Presario 2100 broken power connector
 

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.

- 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.

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

- take it back to local computer store chain I bought it at to be
repaired.

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.

- send it to HP/Compaq to be repaired.

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".

- or cheat and buy a port replicator/docking station and don't bother
fixing the broken connector.

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?)

Can you think of any more options or reccomend which of the options
outlined looks good to you.

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!

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)!

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

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

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.

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...

FWIW I'm working on the same problem with a 2100 ... still trying to
find the non-obvious screws on the case, so this thread has been very
helpful.

I'm guessing this would be a $200US-ish job at a local computer shop,
so the effort is worth the money ... assuming I don't eff the job up
and kill the notebook, which is very easy to imagine doing.

Talking of murder, who the hell's responsible for this delightful
piece of hardware design that has so many of us tearing our hair out
and wasting time and money? As far as I'm concerned, it has seriously
interrupted my work.

With so many people experiencing the same problem, is there grounds
for a class action lawsuit against HP?

Meanwhile, back at the disemboweling, where did I put all those screws
...

Presario 2100 broken power connector
 

On a practical note, will it be possible to re-solder the existing
power pin, which is wobbly but not broken off, once I get the box
open? Or will I almost certainly need to use a new one?

Thank you.

Presario 2100 broken power connector
 

Obviously, YMMV, but in my 2100 one of the three solder lugs had
actually broke. The price for the part on eBay was dirt cheap, quick
to arrive, and worth the comfort of a solid repair.

In my case the laptop wouldn't even run, and once the repair was
effected, the unit booted up under battery power (must have been a
short?). Whew!

Good luck with those screws...let us know if you still need help
finding them...I needed it.

So I have the laptop open. The only piece I'm not sure about in the
disassembly is a small black lead going from the motherboard to
display or somewhere. Should this be disconnected? I can't see how.

As regards the power connector, there it sits black and wobbly -- and
very small and cramped. What do I do now? Can I solder it so it
doesn't wobble? Do I remove it (how?) and replace it?

Help :paranoid:

If the connector itself is intact, it might just need to be resoldered
to the circuit board. However, if there is ANY damage or shortfall
whatsoever (loose center contact pin, cracked connector body, etc.) you
absolutely should replace it. It makes no sense to go through this much
grief and not make the very best repair possible. Soldering the
connector in place will require access to the underside of the board,
which generally means having to remove everything from the case in
order to extract the motherboard. The appropriate service literature
for your model should be downloaded and examined if at all available.
While not always perfect, it's a really big help. There appears to be
one for the 2100, depending on the specific model. See the
"Support" section for your model, select "Manuals" and look for
the Compaq "Maintenance and Service Guide". If I'm right, you can
just download--

I've removed all visible screws, including the six on the I/O ports.
Most of the MB lifts up but there's resistence on the side with the

Should I remove the PC card reader? Can't see how, even though I've
removed all visible screws.I did my 2100US board last weekend so here
is what my memory serves...Remove:

six "screws" for the I/O ports on the back of the laptop (you've got
it already)

two long screws from the PCMCIA card slots.

two screws that hold the hard drive "cage"

two (?) screws that hold a metal "shield," just left of the hard
drive

two (?) screws under the shield you just removed

one (?) close to the power connector

There were 1-3 others I believe, but they were obvious.

One last one...there are three screws holding down the
heatsink/heatblock on the cpu, you need to loosen (not remove) the
ONE towards the back of the laptop. Loosening this screw removes
pressure on the metal frame at the back of the laptop. JUST DON'T
Forget to retighten it when reassembling the unit!

The only other "hang-up" I had was the audio jacks where they
penetrate through the case. GENTLE prying or jiggling the MB shoud
allow these to clear. Otherwise the MB should just lift out without
any effort. So if it is still stuck, there is still a screw to
go...

It should just tilt out, pivoting along the back edge a bit, then lift
out completely. Until it does this easily, something is still
remaining that must be removed.

W00t! Thanks for the luck, as I got mine working too, I had a 2500
though. So here's a note to all other people w/ this problem:

Your laptop will be 100% dismantled for this repair. As long as
you're a confident person, all you'll need to fix is the $5 part from
EBAY, a soldering iron and solder from Radio Shack for $8, a small
phillips screwdriver and some needle nose pliers.

Take it all apart, you'll have the motherboard in your hand as you'll
need to un-solder the from the bottom of it. Heat up the 3 pieces
and pry that pos off. Place new one on, apply a 3 beads of solder in
the correct places. Put it back together and turn it on... took me 90
mins and I have no soldering experience whatsoever and had to solder
the fan jack on my mobo that I snapped off by accident too. One more
thing is I re-greased my processor w/ Artic Silver while it was apart
and it runs about 5 degrees cooler now :)

Well, I got a new power connector ... but now I've got a new problem:
in removing the old one, one of the pins broke off. So the old
connector is gone but a piece of a pin is left in one of the holes
... soldered.

There's no end to grab. But even if I could, there's the solder. How
do you melt the solder without burning the board? Any suggestions?

Thanks.

Presario 2100 broken power connector
 

Wow, that's a bummer. I'm not an instrument tech by trade, just a
hobbiest/hack. But the things that come to mind are to either drill
it out with a TINY drill (dremel?) or to heat up the joint in the
board (may have to apply a bit of solder to get the heat to conduct
into the board) and try to shove a more intact piece of one of the
remaining pins back through, pushing the broken one out (or use a
mini screwdriver in lieu of one of the pins, they will possibly just
bend).

Either way, you could probably use an extra set of hands. I did with
mine, one of my pins were really in the board and I needed someone
else to pull on the tab while I heated and held the board.

Definitely get other advice than mine, from someone who has
experienced this problem in real life. And good luck man!

Presario 2100 broken power connector
 

The problem is irritating, but not insurmountable. The trick is to have
at hand a technique that will get the job done without having to heat
the solder pad for an excessive amount of time. I'll propose two
methods; a combination of the two will probably be the most effective.
If you can get help, so much the better, but here's what I'd do if
I could be the

First off, you need to be using a proper soldering iron. A small one
(say 15 watts) that would be appropriate for the smaller circuitry
elsewhere would take to long to heat this larger joint; on the other
hand, too large an iron could quickly overheat the board (as you have
been concerned) and cause the soldering pads to lift right off the
board! Something around 30 or 40 watts should be about right. (For
example, a 140-watt soldering gun would be out of the question!)

Since there's nothing to grab, I'd heat the joint and poke the
broken stub out with something. The "something" can be anything
that will itself fit thru the slot without either catching on fire or
becoming soldered into the slot itself. I've often used the
appropriate diameter of one of my cheap set of jeweler's
screwdrivers, or even the "back" end of a small drill bit. You can
pick the right tool by testing it on one of the already-open slots. (It
needs to be something fairly small so that it will not "soak up"
too much heat and inhibit the process.) You'll have to heat and poke
simultaneously by applying the soldering iron tip to the solder at the
side of the slot, so you can run your "poker" thru as soon as the
solder becomes flowable. Since the broken terminal may have become a
bit club-footed on the top, I'd work and poke from the bottom side of
the board, as the terminal may not pass through going the other
direction.

The other approach is to remove nearly all the solder so that there is
little to retain the terminal stub. This could be done with a number of
solder-removal devices, but the simplest is merely a copper braid used
to wick-up molten solder. The material is laid over the solder you wish
to remove, and then the iron is applied to the braid which draws the
molten solder away by capillary action. It may take a few applications
of "fresh" sections of braid in succession to get all the solder.
The most common product variety is called "Solder-Wick". Radio
Shack stocks a product they call "desoldering braid".

Doing a bit of the solder wicking action may make the first method
above go more easily by making the stub easier to see and poke at, or
it may even be effective all by itself. Each problem is a bit
different, but it can be overcome. You're almost there! it may help
to visualize and practice (with the iron off) how you might best hold
what without burning yourself so you'll have a technique in mind once
you actually start. Good luck!

There are different type of jacks on Ebay for Compaq Presarios. Can
someone confirm if

is the right jack for a Compaq Presario 2100US? Thanks in advance.

I have another question. Do I have to have any contact with the bottom
side of the motherboard? I don't want to remove the motherboard from
the case because that will be a bit annoying. I just have to solder
the new piece from the top right?

have a 2100US and it "LOOKS" correct. Compare it with this link

which is the one I used to repair my laptop.

remove the motherboard to gain access to where you de-solder the old
jack and re-solder the new one in. You cannot do the repair from the
top, and you will be more comfortable with the actual repair with the
motherboard removed. Check out earlier posts in this thread to see
how it is done.

Hi all..

I have a compaq presario 2100 model laptop. My ac jack is found to be
the problem. As discussed, i have thought of buying a docking station
for that. But, the latop i have doesnot have the docking connector
(bottom side of the notebook).

I just see a rectangular marking on the back side. WHat should i do?

1. buy a new backside case? or
2. is it possible to just mount that docking connector to my existing
backside case

Please gimme suggestions...

Also, how much does it cost just for docking connector or new backside
case...

Bye

I don't have a 2100, but I see by looking at Compaq's
"Maintenance and Service Guide" that the docking port connector
appears "on certain models" in the series. A new lower case half
(with a cutout and cover for the port) would not help, as the needed
connector (and probable support circuitry) would undoubtedly be absent
also. The odds of adding a connector would be slim. On most systems, it
typically mounts to the motherboard itself, so adding it -- even if
possible (or available!) -- would be far more complex than replacing
the DC power connector.

I do notice that the 2100 parts list shows a "port replicator
cover", and the bottom view drawings show a rectangular cutout shown
as "port replicator connect" on the bottom near the rear of the
notebook. Is yours just an outline in the case plastic as it appears,
or is it perhaps a removable cover? Take a close look... it would be
great if it's just there waiting for you to uncover! But if it's
not... then it's not, and won't be. Good luck!

Not all of the 2100's/2500's have the full featured board design
w/docking station capabilities. On another note? Quit feeding E-bay
and go to Digi-key.com or Mouser.com for the jacks? I can get these
for a whopping 60C per and man I hate to see people getting ripped by
the E-bay scammers selling at 500% profit margins. (I know I started
there buying and selling inop laptops) If anybody needs how-to help
or info feel free to contact us also. We do these for 89.00 parts and
labor plus a whopping 14.00 for return ship if you cannot do the job.
Also good posting on the genteman offering info on the desoldering
braid and other options! (We have to tell people this every day via
phone).. But 40 watts is a min ammt need for the iron to get it to
flow w/ wick involved on the negative side for these. Good luck all.
