Question about HP Pavilion dv1000 Notebook

Random restarts caused by static?

I have 3 year old DV1040us that restarts all the time as if it was "zapped" by static. It just blacks out, shuts down, and usually restarts. Sometimes it gets hung up when it tries to restart. It seems especially vulnerable near the front left of the machine, where one of the speakers is located. Most of the time, I do not even have to touch the machine to get this effect. I know that I should avoid static discharge situations and I do. I have another laptop that never does this in the same room. Does this indicate that something is not well grounded inside the machine? Please help as I am so tired of the repeated restarts and cannot imagine they are good for the components of the machine.

    Apparently none of you are getting what is happening. It happens when I TOUCH the machine or get near to touching the machine. It seems to be unbelievably sensitive to STATIC, thus the subject. It is not heat related as it can happen when I first start up or hours later. It is not power adapter or power surge related as it happens on battery power just as often as when it is plugged in. Can we try to look at this problem again?

  • Hampel Nov 30, 2007

    Hmm, your post makes the most sense to me. So, how would I go about figuring out where this loose connection is? Will it be as easy as opening it up and following the power leads? Do you have a link to instructions that might help guide me?

    the DV1000 series has a history of problems with the motherboard .
    cpu,& cpu fan problems check the cpu fan for operation and dust lint
    buildup first before getting into circuit stuff get back to me if that is
    not the problem

I would suspect that it may be a faulty power supply or loose connection in the power cable itself. Try the other laptop power supply to see if it works. A sudden surge of electricity could also cause shutdown. Your other laptop may not be as sensitive to that. You should run a voltage regulator or surge protector just to be sure. One thing that comes to mind is a faulty memory stick. If you have two, try removing one at a time and replacing it with the other so that you always have one installed. That will eliminate the memory possibility. Sometimes you may have a build up of dust inside causing it to overheat fast. You can take a can of compressed air and blow the dust out. Since there are a few possibilities, try one at a time and one is bound to work. If after trying everything and still does not work, please tell me so that I can look into it further. Also post any error messages or beeps if any. Good Luck!

    I would start with replacing the power cord. There should be a match at your local computer store.

This seems to indicate a loose connection in the power supply. It's almost like power is taken away when you move something or touch a part of this computer. If it is more prominate in the speaker area, 9 times out of 10 that's probably where you need to look first. If you are running A/C power with batt. then it is up the line past the batt. point, because think if it's the a/c that is loose then the batt should catch it and it will not go off. But if you have a charged battery then the problem lies past all of this and needs to be soldered back.

    If you have determined where it most likely to restart by your touch. I would open up computer and look closely in that area at both side of board. You are looking for loose connection or loose wires. Cant tell you just where to look but pay close attention to that area.

Yeah I have an idea... It is likely static electric discharge. At this time of the year we get zapped touching metal things and it also drives electronics nuts... You don't even have to feel it to get zapped.

Try using in your bare feet and see if it fusses... We had a lady vocalist wearing those ugg boots and caused static pops in her microphone... anyway try the test and if it fixes the problem, then look up Staticide spray... You can get it at Amazon.com for example... spray floor in the area you are playing on to kill the static.

The only other thing is to check if wiggling the power input plug causes the problem. Those plugs are notorious for poor connections when they wear.

Compaq Presario Laptop half screen issue


no photos of the screen presented.

i guess 10 years old
2007
so one side is dead, black screen right?
and if you shine flash light on the black side, is there data there or not?????????????????
the v3000 is a CCLF back lamps (edge)
and last 20,000 hours max, (very very short life)
so when one side fails. it goes black
the bulb does or its inverter, supply does.
all do this everyone,
all go dim
then blink
then die, or are random starting.
just like a florecent light in say your garage, same deal. same gas tube.

use the flash light, see its not really BLANK IS IT
only the black lamp quit.
endless post here on topic,


in the year 2010 most of these ended and are now all LED

Hi, I have a DS Lite 2 years old and I noticed that in several games it´s turning off suddently while the game is running. Restarting, the game starts from the beggining.Sometimes the problem appears...


If you have dropped or bumped the ds lite hard against something then it's possible the black coil near the power switch is loose. This can cause it randomly shut off. The coils is the round topped black thing with 100 printed on it. There are several on the motherboard but you're looking for the one closest to the power switch. Just heat up the solder on both sides of the coil and it should reseat it.

Static cling with 3 quarter inch tape


Ngotsa, Static is NOT the reason for your fuzzy audio. Old tapes tend to deteriorate because of 1.) the way they were stored (damp, humid, and extremes in temperature), or in, or near an electric field (motor, refrigerator, TV) 2.) the lubrication (which is on all tapes) has evaporated - making good tape to head contact impossible) or 3.) the oxide (the actually tape coating) had deteriorated. As far as the Black Backing, the black backing on your newer tapes IS there to prevent static, but mainly for static build-uop during high speed rewind; if it wasn''t there, you'd actually see sparks, and you'd ocassional zaps in the sound (not overall fuzziness).

Sounds like your mother board is fried, when you change out a battery sometimes static electricity builds up on your finger tips and zap and in most cases you wont notice it, it only takes a little bit to fry a mother board.
