|To find listings of ram modules that will work in your model (are 100% compatible with it) for sure, go to a ram manufacturer's or ram distributor's web site that has a ram configurator or similar that allows you to use your computer's make and model to search for ram modules .|
E.g. The Crucial web site
Once you find which ram module part numbers are compatible with your model, you can search on the web using that and buy them from anywhere you like, or local places may have the same part numbers.
You MUST unplug the AC adapter AND remove the main battery BEFORE you unplug or plug in ram modules, or unplug or plug in anything inside the computer's case !
"Also is there any parts from the acer laptop i can use to boost the toshiba, like prosessor or somthing."
If the ram in the Acer laptop is brand name ram, you could compare the part number(s) of it to that(those) ram found for the Toshiba model on the ram brand name's web site.
If the ram for both laptops is the same type - e.g. DDR or DDR2 - you could try the ram from the Acer in the Toshiba to see if it works properly - that won't do any harm even if it doesn't, BUT in the worst cases of incompatibilty, your computer will NOT boot at all when incompatible ram is installed.
As far as the cpu is concerned, brand name system builders web sites provide very little info about which cpus can be installed in the mboard of the laptop - it's not likely you can use the cpu from the Acer laptop in the Toshiba laptop.
Also, in some cases the cpu is soldered into the mboard on a laptop, rather than being installed in a socket, so it's not removable.
