I am running Unix Tru64 5.0 on Compaq Alphastation XP1000. The computer does not boot and does not display anything and does not beep. The power supply works and some LEDs are on on the logic board and the CPU and chips become hot. Replacing the VGA card did not help.


Hi.first pull-out your motherboard in the CPU case then power on without memory only processor installed.if you hear continuous beeping your motherboard is working good.
try this beep code means.

No beep means short,no power,bad CPU,loose peripherals.
One beep means everything is normal running motherboard.
Two beep means CMOS error IC.
One long beep,one short beep means motherboard problem.
One long beep,two short beeps means video card problem.
Three long beeps means keyboard error.
Repeated long beeps means memory error.
Continuous hi-lo beeps means CPU overheating.

Hope can help you.

I did not mistreat my computer in anyway. If the computer does not start up even with the battery charger in and everything, what does that mean is broken? The harddrive or the motherboard?


If when you press the power button NOTHING at all happens then the motherboard is bad.

If you turn on the computer and the lights all turn on but nothing else happens then the hard drive is bad.

If when you turn on the computer and you hear the hard drive start, the fan running and everything else seems to be working then your video card is bad.

Cant get computer to


Disconnect everything from the motherboard except the power supply, CPU and power switch.

Turn on the computer. You should hear 3 beeps because you removed the memory.

If you don't hear any beeps, check the power supply. Check all the connections. Did you connect the 4 pin power? Did you skimp on it? A common mistake is to get a cheap, high-power supply. Just because the box says it's 1000 WATTs doesn't mean that will carry a steady load.

Still nothing...

It's either a bad motherboard or processor. If you have another processor that is supported on that board and you know it works, try it. If it boots return your CPU for a good one.

Unfortunatly, if it doesn't boot with a known-good processor that just proves the board is bad; it doesn't prove your CPU is good. You may have more issues.

no display on screen and solid amber light on pcs' power button


To el_cid_132: Did you mean to say a solid amber light on the MONITOR's power button? If, after all you've tried with the computer, you still have no display, it's a pretty good bet your monitor is bad. Try another monitor to verify the computer function. Take a close look at the pins in the monitor's input cable plug. They are pretty easy to bend, and you may have one not making contact.

To Jaffe: It's a simple job to remove the hard drive from your laptop and hook up to another computer to copy anythig off that you want to keep. I don't know what a shop in your area would charge, but it should be reasonable. As for replacing the system board, a quick Google search for "MX6448 motherboard" turned up several sources, price range $250-$300. Usually it's not worth putting a new system board into a laptop unless it's a very high-end model. You can buy basic laptops now for around $400, and you'd be getting brand-new with a warranty.

no display


So turning on the computer doesn't bring the monitor out of standby? Just to be sure, try turning the monitor off, then on again and the Pc on at the same time. If you see any writing on the screen, that will be good news. Make sure it isn't just the cable to the monitor. It is possible to mess up the connector on the cable where it goes into the computer. If one of the pins is bent, use tweezers, to very carefully try to bend it back. If it breaks you have a big problem - have to find another one and splice it onto the cable or replace the whole cord. Still nothing on the screen. Could be the monitor. Could be the video card, the motherboard, the microprocessor or the power supply. The worst case is that the old power supply failed drastically and destroyed all of the above. Try your monitor on another computer. Any sounds coming from the computer when it starts? Startup music would be a very good sign - most everything working. Any beeps? Three beeps mean the video card has failed but the motherboard and processor are probably okay. I can't think of an easy way for you to test the motherboard and processor. If you have access to a similar computer, you could try swapping in a known to be good video card. It sure looks like the worst case scenario.
