my lappy has some terrible fps... and it goes down to 0 when 200/200 army engage each other. a lot of games are lost just like that, without fighting.
i tried everything, put battery on high performance, set all graphic setting to low, editted that little notepad file and set every graphic to minimum. now my starcraft 2 looks just like warcraft 3.
even my warcraft 3 doesnt have this screen freeze problem.
i have 2 GB RAM and ATI Mobility Radeon HP5430. Screen resolution of 1366X 768. by right starcraft 2 shudnt be a problem for me right? but why when i play the screen keeps on going freeze and my fps drops to 0...?
what shud i do now?

the only way i can play now is cheese...
There are a lot of factors affecting performance. Here is what I gather from your posts:
- i3 380M @ 2.53GHz
- Mobility Radeon HD5430
- 10mbps internet
- 2GB RAM
The bottleneck of performance is your RAM. You ONLY have 2GB.
Like you said, SC2's minimum system requirements shows only 1GB of ram. But, for any of today's games, 2GB is just not enough, especially with Windows 7 hogging up most of this.
If you have around RM140 to spare, I suggest you upgrade your RAM to 8GB. Corsair sells 4GB RAM modules at RM70 each. I am pretty sure that you have 2 RAM slots, and since you have an i3, your chipset will allow up to 8GB RAM installed.
I recently reformatted my workmate's Compaq CQ42. It's 3 years old and had 2GB RAM built in. He had the same complaints as you do while playing SC2 and D3. I suggested, nay, advised him to upgrade his RAM. He did and he's happily back in his man-cave playing his games.
Trust me. RAM is the cheapest upgrade you can get.
Oh yeah, you may also want to clean your laptop's exhaust vents. A clear air pathway will also help in performance.
