I am working on my neighbor's slimline HP right now. His HP was having the same problem and has an extended warranty thru HP. He sent the computer to them and was told the motherboard is bad and not repairable. They actually told him to go buy a new computer! I told him I would take a look at it for him. I could not verify if it was the on-board video because even though the board has a PCI-E slot only a half size graphics card will fit and I do not have one. I need to verify that it is not the power supply but the problem is the board uses a small form ATX connector so I had to order and adapter for $15 and I am waiting for the part. If the power supply turns out to be then I will probably install a new motherboard. The problem is there is no where to get a new motherboard for this model(was made by Asus for HP). There are only used available one's available with no warranty. When I get the part to test the power supply I will post an update to you.

    Well the part came in and I tested the board with another power supply....and the board is dead. I did find a guy on e-bay that sells them and ordered one. Here is the link.

    I tested the power supply and found the board is dead. Found on on E-bay for $83 including shipping from Hong Kong. The guy had more than 10 of these boards available.

  • muebe Sep 19, 2009

    i just installed the board and the computer is working again. It looks like this board has updated capacitors and I guess there was a problem with these boards going bad. The guy on e-bay is making a killing...he has sold 1,100 boards in the past year and has 10 of these available. And he just raised the price on this board to $93

How do i get my hp w2007 monitior out of sleep mode


no PC stated or OS.
is this VGA, DVI or HDMI?
guess VGA. and its matching cable.
there are 2 sleeps, on old monitors.
the PC sleeps the monitor by disabling the 2 sync,. wires
HORZ and VERT,
the display shows, NO SIGNAL when this happens.
2008 (your monitor is 2008 , can be)
older monitors , have built in sleep, called also power saver TIMER. (push menu button on monitor)
read page 4-5 in your free HP manual.
PDF page 31.

http://h10032.www1.hp.com/ctg/Manual/c00834092

(aobut 1/2 do not have LED back lamps this year)
also this monitor has CCFL back lamps that by now
all go: most are dead now, used every day 8 hours per day.
1: dim
2: yellow
3: dead
4: or works 1 day , minute or week then not. (random)


if the pc tests ok on newer monitor, then its not the PC
if the Monitors fails on other PC , turn off power saver inside.
if the CCFL is dead, shin a flashlight on the screen, see data.?
if yes, the CCFL lamps are DEAD. (now or soon or whenever)

Hp P6000 fans stop after 15 seconds. Hard drive light stays on. nothing on monitor


dead PC, DESKTOP PC ,as old as 2009.
the fans tells you the PSU shut off, for cause.
fans, so you saw all fans turn off or just 1. or 2 of 3.
my pc has 4 fans many have 3;
CPU fan stops ,cpu overheats , PC goes slow or dead. clean the lint off it.
GPU fan , video goes dead. if it overheats.
PSU fan is inside the PSU if it goes bad, PSU is bad.
no monitor stated, is it CRT or LCD is it 15 years old.
if the monitor is 2002 or newer the OSD screen works
even with PC turned off, press the select button see that OSD screen ? telling you the monitor is not dead in 1second flat;
i caN NOT understand why the HDD lamp glows,
if the PSU shuts off , most LEDs go dead, on my PC
the standby LED on the MOBO glows, unless you pull the PSU power cord.
your HP PC came with 9 different mobo, during its production run.
at least. so answers come harder from that reason.

here are some simple tests.
test 1
power on, hear fans run
does the DVD drive (or cd) button eject work,.?
do all fans not just 1 or 2 worK? look for all fans clean the lent out
or things will overheat,
PSU can be bench tested or in the PC case.
using a jumper wire, even the HP service manual covers that.

power on the PC (after keeping monitor on for 5 full minutes)
test 2
the Screen must say, "hit ESC key to enter HP setup" BIOS.
press the ESC key on the monitor
if no text shows up that is a dead PC< "text above missing{"
if the PC told you to hit another key do so.
The ESC key , activates the BIOS brain. this cause
all those pages to work as seen in your service manual;.
if BIOS is dead that is a bad PSU (monitor ok)
or CPU is overheated.
bad ram, take all sticks out and test 1 by 1, ask how. !
The PSU will shut down on up to 12 or more faults
but never shuts down the standby power bus. unless AC line pulled.
IF the PSU has fan as most do this is the first place I look.

no Monitor stated. (maker, CRT, LCD what?)
The monitor is not fibbing to you BTW, the PC did go dead or to sleep. seems its monitor monitor of some kind with DVI.

if the monitor works on other PCs then the monitor is not bad.
i Bet it works (old ones 2002, have a hidden deep internal sleep mode. and is not yours IM sure now) DVI IS THE ONLY CLUE THERE.
So PC is dead. this PC came with only VISTA new,
is it still VISTA?????????
HP has support on it still
here (carbon dated by me 2008, IIRC)
https://support.hp.com/us-en/drivers/selfservice/hp-pavilion-slimline-s3400-desktop-pc-series/3688715/model/3688723

this year,? get all those files and books there backed up
when HP support ends after 10 year rule, (be savvy?)


what keyboard USB or wireless keyboard mouse
use wired USB keyboards if wireless the battery is dead. easy no?

now in VISTA, go to Control panel, click power
turn off all sleep modes and all hibernate modes
the turn off screen savers, if turned on , disktop . RC right click
in display settings or personalize, turn off , need login to come out of sleep or screen saver.
try a real keyboard, that has USB cable yet? be first thing to do.
always keep a real keyboard, handy,,,
batteries fail. in all wireless devices like this (inside them)

luck you desktops have lies DIM fails. there are many.

http://www.pcdied.com/sleep-or-dim.html

one other way , and common is PC overheated.

#1 all time cause of overheat and PC shuts down.

The monitor will go into sleep mode, and when first booted up will not register anything and goes to sleep. Have tried re-booting, checking the chords, plugging and unplugging them in. To no avail it...


No pc stated just monitor. (not even desktop or laptop) stated.
no OS stated, ether.
so ill answer in wide generic ways....
all computer are a problem, since days of Mr. Allen Turning to now.
ive done 43years of them just puters.(and other big systems MIL)
no person on earth can answer that common question
gee no pc stated,! nor can we lay blame until its fixed can we. ever.

3+billions of transistors. mine here typing now.
4,800,000,000, and friends, lots of other things to fail even LCD
its not a toaster or 4 banger calculator, at all.
its COMPLEX but 1 of those 2 boxs or cable are bad. sure.
(viewed in the MACRO)

sleep? how do you know it is sleep.
the screen showed that. text said SPEEP?
is the screen totally dead. (that is not sleep if true)
is the screens OSD button dead?,
the only clue i have here is one word, REGISTER (good word just too few)
so the screen never ever shows any text or HP logo ever
booting with monitor on for 5min. power on PC, see words?
no text ever...so.

then push the monitors.
Select menu buttons on front of monitors. and the OSD pops does it , it must....!!! see image below (mine is Viewsonic, near new)

there are many simple tests here.
  • try you monitor on any other PC
  • or try you pc on any other monitor
easy no.?, just 1 or 2 tests and bam, who's bad.
called the process of elimination..
but OSD is first. no matter what,.

if the screen tests ok,, (display tests and its buttons)
then the PC is problematic, (1/2 the battle won)
the first thing to do (tell me what pC) but turn off all sleep
modes in the CONTROL PANEL + POWER SETTINGS>
do that first. if you can even get the screen to work.

A pc never boots to sleep so.....
the PC can have 2 VGA jacks on the rear.
the PC can have DVI jacks, using those are you
try them all yet?
if you test the PC and it works and the screen works the cable is bad.


omg that screen is new, its even sold now at walmart.
not cheap either, too much, kinda
this is a modern 22" screen, LED>
and do not just go bad, is the power pack there and correct?
if the OSD screen is dead, check power first.

this is the Monitors brain, it works even with the PC dead.


the button is marked menu or select. this is test1.
osd-1z31dkbg41o2owghj0fas5br-1-0.jpg on my monitor ,heck all 2004 up
it tells you SLeep mode when the PC goes to sleep mode
or shows Power saver mode. live on the screen.
screen power on first sure.

all ways to go black done here.

Why does my HP vs17 monitor screen keep going to blank black screen like it turned off but did'nt.....blue power button light is still on? Everything is running but no picture.....keeps happening everytime...


this old monitor has 2 issues.
1: it has CCFL tubes that love to burn out (backlamps)
most this old are long go, yell,dim.,blinking or DEAD.
2: push the menu button on front of mon. turn off power saver.

3: if the PC goes to sleep, or hibernete mode (parked)
then that is 100% normal
if you dont like feature then go to windows control panel
click power, ICON and turn off all monitor sleep /hibernate modes.

that assumes windows, no OS stated.


if the lamps are dead,
use flash light pointed to sceen, see data. ? bingo for bad CCFT tubes.
as seen here

HP 2338H Monitor Goes into Sleep mode and I have to power comput


you meant w2238w , right, you left off the w?
circa 2006 monitor, 11 years old.?

if the monitor fails on 2 PC, the monitor is bad ! ok, do that...
then
push the monitor menu buttton, connected to a running PC.
if the OSD is dead, , (on screen display , menu button front of monitor)
that means the monitor is dead, CCFL tubes are bad.
cold cathod florescient laml tubes all day this old.
the menu button can be in lock mode, hold the button for 10 seconds, and it unlocks
then go in the OSD screens if they work,. and turn off the sleep timer.
this timer is marked in the OSD as power saver,. turn it off.
it is a time clocked feature, and a pain to use on modern PC.
your PC does sleep modes today and never us this timer,inside monitor (default is on, turn it off)
all that is on page32 in your manual,

Monitor going right to sleep mode on start up


Sounds like a bad graphics card. Try using monitor wit another computer and see if the problem still exists. This rules out the display.

New video card installed, now monitor won't work.


  • A vary basic failure here.
  • the OSD tells you , pin1,2,3,13,14 are dead but that is what sleep does. kills video and sync.
  • no PC stated
  • no OS stated. windows 10? what? why must beg.
  • did you turn off all sleep and hibernate in your power manager
  • click CP, click power settings click custom power profile and set all that to OFF, do not turn off screen ever. XP to now.
  • did you look in this CP control panel, DM monitor list>?
  • see my monitor, its there and not bad, if it shows bad .
  • if f1903 is missing there then your OS does not support it.
  • Right click it (internet must be connected) and say up date driver and let W10 find your driver for your OLD monitor.
  • Did you know MS drops old hardware that the maker does not support now? this is all in the PnP rules sets. but on monitors there are magic tricks to fool the system if true. this.

vga-eqk4kg0rieheuxmlwixke1cc-1-0.jpg does your monitor work on others PC, with same OS
do tell that.
does your pc work with other monitors. bingo>?
is that hard to do find another VGA port, to try, ? on someone elses PC, we cant do that here, so..... only you can do that.
hp supports it
and has this program to run and test your display


http://support.hp.com/us-en/drivers/selfservice/hp-pavilion-19-inch-flat-panel-monitors/447429/model/348757#Z7_3054ICK0K8UDA0AQC11TA930O2

last and best
ever call up BIOS?
boot pC and hit the BIOS key, called BIOS settings menus.
(HP F1,F9,10, or ESC) hint , it prompts you at boot.
does that work? omg it does so VGA is ok. right. 99% sure.
all in 5min work. you see it works
and then dies in windows x (what ever your X is)
if it dies in windows, here is the cause, (all causes)

VGA card is not bad, or overheated. bios works
1: windoz is virus infected tops that list. endless, to a fault.
2: PNP to dead, it plug and played, and killled the monitor driver or vGA driver, (less much less in w10,)
3: bad video drivers. (if hp get them from HP !)
4: internet dead, cant run PNP with no internet. not and win.
5: newer system DT< with expensive video cards the power jack cables fell off (this is only on high powered DT, like a Ausu M5a90x.
5b same deal video fan dead. overheated now.
6: PC goes to sleep, and is not anything to do with WINDOWS sleep
did you know the CPU has a sleep mode, it shuts down overheated.
some GPU do the same using the same magic hidden electronics in the GPU

if you had told what PC it was, id not have to broad band my answers. im sure i missed more,,, lacking
PC tag words.
or OS name and build.

Monitor goes into sleep mode after a few seconds


This is normaly cause by incorrect power management settings.

check power management setting in both windows and your computers bios

you will not need to worry about the power management settings of the bios when an operating system such as windows is loaded.
