The airflow is completely blocked in mine, and two years ago when this happened I got so frustrated I broke the plastic backing covering the fan to clean it and replaced the fan and the back of the laptop. Now I see the actual way to clean it, thank you!!
I'm not buying another laptop unless it has a door to access the fan!
Had to put one of these bad boys back together for some kid from school. Super smart of them
All this, for a fucking fan?!?! thanks HP
Fuck designed on dv4...just to access to one fucking fan on the system
Is it this hard to access the fan on all newer laptops now, or just the HPs? This is insane; the fan should be the first thing we see when we screw the nails on the exterior.
thanks. if my hard drive had not died wen my laptop fell i wud not have searched and found such a useful video...better late than never
SUPER useful!!! I am now a follower... I just got a DV4 for free because the screen was supposedly damaged. I watched the video and disassembled the laptop only to find that the screen connector wasn't securely seated.(Which solved my issue.) However, I followed the entire video through and cleaned the fan and re-applied processor paste and now it runs like it was brand new out of the box. Once again, your video saved me sooo much time and frustration trying to take this jigsaw puzzle apart...
MUCHAS GRACIAS!! este video me sirvio muchisimo para destapar mi portatil, llegaba hasta 100 centigrados y ahora despues de una gran limpieza llega hasta 54 o menos. es un video que nos sirve muchisimo a los que no somos tecnicos y queremos destapar nuestro portatil por primera vez.
un saludo desde colombia!!
Just finished cleaning my DV4, it works GREAT!!! The fan was DISGUSTING and dust was covering the grill so air could not get out. Extremely quite and runs like a dream! Thanks for the video, very helpful!!!!!! :D
Great Video even on fast motion. I lost my dashboard light afterward, But the laptop is so much quiet now. And its been 20 min since cleaning, TEMP is holding nicely. Thank you.
I love how it looks like you're throwing all the parts across the room
omg your a life saver! i opened my laptop for the first time by just watching this video and it went great! i ended up having two dust strips like the one in the video clogging up my fan. i used silver arctic 5 for the heat sink and now my portable cooler is louder than my laptop :D
first time, and it was pretty easy actually. just keep track of the screws, and take ur time. Thanks!
i had a problem with my fan being seriously loud all the time and almost always on, i tried to take it apart but found it way too difficult and didnt want to damage anything (i have little experience with dissambling computers) so i put it all back. I then found the problem getting worse so i took the handheld end of a vacuum cleaner (the small suction part) and just put that over the fan hole in the bottom of the laptop....worked perfectly, and now the fan makes very little noise at all!
All of these issues however generally require motherboard and CPU replacements. If are unsure if the unit is POSTing, after powering on the unit, wait a few seconds and attempt to toggle the CAPSLOCK. If it responds and lights up when you press the key, the unit actually POSTing, you however have no video output. This can be confirmed by plugging up an external monitor to the VGA port. A very common issue for this model is for the LCD cable to become unplugged from the motherboard.
TYVM for this. I don't think I woulda had the nuts to do this without it! I completed the process (about 2 hours in total) and when it didn't boot I was very discouraged, but I reseated the ram chips and voila, good as new (for an HP lol). This saved me from a costly repair or from buying a new lappy.
I have only 3 screws left over (2 are the silver sort so if anyone has an idea where they go lmk). I also found the schematic plans useful (google for dv4 schematics and click to hp site).
i was wonderin wha was the most time consuming complicated warranty voiding way to break my laptop. thx for helpin me out nd wasting my time nd money
You can fix this issue by taking out the following screws:
The 4 screws under the battery, use the CD-ROM ejector tab and take out the 2 screws under, the 2 rear hinge screws on the left and right of the bay, 3 keyboard screws, one under the BIOS bay door. Now flip over the unit, removed the keyboard, and take out the 2 screws (black and silver that are on the keyboard cover/function switch cover bezel and unplug the cable. You should now see the LCD cable after removing that last bezel.
thanks for this video, it took me about two hours for the tear down and build up. i am having trouble with a guys dc plug, this kept it from being a whole weekend project.
Not being a computer savy guy. After seeing your video. I attempted and was successful. With some patience this can be done by a novice. replaced the fan works great.
Bravo, good work. I was stuck at keyboard and hinge part and now I can attack it again. Thanks.
My Gateway has a panel that covers the fan, memory components, and processor, and it is very easy to get to!
thank you so much, thanks to this video i can dissasembly my lap and clean it without any problem!
Giant thanks for uploading this video. I did a full breakdown and couldn't have done it without your video.
I liked this video, it helps me too much.
Only a thing, the keybord was not well now.
hola! pues mira yo no tuve necesidad de utilizar el alcohol porque la pasta no estaba tan seca, solo fue limpiarlo y brillarlo con un trapito, en cuanto a la pasta no pude conseguir la silver 5 aca en mi ciudad asi que compre una de esas genericas, solo preguntas por pasta termica o grasa termica para procesadores, y pues a mi me sirvio mucho porque mi compu quedo muy bien!! ya no se calienta tanto :D
Great video and great description. I have a huge home fan pointed to my laptop and it's running almost at room temperature, but it's so noisy I can't hear my own thinking. I'll take notes of this video and try cleaning it myself, if I don't come back and comment, means I f*cked it up.
Agradeço muito!! Consegui arrumar meu dv4 com sua ajuda. E valeu pela trilha sonora!!
Vary nice. It was vary helpful when i took my dv4 apart. When i placed it back to gather, it worked perfectly.
I don't know if you still care or not but I had this problem and I figured out that is was the angle of my laptop. If I started it up with the screen 90 < 0 degree angle then it turned turned on.
I got a dead hp dv4 for free, and watched this and it's now up and running .
thank you, was very useful for me too, my display quit working.. looks like it is getting power but now visuals; the data cable might be damaged or partially unplugged.. going to open her up and see what is going on..
@SlaginnMetal247 pretty much if you anti static yourself, there is nothing to worry about electronics are more resistant to damage than most people think. just do it
Another much easier alternative for this particular model is to use compressed air and a shop vac. I bought a used hp dv4 laptop on the mercari app as is for $15 because it had an overheating issue. Fixed it in literally 5 minutes. Yeah probably not the best method, but for a cheap 10 year old laptop, I didn't have much to lose.
If you get the no boot, no video with a flashing num lock and Cap Lock take out the Wifi Cards and try booting... if it comes up swap the locations and then see if if boots with that arrangement... I did that once... ;-)
one is a watch one is a wrist bracelet conected to ground to top static
Thanks a lot for this video! Took it apart and reassembled thanks to your video to clean CPU and change flex wire to the screen and works perfectly !

There is someone in my area selling one of these laptops for ONLY 170$! In the post he says it get's really hot, and it has something to do with vga. I do realize I am taking a risk here, cause it may be something much worse. I'm going to buy it and open it up and put some artic silver 5 thermal paste on the heatsinks, and clean the shit out of the vents.
The BGA contacts are broken for overheat. Disassembly (at your risk) just like the video above. Use a hot air blower over the BGA for a coupple minutes and reassembly. Take care to don't burn anything.
It may work for some days, but this machine has born condemned.
I'v seen that lint problem in many laptops... But in one laptop the owner kept using it without taking it to me or another professional. And b/c of that it damanged the GPU. So if you are noticeing high heat and turn off's like that then either do a full cleaning like this video or take it to someone. You can damager parts on the board that will make you need to buy a new board to replace the entire motherboard. I use arctic silver 5 simply b/c its a better paste. But 5 stars on this video :)..
Thanks! Now my laptop is running smooth again...
@FastVideoTech Yes, the keyboard works well, but now when I press some keys, the keyboard moves down XD.
I think the notebook's top doesn't well. But it works very well. Thank you for yor video @FastVideoTech
thanks for your video it really means to me alot , i hope u make these sort of videos of different laptop machines . Knd Regards
About to try it out, but first Imma buy the thermal past tomorrow morning.
thank you very much..this video made me open my old dv4 hp.. i did everything as you .. and now its positive. greatvideo man
@FastVideoTech Afraid of not assembling the laptop after open it, I asked an expert for doing this. He did not remove the screen as well.
Anyway, thank you for reply :)
The HP dv series laptops are a major pain to fix. Most laptops do not make you pull the whole motherboard out just to get to the common task of cleaning dust from the air exhaust port. Nice going HP. This is not a job for amateurs on these systems.
thanks I was able to re-assemble my laptop because of watching this
@w4tch4cl4wschannel You ABSOLUTELY NEED that thermal paste (zero thermal) he was talking about! That is vital that the heatsink has the best possible contact with the CPU without it you will experience overheating, among other things. It IS overheating, you don't seem like you know anything about what you are doing. Get some thermal paste and put it on or risk the life of your cpu as it may overheat too much and either go up in smoke, or just stop working.
@thegamegorilla
First thing, you are going to have to make a diagnosis of the issue during the unit's attempt to POST. Wait after powering on the unit to see if the board will generate a POST error code. This can be read by watching the CAPSLOCK and NUMLOCK LEDs:
The LED's will flash in a cycle, these are the meanings of those blinks (this is the same for all HP laptops)
One Blink is No CPU detected
Two is a corrupted BIOS
Three is Faulty RAM
Four is No GPU detected
Five is General Board Fail
Perfect manual, helped me service my dv4 flawlessly. Thanks for the upload.
If you've done this and it is still overheating, check your fan (listen) to see if its even starting up. I opened mine up just enough to see the fan and verify that it wasnt starting up even when the temp reached 75 degrees. Now, Im just waiting to get a new fan in the mail to replace it. Hopefully its just the fan that is broken and not something iwith the motherboard that is causing the fan not to start up.
hi! i really thank you for uploading this video, i opened my computer completly and without your video i done it because of you! so thanks!
make sure you connected the lcd flex cable properly
Will give you guys an example..... Was getting a bsod and hardware failures.... took my custom built dv8 to microcenter to get bench tested and they wanted to charge me 75 for diag and 460 to replace a few things(usb/audio card, wireless card, cpu fan, and keyboard).... for the 4 hrs it takes to disasseble and reassemble.... its worth the 75 for bench test and 100 in parts..... to do it yourself. Just be warned, be very careful pulling off the heat sink, they thermal paste that HP uses is crap.
Oh actually I remember now it stopped working right when I got it back from being repaired by HP through best buy Geek Squad for a totally unrelated issue. I got it back 7 weeks after I dropped it off (which also happened to put it past my 3 year extended warranty), the hinge on the screen they repaired broke a week later, the speakers an the fan stopped working around the same time. I know every is thinking "why didn't you bring it back to Best Buy" well being a college student it is nearly im
@shahzad05
1). the thermal pad is a VERY bad design for the video chip (on tail of heatpipe) and most likely it overheated quickly due to a gap. Replace with a new pad or buy a copper shim so as to make good thermal contact.
2). I believe too much thermal past was used on the cpu (should be extremely thin.
3). your video cable may not be flush with its socket.
4). I had video problems for 4 months (had to keep closing lid), fix replace inverter under base of screen (HP logo).
I totally dig the music! Who is the guitar player (pardon my ignorance)? Great video also, may just save me some money knowing where the problem lies. If not I'll just box it up with a $100 bill and send it to you! LOL
so the deal about thermal paste is that it transfers heat from processor to heat sink so the cpu does not heat up.
no thermal paste means the heat is not transferred out and your CPU is overheating and automatically shuts down. in facts thermal paste is one of the most important aspects of your laptop.
:) buy and apply some. Consult the manual to know where to apply.(the manual is online just google your model which is at the back of the laptop)
I've just got this laptop and i've noticed that where the gpu is at the thermal pad and the aluminum that is to the cpu isn't very helpfull for heat dissipation. aluminum isn't ver good for heat, if it was then you would see it on the cpu to. I removed the thermal pad on the gpu and also the thermal paste on the cpu, put a copper shimmy on the gpu to help the aluminum and termal paste on both sides of the copper shimy and the cpu.. I used artic silver 5 and haven't had heat issues.
Nice!!! that´s was exactly what I looking for !!!
great video! I have used that second song in many productions! gotta love freeplaymusic!
This is why Hp has lots of bad ratings, They are a GREAT company, but their design planing is very complicated and made to be not opened. I have a Hp DM4, cleaning the Heat sink is a big pain. I'd recommend taking to a computer shop to have it fixed if yours is. :D
very helpful video...but i was left with 5 spare screws lol...but it still works ha!!!!
Excelent video. You saved me money. I did the job myself. Thanks
I have a blackscreen and blinking LEDs (caps and scroll lock)once every 2 seconds. The fan is on quietly, and the media LEDs are on as well as the Power and AC Plug lights. Yet all I see is a blank screen.
totally agree! this is alot of dis-assembly. i have the HP dv6000 & i hate it, nothing but problems. i am just gonna pay a tech to clean the fan.
Amigo, soy de Chile, Gracias por tu video. Me sirvio Mucho.
Saludos.
Y gracias.
Oh gosh I was too busy dancing to the music i forgot to watch so IMA watch again. Like like like
Thank You very much, that was very helpful...
thanks :D this was really helpfull even when i have a newer HP this helped me ^^ now i just nedd to find out how i get the freaking screen to work XD
Thank you very much your video.

@bustedbit its the same... thanks for ur answer
Super cool mate, thanx for this. Is it the same procedure for HDX18T ?
My fan is still giving me trouble and is now making a loud noise so we are going to replace it with a new one. But after I put my laptop back together the wifi wasn't working anymore. It keeps saying something about the Local Area Connection 6" Adapter, so I think I may have damaged something while I was in it without even realizing it. The wifi light will not come on either, it'll connect to the internet with an Ethernet cable but not wirelessly now. Can you please help me to figure out what the problem is asap?
.................you had to dismantle the whole pc to get to the cpu fan? woahh.
Now can someone tell me how hard is it for HP to make cleaning lids for CPU and GPU, which could make this cumbersome task turn into 2 minute solution!?????
i took a short cut i broke the plastic from behind and i used the vacuum and it worked lol
Thanks man. Helped me and my friend divert disaster. Liked, faved, and subbed!
Video helped so much, thanks.
thanks for the video, how often should i clean the fan? and another thing... i like the music that you used to this video, could you please tell me the artists, songs or album .... Thanks bro. you a have a good taste for music too !!!
@estrickland89 yeah i have the same prob... blackscreen and blinking leds... i search for help and now i found out that the CPU is not working good... but the last few days i worked on without a problem.. now i just restart my pc and i get this..... well now its time to open up the laptop again... just hope the CPU is still good to use...
Nice 1 man, help me a lot
A client of mine has this and she states that it does not boot up.
I tried booting it up with her batter and with her power cord, but it is not booting up.
She states that she bought it from someone of craig's list for 50 because she has one at home that is not booting up as well.
After seeing this video I feel like returning it to her and telling her to invest in a new laptop.
This is one of the most tedious laptops I have come across.
So whats the justification on manually spreading around the thermal paste. That could create tiny air pockets.
Try this next time: Apply a small dot of paste to the center of the CPU/GPU.
DON'T TOUCH IT WITH YOUR FINGER.
Square up the heat sink to the CPU and gently lower it without pushing down.
Screw it back into place moving diagonally from screw to screw. This will evenly spread the paste and maximize its spreading.
Also this could explain more /watch?v=EyXLu1Ms-q4
HI MAN A VERY GOOD VIDEO, BUT I FOUND A ERROR IN THE END IN 13:04 YOU CONNECT THE WHITE CABLE IN THE BLACK POINT AND THE BLACK CABLE IN THE WHITE POINT. IF YOU LOOK AT THE BEGINNING THE ORDER IS DIFFERENT
Thank you dooo much.... i was greatly helped me....
una pregunta,,,,en el video el tipo limpia con alcohol comun,,,tu con que lo hiciste y esa pasta q pasta sera para comprarla???? gracias de antemano

My lap is death , thanks ! by now i need a retrotime machine.....
TKS.....very much....
this vid is really helpful, thank you
nice man, you are the guy!!
On my computer all the lights on the keyboard turn on, and you can hear the fan quietly running. There are 4 Blinks on the Caps Lock and Number Lock buttons but nothing shows up on the screen. what is wrong, and who can we send it to, to get it fixed, please help SOOON.
Hi, in 01:40 you are unscrewing a screw that is partially worn out on my laptop. Can't unscrew it without risking more ware and I'm running out of ideas. What can i do?
The noise my fan's making is driving me up the wall.
I don't know if my fan works or not... how do I have to connect the wire of the fan? with the copper tips up or down? In the minute 8:55 - 8:57
@w4tch4cl4wschannel well not putting any thermal grease and mess up your computer by over heating and freezing but if thats not whats happening then idk.
Well that's way more complicated than I thought it would be. Probably not the best idea for my first attempt at opening up my laptop. My fan stopped working a while back and now if I run my computer on anything besides power saver and try to play videos or run a lot of programs it shuts down. Any other options besides this or bringing it in for an expensive repair?
