Hi,
I have some queries about Windows OS on Desktop machine
and noteboook machine.I am using an external harware which
will be plugged in the serial port.The hardware works fine
when it was plugged in the desktop machine but somehow
it's not working when connected with the notebook, Both
system uses Windows XP OS.I have tried this with couple
of desktop and notebook machines and still getting the
same problem.
By using a serial port analyzer i found out that the power
level of the serial port changes when the Windows OS
starts to be loaded in the notebook system.My hardware
actually works fine(receiveing the correct signals)when
Windows OS was not loaded in the system(during start-up).
>From this observence I have a few questions to ask:
1. Does this means that the start-up power level differs
with the power level after the Windows started to operate
in notebooks?
2. Does this voltage actually controlled by the notebooks
bios or the Windows OS?
3. Is there a posibility for the Windows OS operates
differently with Desktop hardwares and notebooks Hardwares)
in it's power management?(if yes, anyway to disable this?)
(I have already changed the Start->control panel->power
option to desktop in WIndows OS of the notebook but it's
no use)
4. Could it be any other reason besides the power?
5. Are there any other serial port differences between
desktop and notebook computers that I need to consider as
well?
6.Both the systems that we are using are from dell, i have
already consulted dell support, according to them, there
are no differences in their notebook start-up power level
and when the OS was loaded.They also suggested that it
could be the driver problem.
Thanks in advance
