I would see if you can fit any more ram in it.
Sometimes a computer will handle more ram than
the manufacturer says it will. Upgrading the cpu
in a laptop is rather tedious and probably too expensive
to make it worthwhile.
I'm using dell vostro A860 notebook
-mobile intel 965 express chipset family
-vista home 32- bit
-processor intel celeron 2.13 ghz
However, I would like to upgrade my processor to any core 2 duo but I'm not very sure about the compactibility issues. Which processors can I use? Can I use intel T5870? I need help. thanks
