Sorry the mic was a bit hot for most of this video - at some point it accidently got put on max input volume, so it was horridly clippy while I was recording this.
Sound is fine, not loud or clipping.
I do those kind of things all day, every day... and after work I watch your videos to relax and unwind, idk why it helps but it does. It's probably watching someone else do the work and reaffirm the way its done, anyway thanks, knowing what its like to work in a computer repair shop I'm surprised at the amount of videos you manage to put out, although I wouldn't mind to see even more.
I've done the captive nut repair a couple of times myself. My solution to not gooing up the threads was to put a long screw in. This has the added benefit that you can see better how well the nut is orientated, to avoid mis-aligned threads on re-assembly.
32:31 well...that happened to me personally once. If I remember correctly, it was on some older Lenovo/IBM T series with a thicker fan, and after spinning it with compressed air, magic smoke appeared right next to connector and the fan stopped running. But the board was fine :) Since then I disconnect all the fans when I blow them.
Or you can hold the rotor while blowing it out and you won't have that issue. You can also spin it way faster than it is designed to go on the axle which can also damage it.
@@Dejan357 Of course..."It is easy to be wise after the event." :D It was more than decade ago when I learned by my own mistakes.
Assuming the compressed air blows the fan opposite its usual direction would a measly diode not protect against such woe? If so maybe some machines have them and others don't which might explain why it only lets the smoke out sometimes? Forgive me if I'm full of shit though which is very possible.
As you said you were lucky in that there was a mass of plastic surrounding the anchor points for the brass standoffs to offer additional mass to support glue up. A lot of the time those brass inserts are in plastic pillars with vertical supports that fracture to heck. Nice to see that the customer was ok with the cost of the replacement screen top. It always amazes me that some people abuse their laptops so much after the hinges break to the point they fail outright rather than getting the issue fixed when it is less costly to repair.
Had an MSI laptop in here where the heat pipes were several mm too long so that they obscured the hinge screws so one had to remove the heat sink and the attached fans to get the display assembly off. Just as well since there were huge clumps of car hair in the fans and the exhaust vents.
Great video as always! As for the fans goes at 32:00 i once connected a fan to another while blowing air to the first. The second fan started spinning like crazy from the generated current...to the point it broke due to high voltage. A motherboard however might have a diode to prevent current flowing into the system but i'm not sure.
1:16 that was a sublime subject repositioning
Thanks very much for your videos. Very informative. You've helped me out a few times without even knowing it 😎😎
Great learning and screen repair.
One of my favourite youtubers Mr Sorin uses hot glue to good effect to repair screen hinges and frame. I was very sceptical until I tried it for myself and it does work and longlasting. This is economical diy and easy solution if you do not want to spend a lot of money. Controversial but it has its use and application.
Love your videos. Don’t know what it is but man I can watch and listen to you fix computers for hours!!! Keep it up!
When I worked for hp I had a PC, a Unix workstation and a terminal on my desk, all made by hp and all with different keyboard layouts. The only way to stay sane years ago was to set everything to US layout which at least kept the punctuation marks in the same place. UK keyboard layouts have mostly settled down since those days.
@Adamant IT, you could try and propose to your clients to invest on a (complete)shell for the laptop. The repair that you'd done on the hinge inserts does work but your client will walk in with the same issue, albeit the issue is double what you were dealing with in the first place. You should be able to find shells for the laptop(top, palmrest and bottom as one) provided you get them at a good price and then refurbish said laptop.
Not saying what you did is wrong, I just ended up receiving the laptop...again after hours of hard work and reverse engineering. Also, that screen looks like the person who uses the laptop sneezes at it's screen :P without looking the other way. Makes you wonder what needs undivided attention when sneezing, HAH!
Keep up the brilliant content! + have a like!
;)
Great work as usual. Did you redo the thermal paste off camera?
I have many older HP laptops, compaq 610, hp 550, hp530 and few nx and nc series, all of them have dual antenna WI-FI.
My new omen 15 also haves dual antenna Wi-Fi.
Probably just their cheaper new models don't have it.
Basically anything made in the last 10years onwards that isn't a business/pro class device.
And yea, you could say "well pavilion is the low-end stuff, why so surprised?" yet no other brand (except lenovo on their low-end tat-books) do single antenna wifi.
@@Adamant_IT Thats interesting, I have many laptops at home, mot of them beeing HP and I never noticed that, must be lucky that I got all the good ones, because all of my samples have dual antenna and an intel module powering them. The only laptops I have ever seen with a single antenna is the CHUWII HeroBook and some chromebooks.
I’ve successfully fixed hinges with hot glue. Makes it real solid.
Been watching Sorin? xD
@@justinspiredfallout I taught him that trick. ;o)
@@wiseemhanif3386 How dare you, Sorin is the source of the hot glue.
Great video. Thanks for sharing 😁
Tip from a technician to technician :D loose the nut on the hinge a bit.. its the reason why it broke off in the first place, overtime one or both hinges starts to open/close harder than it was from the factory we can both have same laptop an it will never happen to mine, no hinge is the same even though it looks the same. And yeah they sure are not build to last you re right.
hope i made my self clear i am still learning english :)
thats my best therapy :)
Very nice job Graham! Kudos
Did you consider giving the customer the option of upgrading the wifi module itself to a dual unit?
@@TheSpotify95 Not always an easy job with HP laptops - they mainly use a whitelist of authorised adaptors meaning you either have to source an upgrade on the list for the specific laptop you are upgrading or you have to jailbreak the laptop to fit a standard one that is port compatible like I had to for my otherwise working fine Envy.
Try hot glue like Sorin does, I have tried to use epoxy several times but it never holds. Either drill and make a mechanic hold or hot glue !
You know I think the reason his method is good although he makes it look messy is that the material is somewhat flexible unlike having some metal attached to plastic.
Hook a fan up to a multimeter and hit it with the compressor. You'll find it does indeed generate a small current however they're usually protected by diodes so I believe you are right in not worrying about it.
Should have used hot glue, it works great, learned from Mr Sorin on Electronics repair school channel . It's one of his ™️😂😂. Nice work anyway
This works in some instances, by virtue of; "it can't come out if every mm cubed of space around it is full of glue", but personally I'll leave it to Sorin.
In this case, gluing plastic to metal in a 4mm thick display assembly? Absolutely not. It'll snap off again under its own weight.
@@Adamant_IT You're job is great, i think it time consuming rebuilding the original sistem, it does not matter what technique is used as long as it works and hold. I appreciate you're work and for sharing you're knowledge, everyday I learn something new.
'Keep grabbing the bottom and it will all pull out'. Words I didn't expect to hear in a laptop repair video. Yeah. I know. How droll of me. lol
I love the rant about the Wifi! I have a Toshiba netbook (hahahahaha remember those?) that has a dual band wifi card in it. I do still use it. Threw an SSD in it and put Linux on it and she still works good!
You should do a Steam Deck NVME SSD upgrade. If you get chance. Very popular topic right now!
Sir, very nice. Can you please upload a video on medium complexity (with microprocessor and microcontroller) pcb repair when you have an identical good working spare pcb ?
1:19 I have the same series laptop (14 ce) and it failed 100% the same way. Heck, even the side of the hinge mount that failed is the same.
Seems the screen also went with it. I don't even know what to do at this point.
Regarding a spun fan putting out enough current to damage: Sure I've had it happen on enterprise equipment such as 5U servers with large diameter hi current fans, (HP 350 Gen8 for example) but never on consumer grade fans. I doubt a consumer fan would have the electrical potential.
Graham ... I have to say Customers that can't even give the laptop a clean before bringing to You is a Bugbear of Mine .... State of laptop Reflects on the Customer ( In my opinion )
I agree with this to an extent. Most people don't know how to clean their laptop, which is fair enough. What bothers me more are the ones who are shameless about it and don't see anything wrong with the filth. Aside from the fact that it's terrible hygiene and unpleasant, dirt and grot does damage laptops, and people always seem to be surprised by this.
I do like that you make mistakes in order of operation at times and catch yourself. Guess that does prove you are human after all. ;)
Super Glue and baking soda is something a lot of people use to make a strong bond.
8 bars and blocking the fan while cleaning works well for me.
19:34...."It's a little bit hairy.....it's okay, though" Adamant_IT.
unlike his fooking arms :0 (lol)
I commented this because I happened to look at the screen (while listening in the background) to notice just how bare he seems. [ I'm not wierd, honest ;) ]
Great content, as always.
:)
35:54 and the worst is, the backslash is where the RIGHT CTRL KEY SHOULD BE!!! 🤦🤦🤦
I don’t think there’s any correlation between dual band and dual antenna WiFi cards. You can have one antenna for both 2.4GHz and 5GHz (like this laptop) or you can have two antennas just for 2.4GHz (like most pre-2012 laptops).
This is correct, but my point was simply that high-end wireless isn't expensive, provides massively better user experience, and has been widely available for over a decade. It's unacceptable that any modern laptop doesn't have decent wifi in it, given that literally everyone uses wifi.
i have another word lol planned obsolescence lol
did you replace the thermal paste as you didn't show it in the video Graham
A Diphyllobothrium latum lurking inside a laptop? 😀
I had to do this epoxy repair just the other day on my sister's HP 17 ca. The posts that hold the threaded inserts are a lot flimsier than on the model you have there, very little material around them. Hilarously bad construction.
Hi Graham. I have an HP laptop, quite old!, and the thin plastic clips that hold the ZIF ribbon cables to the touch pad, keyboard and display have become so brittle that they brook into pieces. Is it possible to buy a new ZIF socket, of the correct size, and transfer the clip to the old connector? This would save me having to unsolder and re-solder :-)
I've not tried replacing zif connectors before... but if it's just the clip, usually inserting the ribbon, and then wedging in a piece of thin card above it is enough to make a good connection. Then add some tape or a tiny spot of hot glue to keep it in place.
@@Adamant_IT I was thinking about hot glue as well but then its a pain when you next want to un do it 🙂. Been using some tape as a temp measure (bringing my 45 years experience as an electronics engineer to bear) I will get a new connector and see if I can transfer just the clip part across. Will update you. May I say I love your videos. My Wife often passes a comment of Oh, not watching Adam! I have told her that's not your name
I just checked the fan voltage while blowing compressed air. The highest voltage I could generate was 0.025v
I've kinda-sorta been looking into this but not seriously, and it seems to vary wildly depending on the fan.
So while it's not always going to be a danger, you never know in advance, so you have to assume that it can be a danger.
Ok, I've just finished checking the voltage outputs for a 4 wire, 3 wire, and a 2 wire fan. The 4 had a max of .048v, the 2 came in first with 1.036v, and the 3 wire was the originally posted voltage (.025).
I hate to nit pick but was there 2 screws missing form the laft hand fan, if not my error?
Got some advice for you on hinge repairs. Makes life a little easier and can completely build up the walls around the brass gromet... Message me if you'd like to know. Thanks again for your videos :)
With refitting the insets, rather than tape, couldn't you screw a screw into the insert (removing the screw whilst the epoxy is tacky)?
I've tried this, and either ended up gluing the screw into the insert, or pulling some of the glue up into the insert, either way you end up with a failed repair. Taping off is fiddly and time consuming, but definitely yields the best result.
@@Adamant_IT - okidokie 🙂
Sooo... Did you replace the thermal paste?
I forgot 😅
It got done later when I noticed the temps were still a little high for a freshly cleaned laptop
Almost looks like an "I left a pen on my laptop and snapped it shut" incident, if the user has a habit of doing that I could see that repair having been done before.
I was wondering: did you clean the backside of the bezel at the location of the webcam? So to be sure the plastic in front of the webcam is clear (without any fingerprints)? And a question about your screwhole repair with capton tape: would simply screwing in the nut not simply do the trick?
The problem is there is a chance that the end of the screw would come in contact with some of the epoxy at the bottom of the brass standoff and get glued in place.
Doesn't polish make it droppable?
What's your opinion on using hot glue for this kind of job? Because where i am from, the back covers aren't always available or they are too expensive
On the display assembly itself, I can't see anyway that it will hold up for more than one or two open/shut movements.
I know Sorin from Electronics Repair School is a pioneer of hotglueing the hinges into the bottom case though - I think that works there because you're basically filling all the empty space with glue so nothing can move (because there's nowhere for it to move to) but speaking as someone who _can_ get parts, I think this is a bodge fix.
However, if you've got no other options, and can't even get it from Aliexpress, then it's worth a try.
You seems to have good experiences regard laptop computer and i think iv seen couple video where you swap a good old HDD into SDD. My mom got a laptop and it is god damn slow and i dont have pattience to deal with it since it way to slow compared to my computer. So i adviced her to get an SSD and a good cleaning inside since it never opened before. Now.. how to i tranfer all she got on HDD (include windows) into the new SSD if we decide to buy?
I don't have a video on this yet, but there's lots of tutorials on transferring windows between drives out there.
With reference to the fan spinning and causing damage at 32:30, CareyHolzman did a video a while back which debunked it fully: ua-cam.com/video/k9KA-xLLQXo/v-deo.html&ab_channel=CareyHolzman
I have a laptop with the hinge plastic screew part broken. I will glue it with cyanoacrylate or a glue called b7000. What do you think about it. Hi from argentina. I can't import a new part from Ebay or something like that.
I much prefer American keyboards, my iMac, 2 Linux machines, iPads, iPhones and Samsung Tablet all have roughly the same layout. So on the rare occasions I use my Windows laptop or dual boot it feels really awkward. I know it’s a traditional British layout that Windows uses but we’ve moved on from typewriters and iMacs are often in offices now.
I don't mind either, as long as their consistent. I can switch layouts in my head when I see ANSI or ISO layout, but when I see an ANSI layout that's actually ISO... that's just a confusing mess.
Built in obsolescence is a ‘thing’.
I know of a medical device which stops working after 200 treatments - it’s in the chip 🤬
Don't forget about printers, they're incredibly notorious for this, printing a set number of pages or having a timer that makes the ink expire or refusing to print black without color ink.
Damn, i just noticed is that a tattoo of a wave function you have? Did you study any physics?
I did not, I just have a passing interest in the topic - I like the ideas it raises.
👍👍👍👍
bump
Which Epoxy?...
I honestly don't understand why HP still hides screws...
Don't' sweat the small stuff
The keys have faint writing.
"Can You Damage A Fan or Motherboard By Spinning a Fan Too Fast?" -- CareyHolzman
Honestly, plastic holding hinges together is such an obvious and repeated problem that the only explanation is its built to fail, the only excuse for it are cheap laptops but it's done even on more costly $1000+ laptops which should be made to last.
Also of course planned obsolescence is a thing, printers are incredibly notorious for this kind of thing, printing a set number of pages or having a timer that makes the ink expire even if you haven't used any of it or refusing to print black without color ink, they get away with all sorts of shady tactics.
For reals. I straight up tell my customers that modern inkjet printers are a scam. I don't fix them, service them, install them, or supply them. I'll have nothing to do with it.
For people that actually need to print, I tell them to get a compact colour laser. Maybe even a mono if you only print documents.
"I might want to print pictures..."
No you don't. No one prints pictures. You print the odd document here and there that doesn't need to be colour. Spend £100 on a monolaser, you'll never replace the tonor cart in it's lifetime, and it'll never break.
Speaking of plastics: Construction material (Chemical Engineers) and its manufacturing process (Plastic Injection Engineers, don't you know? The pattern, that is, the manufacturing company either? ... come on man ... poor quality = cheap cost.
Nice repair, i'm surprized that the hinge doesn't screw at all to the side of the screen, that's a lot of tension going on here, may explain why it already breaks once :/
32:00 A french youtuber actually made a video to see if the myth is true and... yes it is on some fan ua-cam.com/video/HqV88yxWnG4/v-deo.html
To give you a quick resume in the video as i'm belgian and my main language is french, he is using a dremel to make the blades spin and use an osciloscope to see what's going on and some result are really bad, for example a "good" Corsair fan can generate 24V
(result are in 5:37 in his video)
Interesting, I also want to check current output, and also how fast fans can get with common dusting airflow on them too. I did preliminary tests and also saw decent voltage from fans, but this was whilst trying to spin them as fast as possible, not just a passing gust of dusting.
Theoretically possible != Actually likely to happen.
Till maybe 4 years ago I did not like HP laptops at all. From driver issues, too slow for the specs, failing HW, ... and that was for maaaaaany years. HP laptops for some kind of repair I got the most. Okay I am repairing stuff here and there but anyway that was bad.
BTW, how are HP laptops today/last few years failure wise❓ I just see in my country most of used laptops ads is HP 🤣😂
It's hard to tell. One of the reasons why HP appear so often in my shop isn't that they fail, but that there's _loads_ of them out in the wild. They're sold as a premium brand by big box stores, and people trust the name, even though the HP Consumer sector is the same questionable quality as any other consumer-grade laptop.
@@Adamant_IT yea sadly is true. I miss the old days, when manny laptops lasted, my friend still has old HP laptop for over 15 years I think and still running. Anyway thanks for response dude and thank you for your videos 😁👍
As a non native speaker can someone help me out here, I dont understand why multiple different youtube people prenounce etc as ekcetera. where did the k sound get in? I am genuinly confused. Thx for help
The internet Search Engines ARE you friend - in 2022 !!
Happy to guide you through the process of 'how to open g00gle'
It's a common pronunciation, but yes it's technically wrong, there is no K!
@@Adamant_IT thx, yeah I figured it was a commen tongue thing its just weird to me (also in my native language) people choose to just do it wrong because no reason. I ment no offense
I own this type of HP laptop (or did) the build quality is terrible. HP did not make these ones to last...
It's the backslash that annoys me with HPs. There is only one place for a backslash and that is left of the Z. It is bad enough teying to explain the difference between the backslash and forward slash as it is, and putting tnext to each other on the keyboard is just unforgivable.
I don't like American enter keys either, I mishit them.
Wera screwdrivers are the best.
Oy vey. This is why generally if someone asks me for a laptop recommendation I'll ask if they're averse to going used market and if so if they're willing to just...buy a used business-class machine from an office liquidator or such. Because at least as far as my experience (Dell Latitudes and Precisions and a couple HP Zbooks) business-class machines are built to better take the rigors of everyday life moreso than most lower-end consumer-grade laptops. And much easier to service, generally.
Though that kinda dodges the overall problem: I thought it was decided long ago that this kind of design (brass inserts in weak plastic) was bad and that we should move on from it? It's 2022, and I know this laptop's got a few years on it, but it isn't THAT old. Load-bearing components shouldn't be made out of cheap plastic. Oy. Really have to wonder how much money HP saved by doing that.
HP sucks
I think you should wear gloves before handling that filthy screen 🤮
Are you saying planned obsolescence isn't a thing? Because it is. Companies do want your money, and a lot of those companies have no qualm with selling you garbage that they know is garbage. To that end, I wish HP, Dell, Lenovo, et al. would stop making these trashbooks.
I think built-in obsolescence implies malicious intent, "rigged to fail" so to speak. And I've seen many many many instances of people shouting Built In Obsolescence when something fails due to reasonable wear and tear (it just aged badly) or due to user abuse. I've seen the way people treat their laptop/phone chargers, cable/port failure is abuse, not BIO.
This is what makes me weary of the term, because it's very often misused. But as I say in the video, there are plenty of instances where it can only boil down to gross negligence or malicious intent, both of which are as bad as each other.
@@Adamant_IT It's hard to prove malicious intent, but during my time spent primarily repairing laptops for a local chain, user abuse is exceedingly common. However, a lot of laptops just aren't designed with what I'd call "normal usage" in mind. Kind of the same problem I have with all-glass smartphone designs--they're incompatible with normal people doing normal things. I do believe laptop makers intentionally design low-end models to fail more quickly in order to push more customers to the midrange and high end when they do break.
I hate HP laptops for their stupid keyboard layout as well. Won’t buy them.
Graham, you breath to much chemical stuff. Now all is good, but in 10, 20 years of this regime, it won't.
People think that I'm taking deep breaths over the top of the soldering iron. I'm not - I'm actually holding my breath, and I release when the smoke clears after a few seconds.
I do plan to sort out an extraction system - but yea, I'm not huffing this stuff...
@@Adamant_IT Good. Was thinking also to the products you use to clean (screens, keyboards). This stuff is also (very) poisoned and was not intended to be used 2, 3 or 5 days a week and breathed regularly like you do. Neurologic issues will come. Not now, sure, but it will. Take care.
