From our observation (we may be wrong) pressing the mainboard in the place to the right from right-bottom corner of touchpad caused it to restore from "frozen: state. It seems to be something with MainController which is nearby of point where we pressed motherboard. Finally we took a piece of paper, wrapped it (to create stiff cube) and put between mainboard and notebook cover (in the place where we pressed notebook). It helped, since for 2 weeks laptop didn't freeze at all. I was using it a lot and I suppose our cube from paper might be loosen now. It freezes again, but not as often as it used to. I live in Poland, my warranty has expired, I don't have a chance to send my laptop directly to USA. In my country HP doesn't not support Pavilion series. I was thinking about buying new mainboard but it is quite expensive. I can still try to sell my broken laptop and get at least some cash for it. What would you recommend me?

there is a flaw in the design of the dv4000. even with a new board, you may encounter these problems down the road again. there is a way to repair the board where this will never happen again. i have done this repair over 100 times and not once has one ever came back for the same problem.

i should contact HP because this is a really common with these units

You said it's "due to cold solder" and now you say it's not cold solder. I don't think you should lead people on if you don't know the repair.

Thank you fixerupper for your last post. I took into consideration what you wrote about tower separator underneath mainboard in the right bottom part of mainboard. I wonder, since I did something similar but not under but above mainboard. It worked for some time, but now it works even worse
Shouldn't HP admit that they sold a series of "broken" mainboards and try to replace them. I don't have warranty but it makes me angry...

there is a ball on the bottom of a certain component that needs to have a wire run to the end of the trace to repair it. call it what you will i really dont care, its a flaw in the design of the logic board.
the chip can get reheated and work but after using the system for some time, it will happen again. so its not technically cold solder like you get from a dc.

nice first post by the way

I will do my best to repair my notebook, but could you give me more details in description? In which part of mainboard should I look for "that" component? I hope I will find end of it's trace ...

I am having the same problem with my dv4000. I temporarily fixed it by adding some feet to the front right and front middle of the laptop so the left edge hangs in the air, putting pressure on the contact.
I talked extensively with HP Support, and even though I told them what the problem was, they still had my jump through hoops with trouble shooting. I finally made of list of all the troubleshooting steps I made, and finally got someone to admit is was a hardware problem. But they will not fix it without charging because the warranty is out of date. This is a replacement board that I'm having trouble with.
Initially, the usb mouse would freeze occasionally, and I just thought it was the mouse drivers. It wasn't until I realized the DVD drive wouldn't play dvd's, and tech support had me remove the ide drives that the problem got really bad. I wish I had taken note of the mouse freezing, because it was still under warranty at that time.
I suppose that there won't be any way HP will admit that there is a problem with some of these board, will there?

I want to share an opinion with you here. Looks to me like you're enjoying yourself, taunting folks who are looking for help. If you know how to fix the problem but don't wish to share the solution, why bother to post?

I'm not sure you're breaking any forum rules, but these sorts of responses can only serve to irritate people and certainly don't serve a useful purpose, IMO.

So tell me this skippy - why are you so afraid to disclose this 'private' procedure if none of us 'average' users has the facilities to do the repair? Obviously nobody here can do this master work like you can, so why not give these people a chance to try? Don't even think you can start soliciting these 'board repairs' here on NBF. This is not the yellow pages, and its certainly not the place to 'pimp' your business. Honestly, I feel that if you don't have anything to contribute to this thread you can feel free to take your unnecessary comments elsewhere. If the people having troubles with their boards wanted to have them repaired by somebody else, its logical that they would trust their machine to a licensed HP repair facility rather than some random message board member. They come here trying to find a way to use their own technical skills to make a repair to their own machine. Please, do not use this thread as a place to troll and get others riled up because 'you know something they don't know...'

Thanks and have a lovely day.

Hello... Good Reply.

I am an engineer by profession, but I do not know EVERYTHING. Try to help others when you can. It does not bring you harm. You might learn a thing or two.

If you are so smart, then what are you scared of. We cannot steal your business. The cat taught the lion to kill, but not to climb trees!

first of all who is "pimpin" a business? i do work on the side to make extra cash. is there anything wrong with that? i dont go around posting in threads for people to message me to get extra work for myself. people message me, there is a difference right? i would prefer for people to go to a local business and have their notebook fixxed. id rather have the person have a face to face relationship with the tech repairing their unit.

who is trolling this thread? it is not me. look at all the other threads that ive posted in, i try to help people without having to send their laptops anywhere. this particular system has a design flaw in it. ive seen hundreds of these units and it happens all the time. many people can not prevent putting their wrists down on the palm rest while typing. even if the board is replaced and this mod is not done, then it will happen again.

does KFC give away their secret recipe?

So, why are you posting here if you're not trolling? You're not helping anyone in this thread whether or not you do so elsewhere.

im only replying to what he/she said. he quoting me so i quoted with a response. i am not trying to cause any issues.

trolling is not what i am doing. i am part of many internet message forums and this is not trolling. trolls are people who come on boards and flame people and make tons of stupid threads.

i wasnt the one doing the name calling either. who was the one calling me skippy?

Trolling is when a person posts as an effort to try to stir up problems whether by flaming, name-calling, or taunting people by claiming to have info which will solve notebook issues that he will not share.

I've read some of your posts in other threads - they show that you can be helpful. My suggestion is to stay in those threads where your posts are appreciated.

Multiple HP Pavilion dv4000 problems - seeking a solution

From my experience and after reading the posts on this site about the dv4000's on this site I would conclude that the design is flawed, most probably in more than one way. A co-worker and I have had the same experience with frequent system freezes, keyboard and mouse pad lock-up, usb ports not working, occasionally not booting. One day it works, the next it doesn't. I sent mine to UCR in Dayton OH for a repair estimate (it is a year out of warranty). They confirmed the problem, but their resolution suggestion was to replace everyting: motherboard, usbboard, dvd player, keyboard, touchpad - everyting but the screen and case. To their credit they did not recommend that I proceed with the repair.

HP should own to this problem, but they won't, of course. In the meanwhile, those of us with these units are looking for a way to recover/repair the systems that we paid a lot of money for. If it is under warranty, they will keep on swapping out mother-boards until the problem dissappears, the warranty expires or the owner gives up, whichever comes first. A repair bulletin describing the problem(s) and a fix would be nice.

If anyone has a real solution, or really understands the problem, I would appreciate hearing from you. Thanks in advance.

Hello people,

I got rid of mine and also a free out-of-warranty repair in the UAE. Sweet talk does it all!

Just bought a Toshiba Satellite. Sweetness. Cheaper and more stable. I am loving it.

Bye.

FCUK HP. No more of that expensive garbage for me. The Toshiba was about 2000 AED Cheaper than the
HP that cost me 4750 AED here (Local currency).
