[Solved] Replace main memory module on notebook

I have a Gateway MX-7120. According to their support site, my NB has 1 GB of RAM with one DDR SODIMM slot. I had installed a 1 GB SODIMM in the slot previously. I checked to see if Win7 would run using the Win7 Advisor tool from Microsoft. It reported I had 1.5GB - 512 MB integrated and 1 GB in the SODIMM slot. I contacted Gateway and they claim my NB only has 512 MB, contrary to their support site and manuals.
So, is it possible to replace the intgrated RAM on the mobo?Unfortunately, no one makes 2 GB PC2700 SODIMM that I've found.
Thank you.

According the specs at Gateway's site:

Memory
512 MB DDR (1 × 512 MB) SODIMM (PC2700)
Expandable to 1536 MB
Total: 1 DDR Slot | Available: 1 DDR Slot

Now from that, the impression is that the computer came with 512MB of RAM and there was still a DDR slot available in which you could install a 1GB module. And that sounds like what you did. So aren't they right? Your NB only "had" 512MB and you added another 1024MB?

In the manual:

Adding or replacing memory:
Your notebook uses memory modules called SO-DIMMs. The modules are available in various capacities and any module can be placed in the slot.

No, doesn't seem to be ANY 200-pin SODIMM of 2GB size.

Normally, integrated RAM means soldered into the motherboard. But it would be odd to refer to such memory as:
512 MB DDR (1 × 512 MB) SODIMM (PC2700)
In addition, no one solders RAM onto a motherboard anymore that I know of. It results in prohibitive costs (to the manufacturer) to fix when RAM fails - and it does.

I'm betting that instead, your NB has a 2nd slot, not accessible by the user, with a normal 512MB module in it. I would pursue this with Gateway support and see if they'll admit to it. Likely there's also a similar NB model with 1GB standard and upgradable to 2GBs. Then you have to decide if you want to take it apart!

The other more obvious answer is that you have a notebook, a limited upgrade device, that dates to late 2005. It's not well-suited to running Win7 - and wouldn't be much more suited to it with 2GBs of RAM rather than 1.5GBs. Why not let it rest in peace and enjoy its golden years running an older version of Windows? Is there some application that you NEED Win7 for?

1.5GB is the max the machine will handle. 512 is "non-removable" and the open slot you've already maxed with a 1gb chip.
