Receives beeps on boot then nothing

Bought a used compaq 1700 I was told that the monitor stopped working so i connected an external monitor to it, added memory and on booting up I receive 4 beeps then nothing. Shows power to the battery and after being on a while the fan kicked in.

    Ok, I got video using the vga port, I had memory in it and it still gave me the beeps. I don't know anything about a "reseatedor", but I think that I have an idea. You mean replace the units in which you seat the memory correct Calvinrueb87? The bios info was good as I am working on other units. I swapped out to another board of the 1700, but now this board has a sync problem as I can't boot to Knoppix on it. Or any other linux disc.

I can tell you now that the display adaptor is no good. (standard for four short beeps) If you want to look up the page to get this info off of here it is

I'm not sure if your computer has any expansion slots for video. The reason the fan is kicking on and the lights come on is because the computer continues to boot without the video.

Most likely the ram needs to be reseatedor replaced.

    Sorry, that was a typo, it was reseated, just the process of removing it and putting it back in place. Sometimes the contacts loose connection and need to be reinserted to get a better connection.

    Since you have video, that is a different story. The fact that it boots does not say the ram is not bad, but none of your current problems point to it, so i wouldn't look into new ram unless you are looking to upgrade.

    Could you elaborate on what you mean it says "not syncing?" The other thing to try with the monitor situtation is to make sure that it is not just deactivated. Most of the time there is a funtion button to swap between the video modes. On most laptops there is a Fn button in the lower left of the keyboard and it is a different color then the rest of the keys. Then the F1 through F12 keys also have icons that have the same color, holding the Fn button activates them. You are looking for one that either says CRT/LCD or has the picture of a monitor. This will usualy swap between 3 modes: Just LCD, Just external, or Both. On most laptops, without an external plugged in it would default back to the laptop, but just in case that system is not working i would just try it.

    In the event that the monitor on board has failed, there are a few things to look at. a singel beep at startup and signal that the Power On Self Test (or POST) has completed, other times it does mean there is a problem. it's hard to say model to model. There are two seperate systems to the monitor. There is the portion that supplies the image and there is the system that suplies the light. If you can faintly see the image (may be very dificult without alot of light) then the back light has either come unlugged or unhooked. If you see the screen fliker (even staying black) but no image, then the video signal may have come unplugged.

    I've worked in simular laptops, but not the exact same one, and on the ones i repaired i found that i could remove the keyboard with two screws on the bottom (labled with a keyboard icon) and on the top of the keyboard there were three clips that just slid down. you may be able to try to reconnect (even if they still are, remove and reinsert them) the cables.

    I'll leave you with that for now, if no luck, post a comment and I will try to help you further.

You can switch to anexternal monitor by two methods.1. Connect the externalmonitor to the laptop's video port, power up the external monitor first and thelaptop. The video information will automatically switch to the externalmonitor.2. If you power up thelaptop first then you can switch the video output to the external monitor bypressing the Fn key and one of the Function keys, depending upon your make andmodel laptop. You can also toggle between the external monitor or both LCDscreen plus the external monitor or back to LCD screen only by pressing the Fnkey plus one of the function key.

Compaq 615 laptop just hung, i removed the battery then tried to boot again but showed nothing


Not enough information.

It would be helpful to know if this machine running XP, Vista or Win 7.

Can you hear the CPU beep during boot?

Do the lights come/blink on on the front of the laptop?

All this information is important if you want accurate advice to help solve your problem.

If you have a desktop PC monitor available, connect this to the laptop's VGA port and press the Fn (function) key simultaneously with the F5 or F6 key (the key showing 2 monitors) while booting, to send the image to the external monitor.

If you can see images on the external monitor, then your laptop may have (in ascending order of seriousness/cost of repair), an LCD panel inverter fault/failure, a cold cathode backlight fault/failure, an LCD panel fault/failure, a graphics card fault/failure, a motherboard power management system fault/failure, a motherboard fault/failure.

Sorrry to not be able to be more precise.

Hope this helps.

Power up the external monitor first and then boot up the laptop, the video info will automatically divert to the external monitor.
If you do not see a Windows image on the external monitor then it is definitely a motherboard issue, because the video card is built in on the motherboard.
The Video card uses shared RAM (part of the RAM module/s ), try re-seating the RAM modules, also test the RAM modules.
You can test the hard drive by removing the hard drive and connecting it to an USB hard drive adapter, then connect the adapter into a working computer's USB port. If the hard drive is OK, this computer will see it as an external storage device and you can open the various folders and files on the hard drive.

Is it possible to bypass the built in screen monitor(compac 7770 DMT) and connect to another computer monitor. I bought my laptop at the local goodwill store and the monitor just looks like wet splatter....

1) connect your external monitor to the 7770DMT and switch it on
2) boot up the laptop
3) after it has successfully booted, you need to identify which function key toggles the external monitor on/off
4) you should be able to do this by holding down the Fn key and trying each of the F keys in turn, waiting a few seconds after pressing each one
5) begin by holding down "Fn" + "F3", "Fn" + "F4", "Fn" + "F5" etc.

My compaq presario do not start, instead it make two sounds like a beep and then nothing, what coulds happen. it is the mother board or is the hard disk?

It is from the mother board which means that there will be some errors on the motherboard ,if the booting is not done in proper way then .The mother board produces beep sounds. better re-install the operating system first , then check that the sound is producing or not , else better contact a compaq service center. they will be able to fix it for you.

Laptop will only boot/power on when external monitor is attached

Sounds to me like you have a short inside your system somewhere, or you have a faulty display/graphics card is going bad. You will probably have to replace your display and/or graphics card. On most laptops, if they dont have a dedicated graphics card, and they use an embedded one, then the whole screen has to be replaced. if the graphics card Is dedicated, then you probably can just have the card replaced, and not the whole screen.

Compaq Presario V2000 fails to boot up

3 beeps is the Beep code for "Base 64KB RAM Failure". Lets hope that you are lucky and the problem is your memory. If you have two memory sticks in the computer, then try to take one of them out. Try different combinations such as swapping between the memory slots that are available. If you still getting the same error code, then your motherboard is shot.
