Question about HP Computers & Internet

1 Answer

HP m9510f will not boot up.

Monitor light goes from orange to green. All the fans are on. Seems like the hard drive quits after the monitor light goes green. Then it starts to beep and sounds like something one would hear in a hospital. Every once in while you can hear the hard trying to do something. Recent self test found no problems. Turning it on and off does not have any effect. Pressing any of the "F" keys during start up does not help.

No boot M9510f,
no boot is like the all time #1 complaint on PCs.
endless posts online on this and for sure at HP.. ever read their forums?
there real name is (and is supported still at HP) is
HP Pavilion Elite m9510f Desktop PC
no statement on screens, is the screen dead, and black
never once see HP logo, never see words to the effect
hit ESC to enter HP setup (BIOS) or F1 or F10 or????? do tell please.
that is first, forget windows now (its LAST)
screen model or maker stated ,
my guess a flat screen LCD
and the front button on it works and the screens local OSD menu works, right?
if PC is dead, the screen is checked first. for sure if BIOS screens in the PC are 100% dead, no text no F1,ESC,F10 keys prompted in text means PC dead or SCREEN dead.


here is HP page on your pc
https://support.hp.com/us-en/product/hp-pavilion-elite-m9500-desktop-pc-series/3824167/model/3876396/troubleshooting


here is black screen tests.
the screen (DISPLAY monitor) has its own brain
and is called OSD, on screen display
we check that first. always........ if screen is made before 2000 year
we trash it.... LOL (before first brains inside )

black screens, Desktop only.

SOURCE: Asus P4S800-MX Motherboard video problem

The system speaker is usually a set of four pins and you use the outside pair to connect the speaker. You may need to go to the Asus web site to download the manual if you don't have it. Try to reset the bios either by shorting the appropriate pins or by removing the battery for a while.

SOURCE: HP desktop monitor problem

hi try this ,,,

  1. Ensure the video cable is connected (and connected to the correct video port).
  2. Turn off the monitor using the monitor's power button and then restart the monitor.
  3. Cycle the power on the monitor as follows:
  4. Turn off the monitor. The power light on the monitor should be off. Leave the computer turned on.
  5. Unplug the power cord.
  6. Wait 5 seconds.
  7. Plug in the power cord.
  8. Press the power button on the monitor to turn on the monitor. One of two things happens:
    1. The image from the computer displays on the monitor and you can use the computer again. This indicates that the monitor was unable to detect that the computer had awakened from suspend mode. Turn the monitor off when it is not being used or disable suspend mode. For some computers, updating the BIOS corrects these types of suspend problems.
    2. The power light on the monitor comes on but the screen displays one of the messages again. The monitor is not receiving a video signal from the computer that it can detect and use. Continue using these steps to adjust the Windows display resolution to the Monitor's native (default) resolution
    3. Connect the monitor to another computer that you know is working to determine if the monitor should be serviced or replaced:
      • If the monitor displays an image from another computer, you know that the monitor works. Troubleshoot the video connection and graphics adapter on the computer.
      • If the monitor remain blank when connected to another computer, the monitor signal processing hardware may be bad. The monitor should be repaired or replaced.
      hope it will work for u .. little_angel

Compaq presario sr1950nx monitor wont turn on the usual green indicating its on is now orange...tried to inspect the video cable and video connectors for damage its seems fine.....the hard drive is working...


It sounds to me like the computer is coming on but not booting. That is, there's power but it isn't actually starting up, so no video ever gets to the monitor. Until there is a video signal from the computer (you're calling it the hard drive), the power light on the monitor will stay orange. Also, the power supply fan in the computer spins at maximum speed until the computer starts up, and that's likely what you're hearing that sounds so loud.

Unplug the computer's power cable and remove the side panel. Make sure the memory modules are firmly seated in their sockets. This is a common cause for computers not booting. You can download the upgrading and servicing manual for this computer from HP's site here. This will give you all the instructions on how to open the case, where to find the memory and how to remove and reinstall it. Also be sure that all the internal cables are properly seated as well. Plug the computer back in and try restarting. Most of the time this will get you running again.

If the computer still doesn't start, the most likely causes are motherboard failure or a power supply problem. Unless you have access to parts to substitute for testing, your best bet is to have a computer service shop check it out for you and give an estimate for repair.

Good luck and thanks for using Fixya!

Yellow power light on HP SR1420NX


For reasons yet to be determined, your computer is not talking to your monitor.

This could be the monitor cable came loose from the tower (this is our favorite, because it is such an easy repair), or something on the motherboard (that is, anything) that is not functioning and preventing your computer from starting.

Unplug the connecting cable, and plug it back in again, making sure that it is seated properly.

Do you hear any sounds besides the fans? You should be able to hear the faint clicking of a hard drive starting up also. If you hear this, the problem is not in the computer, but in the communication to the monitor.

Good luck

Pc wont read monitor


If you look at the monitor there will be an led light on the front that is always orange or yellow when the computer is off but still connected to the monitor. This led will turn green when the computer boots up, sometimes even showing a "no signal" display before boot. If you see the 'command line'  text during the boot process (video info, BIOS version, POST text, etc) then the monitor is being recognized by the computer. If that text goes away and the led goes back to orange then it is a driver or operating system problem. Pressing whatever key is prompted at the lower left of the display, if you have a display, like F1, F2, F10, Delete or whatever will get you to the setup program and all is good with the display/computer connection and a green light will stay on. If you never get that green led light then either the video card is bad or not seated properly

Black screen not booting


check both your power and video connections to the monitor, sounds more like a monitor power issue.
if the connections appear ok, but screen still blank, try connecting a known good working monitor from somewhere else and see if it works with your pc, if it does, your original monitor is faulty, if it doesn't, you have a pc video issue.
