Not to revive this old topic, I got a PM of someone who helped in this topic, who wanted an answer. Its only fair I do so;
Sadly this issue did not get resolved; As I said before, the issue probably is related to the battery and software related, when booting on battery. I can't easily reproduce and I try to boot on cable mostly always, cause my battery only holds 10-15 min anymore. I generally update windows (7). And ignored the support to upgrade my bios, I don't feel secure enough to do and generically I prefer a crazy background lid above a dead laptop. Note this issue is even there when plugged in after battery-boot.
As a programmer and a crazy scientific this is bugging me to the extreme, but I can't risk shooting myself in the foot, since I don't have a backup laptop.
