Question about HP Compaq Business d530 PC Desktop
Why not say what you are up to? (end goal)
what RS232 device is it,??? be nice to know that one key fact , no?
btw XP does not handle COM ports well.
In fact you can not run 2 com ports at same time, or it conflicts.
so turn them all off but one. (id go COM1)
ever seen BIOS before, they can be shut all off or 1 or 2 to 4 on
depends on the exact MOBO that.
most pc now have no such ports, they are gone.
today we use USB with the RS230 prolific dongul, adaptor
to get vitural com ports.
and never RUN XP, its horrid OS
I have vast experience with RS232 (IBM COM ports)
and 485 and IEEE488. running factories with it before Ethernet cam out and TCP-IP .
if you told me end goal I would have gave you all;choices but you didnt.
running an old RS232 printer?
running car software with a Rs232, ECU interface to monitor engines? (i have 2 that work)
a serial terminal ? using hyperterm or Procomm?
some other odd relic?
no more facts.
some mobos have 1 com port but 3 more not wired.
others have 2, and 1 wired
some 2 wired
some have non but the chip there but unwired
you need to know that before using that DB9 JACK
for sure. and varies by actual model and SUB model.
D530-xxxxx what is xxxxx
its SFF , right? small form factor PC
sold with OS2 or windows and windows 98 through vista
guess at 2004 year, PC.
ok read the product page on this pc
it has Serial - Optional via PCI card
so is your com port HP or other brands,(vast there are)
why not ditch the it and buy this.
PC has 6 USB ports.
we use this to make a RS232 port, but
if going 100 meters, it will fail. you never once said what.
ive run RS232 to max + distances with real 12vdc +- cards
and low capacitance cables $$
the Prolific chips are not 12v, but 5v and only run short distances.
one of many sold
watch out for counterfeit chips, some top brand software
finds (bogus) Prolific chips and shuts down.
rare but needs knowing.
new egg has them and are legit.
it creates a virtual com port, and just works great
used it on my of my old (unstated ) hardware.
next time post what COm port car is there?
most cards have a secret hot key, to its OWN BIOS.
like all SCSI cards have, or SAS or ? the like
the card has a book and this is covered.
need to know what card it is first.
if you see errors above, that is because i have not your service tag data or you mobo HP part numbers.

SOURCE: re: Hi :) plese help
try to refer this problem to your manufacturer/ store owner of your laptop because most probably its either your memory(RAM) or your video card needs to be reset.it may have loose their connections.
because in the desktop PC's, these are the common problems especially upon booting up your computer.

You are missing the front headphone / microphone connector that plugs into the motherboard. Or a way to jump this to close the headphones so the sound will come out the back.
