QNX4.25G Hangs when the Power Source switch

QNX4.25G mainly hang when the electric power cource of Fujitsu NSeries
notebook switch from AC Adapter to inside battery or from battery to
AC Adapter back. But some time it continue to work properly in fiew seconds.

How can I set electric power source switching stability for QNX4 OS on
notebook?

Thank you.

Does the BIOS have any way to turn off power management functionality?

I would guess it is trying to callout/notify a windows OS about power
state changes, or it is actually changing the power state of some
devices, and that this is greatly confusion poor QNX. I don’t think
there is anything you can do on the QNX side – but if you can disable
it on the BIOS side, you might be ok. (But, you will not get good
battery life while QNX is running.)
