 |
|
The 'power connector' of my laptop (Compaq Presario 2100US) is broken
off inside the case. The male jack that you plug the power supply into
in the back of the machine is now inside the machine broken off the
motherboard. So there is not way to recharge the battery or get any
kind of power. I was talking one of my harware buddies and he told me
about a bunch of options:
- buy another power connector, take the laptop apart, unsolder the
broken connector from the motherboard, solder the new connector onto
the motherboard, then put the laptop back together.
- buy a new motherboard. Take the laptop apart, replace the
motherboard, then figure out to upgrade the new bios with all the
serial number information that is in the old bios.
- take it back to local computer store chain I bought it at to be
repaired.
- send it to HP/Compaq to be repaired.
- or cheat and buy a port replicator/docking station and don't bother
fixing the broken connector.
Can you think of any more options or reccomend which of the options
outlined looks good to you. |

This first suggestion would be my top choice (least expense if all goes
well), but it's not for everyone. The question is who should do the
work, which should be someone already comfortable (and successful) with
electronic equipment, and who is better known for soldering and
tweezers than hammer-and-tongs! Fully disassembling one's laptop is
definitely a heart-in-the-throat technical adventure, and should
probably not be one's very first... but it's a possibility.

It probably doesn't call for a new motherboard, so I'd try to avoid
that expense. Last choice.

A local service place should at least be able to give you an accurate
estimate on the repair beforehand, based on the assumption that the
motherboard itself is undamaged (which is probably the case). It'll
be 90% assembly/disassembly work, so they should already know how long
it takes them. Ask around a bit in addition to the store, who may have
to "send it out" and charge you for an estimate that another place may
know from prior experience when asked directly.

|
Factory service is a possibility, but they're more likely to quote
replacing the motherboard as a matter of policy rather than dealing
with the uncertainties of component-level repair, however simple it may
be. If shipping expenses are involved this is another minus, but I'd
still price them; no doubt they can just "look it up".

This is a clever alternative I hadn't thought of. You'd have to
decide on the expense versus nuisance value of having something that
large serve as your charger/supply! If you'd kind of like a dock
anyway, at least you'd get something tangible for your expense. I see
this as a creative second choice. HOWEVER, if the battery jack has come
off the board entirely (take a peek through the hole), you should
definitely pursue repair instead. Loose parts seem to eventually land
in places where they cause the maximum possible damage, and then you'd
have a dock for a smoked laptop. (Perhaps you could disassemble it
enough to retrive the loose jack?)

I'd say you got a good list of options. It really comes down to
expense. How much to spend? How much to risk? If you elect to try it
yourself in some way (perhaps with the assistance of your hardware
guy?), I see that the Compaq website has a downloadable "Maintenance
and Service Guide" manual that has good disassembly instructions for
your model. I took this approach successfully myself, but my Compaq is
a lot older. Good luck! |

I got a Service Manual and have the laptop apart and removed the broken
part. I even have a photo of the broken part but no part number to
search on. Does anyone know where I can find an 'AC Adapter Jack' (aka.
Power Supply Jack) for a Compaq Presario 2100US, US Product# DB954A, HP
S# CN30221049, 266MHz DDR SDRAM. Thanx in advance. |

Wow -- you're clearly determined! To the extent that I helped get you
into this, let's see if I can help you get through it successfully.
The most fertile place for these parts appears to be on Ebay. A search
there for "Compaq 2100 power jack" (minus the quotes) turned up a
surprising number of sources. It looks like 6 or 7 dollars will get one
shipped to you. I don't have a favorite vendor to recommend (my jack
was reusable), but several sellers appear to have good pictures, high
user feedback ratings, and reasonable prices. It appears that various
flavors of 2100's used slightly different jacks, so compare the
"footprints" needed closely! One vendor listed in bold print the
models (2100US for one) in which he'd used a specific jack, which was
attractive. Take a look.
As for installation itself: One of the problems is that the jack is
mostly retained by the solder connections themselves. Solder is a
comparatively soft metal compound, and eventually the mechanical
fatigue from plug stresses causes the solder connections to fracture.
Mine apparently had a dab of adhesive applied under the jack when it
was originally installed, but it had never adhered to the PC board. (I
believe this was due to the flux and solder-mask material on the
board.) Before mounting and soldering the jack back in place, I used a
hobby knife (or scalpel, razor blade, etc.) to scrape clean the
non-electrical area right under the jack so that the fiberglass was
more directly exposed... no gouging, just roughed up a bit and without
the sheen that was present on the surface before. I cleaned the area
with alcohol also. (Obviously, if your board has little circuit traces
running right there, don't scrape; but it would be unusual for them
to be found there.) I used a dab of 10-minute epoxy under the jack to
help retain it, which still seems to be working. (I don't recommend
"super glue" here, as it is too hard to keep it only where you want
it, and it doesn't "fill" as well.)
Proceed carefully, don't skip any screws during reassembly, and you
will succeed. Good luck (and post how it went)! |

Help me guys I have this exact problem too and can not for the life of me get the case completely apart. 
I have removed all of the externally visible screws including the ones under the little rubber caps and there still seems to be something holding the top and bottom together (it seems somewhere near the center of the keyboard.
Can someone send/post some pictures or get me a copy of "the manual"
Thanks a bunch! |

Try here. It's a link to the Maintenance & Service Guide to one of the
Presario 2100 models:

I had the same problem. I tried to open up the laptop without removing the keyboard first. There are three screws under it that need to be removed before the case will come completely apart.
First remove the two screws that go into the hinge area from the back of the laptop. Then use a small flat screwdriver to remove the plate above the keyboard (I went from right side to left - carefully). Four screws will be revealed to remove the keyboard. Remove them, tilt KB forward and remove cable from MB. Remove three screws and separate case (assuming you already removed the scads of other screws from the bottom and back of case), being carefull to remove interconnect cables as you separate.
Good luck...SG257 |

Hi
I have the same problem but with an Presario R3240US.
The problem is that i can't take it appart - I got to the step where i remove the fans and on the back side, but i can't figure out how to remove the mainboard - its not pissible to remove the keyboard...
Thanks |

Man you people need to look harder.. These are all different and I'll spend 6 days explaining how to's on disassembly and the reverse process especially if something goes awry in the process. Just call if you want to try it yourself and it will be easier to explain this way. Not to be A stickler but the R-3k series is a bear to do, The 2100? get the rear panel of behind the keyboard off first and the rest is self explanitory.. Good luck all..

Typically, one would remove the keyboard earlier in the process. Is the
step you are referring to from the Compaq service literature? If not,
take a look at-
http://h10032.www1.hp.com/ctg/Manual/c00212209.pdf
It's tough to find (or remember!) all of the screws here and there
without a map of some kind. (Thus, the apparent typo in you messge on
what's "possible" is more likely a Freudean slip... but I agree with
you!) I'm not familiar with your model so I can't offer any hot
"tips" other that to look at section 5.10 of the manual for some
insight. It says it's for the "R3000 Notebook PC Series", so
that's what I'd look at myself. Good luck! |

| I have a Presario 2500 w/ this exact problem... It's totally apart on my Pool Table and waiting for the $3 part off of ebay to come in the mail now. I used a Radio Shack solder gun @ 30 amps to remove the old power jack which was pretty easy... now if I can just remember how to put the thing back together after I get the part. |

30 amps! It sure sounds like a lot, but I can understand it. When I removed my connector (from a 2100) in order to replace it it was a real pain to remove. It almost seemed to not want to draw in any heat into the solder lug, as if I blew a breaker on the soldering iron. I was getting a bit worried about damaging some of the small components near the power connector due to overheating, but I finally got the old connector off, the holes in the MB cleared and the new connector on. Works like a champ now...
Good luck with yours...
