsair CMSO4GX3M1A1333C9 4 GB ram instead of the one that you used currently? what is the different? I am a newbie..appreciate your feedback.
    Thanks

  7. stuck at step 1, i removed all the 4 clips. I realized i dont have one clip at the furthest left, it's just nothing. but when i removed 4 of the clips, i cant lift up the keyboard. something seems to be stuck at the right side. any idea?

    ReplyDelete
  8. Thanks a million. This guide really helped me. I had a hard time getting the keyboard off... I was just being too gentle. :P

    Just installed 4GB Corsair CMSO4GX3M1A1333C9 and all 4GB are detected by the BIOS. Next step... replace OS to use all 4GB.

    Cheers

  9. Sorry all for not replying before, I just realized that by default Blogger doesn't send email notification of comments.

    Non I didn't switch to 64 bits yet. I was mostly using the Netbook for classes so I didn't want to much downtime.

    Moreover, I'm still not sure how I can proceed since I got an Anytime upgrade license and Windows 7 starter is only 32 bits.

    Yes, the netbook only has 1 slot of RAM and therefore is limited to 4GB. I don't see any reason why you couldn't upgrade to a 64 bits OS, but bear in mind that you cannot "upgrade" from 32 to 64 bits, it needs to be a clean install.

    If the RAM module has the same specs (speed, voltage, CAS latency, ...), it should work, but I know some equipment can also be very picky.

    I think there are also some small notches holding the keyboard on the sides close to the top, but you cannot push them like the other, you just force them out as you remove the keyboard (educated guess, be careful).

  14. Great Guide :) Just installed Kingston 4GB CL9. Worked for me except one thing - popping keyboard. In mine AO522 there wasn't any sqare popping thing. just had to gently take keyboard out with my hands ;)

  15. Hello. If I decide to upgrate to a 64bit version of Windows. Where do I get the 64bit drivers? On the official site, there are only 32bit only.
    MANY THANKS and GREAT POST!

  16. @NicK2oo6
    Mmm, I could swear they once had x64 drivers in there, but it doesn't seem to be there anymore. Have you tried contacting Acer to ask about it?

    ReplyDelete
  17. Yeah, just a few minutes ago. Waiting for a respond, I`ll post it here if you want to. Can you help me in this case with some drivers? Thanks for your kind and fast reply.

  19. Oh yeah, I can still stick with 32bit version since the graphic card uses 256mb of ram, so, Windows 7 Ultimate will do the job or what win do you recomd me fro 4gb of ram - 256mb(video memory)

    ReplyDelete
  20. @NicK2oo6
    By using a 32 bit OS, you will possibly loose the use of about 512MB of RAM; I use Home Premium 32 bits and have ~3.2GB usable after the 32 bits limitation and the 256MB video RAM.

    As for which version of Windows to use, it just depends on the features you want/need. Home Premium is more than enough for most people; Professionnal adds the support for XP Mode, remote desktop, network backup and joining domains; Ultimate adds (on top of Pro) drive encryption and language pack support.

  21. Uhm, I see, but the use of ram/cpu what is the difference between Home Premium and Ultimate? Wich version works and uses less resources? What do you think about upgrading to 64bit? Can you help me finding 64bit version of drivers?
    Thanks

  22. @NicK2oo6
    I'm pretty sure Home Premium uses less resources as it has less features, but the difference might not be much.

    As for 64 bits, I will try to find drivers (tonight), but you will notice the only one you might actually need is the Audio driver, the other drivers are for 3G and BT which your model might not even have (mine doesn't).

    ReplyDelete
  23. Drivers for CPU/motherboard/video/WIFI/wLAN ? Or the Windows detects all of them and the only one that it can`t be found is audio driver?
    Thanks and I really apreciate your kindness.

  24. @NicK2oo6
    The Acer website says "This page shows only drivers that are not contained in Windows 7", so I would assume the rest is detected by Windows 7. Might want to confirm with Acer too.

  25. Hi I have the same netbook. I heard its only limited to 2gb of ram. But i'm not too sure. So do i buy the 4gb of ram and put it in my net book and then upgrade my windows 7? or do i upgrade then put the 4gb of ram in? Please help me

    ReplyDelete
  26. @Quiggity
    The limit of 2GB is a Windows 7 Starter limitation, not a hardware one; you can therefore install the 4GB and upgrade your Windows after. Note that if you use a "Windows Anytime Upgrade" to upgrade, you cannot switch to 64 bits and therefore you will be limited to ~3.25GB of usable RAM (which is still much better than 1-2GB).

  27. @Zenthar i just bought a windows 7 home premium 64 bit to upgrade to 4 gb, now how do i upgrade to 64 bits without using the dvd drive?

    ReplyDelete
  28. @Quiggity
    You will have to create a bootable USB stick from the Windows 7 DVD and use that. Otherwise you would need an external USB DVD reader.

    ReplyDelete
  29. 64bit isn`t that good for any netbook. You`ll have the entire 4gb of ram for only 500mb more ?! Yeah sure and you`ll have more services and more processes so... Uhm and yes, you don`t have support for 64bit drivers.
    I bought it for writting and some chatting at collage.

  30. I used the exact same RAM as OP but the computer screen doesn't turn on once it's installed. Whats the deal?

    1. Was the netbook exactly the same model? Same for RAM? The slightest difference in spec can change many things. RAM could also be defective.

  31. hey all, i have this model netbook and want to upgrade to 8GB memory (using Windows 8 Professional 64 bit).

    i'm guessing that this netbook should be able to read that much memory, correct?

    thanks!

    1. I don't have my Netbook with me right now, but you might want to check if PCWizard reports on the max DIMM size the MB can support. If I remember correctly, my initial investigation only mentioned this to support 4GB DIMMs, higher density modules might therefore not be supported. It might work, but I would make sure to have a plan B.

      Delete
  32. thanks for the suggestion- i checked PCWizard and looks like it supports 4GB maximum module size, although it supports 8GB maximum- plus it noted two DIMM slots, one being empty- i didn't see another memory slot anywhere- am i missing something?

    thanks again!

    1. I think there is "technically" another memory channel, but due to space constraints, Acer never added the actual connector for it (the circuits might not even be on the PCB).

      Delete
  33. thanks for that information, good to know! do you know what the maximum memory speed that this netbook supports?

    i thought that i saw this noted somewhere in PCWizard, but can't seem to find that information.

    thanks!

    1. I think it's DDR3-1333, not all modules might be compatible, since this is a netbook it seems very voltage sensible.

      Delete
  34. thanks, i also checked this page, which notes DDR3 1066 support for the CPU- am i looking at the right netbook information here?

    http://panam.acer.com/acerpanam/netbook/2011/Acer/Aspire/AspireOneAO522/AspireOneAO522sp2.shtml

    do you know where in PCWizard (or any other hardware utility) I can check for the memory support?

    thanks again!

    ReplyDelete
  35. Yes you are looking at the right info. However I can't remember if the DDR3-1333 module I used was simply downclocked to DDR3-1066 (which most DDR modules allow) or if the spec were simply very conservative (as it was the case for MAX memory); I think it simply downclocked the RAM since all doc I can find say DDR3-1066.

    For PCWizard, I think it was somewhere in the "Motherboard" section, perhaps you have to check a few subsections as well.
