6930p: un2400 wwan only works when battery inserted?

Hi,
I am using a un2400 wwan UMTS modem on my HP 6930p (WinXP, SP3) and noticed that it is automatically deactivated when the battery isn't inserted into the laptop (PIN Code is also deactivated on the SIM card). Once the battery is installed, it works without any problems.

Can anyone confirm this being a normal issue with this modem? Thx!

(the Huawei EM770 modem on my eee 1000HG works with or without an inserted battery but it also doesn't require the firmware to be loaded first, so maybe these two can't be compared..)

 

I'd say that's normal, by design (the carriers have required it):

Wow - thx! - this exactly answers my question.

Only remaining question is if it is different on Vista (as they only mention WinXP pro).
