Only with Compaq NX9005 laptop. Wireless card will not
work on battery power - shows in device manager as unable
to start (code 10). Works fine on AC power. I've heard
a rumour that this model laptop may not have been built
according to Microsoft's ACPI standards - as I understand
it the card needs a 5v power supply and when running off
battery, could it be possible that the card is only
receiving 3v and not initialising as a result. HP so far
have refused to help numerous people that have complained
about this. It has to be a power related problem as the
card works fine on AC and works fine in other laptops.
Any advice anyone?

It caused problems here as well (no-name laptop). The card never
worked well with the Power Management features of Windows XP
(blue-screen error with AIRPLUS.SYS). I switched to a Netgear card
which also causes problems (network sometimes is not found
automatically) when the machine returns from Standby/Hibernation.
However, this does not halt the entire Windows session and so is
somewhat acceptable for me. I have learned that most of these devices
do not work well with ACPI power management features.
 
I have a Sony Vaio notebook and I'm getting Kernal Mode exceptions in
airplus.sys, "Driver Irql not less or equal" blue screens. Windows
2000, sp4. Usually when the computer comes out of standby mode, so
that goes along with the ACPI theory. I was thinking of upgrading to
XP in the hope that it would handle sharing the IRQs better, but now I
don't think I'll bother.

I've spent many hours on the D-Link tech support phone number now and
they have offered a few workarounds ("oh, don't let your computer go
into standby mode.") I've got through to the lead of their level 2
support and he claimed that they've never heard of a problem with
their card when it comes out of standby.

I've contacted Sony as well and while friendly on the phone, they
weren't able to help either. It seems that Sony locks down the BIOS,
so you can't get the ACPI and the wireless card off of the same IRQ
(they're both sharing 9).
