According to the specs of this laptop is 1GB Max. So you can't use a 2GB. Also it states that there is only 1 slot for memory. Which means you can not add another stick of memory, you can only add 1 stick to it.
To add you turn the notebook upside down and start to unscrew. look for the 'memory' section. However doing this would be pointless.
If your experiencing slow processing, try to remove programs that you don't use anymore. Make sure some programs don't 'start-up' while your computer is loading. WARNING*** you are responsible for your own actions
Go to: START > type msconfig > click the 'Startup' tab > Check for unused programs running (example: msn messenger, Uncheck the box; if you don't know that program then don't uncheck it) After your done, click OK and Restart your notebook.
For future information:
- If you are going to add memory, make sure it is the same type (example: pc5300 on old chip and new chip) otherwise you will burn out the memory.
- Always check online for your laptop/notebook specs before doing adjustments, otherwise you risk chances of burning out the notebook and or devices your trying to add into it.
- If you can afford it, buy a new notebook/laptop.
Good luck, and rate my advice.
