HP DV1000 stopped turning on...

Ok, so i read and read about this notebook, and how it is notorious for this. one day in class my notebook just turns off. It will not come back on at all. not with a full battery and not with ac. so i get back to my room and i plug it in, it powers on for maybe 5 seconds, then turns off.

I ordered a new dc connector and soldered it in Very cleanly. And i still get the same problem. So i go buy a targus power adapter... no dice again.

So i read on here one guy just loosened his lcd screws and it somehow put pressure on the power area and his boots fine. Well mine will actually boot to windows, but only after i unplug and plug the power in like 10 times. it will run for various ammounts of time, usually 5-10 min. it will not run off either of my full batteries.

So my big question. Does anyone know a fix for this yet? i mean so many people get this, but has someone actually tried to fix, or what? I dont want to just ditch it because i need it for my classes.

If anyone knows how, i can do the work no problem, just need to know what to do. and im in school and broke as most people.

So any ideas or fixes will be appreciated. Thank you.

 

no one has any suggestions?

 

Seems to me a bad diode, or condensor in you power supply mainboard area.Or you burn some transistor or IC in this area. That's definitively a electronics technician job.
Better bring it to a qualifier technician.

 

Thank you very much for the info. I took it somewhere and they told me it was going to be about a $200 job, so i think ill try to do something myself. i mean i dont really have anything to lose.

 

Well, you can loose your laptop
hehe

 

It sounds to me like the power supply on the laptop is broken. I ad a similar problem with my old dv6000 but it was still under warranty. I don't know exactly on whether or not the power supply is on the motherboard or if it is separate. Search the internet for a manual on all the parts for your laptop and if its separate maybe you can find one somewhere on the internet, maybe ebay. If the battery is full and even plugging in the AC adapter doesn't work all the time then my guess would definitely be the power supply.

 

I've been having the same problem with my hp dv1000 series. Perhaps collective knowledge can help come up with a solution that doesn't involve spending a few hundred dollars more on an already large purchase.

I've had mine for over two years, so warranty is out the window as far as I know. To answer an earlier post, the power supply is essentially not within the computer, but in the little box attached midway along the power cord. Laptop just has a DC connector to help itself to the output. Another forum noted getting a new adapter did nothing, and considering it doesn't turn on with battery power this makes sense. It also eliminates the DC connector as the problem.

a couple common answers that are not the problem:

Power supply - for reasons noted above, but I will probably do more testing anyway

Overheating - Cleaning out the entire fan system (which was not that dirty), plus applying thermal paste between CPU/Heatsink did nothing. Actually, if you aren't doing anything intensive this laptop will run decently with no CPU fan.


Here are things I've noticed in the couple of months I've been dealing with this.
-taking it apart all the way until you have just CPU/mem/mobo and putting back together seems to many times magically resuscitate it, but not always.
-putting the screws on very loosely when reconstructing, and with as few as possible, seems to make it more resistant to this behavior.
-when it shuts off, it is often during a twisting or jostling motion.
-sometimes after turning off, pushing the power button will cause it to turn on, but it seems very weak, then go back off after a few seconds.
-once it was down to the near bare min, LCD, mobo/cpu/ram, and would post (attempt to start up), and stayed on. I then turned it off and put it together the rest of the way. It wouldn't turn on. Took it apart to same state and it wouldn't turn on again.
-There will be times it will not turn on for days, then times it will act like normal for days even through very heavy use.

Hopefully this extra information will help someone come up with something that might help fix this. A special thanks to the first to write "you need a new mobo".

 

This is the first I heard of the problem. You should have called HP before soldering it

 

pls try the following to see if it works:

Solution: Power Drain
----------------------------------

1. Make sure that pc in OFF and then disconnect the Power cable from Wall oulet
2. And then try to remove the Battery from Pc, then let the Notebook idle for 1 minute.
3. Then make sure that there is no power and battery, then try to Press and hold Power button of PC for 30 seconds, and then release power Buttsn of Pc after 30 seconds. This should release the Static Power that is located in PC
4. Then reconnect the Battery and then powerr cable, then try to power ON PC, and check the issue.

I hope that this should start the PC.
