1) use wired antistatic device. 2) remember where the screws coming from (take it very serious, you will not remember without taking notes etc.) 3) take a pictures on where the cables was sitting prior taking it apart. 4) Be very careful with all connectors and other plastic parts. 5) prepare CPU and buy also paste like arctic silver (watch a few videos how to apply etc.) 6) be ready to find something is broken and need to be replaced or fixed with glue/poxy/soldering Than it should be easy. :)
These elitebooks are built like tanks and this teardown shows why: all metal, lots of screws, beefy PCBs for components and peripherals. They make for a lenghty teardown but they're less prone to accidental damage.
I needed to clean out the fan, which necessitates removing the plastic cover that contains the power button. After watching your video, I realized I needed to remove the capped screws. Voila! Fan is clean and purring now. Thanks!
Just bought a broken one with a really nice case and good lcd/webcam. Have a working one with a bad lcd/worn out case. This is going to be super helpful as i merge the two with parts. Thanks!

I work on photoshop at least 10hrs a day. Yeah, i bought the ram. I see i altered the speed by alot. Feels like a new laptop. I got this laptop in feb of 2012. its a awesome laptop just wish the screen was bigger. Thank you for replying.
How difficult would you consider just replacing the processor? I'm going from the i5 560m to the i7 640M. I know they're compatible. Just looking for a degree of difficulty. Thanks!
What is the screw driver for the star looking screw heads? Name and size would be helpful. All I'm looking forward to is to upgrade the RAM that's under the keyboard, unfortunately, HP got picky on the bottom screws on the 8440 and 8540 lines. I got the laptop that gets up to 8GB. For the other user who claimed 16GB was the max, he could've made a mistake or have other model such 8540p 1.7GZ Quadcore version ; I have that too. Anyways, any help would be much appreciated.
Hi! ..thanks for the educational video..Were the charging port/jack embedded on the motherboard? Or clip in?....can it be replace? Or need to replace the whole motherboard..
Indeed. is it possible for you guys to do an HP Elitebook 8540w? having some trouble with mine and needs to make sure everything is in the right spots. Thanks!
how to change the motherboard battery , that small cell. mine had been exhausted and when ever the i open it its in 1980. the battery of laptop is also dead but iam managing it thru direct power.
What sized bit is used for the heat sink screws? Mine seem a little stripped and I have no clue how I am going to get them off... Standard hex sizes don't work. IE. 1, 1.5, 2, 2.5... It is like I need 2.25 hex... And I know for a fact thermal paste will fix my issues... I just can't get it on :(
Hi,I have a HP ELITEBOOK 8540W. I want to clean the dust in the fan. It's very difficult to dismantle this type of laptop. So please give me some suggestions. Have a good day.
Is it possible to switch its NVIDIA NVS 3100M with a GT 720 or GTX 760? I have an 8440p too and I'm thinking of starting a gaming channel. Also is it possible to switch out its CPU and add more RAM?
+Micah Domine (micahbob091) If you're wanting to go that far, you'd be better off buying/building a desktop. Laptop CPUs are usually soldered to the motherboard, the graphics cards are onboard too. A GTX 760 is a desktop card so it'd never work in a laptop, so as I said, you could build a desktop. And you could add RAM but it wouldn't do much since everything else would be impossible to upgrade. I built my own desktop in the space of 2 days after receiving all my parts for under $500. And there's numerous tutorials on how to do so on youtube. You'd be far, far better off doing that and using your laptop for looking up gaming guides or something versus trying to game on.
Thanks. I've finally decided to actually get a gaming desktop. I'm going to sell my laptop for $350 on ebay along with my old trumpet for $178 to get enough money for a monitor and a $458 computer.
Micah Domine You're welcome, and for all intents and purposes,you should try comparing the specs of the desktop you're getting to the parts and possibly try building it yourself. Less bloatware and mark up for it being preassembled. Also, I used my TV as a monitor, just food for thought.
+residentevil5681 I was thinking, since I also need my laptop for school, and need the mobility, could I use an external graphics card? Does the 8440p have a PCI Express? I was thinking I could prop it up and have a GTX 570Ti or something hooked up underneath when I'm at my desk...
good afternoon I wonder if the laptop is you can put another card 2GB ram so you have 4 GB of RAM is that it looks good or not if I fixed than hope I answer my question
regazzz there is no such thing as a wlan/wwan slot. A pci slot and its modifications were created for various hardware like videocards, modems, wi fi cards etc.
+elisei01 Yeh its on the underside there are two slots one for Wlan and the other for Wwan but i suppose you are talking about the express54 slot on the right side.
Could I attached a webcam in to this model, and please let me know how to installed a webcam on this hp elitebook 8440p. Can anyone help me, thank you in advance.
Am using elitebook 8440p and my system freezes a lot i cant even play a video from my hard drive, but it plays without any issue when using a flash. i have tried running dick checkup and repair, re-installed window7 but to no avail. i recently read about updating the bios which i was told could be the solution to this problem. my question is this, how can i update my hp elitebook 8440p bios?
Hi I would like you to help me, I have one and I damage the motherboard, which is not the reference, indicarmela Might and recommend a site where I can buy it, please, I like my laptop and I want to change clothing to keep enjoying it, the problem it is that you do not serve the ports and told me that if I change the board can fix...
+Hacks free Juegos ONLINE there are lots of places online where you can buy parts. I would mostly recommend eBay, but from buyer to buyer it can be tricky. If I would need to fix it myself, I would get same laptop with cracked screen and replace what's needed. Otherwise who knows how seller prepared motherboard... Have a good luck!
Paul Stanton you know I can imagine how hard it is for a people who never did it. (I was in that shoes too)I would probably make an ultimate guide for all my videos all together. Otherwise if I would talk in each video I would be speachless. :)Meanwhile - you can point out on what exact time frame you are having a question and I will tell you what is it.Thanks!
regazzz Haha, yeah I am a bit clueless when it comes to knowing the insides or repairing laptops, and do appreciate your vid as it is useful. I was hoping to see if you took the graphics cards from the motherboard as I may need to do that, if it is possible to remove it. I have one needing the harddrive replacing, which I could tell on the vid, and it does look nice n easy. But my mate said graphics card too. Cheers bud
Coil whine, it's normal and you can't do much about it. Coating the whiny coil(s) with electronic varnish might help, but not by much. They will still whine, but less audibly. Remember to not coat thermal transfer surfaces. I recently repaired one of these laptops that did not have any thermal pads on the CPU/GPU power phases. They whine like crazy as a result of years worth of thermal throttling. The GPU was also missing one thermal pad from the memory chips. It had been like that from the factory. Amazing how much punishment these things can take.
I hope you cleaned the laptop when you opened the thing up😂 Bluetooth module is located on the front right side of the laptop, next to the speaker grill. One screw to access, check connection and if you just see wires it means you don't have a Bluetooth card and you need to buy one.
Guys i have the same laptop but when i click the power button the laptop doesn't work but the power light come and go for 8 times and stop how can i repair this ?
Deskins Technologies Hey, I am married and have 2 kids :) I am Russian, so in Russia married people wear rings on the right hand - it is that simple. So, no worries here :))))
You probably have a newer model... So far I know, more memory - more power for Photoshop. I would say you may feel difference, all depend on how hard you work in Photoshop.
This guy is just taking thing out, he will never be able to put it back together to have it work. He just ripped the keyboard cable out with out opening the little flap. Don't want him working on my laptop.
+Bill Maverick you should see how certified Dell repair techs leaving a huge gapes between palmrest and case bottom, same goes for Lenovo techs. Not all of them, yes, but some of them who fix laptops under warranty. Believe me, when I work on clients laptops, I am way careful than in this video. This video was made under totally different circumstances. Cheers!
Some parts threw away, probably were broken before me. (not sure with that laptop since it was a nice elitebook) In your profile it is written you are a contributor to Google Buzz. How do you contribute over there?
I think you are just over-exaggerating a little. 30 years certified tech, ok you did work on thousands of devices, fine. I have a friend who is not certified tech and has been working in the area, especially laptops and similar devices for more than 15 years. He does not even use a drill, just so quickly works with the screwdriver that the laptops are dissembled and assembled back in minutes. Yes he has a degree, but certified repair shops in Europe have some of the most inexperienced workers, who were selling cars before that or s.th else, then were hired for a low pay in the official hp dealer service. If you ask me, I have seen PC parts being thrown around much harder than in this video, and as long as you are careful with the screws, you wont be able to tell this laptop has been opened, if looking on the external. Even without anti static wrist band, I have seen hundreds or thousands of computers worked on and nothing happened. It is possible under some circumstances, but quite unlikely in the most. Of course you need to know what you are doing, so take care and god luck.
thats the magic phrase "as long as you know what you are doing".i also have worked without wrist band..but its all about proper grounding of your body while working.and yes i laugh at most big name repair shops.this wasn't meant to be a bashing just info for beginners ..i started with a tsr80 in 79 in 9th grade..so much has changed.
Johnathon Biersack There is no room for two slots, thats why there is one under the keyboard. Besides getting to the one under the keyboard takes an extra minute or so. Just 3 screws and 4 switches

9:45 There's nothing more iconic than the sound of a Samsung washing machine finishing with a Mozart jingle.
I have an LG washing Machine that plays a tune when it's complete. Always makes me smile.
7:17 did you do anything special or just a screwdriver under the frame ?
Great video, helped me disassemble this notebook
How difficult would you consider just replacing the processor? I'm going from the i5 560m to the i7 640M. I know they're compatible. Just looking for a degree of difficulty.
Thanks!
am planning on doing it since the speakers keeps breaking ans am suspecting a loosin wire

thanks for the video i had tough time disassembling it now it has became easy

Hi,

Good for you!!! You may attach an external screen - bigger size ;-)
If a device is overheating, which components should be removed, inspected and cleaned?
+Raymond Chiu clean cpu cooler, change thermal grease.
+Raymond Chiu Looks like CPU fan/heatsink can accessed and removed by taking out just the keyboard.
+Дмитрий Кочук Спасибо :)

Laptops never have a PCI-e card slot. A PC graphics card won't work in a laptop unless you buy an external adapter.
Good job
good afternoon I wonder if the laptop is you can put another card 2GB ram so you have 4 GB of RAM is that it looks good or not if I fixed than hope I answer my question
Hi, there are 2 memory slots so far I can see. 2nd under keyboard. Yes you can have 4gb for sure.

From a repair technicians point of view, that is absolute horrid engineering from HP.
Mind if i ask why?
***** unless you have more than two DIMM slots for the memory, they should be next to each other for ease of access...
Johnathon Biersack Yes but under the keyboard one is preinstalled,the one on the back is for extra, easier to get to
Johnathon Biersack There is no room for two slots, thats why there is one under the keyboard.
Besides getting to the one under the keyboard takes an extra minute or so. Just 3 screws and 4 switches
