how is it possible that many ppl try mining on notebooks? you cannot get a good cooler on it. am i wrong or its a fast way of burning your board?

My GPU running at full tilt in my laptop (radeon 6770m) doesn't significantly heat up the laptop. And this is an HP we are talking about (they have a terrible corner cooling design).

My CPU, on the other hand, running at full tilt would kill my laptop through overheating (i7 quad, 90+*C and throttling when H264 encoding).

My board will not burn if I just run the GPU. Even overclocked to 850MHz, pulling 110MH/s

My actual concern is the longevity of the battery. When I mine for more than an hour or two, I take the battery out.

So you can't generalize all laptops but I recommend making sure the temps are reasonable (GPU-z and core temp - check both as most heatsinks are combined GPU+CPU) and always removing the battery if you intend to mine for more than a little bit.

Just a comparision of my setup:

AMD/ATI XFX Radeon HD5870 vs. AMD Phenom II X4 955 BE
GPU: ~370 mhash/s vs. CPU: ~2.2 mhash/s

Conclusion: Mining on a CPU is useless.

Then you are using a terribly inefficient and old CPU mining program. I get 3.9MH/s per core of my non-overclocked 1090t.

(I used pooler CPUminer 2.2.2 64-bit.)
