zx5000 power socket troubles...

Thread Starter 
This is a zx5190US, HP laptop.... I believe the power socket has given up the ghost. To get it to provide power to the laptop, you have to push on it VERY hard to get it to make contact... then it will work for a few minutes, than stop...

Figuring a bad solder joint, I opened it up (like I have done a couple of times already to resolder the socket), and checked the solder joint. It's good. I put a meter on the connections... there is continuity between the center pin and the square SMD cap right behind the jack.

I am lost now. I have to power the laptop through the expansion port (using HP's expansion port cable).

Is the jack just dead, or is there something else wrong? I think I have gotten pretty good service out of this thing, considering it is almost 3 years old. However, I cannot afford to replace this thing right now......

u r still able to charge, load via the dock, so it is pretty much that ur power jack has taken the dive.

we have enough posts in the forum to guide u through the replacement of the power jack if u r willing to take the machine apart urself

or there is plenty of techkies here that r willing to work for beer&pretzel (i mean real $)

or ur local friendly shop

cheers ...

This thing is a cakewalk to take apart... I have already resoldered the socket a couple of times.... so I thought the socket itself was bad, but I am still getting power though it...

I just hate to keep using the dock connector....

Just a suggestion in case you haven't done it already, but have you tried another A/C brick?

I'm thinking that under a load it's dropping out, OR there is a break in the connector on the brick inself.

if you have to keep having to resolder it then you are not doing a good job, no offense. after a DC port is resoldered, it should not need to be resoldered for a while.

the pin behind the dc port that goes into the logic board actually gets cracked too. its something that i found by looking at one under a microscope. it could be that your dc port has that issue.

i have some extra dc ports if you are interested in getting this problem fixxed correctly. i love beer!

Yeah, I am interested in getting a new jack for this thing.

I have two bricks, and they both do the same thing..

I'd recommend NOT using the same factory jack as these are a pile. (Weve seen hundreds of this model in the last year alone).. We us an upgraded jack and they hold up Xlnt. The hardwire Signatron jack is shit and Toshibas have bee having the same problem with their new lappys as well.

older toshibas use those.

its not just an issue with the dc connector itself, its also user error. people are not plugging in their ac adapters, ac cords correctly. if you really seen as many as you say then you would know that some become discolored in the back.

there are obviously two types of dc connectors the zx5000 series motherboards came with. the ones where the rear of the pin is exposed and the other where it is not. the one that isnt exposed is crap. i agree with that. the other ones can be repaired, i do it every day. there is no reason to LOSE money by changing it unless its the crappy dc hahaha

Dude you are full of shit! Ive replaced these too many times to know better and the factory jack is a problem. As well as the Schottkey in the supply line. HP's had nothing but issues on this baby from Imbedded controller chips to basic jack issues and go ahead and reflow/resolder the jack.. It will come back. The other jack you referred to is a Foxconn and HP's already settling out regarding this problem, 2nd jack is almost as bad as the wire is soldered into the centerpin and it gets cold joints and cracking down the road as well. = A heated up trace=Schottkey croaking=(Intel based units).. AMD hold up better because of the fact there are two schottkeys paralelled..Toshiba does use this same jack with a 4 pin shield and guess what? Same problem.. Keep plugging away there bud..

is there a reason why you are cursing at me? if you have a problem PM me. dont make yourself look ignorant.

i work on these systems all day long monday thru friday for one of the largest laptop and printer repair depots in the country. we do repairs for multiple extended warranty companies, compusa, circuit city,and best buy before they got their new geek squad city in louisville, kentucky.

if you want to try to tell me i dont know these systems then thats fine, because i know how to repair torn traces, re-ball bga chips, replace them, repair cold solder in ram sockets, replace cpu sockets; etc....

im a component level laptop technician, im not your trypical a+ geek squad furrball.

i dont care what you say, the dc can be repaired. so keep pretending it has to be replaced, because it doesnt you theif

Was not knocking you but the jacks are shit! Singatron builds a better jack and they are a hell of alot better than the hardwire jacks that are breaking down internally inside the positive pin. Do a cross section on one as well as check under your scope and you will see what I'm talking about. I'm not here to slam anyone but we do the same repairs and I really dont care who you work for. The fact is if you can get a better component to replace the factory one then its a no brainer in my opinion. If you want the part number for the better jack I can give it to you and if you disagree its not a better design then so be it. HP's actually involved in litigation over the origional series jack now. If they were fine? why would they be there? Anyway Apologies if it seemed rude but your prior post seemed the same.

Also the new, Better jack is actually the same cost..So theres a dump of the old wallet for a better component.
