>Release:        NetBSD/hpcmips 4.0.1
>Organization:
None
>Environment:
NEC MobilePro 750C
>Description:
Backlight does not turn off and screen is not blanked when trying to sleep, suspend or even close the lid on the NEC MobilePro 750C.

In addition, sleep and suspend do not work correctly at all. Attempting to sleep will typically do nothing, while attempting to suspend will typically lock the machine up, leaving it unresponsive to anything but a Ctrl+Alt+Esc to enter the debugger. It may take a few tries before it will react properly.

Additionally, leaving the device in this psuedo-suspend mode for an extended period, or even leaving the device alone for too long will cause it to lock up hard and respond to nothing, it shares this particular behavior with the NEC MobilePro 880.
