Hp pavilion dv3

Hi, i have an hp dv3 4101sl and yesterday i tryed to clean the fan and the dissipator sistem from the dust layer that formed during the last two years of use. After disassembling the laptop (i did that at least 100 times before, with different models of laptop and desktop) i've cleaned everything and i reassembled the laptop to check the working temperatures after this operation, the laptop turned on normally but after 2 minutes it switched off without any "beep" or warning message. After that the laptop completely died. the power button has no more light at all when i try to switch on the laptop, I've read about the hard reset procedure (unplug every kind of external device,unplug battery and power supply, and keep pushed the power button for 1 minute) and i've tryed to perform it as well but, even in this case, nothing happened. I've read that some times adding electroconductive thermal paste(too much) on the gpu/cpu units may cause short circuit on the motherboard but i didn't put any new thermal paste on my laptop. The only thing i can tell is that if the power plug is connected, the "power plug light" on the side of the laptop switch on normally but when i try to push the power button the light switch off immediately. Is the mother board shortened?is there something i can do to save my laptop?

    with power plug led i was meaning the led that is directly on the laptop, non the led that is in the power supply(mine doesn't even had one on it).

    ok, usually what's the way to test the working condition of a cpu?Is it possible to do that only with a working mobo or is it possible to perform this test even with other instruments?

    ok, meanwhile i've found a mobo for my laptop for 60 dollars and probably i'll buy it hoping it will solve my problems.Anyway thanks a lot for your time and for your answers!

It looks like there is a short somewhere inside the laptop. Could be the mobo, or just about anything else connected to the power supply.
Try disconnecting the power connector on the mobo, then try plugging in the power plug and see if the light still goes out. If it does not go out, then the problem is the mobo. If not, then somewhere else. Try disconnecting the power from one component at a time to eliminate the various components. Also look for wires that are shorted together or connectors that are inserted improperly.

    hi, i've tryed almost everything, i've inspected for a long time every single cable in the motherboard,nothing seems shorted. I've even already tryed to disconnect every single components from the motherboard , in the end i had a motherboard connected only with the power button from one side and to the power plug on the other, but the result was always the same...For the light problem i had to say that i haven't any led on the power adapter itself, the led is directly on the laptop, on it's side, near the power plug hole on the laptop case.

  • budu8585
    budu8585 May 15, 2014

    but anyway now my question is: how can i recognize if the problem is involving only the motherboard or even other components?I mean : will the cpu be safe? and other components? i mean there is nothing i can do to have back my motherboard apart from purchasing another one?

  • lesB May 15, 2014

    Try removing the power plug from the mobo and see if the LED still stays off. If it does stay off, then the problem is not on the mobo.

    with power plug led i was meaning the led that is directly on the laptop, non the led that is in the power supply(mine doesn't even had one on it).

  • lesB May 16, 2014

    I get that. Still the LED is presumably indicating the presence of voltage from the charger. Try the test I suggested to narrow down the area of problem.

  • budu8585
    budu8585 May 16, 2014

    it stays off but just as it always did...without any mobo connected the power led wasn't able to switch on...

  • budu8585
    budu8585 May 16, 2014

    that's what i mean with side led...when you connect it to power supply and to the mother board it switch on correctly but when you push the power button on the mobo it switch off immediately without having signs of life from the mobo

  • budu8585
    budu8585 May 16, 2014

    without mobo attached the led do not switch on at all. My power supply work fine for shure because i've tryed it on my flatmate laptop.

  • lesB May 16, 2014

    I'm thinking the LED might be connected thru the mobo, and that's why it doesn't light with mobo disconnected.



    Looks like mobo presents a short to the power supply. You can try removing the CPU and see if the LED still goes out. If it does not still go out with the CPU removed, then the short is likely in the CPU.

  • budu8585
    budu8585 May 16, 2014

    i've already tryed, but still the same situation...i think the only thing to do is to buy a new mobo. But i'm thinking: is it possible that a short circuit able to kill the mobo happen 3 minutes after loading windows with laptop normally booted? and second question: what about the cpu?will it work on an hypotetical brand new mobo(estetically it look flawless)?

  • lesB May 17, 2014

    A short can happen at any time, it's usually a random thing. Assuming the CPU is still good, it will work with a new mobo. Without having the components right here to test I can't tell for 100% sure. But that's the likelyhood.

  • budu8585
    budu8585 May 17, 2014

    ok, is there any metod to test the cpu working conditions without a working mobo?with a multimeter or something else?

  • lesB May 17, 2014

    A CPU is a complex device and not testable at home, short of plugging it into a working mobo. There's an outside chance that the manufacturer would test it for a charge. They would plug it into a computerized tester that would run it through a battery of tests to check all the features.

  • budu8585
    budu8585 May 17, 2014

    ok, meanwhile i've found a mobo on internet for 60 dollars, i'll probably bui it hoping that it will solve my problems. Anyway thanks a lot for your time and for your answers!

Either the new power supply you purchased is not functioning correctly. But, assuming it is now that you are getting some form of power to your PC, it is very likely the motherboard. Whatever fried your old power supply (or it could have just been the power supply itself) most likely fried your motherboard in the process. Probably not the CPU since the MB can't even post.

SOURCE: won't power up

It has to do with the KT-600 series "anti burn regulator" and how it has a hard time with the XP2600 thru 3200 CPU's because they get so hot so fast... Try pressing the power on button again immediately after the long beep ends. Your computer should boot right up. Or, you can disable the ABR by removing the jumper from the pins on the motherboard. I haven't tried this because I like knowing the ABR works so good. It only takes a second or two to fry a CPU.

SOURCE: Computer will not boot up.

remove all external devices. except the memories.
turn on the PC.
it if comes on insert each of the external device one at a time, till you come across the one that is causing the problem.
if it doesn't come on, remove the memories. and swap the memories. if it still doesn't come on, remove the memories. and see if the BIOS come sup. if it doesn't, then you have motherboard problem.
go back and check all connections. make sure the connectors are in right orientation and not pins are missing.

Hp 6830s is to nois. Fan is tooloude


If the fan making a smooth spin, but the noise is too loud, then it means the fan is trying to dissipate the heat. Probably the air inlet and or the air outlet (also the fan itself) is dirty (or clogged) and you need to clean it up using a canned air.
You may need to open the case/body if the dust become a dust ball (and you need a tweezer and qtip to pickup the dust ball and clean up the fan blades).

My notebook is too hot when I play any movie and sometimes it auto turn off. My notebook is a DV3 2150us


I would try and blow out the dust from the machine, a build-up of dust can cause the laptop to overheat and that could cause the machine to shut down. Often times the fan gets caked with dust and cloth fibers from having it on your lap. If the laptop can't get enough cool air, it overheats and shuts off to protect itself from damage.
Thanks, and have a great day!If my solution helped you, please don't forget to leave positive feedback!

Honestly, try harder. If you've taken the thing apart, you're more than half way there. You probably just need to unscrew more stuff and pry more parts out.

How to Replace a HP Pavilion dv3 Fan?

1. Follow your laptop owner's manual and assembly guide carefully you can download this from HP web site as you disassemble the laptop. Touch something metal periodically to remove static charge, and work on a large table with a bright light source.

2. Turn off the laptop and unplug it. Remove the main battery, CD/DVD drive and the hard drive. The hard drive is usually located in a slot on one side of the laptop. Remove the screw that holds the cover in place, then pull out the hard drive sled.

3. Turn the laptop over and remove the screws on the bottom that hold the keyboard in place. Flip the laptop over, open it, then lift the keyboard up and out. Unplug the flexible ribbon cable that connects the keyboard to the motherboard.

4. Remove the screws that hold the keyboard bezel and palm rest in place. Carefully pry loose any plastic snaps on the sides, then lift the bezel and palm rest up and out.

5. Unplug the HP Pavilion dv3 Fan Cooling Fan. Remove the screws that hold the heat sink and fan in place, then remove the entire unit from the laptop. Remove any thermal compound residue from the bottom of the heat sink and the CPU.

6. Apply a thin layer of thermal compound on the CPU, then replace the heat sink and fan. Replace the screws, plug the HP Pavilion dv3 Fan back in, then reassemble the laptop.

7. Plug the laptop in and turn it on. After you use it for a few minutes, you should hear the new fan running and feel warm air blowing from the vent on the side of the laptop. A HP Pavilion dv3 Fan does not run continuously, so don't be concerned if the HP Pavilion dv3 Fan shuts off periodically.

HP Pavilion dv1000 heating problem during accessing internet.It works fine often when laptop is not connected to internet. Any suggestions is appreciated.


Try checking the fan, if you see dusts clear them out. If you have a USB fan, its highly recommend you use it. My Answers maybe incorrect, because I do not use heated laptops or PC Desktops.
