i can't teach connector damage 101 here

nor can he show his damage VGA connectors.

[savvy2]

turn off

sleep

and

hibernate

buy a new cable.

[savvy2]

i have posted all possible causes.

hope it helps you in some way.

we cant do the tests for you , nor see results nor use logic here,

only you or your service agent can, (omg geek squad?)

but do know , PNP does not exist on that 2002 monitor.

sorry, that began in 2004 late.

sorry,  evolution happened.  and the fix is easy turn off sleep. (cable not damaged)

the driver update suggested by the technicial who first responded to my question - i can't figure out how to do that.  I can't find a place on my computer where i can update the driver to the display.  I can find a display setting but the only option is to disconnect the display.  Neither can i find the name of the technicial who suggested i do that. 

[furry81]

Dvortex.  Thank you so much.  I couldn't follow your directions.  I couldn't find out how to update the driver for the display.  I still want to try that. 

[savvy2]

the instuctions are on the HP.com page for loading drivers.

you download it.

then run it,

its a file called SP12345.exe  (made up numbers here,  but format is like this)

there is one for every chip set in the PC. (must  match your exact PC )

but there are rules to use them.,

first off is to match the drivers to the OS  you are running, w8,1 you said. so tell HP that is what you have first. there.

and be on the correct page for your  exact PC. and get all drivers there,best to do that, so you have them all and for when they go byebye after 10 years supports ends,  yes, back up your own drivers. now, to a folder say  C:/HP-drivers/

use the full model name,  p12345.exe.  (it's not a virus off HP.com so is SAFE)

then down load them and run them if  some fails that means its for other chips missing in YOUR PC. 

Facts to know: fixing all PC's made. (hardware facts)

The chips that love to be different are (VGA, (video) and Networking. (and even faster processors) and more....

end drivers 101, there is more but ill stop HERE.

More facts:

btw this pc was never designed to work with any 2002 monitors,  (pre PNP , and non startard sleep logic inside it)

learn that even one PC, one model number can have different VGA chips,  and was changed at a certain production run.

on or after an exact serial number (do not post SN here)  but that is how PCs are made in RUNS, and can have changes

based on chips available or upgrades in a run, (yes, I worked in factories for years) (as a tech)

This monitor does have sleep mode but uses a very old standard (protocol) not used today, (yes buy a new monitor if you want sleep or hibernate to work right, most folks dont care, just want to use the PC and not be bothered with Energy star malarkey)

yes, moving the mouse took it out of sleep. but the sleep mode is  failing,  it can fail even with new drivers.

after all the 2002 LCD is not PNP, or Display data channel,  sleep certified.

that means turn it off.

The LCD has its own hidden internal sleep mode too..... (not seen today but yes in 2002)

millions like you have this problem,  they never knew windows, defaults to ENERGY STAR SLEEP IS ON mode. turn it off.

 the link to your free manual on the 1517 monitor  below. (no PnP and no modern sleep modes worked)

so to get around this gross short comming the put a sleep timer INSIDE  THE LCD, here is that proof.

Operation

Reference Guide

*Sleep Timer enables you to set a time for the monitor to power

on and power off at the same time every day. It eliminates the

need to turn off the monitor at the end of the day and conserves

energy. To set this mode, refer to the Sleep Timer in the on-screen

display. Note that the time is displayed in a 24 hour clock format.

For example, 1:15 p.m. displays as 13 hours 15 minutes

see those bold words, ITS IN THE OSD menus

When the monitor is in its normal operating mode, the monitor

utilizes less than 45 watts of power and the Power LED is green.

The monitor also supports a reduced power state. The reduced

power state will be entered into if the monitor detects the absence

of either the horizontal sync signal and/or the vertical sync signal.

Upon detecting the absence of these signals, the monitor screen is

blanked, the backlight is turned off, and the Power LED is turned

amber. When the monitor is in the reduced power state, the

monitor will utilize less than 5 watts of power. There is a brief

warm up period before the monitor will return to its normal

operating mode.

Refer to your computer manual for instructions on setting energy

saver features (sometimes called power management features).

page 10 is more scary,  read this and the bold words

The Sleep Timer mode is an energy-saving feature that enables

you to set a time for the monitor to power on and off at the same

time every day. This also extends the life of the backlight bulbs in

the monitor. The Sleep Timer has five settings:

Set Current Time

Set Sleep Time

Set On Time

Timer: On/Off

Sleep Now

To set the timer:

1. Press the Select button on the monitor front panel to display

the Advanced Menu.

2. Scroll down and highlight Management.

3. Press the Select button to select Management.

4. Scroll down and highlight and select Sleep Timer > Set

Current Time.

✎

You must set the current local time before you reset the time for

Sleep Time or On Time. Note that the time is displayed in a 24

hour clock format. For example, 1:15 p.m. displays as 13 hours

15 minutes.

5. Press the Select button once to enter the adjustment mode for

hours

the manual is free to read.

if the cable is bad or connector pins fail on this monitor

if the 2 sync lines fail  it will go blank.

here is the PROOF OF THAT.

 This really is a VESA standard back then,.

The monitor also supports a reduced power state. The reduced

power state will be entered into if the monitor detects the absence

of either the horizontal sync signal and/or the vertical sync signal.

Upon detecting the absence of these signals, the monitor screen is

blanked, the backlight is turned off, and the Power LED is turned

amber. (got AMBER?)

• lets now make a full list.  now that i read your whole monitor book.
• PC is in sleep mode monitor power lamp goes amber. (did it?)  The LCD menu always works, does it? LCD select button.
• PC sleep mode  can be turned off, why not do that?  Control panel , power settings, do so now. and win.
• PC sleep mode can fail to recover from sleep (classis failure world wide) it needs the correct driver, but might not like 2002 non compliant monitors, like yoursl.  but sure put in a fresh driver, but wait, you reloaded HP OS? already.
• the Cable is bad. VGA. buy one try that.
• the Cable has 4 connectors if any is bad, it will fail. and for sure  if the 2 sync lines go dead, it will fail. for sleep
• the 1517 monitor , has  hidden inside the monitor sleep feature and time clock that can be enabled or stuck on,  is it?
• Compaq put this feature inside this very old monitor to make it work with computers that cant handle sleep modes correctly as vast numbers did then and still do today, even yours.

long ago, i remember and old monitor that the OSD did not work if the cable was bad. (or unplugged)

so i test for that, i turn it on and see if the OSD works. now. no pc , no power to pc. no cable.

modern LCD never do that, the  OSD always works (the got smarter) and even shows, no signal. if video dies. (3 wires)

walmart as a $75  screen btw.

and works on all modern PCs

it comes with free cable too... that works.

they sell VGA cables too.  cheap. $3.28 (Goodwill has em for  $1 used,  shocking no?)

i cant help you with desk sizes, only you can work that out....  (take a saw to it?)

Sir, i can see that you are knowledgeable and savvy on this matter.  But you don't pay attention.  I did go into control panel and put everything on never sleep.  And i didn't forget to fiddle with the monitor menu buttons - i didn't know enough and what i forgot was that they were there.  

So where are we now - are we trying to decide whether it's the monitor or the cable?  I'm thinking of getting a new monitor.  I've been looking at them and not sure what i should choose.  I do have a space limit.  16.5 top to bottom and 19.5 side to side and would like a little give on each side.  But then there's lcd and loc and other choices.  I'm not sure but what the connection - cable to tower - is bad and not the cable itself.  Cause the screw female part in the tower- one of them turns with the screw and it's hard to make a good solid connection.  so i see this as the trouble point.  the screws tighten.  they are tight and look secure right now.  So if i do get a new monitor i should get a different kind of attachment plug.  The tower does have another type.  This stuff confuses me.  

I'm trying to follow your directions.  Cause i like you.  That other guy Dvortex, i haven't heard from him since he suggested i update the driver and i messed up.  I'd like to try it again.  Maybe i'm not paying attention.  Senior moments abound.  

My phone seems to be okay now.  I charged up an other handset.  Same batteries so it wasn't the batteries.  I'm just afraid of being without a neans of communication.  But i'm still hesitant to turn off the computer.  Should I?  

I trust your judgement.

hello Dorine

try to know, that i can see you do the tests. (or the order done or its complete ness)

to fix any machine or electronics, tests are done and in the correct order. (simple to complex diagnosis is possible)

The first law here is "is it harware or software"  since the first computer, even Alan Turings machine. !!!

Do know too that some PC just don't like some old monitors.   1982 to 2017 , 35 years of evolution and sadly incompatibilities exist. Your lacks PnP features, and uses old sleep LOGIC, (facts)

that newer connector on your PC is called a DVI video cable, the old one is VGA both have screw downs (x2)

and both must get tight,  just finger tight not with pliers. yes jack nuts there love to fall off, go loose or are missing, LOOKING WORKS only here, I can't,

lacking a scope?  (yes I have one) and other tools I have,  breakout boxes, meters,  and such...

lacking  proper tools we:?

we are left with what?,  substitution methods and like you did, turned off sleep in the control panel.

try to know that some custmers want the sleep to work right, so posters here will tell you how, its not easy, loading drivers.

it's tedious.  for sure.  I have done this since 1982, (even before, that, on other Micro's and on DEC systems. so is old hat to me) back in the old days we had to change jumper straps and DIP switches to make all this work.

today it is the magic of PnP, plug and Pray. err play.

the driver being wrong, will infact kill sleep or the more complex and flaky,  hibernate.

we'd prove this by testing that old 2002 monitor on another system, but many  PC now have no relic VGA ports.

so that makes this hard for you,  lucky  you ,you have both ports, VGA and DVI but not on the monitor, its VGA only.

VGA is mostly dead now.  (sure exceptions) a new monitor just plugs in the DVI and works.

works better too.

so you could test that old VGA on any friend with an old laptop, and that cute 15pin VGA jack on the rear.

push the LT function key for external VGA jack usage and bingo you can test that monitor all day.

that is what most folks do,  lacking 2 PC in the home.  go to other PC, and test your PARTS.

that includes the VGA quesstionable  cable.

if the cable is bad, if those 2 sync pins are bad, or the wires broken, then that cable fails on an other PC.

The monitor does go black if either wire is dead. (by design)

we can not see your cable, nor its damage on the pins nor inside that cable end shell connector, it has wires inside that terminate on pins and must not have DAMAGE there, it's just  $3 cable why not just buy one and scratch off 1 in 3 possibles.? (4 counting software munged)

lets say you tested the monitor and cable and the monitor internal sleep, yes, it has one, inside it all by itself.

a COMPAQ magic feature, must be turned OFF or all this fails. (its  clock timer there "INSIDE IT")

you now have the manual for your compaq so the steps to do that is  clearly there..

Monitor ok ,cable ok. puts us at....?

we now are at PC tests.  

sleep is off. ok,  you said so.

hibernate is off.

wake on events is all on,, or the mouse and keyboard wake up's will be DEAD. (this is default so should work)

correct driver loaded.  its not hard but is  tedious and takes skills, all PC shops have these skills.

it can be a  bad VGA card, or its connected damage, it can fail inside the card, the pins can crack there. and fail.

Many do that, and fixed them all. in 50 year on the job.

The card on most PC can be replaced,  if the VGA is wired to the mother board directly then we abandone it

and put in a new CARD in the PCI slot there.  not the VGA card is new. and works

and guess what it comes with its own driver, 

here is one other diagnostic tool, i have vast ways , endless... really but basics here.

We get a LINUX , boot CD, DVD or USB boot stick, with Linux or WINDOWS 8 or 10, PE, live boot.

wee boot it and test your monitor,  and see that it works prefect.

that tells you  what. that ALL HARDWARE IS OK and its only a silly software problem

all techs have this disk (today a usb stick) and we see, ahhh,  windows on this PC is messed up.  because test disk works.

windows messed up.?

so reload it.  (f11 magic key documented on HP. fully)

turn off sleep again. (by USA laws its on,  to make earth Green again, )

when i said reload windows, that means , with a HP disk, or HP F11 restore key actions

it does not mean using any media,  from microsoft, did you use that?  and wreck your HP software ?

I only have questions,

[savvy2]

there are lots of trouble points

it's a powerful computer not a toaster

mile  of wire and connectors to fail.

5million transistors

3 million registry bits to fail

and 200,000 windows bloat files to fail. (and sure the 5 drivers needed for video and network)

virus/malware infections, endless. some prevent, loading DRIVERS , omg, it really is true.

that is  what I see...

If space is low get a small notbook? 

or  larger Cell phone./? many folks do this now and have no PC , no laptop no notebooks at all,  zero.

buy a new display at walmart for $138 and use DVI,  this cures bad monitor ,bad cable and cures bad PC VGA jack.

but it wont fit. desk

so leaving what?   new desk, or buy a very old, monitor, 15"  and find out most are now DEAD. this old.

most have the burned out back light. that small that old due to CCFL blacklamp horrors. of the day.

cured now with LED.  

Id go LED and make it fit.  and now has sharp looking blue/white brillances.  to boot.
