    • Gently lift the I/O board up from the right side of the case.

      • The I/O board is attached to the motherboard by a short cable.

    I took apart an SSD variant. At this step, there were two screws holding the SSD down, but the SSD did not come out with the main and daughter boards. Detaching the I/O cable freed the mainboard to come out with or without the daughterboard.

    there are 2 silver screws that need to be removed in this step your picture shows them still installed (one is located neer audio plug, the other is located neer keyboard plug) in step 27 (next step) they have been removed without mention

    I have added 1 gb of memory to my ZG5 thanks to this helpful guide. Total cost, including a spudger and a new mini screwdriver, to tackle the 00 Philips, GBP 17.57

    I fear I haven't put the trackpad connector back properly, but device works great with a wireless mouse. Very many thanks.

Thanks a lot!!

It worked for me!

Marc Teclas Garcia - Responder

This guide lacks important information and technical accuracy.

The ZG5 can handle a maximum of 1.5GiB RAM, and realistically, can handle only an extra 512MiB RAM on top of the 512MiB fixed RAM, because of variations in the actual amount of RAM on the card you install.

I followed the entire guide, I have no more available RAM, and the tracker pad no longer works.

Thanks a bunch! I now have a netbook that is no longer a functioning netbook.

Please remove this guide until it addresses these important issues.

You are unfair to the author. This guide worked absolutely fine, and the guide has nothing to do with how much capacity your Acer Aspire One has, it has to do with how to exchange the RAM...

IF you want to fix things like highly compressed technology / like a mini laptop / yourself, you need to be sensitive. The way I have seen 9 out of 10 persons, they do not have that sensitivity. It is not a fault on you, and does not make you wrong. But you must be conscious about if you do not have the necessary sensitivity to do this work.

IFF your pad is not working, then try to do the same operation once more and be aware of how the mini laptop is to be handled at the various parts. I would guess that we are missing a wire in your laptop or something like that.

And - if you want it put in another way - since you couldn\t master doing it - then the money you saved on that RAM exchange - you can now spend them on fixing that small pad problem - with a professional.

I am blaming you for blaming the author.

@Stone Forest - Come on, I followed this guide to upgrade my son's and my wife's friend's netbooks without problems at all. All you have to do is make sure you do the work on a static-free surface, wear your anti-shock/static wristband (do this ANY time you handle computer equipment!) and follow the steps. Voila!

I tried to install Kingston KVR667D2SO/2GB. the result is that doesn't work. did anybody try to install the 1GB?

el capitan - Responder

I installed a Crucial 1.0 GB and it works great-making total RAM 1.5. I had to play with the track pad cable to get it right===a couple firm seatings finally got it in the correct position.

wrgnc - Responder

Very good guide!

I upgraded up to 1,5Mb my netbook.

It works fine.

Luigi Cuccu - Responder

woked for me, using crucial CT1286AC800 M8FJ18

(1gb 200pin DDR2 Sodimm 128Mx64)

step 8, with no cell radio this is not needed (as mentioned)

step 24, with SSD no need to remove daughter board, can pivot MB on cable and insert memory (as mentioned)

step 25, hinge bracket, dont need to completely remove screws, the hinge has a part that is above the MB, can just losen and slide MD down

when reinserting the cables with the locking arms, SSD/keyboard/trackpad, make sure fully home, can be quite hard to tell due to the still/short cables. (experience from other stuff.)

I used this guide once to replace the motherboard then again to upgrade the ram. Now I have a serviceable portable starting from a completely useless paperweight. Thanks a bunch!

Anthony Kurilla - Responder

Worked in first shot, and have given new life to my outdated netbook.

Thanks a lot!!

Thank you very much for this guide. I was able to successfully replace the removable 512mb ram with a 1GB with virtually no difficulties or setbacks.

Has anyone replaced the 8 NAND flash memory on the Acer Aspire One A0A 111? Is it soldered in? Will the board support the 16 Gb flash memory ?

gtdiller - Responder

anyone ever tried to put in a 2gb-ram AND switch OFF the internal 500mb <- should be possible by opening a single line called "chip enable" or "chip select" greez

biopilz - Responder

would like to try it myself...

got a suitable 2gb-card laying-around...

all i need:

did not yet find a PIN-LAYOUT of the board to identify the RIGHT line to open on the pcb...

(maybe it wont work as these pcbs are multi-layer and it could well be that the line coming from the controller-chip is in the depth only...)

biopilz - Responder

...that the line coming from the controller-chip is in the depth only...

-then we could still try to desolder just the right cs / ce - pin on each memory-chip!

biopilz - Responder

for the record

am waiting for further feedback...

to get to the right position it needs complete disassembly...

-dislike to procede opening the ebook to avoid unneccessary damage to the joints etc

especially theses delicate foil-connectors only have a limited number of in/out-cycles...

are others out there less hesitating? -yet am quite convinced its the way to go!

biopilz - Responder

Worked like a charm, thank you so much!!

Marco Fontani - Responder

This is way too much work to upgrade ram, But I'll give it a go.

Murray Ferguson - Responder

I know this may seem logical 1 + .5 = 1.5 gig but My system reads 1 gig not 1.5 gig but speccy says 1 slot of 2 used.

It says it has as a single 1 gig stick.

So does that mean I have a 512 stick installed ??

related but not, does vram setting effect stability of the system?

Ian D. Mah - Responder

No. I think, You have a so called high density ram module put inside. But You need a low density module. You are on the right side if the modul (1G) has 8 chips on bouth sides of the modul. Otherwise You must ask the dealer if this module is a low density one. Your module seems to be recocnised to half the capacity. You have to change it if You wish to have 1,5 G on Your netbook.
