Thanks for keeping the 'DOH!' moments in. It makes me happy to know I am not alone.
Thank God a UA-cam video not talking about new amd threadripper cpus
Big lol
Having pulled a couple of Lenovo laptops apart for cooling system issues I can sympathize with missed connectors. You are bot fun and informative to watch and I wish you many successful days at the shop.
Done watching, thank you very much for the informative repair video. I have learned significantly more troubleshooting & repair lessons in this tutorial video and to your other repair videos as well compared to my ENTIRE 4 YEARS OF COLLEGE due to the rotten & outdated standards of education here in the Philippines. I hope you will soon have a mini-series for Schematic & Boardview-free Voltage/Power Rail Tracing[12V/18-20V Main Voltage Rail, 5V, 3.3V, CPU/GPU Core Voltage Rail, DRAM Voltage Rail, IGPU Voltage Rail, System Agent/Northbridge Voltage Rail, PCH Voltage Rail, BIOS Voltage Rail, Battery Power Rail], Proper method of testing/checking of potentially faulty MOSFETs & ICs/Controller Chips, CPU/GPU/PCH Reballing and BIOS Bin File Editing.
You can reduce unwanted solder spill on gold plated mounting holes by applying kapton tape before you start.
You watched Mr.Solderfix ey? 😀😀😀
@@marcellipovsky8222 Yes, of course, he is incredibly skilled. :)
Maybe also a good idea to test before replacing the rear cover :)
A "Jiffy" is 1/100 of one second. It took you multiple Jiffy's to get the connector off. I'm not an expert in the measurement of Temporal Displacement but I did sleep at a Holiday Inn Express last night.
Experience does not prevent one from making mistakes. Experience just helps you find the mistake quicker.
1 tip.. careful w moving too early and pads rip... anchors melt faster than the small power pins as heat has not spread thru yet and rip a pad (if it was hdmi or usb)
light taps first while monitoring the data or power pin melt. (in this case no small pads so it was safe)
hot drop i do w a solder pen on anchor pins and very low air assisting to keep it melted longer as i alternate anchor pads melting w pen.
its good that you post unedited video so others can learn from minor mistakes.👍
Also, you can get a replacement motherboard for this model for around £20. Depending on the cost of the jack and your time, it might be more cost effective just to replace the board. I did this recently on a repair job with an old Toshiba laptop that had broken usb ports.
But presumably the windows install then has a wobbly because the SSD is in the "wrong" computer?
@@neilshep50 I used a fresh install of Windows and copied the user's files onto it.
Ehh no, repair is all about keeping stuff out of the e-waste pile !
@@intrax2tv Well.. you are saving the laptop at least ;)
can’t buy honesty, you sir are an honourable man
You still look like a Pro... no harm done (LOL). I remind myself of all the times you've taught me well and take solace. Keeping the faith etc...
That wick looks super coarse. Plus, using wick always generates some waste. Those holes should be easy to clear with a spring-loaded solder sucker (poor man's desoldering gun).
Lenovo ThinkPads use captive Philips screws for the bottom cover. USB3 power jacks are soldered to the motherboard.
On most of these Lenovo consumer models there is a reset hole with a recessed button that allows you to turn the mainboard on and get to the Novo menu without the keyboard or power button being connected. Unfortunately sometimes the novo button is on the power button board 😦
Great video dude! # keeping it real
perfect! as usual
"Let he who has not forgot to plug in a connector cast the first stone."
Last time I cleaned my gaming rig I spent 5 minutes in panic mode after re-assembly because it was stone dead, turns out I didn't connect anything to the front panel header ( power button included ) 😄
Last time I cleaned mine I spent 5 minutes coughing from the dust. Somehow, computers manage to transmute regular household dust into a mix of soot, pepper and enriched plutonium.
a nice DC fix
I really hope you split the fan and cleaned out the output filter fins. I am sure they would be clogged with dander.
When you give Lenovo hate for soldering on the DC-Jack, please point out, that this is Lenovos "No-Name" line of laptops.
A proper ThinkPad will have a DC-Jack that will most likely survive an impact like this and is modular ;)
Yea this is true, I'm not super fond of ThinkPads either tbh, but I do respect that they're a different league to the consumer line.
I would like to see Honeywell PTM7950 application..
did you put that resistor back in you dident say
And please do a video on failed EC or SIO am not sure what its called but i think its equivalent to SMC of a macbook
Hello adamant it jonas here from ETH I've been watching your videos and they are really educational. I would like to thank you on behalf of everyone trying to learn this stuff including me so thank you very much !!!
And i also need your help master teacher😜
Ive been diagnosing an hp dv7-2270us pc and it got a messed up pwr btn connector all pwr rails are good and trying to short NBSWON#1 to ground to start the laptop does nothing ive the 3.3 & 5v rails and when measuring the NBSWON#1 PIN on the connector it has 0v is this ok? Schematic of the board can be found by the name of the pc or its "Quanta lx6/lx7"
Self-punking is the best punking.😁
When did you find out that you (re)moved the small capacitor? During editing? (just a curious me)
Yea, I was just speeding through that bit, saw it, and was like 'wait a sec back up did I just... ffs... good thing the devices is still on the shelf.'
@@Adamant_IT 😀 better this way than finding it out from the comments 😉
Err how many times have I seen you put covers on only to remove them again? Oh well 😁
Why would an A-series APU make you angry or break your heart? I mean, they're kind of old, and they were never a high end part, but for their time (pre-2017) they were decent (in terms of both price and power consumption).
Edit: apparently this laptop model is from 2019, so I guess that's what you mean; they're using a previous-generation APU (essentially a 3 year old chip) when Zen / Zen+ ones were already available.
techically if the laptop allows charging through type c you dont techanicaly need to charge from the dc jack
That's surprisingly few laptop models. There's a couple of models that can charge from DC-in or from USB-PD, but most of the time the only reason why a laptop will have both is because it requires more than 65w for peak performance, and it's cheaper/easier to add a DC-in jack than build a 85+ watt USB-PD interface.
Do you have any experience in fixing Xbox controllers?
OK, color me confused. What's so bad about AMD APUs? The only AMD chip I've used that was memorably awful was an Athlon II Neo in that one sort of diamond shaped eMachines that tried to be a nettop and a multimedia thing at the same time. Could fry an egg with that CPU in seconds, despite it having all the maths abilities of a particularly rusty mechanical adding-machine...
I think it's because that specific APU was pretty old by the time Lenovo released this laptop model, and there had been better ones available for at least two years.
Happy accident lol.
thank you every word you said is true about this lying cop
he is justifying all of this and will never admit the poultry DNA he has
I thought all the Lenovos for a decent while had that rectangular jack, although maybe it's just the business spec ones
