Re: New Members - please post your introductions here

Hi,
I'm interesting in the hardware of notebooks.
I like to search and eventualy repair the hardware fault, but i'm a newby.
I also need to learn reading the system diagrams. But i try to do my best. I'ts still a hobby. I'm making a DIY reflow station. Here i get the problem to make a automatic system. I got temperature switched heating plate and Infra red top heating. But it's still manualy.
So i hope to find some help here...
I'm very happy that i found this forum.

Greetings...
