Seriously Low FPS Rate, Any ideas?

[vGhost]

Ok I'm getting a really low FPS rate on Tekkit Classic on my laptop, sorry if I'm posting on the wrong thing I'm new, and I've tried alot of things. Here are the things I know how to provide about my laptop:

Dell Inspiron 510m

1GB Memory (RAM?)

32GB Hard Drive

Intel Pentium M, 1.5GHz

If there any other spec needed let know. I know this is a really bad spec but it was cheap, I'm saving up to build my own one. I always play on minimum settings and have tried alot of stuff, but has anyone got any suggestions. Preferably not just: Get a now computer. Thanks.
