Looking for a laptop...

Flexline
I just recently got VS 2005 installed on my work laptop, so I actually have a compiler to use again. The flexline hasn't been updated really at all recently, but I did find a bug in the triangle rasterization code. Since this is a software rendering system and completely separate from my DX renderer, I haven't implemented a screen shot system yet, making it hard to share what is happening. I guess that will be next on the list...

The Laptop
The power supply destroyed the charging circuit on my laptop - I can no longer charge the battery using the laptop itself. I took it all apart and have been probing the motherboard to see if I can figure out what parts are in the charging circuit, but it doesn't look promising.

*DISCLAIMER* Don't do this! *DISCLAIMER*

So I am going to try to connect power to the laptop through the battery connection, but still supply the power with a power supply. To understand how the battery configuration works, I opened up the battery case. To my dismay, there is a logic board inside that controls when voltage is allowed out of the battery, making it difficult to see which pins would need to be supplied voltage.

To see how the circuit works, I am next going to connect the battery and power it up while probing the interface pins of the laptop/battery connection. And yes, I know it is looking grim but it is more of an experiment/challenge now than anything.

I have started looking for a new laptop. Does anyone have any recommendations or recent good purchases that they would suggest?

Eep! Challenge? You might as well challenge yourself to sticking a fork in the wall socket. My my mother always said: don't play with voltage-laden batteries. :P

I'm quite happy with my Macbook Pro. It runs Vista like a scalded cat (even under virtualization), and you can get like $600-$700 off with a student developer discount (as well as betas of new OS and developer tool releases).

Any recommendations?? How about not doing that!! :P The control system you see is in place exactly to prevent abuse; if you start playing with it there is a number of bad things that can happen to the battery, or to you. [BTW on a totally unrelated note, I'm afraid of capacitors now] :)
