But the worst ones seem to always be found or fixed by guys that have one and tell all. My worst problems are usually found on these great forums. Thx Trae Stephens and Martin Kindler I just moved and found these older laptops in a box. I have all sorts of people asking for something that just goes on the net to get kids used to computers. &quot;They only go on facebook,msn and and few others like that&quot;. Well these found laptops are just the thing. As a tech I figured no problem. More Ram bigger hdd, I have that in other boxes. So off I went, For a hole damn week to get all them running as I think they should. Gave neighbor kids to test. Two had this very same problem. I tried everything and carefully ripped apart these two a few times. To no avail, I did do a few searches and found thousands. None worked but when I read this I knew. ALL is well and the kids love the old laptops and the parents even more. <br /> This was posted Sep 21, 2004, 11:27pm EDT then again Trae did Apr 17, 2007, 01:33pm EDT and now its Sept 05,2009 10:42 pm and Im thanking all here. Funny the hard to find answer problems are usually found NOT by the companies or their Techs or engineers or anyone. 5 years later and that info saved me so much work. It worked perfect after that fix.<br /> Oh and I also decided to become a member of this community. Thx again.

I have since them gotten rid of the laptop however I did discover the issue. <br /> <br /> There are 2 cables that connect the display to the board. One is for power, it is the smaller of the two. The larger cable is for video. Compaq went cheap on the design and instead of using Gold conductors the used Silver. Over time Silver oxidizes and the contacts become weaker. The fix this problem I did the following.<br /> <br /> Remove all power sources from the laptop. Disconnect the power cord and remove the battery.<br /> <br /> Then I removed the cover over the 2 cables and disconnected them. <br /> <br /> I then used silver cleaner and a q-tip to clean the contacts on the connectors and plugs. Being very careful not to bend the contacts on the board. <br /> <br /> Let it dry over night and then reconnected everything. My problems went away for about 4 to 6 months and then I would have to repeat the process.<br /> <br /> Now if you do the above do so at your own risk. Over the course of a couple years I did this and then one day as I was taking things apart I got side tracked by one of the kids. When I got back to my little project I forgot to remove the battery from the laptop. As soon as I put the silver cleaner on the power contact on the board for the LCD it went up in smoke. Luckily it was the Audio/LCD board that the LCD connected too and I got one on E-Bay for about 20 bucks. I replaced it and I was good to go again. Ultimately I got tired of cleaning the contacts and eventually the plug on the LCD came un done. The wires came out, I guess from unplugging it so much. I just removed the LCD and connected the laptop to a 17” CRT for my daughter so she could have a PC that would fit on her very small desk.<br /> <br /> In regards to the HP with the same problem. You could be having a similar issue, maybe not. You may be able to search on the internet and find out what type of material was used on the contacts for the LCD connection.<br /> <br /> Trae <br /> text/html 2007-04-17T03:11:16-05:00 alice b http://www.hardwareanalysis.com/content/topic/830/?o=20#486535 my hp does the same thing. I wish i could figure out what the problem is. I think it may be loose wires that go through the hinges from base to screen, because sometimes it quits if i move the screen a bit.<br /> <br /> The problem has caused my backlight to burn out twice (not cheap). <br /> <br /> Does anybody know what the f'n problem is? text/html 2006-11-21T09:46:37-05:00 russell hankins http://www.hardwareanalysis.com/content/topic/830/?o=20#460665 I own a COMPAQ ARMADA 1750 6333/T/6400/D/M/3 laptop. Can someone tell me how I may enter the setup bios. F10 does NOT work. I tried an array of other keys with No luck. I am running Windows 98SE. This laptop does NOT boot to A:\&gt;drive with either a setup floppy or CD Windows 98SE. I tried to download a user manual, but I can only find 1750 family. I would appreciate if someone could send me the URL address for this laptop user manual. Many thanks in anticipation. Russell Hankins.

You will see the screen on your standalone monitor without any problems and when you have switched back, you will have your screen back on your compaq. <br /> <br /> Maybe there is a way to build only an vga connector with a stand alone monitor to switch &quot;virtually&quot;.<br /> <br /> Christof text/html 2006-05-31T16:42:22-05:00 Joseph Jacob http://www.hardwareanalysis.com/content/topic/830/?o=20#417529 i have a compaq armada 1750 which has display problms.. the display looks small on my monitor... i dont know how to make it big.... <br /> <br /> my laptopn only shows 2 types of resolutions in the Display Properties..... cant find the rest of the resolutions options...... <br /> <br /> i dont know what its all about.... got any ideas...... ?? text/html 2006-03-27T21:37:33-05:00 Geoff Bedford http://www.hardwareanalysis.com/content/topic/830/?o=20#399926 This worked for me (for both the white screen and the 'black' screen problem)...<br /> <br /> As the craptop starts up... press and hold Fn key and the F9 key together *and* continually tap the F11 key. This should take you into the 'emergency' BIOS option. Once you are there press F1 to reset &amp; save the BIOS.<br /> <br /> After the system reboots, you will need to reset the time &amp; date.<br /> <br /> Good luck!<br /> gef<br /> <br /> P.S.

I am deciding to replace the white connector of the screen. Is there any one knowing what is the model of the white connector? Is it a standard connector and can be easily got from the market?

Since a two days ago, when turn my computer on, after a few moment, generally when windows starts loading, two bip sounds. Is this a kind of message?? <br /> <br /> Thanks a lot.<br /> <br /> text/html 2005-05-18T03:20:09-05:00 k k http://www.hardwareanalysis.com/content/topic/830/?o=20#276997 Thank you so much for the advice to unplug and replug the wires beneath the keyboard! We had the exact same problem - the screen went white from top to bottom, the rebooted and was fine. Then the next day it flickered and then went black 50 pages into a final paper due the next day. Lifting up the keyboard and unplugging the wires, waiting a bit, replugging them in, and restarting did the trick. We selected option F1 to save the changes made (an error message came up on the Compaq display), and then Windows loaded up as normal. The 50 page paper was retrieved! Thank you again. text/html 2004-10-31T18:29:32-05:00 Jorge Cornejo http://www.hardwareanalysis.com/content/topic/830/?o=20#199436 I had the same problem, i believe it's the cmos battery but not sure. What i do is to unplug the cmos battery wires that are located below the keyboard, disconnect power and battery, also the white cables that are also below the keyboard and wait 1 minute or more. Replug everything and you're done. It'll start again.<br /> <br /> The strange thing is that if you press F8 during the system start up (before the compaq logo) you'll see the System Restore Menu, but any of the options will boot the OS, that's why i believe it has to be the CMOS battery. text/html 2004-10-08T19:22:21-05:00 Predator http://www.hardwareanalysis.com/content/topic/830/?o=20#191303 Have you had anything magnetic touch or get really close to the screen?

After pulling the laptop out of retirement a week ago and loading XP on it the screen began to flicker similar to what has already been described. Then during a 3D game it just went black. Now when you reboot the laptop the compaq logo comes up and then the screen goes black even though you can see there is still power to it. Do you think this also has to do with the LCD connector plugs? As the compaq logo is perfect, just nothing comes up after it. Im going to try some of whats been sugested already but any other help would be much appreciated. text/html 2004-10-03T01:26:02-05:00 Allen Cuthrell http://www.hardwareanalysis.com/content/topic/830/#189561 This is very disturbing problem with the Armada 1700's and 1750's. I have read many posts on this and feel that this may only <br /> <br /> be a mechanical hardware problem.<br /> <br /> I have suspected for some time the contacts between the LCD and the mother board. These are the white and black connectors <br /> <br /> just under the left hinge cover. <br /> <br /> I have heard about oxidation buildup on these connectors causing the screen to &quot;white-out.&quot; This comes from a faulty <br /> <br /> connection with the WHITE connector. The Black connector is for the inverter for the back light.<br /> <br /> I decided to CLEAN these contacts on the WHITE connector by purchasing some Tarn-X (tarnish remover and silver polish) from a <br /> <br /> local drug store. First I powered the computer off and remove the battery. I dipped the WHITE connector into a small tray of <br /> <br /> Tarn-X after I unplugged it from its motherboard socket. I let it soak only for 30 seconds and then removed the Tarn-X and <br /> <br /> then dipped the same WHITE connector into water as a rinse. After a few seconds of water I used canned-air to blow out all <br /> <br /> water from the connector and then allow it to dry for a half day. All this in taking care NOT to get any solution into the <br /> <br /> computer because it would ruin it! If you want to be super cautious remove the entire LCD with its bezel from the base before <br /> <br /> you attempt any of this.<br /> <br /> After all is dry I plugged in the white connector and my display has been rock solid ever since!! Even a little brighter, I <br /> <br /> think.<br /> <br /> NOTE: I only cleaned the white connector, however, it wouldn't hurt for the black connector to be cleaned too. DO NOT put any <br /> <br /> solutions into the socket (pins) of the motherboard. The Tarn-X will short out signals between the pins with it residue. <br /> <br /> Thats why we rinse with water and then air dry. <br /> <br /> Let me know how yours works out! It won't hurt anything to try it.<br /> <br /> Link to Tarn-X<br /> <a class="ext" href="/action/r/http://www.jelmar.com/TarnXGroup.asp?p=TarnXbasic" target="_blank">http://www.jelmar.com/TarnXGroup.asp?p=TarnXbasic</a><br /> <br /> Allen Cuthrell<br /> Piedmont, SC
