Check the Acer web site and make sure U are putting in the correct type of DDR2 ram. Even though they are called DDR2, there are different types, i.e. 5300, 5600, etc.

SOURCE: how to install memory upgrade
One othe slots for memory is under your laptop, and the other one is under you keybord. The one under you can reach by loosing the screws to the hatch. The one under your keyboard you can reach by remove your keyboard, the screws to remove the keyboard is behinde your laptop, they are on the hinge.
Be VYRY VERY carefull when you removing the keyboard, its al plastic and very very easy to break. Loose the screws on the both hinge, pull the keyboard backwards and up.
As i sayed before, do it very very carefull.
Good luck to you

Sorry- I have to disagree, One screw at the back releases the lid. Inside, the dvd/hdd sub-chassis has one screw holding it to a brass post on the mobo. Undo that, then lift the chassis slightly with it's plastic strap handle, so you can detach the two connectors from the SATA drive, and the ribbon cable to the DVD (careful you don't bust the latch).
Then the whole lump simply lifts out- and you can see the 2 memory cards. The one I've just looked at appears to have 2 x 512mb simms- so you could replace these with 2 x 1024mb DDR2 SDRAM simms, to give 2GB of ram, which is what Acer say is maximum.
Cheers- AL (Luton)

This is because your computer is sharing the physical memory with the graphics memory so it will actually subtract the amount of the shared memory from the physical memory in the computer giving you the 780 that you see because the computer reserves a portion of that to use for your graphics.
