Monitor with amber light

by simpson / November 5, 2005 5:32 AM PST

Hey guys. I have a question. I am currently working a on compaq presario 7922, Win 98 not sure on the processor because its not mine. The problem is the monitor displays nothing. As soon as you boot the machine the monitor green light flashes and then turns amber. I figured that the integrated vid card went bad because the monitor works on other machines. I install an extra vid card I had but this didnt fix the issue. So I dig a little deeper. I check the power supply just to make sure the system is getting the power it needs and it does. So the power supply seems to be ok. I noticed that the keyboard lights doesnt light up as the system boots up (system boots up == all cables connected and fans/tower lights are fine). Now the issue could be a mobo problem, but I'm not 100% sure on this. This is just another thing that it may be. Speaking of the lights not flashing, whenever I unplug the keyboard while the system is on, you can see the keyboard light come on and then right back off. So it seems that the mobo is "somewhat" working. I also suspected the Hard Drive because the windows logon doesnt sound when booting guess the sound is not muted because the user never mutes the sound. Back to the keyboard, I also tried holding hold a key during the bootup to see if it would get a keyboard error.

That about all the things i have tried. Can anyone give any suggestions or what youe think.

Did you disable the onboard video
by Ray Harinec / November 5, 2005 5:55 AM PST

in the BIOS before you tried the plug in video card???

Does it seem to be booting normally [except no video]. Any chance that the CMOS battery is bad, thus preventing successful POST / boot??

By the "power it needs" you mean that the main 5 volts is in spec, the 3.3 volts is in spec, the 12 volts is in spec, and the PowerOK signal changes state shortly after the main rails are turned on.

Re errors, remembeber that in the BIOS, one can set it to not show any errors. Thus maybe why the keyboard test didn't work.

Can't disable

Well, I can't disable the onboard card because I cant see on the monitor to do it. I did change the cmos battery and still nothing. I also connected the hard drive to a different machine and it boots and the monitor displays compaq. I also tried another hard drive in the machine that is having the issue and nothing happens.

If you have an old PCI video card laying around, you may want to give that a try. It will usually disable the on-boad when you put in another card. That's my best suggestion.

I have already done that. I put in the pci card and it's still doing the same thing.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
