|The PNY configurator:|
It lists NO Advent laptop or netbook models.
I know from previous searching

The only 1gb part numbers they list are the latter .
If you don't have that, or one of those, part number(s), then there's no guarantee it will work properly in your computer.
The part number is almost always printed right on the label on the module.
If you don't have that (those) part number(s), if you haven't already damaged it , you can return the ram, but if you bought online, you will have to pay for the shipping yourself, and you will probably only be credited with it's cost after it has been tested and found to be not damaged.
There may also be a fee deducted for testing, or a re-stocking fee that is deducted, whether you return it locally, or online .
I know from previous experience the PNY configurator sometimes lists modules a computer doesn't actually support.
In this case, I have found no info elsewhere that your model supports 2gb modules.
