Have compaq presario v2000 notbeook. was beeping twice upon boot up, replaced the memory as that was the error code I found online, now it gives off one long consistent beep right after the compaq screen comes up but before the windows xp screen comes up. It does boot but then you can do nothing as everything you try hangs. Any clues? Thanks

    There was a 256mb memory chip in the system when I got the initial 2 beeps. I replaced it with a 512mb chip (both are 200 pin, 333mhz) and now it went from two beeps to an extremely long beep. There is no built in ram that i could find from the specs. I did diags from the BIOS and the system sees the 512mb of memory. I will have to remove the battery when I get home from work and see if that works. Can I reply tonight once I try to unplug everything?

  • pekala13 Mar 05, 2008

    sorry
    specs for the laptop are up to 2gb of memory, there are two slots. I replaced a 256mb with a 512mb, which is a supported config.

    I unplugged everything and had the same result. Put in another memory chip, same thing. Put memory in both banks thinking one bank was iffy, same result. I can bypass the beeping by holding down the esc key at boot up but still cannot really do anything when the system comes up. The system doens't initally beep, it goes to the compaq screen, beeps when the screen fades then a black screen with a blinking line appears (still beeping) and then the beeping stops as the windows screen appears. When you say main board, do you mean the motherboard of the system? or is it possible to just replace the memory portion of the board?

    It ended up being a defective keyboard. One of the keys caused the never ending beep. Replace the keyboard and all is well.

Does this also happen without the battery inserted. Unplug everthing possible including DVD drive and external devices.

According to this site: http://www.bioscentral.com/beepcodes/compaqbeep.htm one long neverending beep is also bad RAM. If you've replaced the ram then the only other explanation is the memory controller on the main board, looks like you'll have to replace that too. First check that the RAM is inserted properly. Try a single RAM module if possible. Does this unit have built in RAM? If so then the main board needs to be replaced. Also make certain that your new RAM is the proper type and speed.

Good Luck!

    That would indicate that either your new RAM is also faulty or that the main board is faulty. Try some more RAM, try to borrow some, if same problem replace the main board. Otherwise buy more RAM. Lookup MEMTEST86, it's a great memory diagnostics program that you burn to CD, use it to test your RAM.

    Motherboard is correct, and no the memory slots and memory controller are part of the motherboard unfortunately. Ebay should have some motherboards for this model for sale, if it's a few years old you may be in for about $200~$250.

    That makes a lot of sense now!!! You always think the worst when you hear beeps it thru me off, especially since the beep codes site I found had an entry for a long neverending beep. It didn't occur to me that you were describing neverending short beeps. Good on you for finding it out.

Only long beep tones with a few seconds pauses


depending on the beeps, you are looking at usually memory or video card error. first step is to remove the memory from the system and place only one stick in at a time. if the unit only has one stick then you need to get a known workign stick to test with. if the known working stick works or only one of the other sticks work then check each of the slots indvidually. if you find that the unit does not boot with the memory in a specific slot, then you have a bad motherboard. if the unit boots in every slot with the good memory, then you have a bad stick. If the pc boots after pulling and reseating the memory, you got one of the rare issues of a memory stick lossening up. If nothing boots it, then you need to move on to either the video card or motherboard.

Without the exact beeps and length of each beep i could not give you more than a generalized answer.

Beeping upon startup and nothing else.


You need to check the RAM that is the first causes of beeping your system unit. Try to remove the RAM and clean the dust and re insert it. Try to use the other memory slot. You can try it 3 times. Thank you!

MY LAPTOP(hp compaq presario v2000)BEEPS


hi roman razumo,

these are common infos you can see on beep codes.

if you have AMI, your computer has memory problems. First check video. If video is working, you'll see an error message. If not, you have a parity error in your first 64K of memory. First check your SIMM's. Reseat them and reboot. If this doesn't do it, the memory chips may be bad. You can try switching the first and second banks memory chips. First banks are the memory banks that your CPU finds its first 64K of base memory in. You'll need to consult your manual to see which bank is first. If all your memory tests good, you probably need to buy another motherboard. (more info on this click here)

Unable to reboot CPU


when its powering on let it get a little ways in then hold the power on off button until it just shuts off. Then boot it on and see if it gives you a safe boot option if it does select it. Then do a system restore to before this problem started. Hopefully this will restore the drivers.

Won't pass startup bios / screen


Make a note of the number of beeps and whether they are long or short. Put the old video card back in the machine. Go online and do a search for "bios beep codes", check what you wrote down and see what the problem was. It was probably a video error. Perhaps you should install the video drivers for your new card before you install it, that way it might avoid the error on startup.

Boot up problems


If it won't go past the splash screen, and you have replaced the CPU, I agree that it is probably the motherboard.
One other test you can do is, remove the memory chips, and any cards that are plugged it, and see if it beeps on start up.
If it does, count the beeps. If it doesn't it is the motherboard.
If you get beeps, plug the memory back in, and try again. Listen for beeps. Let us know what you find.

And I don't know if Compaq's do this (Dells do) when you turn it on, do the fans spin up normally? Or does it sound like a small jet? Speaking of which, do you see the fans spin up at all?

Compaq Presaio S4200NX displays Compaq Splash Screen then a single continuous beep with but nothing else.


Hi,

Most Compaq desktop that exhibits 1 long never ending beep indicates Memory error; Bad RAM. Corrective measure therefore would be replace and test.

You can try removing the memory and cleaning the gold pins with a pencil eraser and try again. If this doesn't work, guess you're back to replacing.

Good luck and kind regards.

Long flatlined beep when powered on


According to HP your machine should have pheonix codes. So i'm guessing that is very bad :)

Have you tried reseting the bios yet?

How about trying different memory, or just removing any extra memory.

Looks like you will have to TS this one old school. Trial and error.
