POWER EXEC WITH SUSPEND AND PARALLEL PRINTERS
|
||
|
|
|
||
|
|
|
||
|
|
The Power Exec may be unable to recognize the mouse when resuming from
|
||
|
|
Suspend if a printer attached to the parallel port is powered on. When
|
||
|
|
placing a Premium Exec or Power Exec system into suspend, make sure that the
|
||
|
|
printer that is hooked up to the parallel port is not powered up before
|
||
|
|
suspending your system.
|
||
|
|
|
||
|
|
The printer has its own power supply which is still connected to your
|
||
|
|
portable computer. This power supply leaks current into the peripheral
|
||
|
|
control area of the suspended system. This does not pose any serious
|
||
|
|
problems to the electronics inside the computer, but when the computer
|
||
|
|
resumes from suspend, the peripheral controller will not be able to
|
||
|
|
distinguish a PS/2 mouse or a SmartPoint trackball until any current
|
||
|
|
applications are reset.
