a brand new HP 360 comes with no manual $1000 in a box.
that is because its at HP for free , you are not at HP but at fixya.
why be here? we are NOT HP.
the manuals are all there, one model might have like 30 manuals.
depends on what you are doing, they even covery up to 8 windows versions used, not in 1 manual but 8. (or 4)
so KBL: are those external speakers? you never said that.
what is your service tag full model number it is not 2500
i get no hits at REAL HP for that number.
ZE 5000 NX9010 Series???? how can it be both #?????
hp has like 10,000 models of PC for 35 years
we can NOT GUESS them ever here, the service tag must be presented by you or all answers will be wrong.
the speaker jacks on PC can be 2 channel, 3.1. 5.1, 7.1 and up.
we have no idea what you have there, at all. period
I get 1 hit, NX9010 at HP.
so if that is the model prefix (missing P/n on tag shown)
do know this that one model like this can have 5 different motherboards used, even for sound.
some have low end sound chips other higher end. more jacks.
seen. no photos for your jacks by you pressented.
so connect the speakers to the green jack.
speakers out. 2 channels.
this Laptop NX9010 came with zero external speakers
so you previous owner added them.
no JBL part numbers stated of the 1000s made.
the nx9010 front most 3.5mm phone jack is green
and is for head phones,
to use speakers they must be amlified speaker
you buy those and it has 2 speakers, a cross jumper from one to the other, and from the main speaker (has volume knob)
there is one cable from it to the PC green jack 3.5mm
then the main speaker needs its power pack connected with power on, this turns on the magic Amplifier inside.
this makes the speaker work on any pace made from 1990s to now.today.
off the green jack only.
then set the speaker to 1/2 volume
and then at the PC raise volume till happy.
that is it for 2 channel technology audio.
some PC have more fancy setup.
but here is your book free to read for 14 years
most of this PC are dead now, the CFFL lamps long ago burned out and screen dead forever.
read page 50.
all the other books this pC are here. every one.
