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 ...

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.

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

Thanks. smile

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--

It CAN be done; good luck!

Help!

Hit a deadend with removing the motherboard. Guess I'll try and read the manual.

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 PC card reader.

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...

Confounded.

I've read the manual. I've read the posts. I've removed what I'm supposed to remove (I'm pretty sure). And still the MB won't "just lift out."

The biggest resistence is up near the heatsink and the two adjacement I/O. Seems firmly wedged there.

Get it done by a computer tech then you have a warranty if it is stuffed.

Take a pic and post/link it. Then maybe one of us can pinpoint it for you.

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.

Got the board out -- with the help of a computer repair guy (I'd removed everything correctly, I just didn't know how to tug the board loose).

A small piece of plastic came off the power connector, so I guess I need a new one.

Is eBay the best source?

It was for me. Less than $6 shipped to my door in two-three days. Search eBay for compaq presario 2100 jack should get it. The vendor I used is also selling lots of 10 jacks for 22.99 buy-it-now instead of 2.99 (so obviously don't choose that one unless you have 9 more laptops to fix...). You may find one for less, and if you can and they can get it to you within two days go for it. Otherwise, I'd go eBay.

ps, match the picture on eBay with the jack on your board.[/i]

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 smile
