Replacing RAM chip in a acer aspire 3000

i own an aspire 3000 which has been quite sluggish so i thought it was time for a RAM upgrade.
1. To get to the ram you will need to unscrew the 2 little screws which are located on the middle panel on the underside of the laptop.

2. Once the screws are totally unscrewed (they will stay in the panel) slide the entire panel foward to the front of the laptop as far as it will go this is normally about 2-3 millimeters.

3. Gently prise up the panel with a fingernail or flat headed screwdriver, then apply a modest bit of force to remove the entire cover. do not be scared to apply lots of force as this is the only way you will remove it.

4. Install the RAM module

5. slide the cover back on into position the same way you took it off and screw back on

I found the user manual at

Page 63 of the acer user manual listed these steps for changing the memory:

"1 Turn off the computer, unplug the AC adaptor (if connected) and remove the battery pack. Then turn the computer over to access its base.
2 Remove the screws from the memory cover; then lift up and remove the memory cover.
3 (a) Insert the memory module diagonally into the slot, then (b) gently press it down until it clicks into place.
4 Replace the memory cover and secure it with the screw.
5 Reinstall the battery pack, and reconnect the AC adaptor.
6 Turn on the computer.

The computer automatically detects and reconfigures the total memory"
