Question about Compaq SYSTEM BOARD PRESARIO 1900XL (174104001) Motherboard

2 Answers

I have a problem, in short. I took my Compaq Presario apart to disconnect the internal battery, replace the faulty 3.5'' disk drive, & too check to see if their was a possibility that through out all the parts & peices that I've managed to aquior for laptops/notebooks/etc. I was hopping and preying that I would get lucky enough to replace the battery cord, if not the battery itself. Even after taping the loose peices down so that I could turn and move the botton around to unscrew, and view what I was going to be removing to replace back together. I had some parts DROP OUT! I cannot find where they could/would possibly go; the one part bothering me most, is the FUSE; why, and ''WHERE'' could this possibly go??? I also have Older PCs too which I am ''playing'' with,it would be nice to know what parts I'm looking at, & where they go; Not too mention some sort/kind of discription! Tech Spec's, Map/ Manual...??? Please Help!

I'd like you to take a deep breath, and relax. Everything is going to be alright. You're in my world now, and this is old hat.

First of all I would like to give you a link to the Service Manual for your laptop. (It's free from HP Support. {HP bought out Compaq a long time ago)

HP Support > Compaq Presario 1900XL-1 > Manuals,

Scroll down to -
Model XL1-XL165 - Maintenance & Service Guide Presario 1900 Series,
and Left-click on it.

[This Service Manual encompasses the Presario 1900XL series, from the XL-1 to the XL-165]

This is a PDF file. The computer you are using now has Adobe Reader on it, which uses PDF files.
(I would advise at least having Adobe Reader 8, but the new 9 version is the best. You can download for free from Adobe)

There is a way to save this file to your computer.

This way you can burn the Service Manual to a CD disk, and remove it from your computer to give your harddrive more space.
If you are not aware of how to do this, I will be glad to guide you.

You may be aware of the following, but I feel obliged to detail it.
Before taking any computer apart, (Desktop or Laptop), you should follow Anti-Static Precautions.

I use a cheap ESD wrist strap, and connect the alligator clip to the metal frame, of an empty desktop computer's case.
This is an example of an ESD wrist strap,

I would use a multi-compartment container, to put the various screws in.
There are Many screws, and many of them look alike, but are not.
The compartments should be labeled for where the screws came from.
You can use a clean egg carton in a pinch.

I would suggest now that you disassemble the entire laptop, except for the LCD Display.
If there is just one screw laying against a circuit trace on the motherboard, or a solder joint, it can cause a direct short.
(Short circuit = fry out)

Shot my mouth off apparently, as I'm not aware of a fuse for this model, and the Service Manual shows nothing.
I would check the Converter Board, (Page 62)

The Converter Board is where the AC adapter (Charger) plugs in.

Now, let's talk about those older PC's.

Compaq presario v6000 computer does not detect hard drive storage

The hard disk may be faulty or it just needs reseating to make proper connection.
Reseat the hard drive and boot up your laptop. If it does not boot up then go into the BIOS configuration to see if the BIOS detects the hard drive.
If the BIOS deos not detect the hard drive then most likely it is faulty. In this case to get your laptop working again, replace the hard drive and install Windows on the new hard drive plus the Presario's device drivers and your programs.

My compaq presario c700 will not boot and it's saying that there is no bootable device, insert boot disk and press any key, however, i do not have a boot disk

Your Compaq did not detect the hard disk, that is why it is asking for a bootable device such as a boot floppy disk.
Check the BIOS configuration to see if the hard disk is detected, if not then re-seat the hard drive and boot up the Compaq again.
If it still does not boot up, then the hard disk is probably faulty.
To get the Compaq operating again, replace the faulty, install Windows operating system on the new hard drive, plus the Compaq's device drivers and your programs.

I have a Compaq Presario 2715US. Started having

The problem maybe a loose electrical connection with the RAM modules and hard disk. Re-seat the RAM modules and the hard disk.
If the problem persists then the hard disk maybe faulty.
To test the hard disk, remove the hard disk and connect it to an USB hard drive adapter and connect it to a working computer's USB port. If this computer has trouble seeing it as an external hard drive and unable to open the folders and files then the hard disk is faulty.
Then the hard disk needs to be replaced in the Compaq and Windows XP needs to installed on the new hard drive and the device drivers and programs.
