    compaq presario v5000 very old (13) laptop.
    ok this is more clear. V5000
    the cause of black screens
    no text?
    but fan blows?
    and hdd spins (both can be heard)?
    are bad CCFL lamps inside the LCD screen
    using a flash light , in dark room
    point to screen turned on PC fan spin .
    see data, yes, then CCLF are dead tubes.
    as most are now, CCFL ended in 2010,
    hint 5year newer then your relic PC.
    LED started in 2010
    your PC is 13 years old now, made 2005
    never seen good screen that old now.
    they burn out long ago in most cases.
    unless parked in closet for 10 years.

    click flashlight here.

    power on.
    fans spins
    hdd heard to spin
    screen black out comes a flashlight,

Seems to be a known issue on this model. Attributed to a bad video adapter on the motherboard. Also says to check the the memory is correctly seated which fixed one 'black screen' scenario. Read the link

Attach the laptop to an external monitor to confirm. If you do get a picture, it is the display.

    that link is about generic laptops and is mix of all years, not worth reading really.
    why not ask real techs what happens,?
    most posts on the web are wild guessing and no testing at all, and folks mixing up makers,models, years in toxic soup of lies.
    best is to focus on one model PC. only
    and for SURE YEAR Made.

    it is true the information age is 1/2 lies.
    you can read anything you want on the web.
    What matters above, is the OP is not clear at all, no facts presented.
    so answers will be endless guessing ....
    Q1: is the fan silent and hdd dead silent.
    Q2: does it run Big battery out.
    Q3, your coin cell battery is no good, why expect that if 13 years old.
    Q4, the flashlite test, above ok..

    So what is your advice Larry?

    Larry Ng Oct 23, 2018

    THE OP PC was made 2005 year,!!! this is key
    13 years old today.... age always matters.

    fact 1, most seem to forget, age matters.
    CCFL tubes are dead, all PCs or monitors this old have long ago failed the CCLF lamps. all do. (endless posts here on it )
    or the CCLF inverter dead, (very rare)
    I can only guess, the OP failed to hear the
    Fan blowing and the HDD Spinning
    and did hard them spin, then tried the VGA jack to a VGA monitor and wow the monitor works,?
    then shinned flash light at the LCD screen
    and SAW DATA on screen now, bingo CCFL dead.
    we do this on all old laptops older than 2010 LED year line of change.

    if run for 8 hours a day for 5 years then CCFP are dead, this is the #1 issue on all old PCs, with CCLF lamps, it's not new idea or magic or rare. LED lasts near for ever, CCFL are short lived tech. (CCFL yeah suck)

    but worse than that (age matters ) the old laptop battery shorted, overloading the power buss.
    remove the battery large first.
    this is all SOP. every word by year,

    never keep 13 year old batteries around the home this old. ok>? some catch fire
    buy a new one and new fuses in battery end the fire deal. IMO

    Larry Ng Oct 23, 2018

    that link above is by folks that think all laptops are the same, sad.
    in fact not one good test shown there,
    for sure not this...
    1: sounds, does the fan run and hdd spin,
    heard? it must or power is gone, and dead.
    surely this is easy test, just 1 ear to casing, the fan can be felt and heard or seen if keyboard pulled, omg packed in lint after 13 years of dog hairs inside, omg.
    2: screen dead but you see data on the LCD in a dark room with flash light pointed to the LCD at an angle. omg CCLF tubes dead.
    3: OMG the PC runs perfectly with battery large out. it died 13 years ago but shorted out today. bingo, run on AC for ever, battery out, or buy a new battery.
    4: OMG3, the RTC 7 year max coin cell went dead at 13 years old, and BIOS went nuts
    as it surely will, in every case.
    5: what if all above fails to fix it., sure.
    we can do that.
    run the PC on 1 stick of ram, mine has 4 sticks, 2 top ,2 bottom , the 2 top is keyboard out, step 1.
    test them1 stick at a time to see if all 4 sticks of DDR are good. 1 by 1.
    6:ok RAMS good. its just PC and things fail , and all do from entropy.
    7: ok the screen works, BIOS works, new coin cell made nuts BIOS work perfectly. now.
    I now test the HDD fully with Smart tests.

    end, page full,.

  • Larry Ng
    Larry Ng Oct 23, 2018

    continued, new page
    if the Laptops with bad CCFL this old are just a thrown away.
    it is only worth $20 used and bad.
    so why spend $100 or more on $20 pile of junk 13 years old.
    worse is new CCFL + HDD, + new OS.. wow
    and labor, crazy high, ok?

    econ 101 says, junk it.
    in fact go to Walmart page,
    buy nice good PC with W10 on it , refurb
    for less than $100
    even a new chromebooks cheaper than fixing this Compaq pig.

  • Larry Ng
    Larry Ng Oct 23, 2018

    order of failures are. in order if timed failures for sure.
    Bad main battery and coin cell too.. for age.
    bad CCLF (20,000 hours, dead)!!!
    BAD HDD. (5 year par for crummy laptops)
    all 3/4 are short lived parts,
    other parts inside can last for many decades.
    Most chips do. (intel inside deals)
    not the fan.
    the other top failures is PC packed in lint
    and overheats, but HWinfo32.exe tells you it did. so is childs play to use and learn.
    90C is overheat and self shuts down. in all cases, AMD or intel.

    the other horror is 2008 year, Nivdia chips failed, GPU BGA, solder balls melted.
    USA EPA mandated lead free and this failed
    out the gate, there is a wiki dedicate to this topic and is not magic or unknown.
    it's real deal. that failures.
    the trick is to twists the bottom case.
    and see lines on screen change or black screen turns good or UGLY
    and is the BGA failures , that year.
    horror 3, is China cloned caps debacle.
    called the Plague. by wiki.
    1999 to 2007 (bingo?) OP is 2005 .
    I've cured many of these, back then before I retired,

    the cause is blind greed

  • Larry Ng
    Larry Ng Oct 23, 2018

    the greed was the card makers, video, motherboard, etc.
    The could not side step temptation of buying 3 cent caps, from China/Taiwan no name companies.
    and not from Japan, famous, Nichicon.
    the caps failed by the 10s of millions.
    today fast forward and the Asus sales ad. states "our boards use Nichicon ".

    dang. what a shock.

Cant get my screen to read. it is black/blank. Is there a reset button? Compaq pesario v5000 lap top

SOURCE: Compaq Presario v5000 won't turn on

If the laptop posts: (power on self test) and you see stuff on the screen, no matter how short ,do the following:
if you have a bootable anti virus disc use it to check for any viruses , if not
try a recovery disc,
both will try to access the hard drive.
if they do not work,(nothing has changed) nothing comes on the screen.
laptop does not post:
remove the screw(s) holding the cover plate where the ram lives
remove the memory sticks, clean the gold edges with a pencil eraser both sides and re-insert them, (not an ink eraser as it will do damage)
swap them around if you have more than one,
if you only have one, borrow one from a friend or try the ram in your friends laptop ,if that's possible, or take the ram to your local pc shop and ask them to check it for you (they may or may not do that for you)
if you can establish that the ram is ok, and anti virus and recovery disc's do not work,then it is most likely, the motherboard has failed .
good luck with that and let me know how you get on.

SOURCE: I wish to format my Compaq Presario v5000 and

Good day sir/maam, yes let me be of assistance to your task of formatting your Compaq.

Power on compaq and place your windows XP CD installer on the CD drive.
Here are the events that will take place.

  1. You need to boot the CD inside the drive. Go to CMOS setup (usually you press F10) and locate the first boot option, set it to the CD drive. save and restart.
  2. If the boot from CD appears press spacebar, or any key to start the boot process.
  3. At this point windows will load the series of files needed to setup windows. wait for it to ask you a question.
  4. You will arrive at a point to create a partition or where you would like to install the windows Operating system, we usually select C drive.
  5. Next is you need to choose what kind of format you want on the C drive, just choose NTFS, be it the long format or the quick one. (quick format mean the drive is only erased).
  6. Wait for the windows setup to restart, then the CD setup takes over the setup process. Wait for it to ask you questions on where you are, country and the likes.
  7. After setting it up, the XP setup will ask you the 25 letter/number serial code that can be found on the CD case.
  8. the setup will restart, follow the instructions on how to register your windows, or just skip the the process, you can register it later.
  9. On the input login names, place your name and add extra names if you want as login name.
  10. The windows setup is done, you now need the CD that comes with your compaq laptop, to setup all the devices on it, such as sound, video, usb, lan, etc. your done.
If you have questions or met errors along the way, feel free to ask, or if you have a friend who knows how to set it up, ask for help.

sp31891.exe is the HP/Compaq Softpaq that helped me see that the wireless was enabled, but had some kind of software funkiness. It may also contain the driver for the wireless on/off switch for the Presario V5000 series. The particular unit I was working on was a V5005us .
