Damn, this fix complexity is quite above the usual problems that you have shown us lately. It was great to see you go into the more technical problems of faulty chips in boards but everything has a limit. Great video as always mate!
Sounds like there is a short circuit somewhere deeper inside the laptop. best thing to do is get some jumper wires onto the board (which bypasses the DC jack and power limiting software) and inject voltage until whatever is shorted heats up.
Regarding laptop repairs, There are many custom-made chips that you never ever find anything on the net. The biggest problem is the spareparts. You cannot find them either. So, laptop repair means having alot of doner boards. For apple computers that might be possible but for other brands that is just not possible. BGA is a big problem.

Those types of locking tab and connector are the bane of my existence, especially the incredibly small ones on the Nintendo 2DS. Those tabs pop off so easily, but don't reattach at all. What would you suggest in a situation like that? Great video, as usual, though. I love learning, and being inspired to work, from your videos.
I feel that! My first time in a joycon I broke one of those locking tabs. I couldn't find a solution on google so I just had to junk the board. It broke with the tiniest amount of force. It was insane.
always measure 5V and 3.3V on coils. if they are present, laptop should turn on. or at least LEDs should show something. if not, bios may be dead - reflashing will fix issue.
lithium ion batteries are often shown at their median voltage, not their max voltage. that battery is a 3p battery. 3x4.2 max voltage is 12.6. Median is 3x3.7 is 11.1v
Also many laptops use what they call LiHV cells that are regular Lithium cells with chemistries to increase service life when charged to 4.4V/cell with a total of 13.2V... Though I'm charging a modded phone battery moto-mod attachment where I use a 4.2V cell at 4.35V and researching let me know that the 4.4v is an upper-limit thing that gives more capacity with reducing capacity by a third (200 cycles versus 300 cycles service life). Most laptops that have LiHV cells seems to report a 12.9v peak charging when polling the device directly (Something Linux allows in most cases, except peasant-grade HP laptops et least) It seems that they choose 4.3v/cell for some safety margin and to give a few more cycles service life. It also explains part of why laptop batteries from 2008 can often still give 80% its design capacity and yet a battery from laptops of the 2016 and newer often don't hold charge well or swell up.

For the ball chip thing when i was young i used to work for a phone repair shop most of the times we fixed them by heating them up and just moving it a little so if any ball was connected it got fixed(usually) so you should try at least that maybe
@@BAERnado I don't know if it helped on his videos but we used to do it on the old phones until 2009 when i left. Putting flux on all the sides and heating it until you can move it just a little with a tiny touch and then try. And plenty of times it was fixed(other times not). Sometimes we removed them completely and put them back again after cleaning the board unless we broke it 🤣 but still i think its worth a try since it doesnt take more than 5 minutes
Regarding the battery, it is usual for the manufacturer to specify the nominal voltage (in your case 11.4V), which is simply kinda an "average" value, used to calculate the amount of energy stored in Wh (proper way is to integrate the voltage curve from full to empty, but an average works fine), just doing [nominal voltage] x [cell capacity in Ah]. The usual nominal voltage por LiPo and LiIon batteries is 3.7 volts per cell, so 11.1V on a 3S battery. When dealing with HV batteries, this nominal voltage can be a tad higher, so it is not rare to see values like 3.8V/cell (so 11.4V). However since the topping voltage is 12.6V from the schematic I assume in this case alienware is overly optimistic, because that is not HV topping voltage, is standard full cell voltage (4.2V/cell). That battery should probably have a nominal voltage of 11.1V too in order to give a proper Wh estimate, but w/e. So... well, both of the batteries looked fine to me. I see you traced down a problem with the charging IC and replaced it. Sadly no happy ending!
Send this laptop to the The Cod3r as a repair challenge. Locking tab are easy to replace from one connector to another. In your case the locking metal side plates form the outside hinge and needs to be bent a little outside to free the plastic pins.
Even if you could buy the chip, there's no way you could also program it with the required code. It looked like some kind of micro. So a donor board was the only possibility to fix it.
Great video, hate see that even with your great expertise you cannot fix it. Always enjoyable and informative keep up on the excellent content you provide.
Is it possible that a resistor leading to the 5V was broken in the the surge? I dealt with a board at work earlier that had to many volts put through it and caused the resistors to crack. Of course it would be hell to track down a pin size hole or hair line fracture on *at least* one of several resistors. Are you able to check any of the parts connected to that leg of the chip using the schematic? Or would that be a waste of time?
But that's a very small chip. I'm almost a complete beginner and was still able to reball a chip of roughly that same size using a 5 dollar kit from Aliexpress. The chip I reballed was an ARM from a JDM-040 PS4 controller board. It took only 30 minutes and one failed attempt because I burned a chip from a practice board at 480ºC (the right amount of heat was 270ºC with low melt solder balls and a universal stencil from the reballing kit).
I don't know if that laptop has a battery or not. But I would disconnect it if I were you, Steve. I have learned this the expensive way by having to repair an LVDS screen cable, and the LCD power supply circuit. And in the end if it is not fixable, send it to Northridge Fix. Alex does work on small BGA chips.
Said it before and will say it again, I do not understand why in the US, people pay so much for what is sold as "spares or repair". There is zero guarantee these things are fixable, and like with this board, even re-selling for spares is gonna be tough as you have no idea what is still useable other than the most obvious things that are not electrical. Here in the UK, you would take a risk at £100 maybe, but no way would you spend £300 on a spares or repair item, even if it's potential value is £700. It's like a form of gambling.
I think the chip replaced creates 2 voltages output. 3.5V (3v5). 5V. Typically the enable lines should have around 3v. Not sure if they are all enable high or enable low (en_l).
if you buy a chip to replace it it will be preballed so you could try and replace it with hot air, you don't need to reball anything, you can do it, i believe in you😁
Honestly I like your approach on stuff you are not familiar with to broaden your and our views. I would like to see you tapping on reballing though. I believe with your skillset it will be like any other journey starting with one step at a time. Basically there is nothing to lose but much to gain.
@@Tronicsfix Speaks volumes for the necessity of a good surge suppressor then. Edit: they make those small single plug ones now, so it's easy peasy to have one on hand.
It would have been nice to know what type of power surge you were having to deal with since it would have given you a better picture of what you might have been facing but this is just the breaks sometimes most people don't even think of what may have surged the line.... my experience is a direct strike is pretty much a futile repair attempt, a brush where you were close to the strike like lighting not striking the power line directly but close enough to induce a high voltage on the line or you are further down the line from the strike... sometimes you may fix it. and this is the area that a good surge protector can help protect you. Or the power company drops a 220 line on your 110 and I have personally had that happen odds are much more in your favor to repair it... and then you can have a Brown out and sometimes that can fry you electronics as well and odds are pretty much in your favor to repair it... all was ask if you can, but buying on eBay your often left in uncharted territory.
Reply to 13:55. As far as I know, there is not a single modern laptop which requires a battery to run. Power cable should be just fine. Actually, many batteries go bad over time, and require you to either unplug it, or replace it if you want good performance on your laptop. Since whenever the battery is low, your computer will most likely attempt to preserve the power longer by not using as much power on the cpu and gpu. Leaving you with a worse performance overall. Batteries going bad looks simular to regular low battery to the operating system. I personally had an issue with my laptop, where it kept trying to use battery settings even though it showed as fully charged. So I ended up unplugging mine and only ever using the cable to avoid the performance hickups.
@@Tronicsfix im not sure why it didn't post, i wrote like a whole paragraph LOL Anyway basically i said this: I have worked on this same motherboard before. on the CPU/GPU side of the board, check all the large main coils (all of them) for continuity to GND. Also i may have missed you doing this, but I'm not sure.. check the output of the chip you changed for continuity to GND. Im curious if the reason theres no output is because theres a short on that rail. The laptop i had came into my shop and ended up having a short on one of the coils near where you were working, 0.7ohms resistance to GND. when i injected voltage at that coil, a cap lit up on my thermal cam. sort of near the area but near what looks to be the firmware chip, there are two caps next to it.

Nice working on those laptops! Keep it up!
Thanks, will do!
Wonder if the power surge board could be used to repair the donor board, depending on its problem?
Oh, man i was really hoping you get it fixed 😩
Me too!
The enable signal is disabled when below 0.5v and turned on above 1.5v.
Checked the datasheet and compared to others from the manufacturer.
So something is pulling the output down and tripping the over current protection.
Or the reference is bad
That white component near the internal connector looks like a fuse. Did you check whether that fuse was popped?
Great video, hate see that even with your great expertise you cannot fix it. Always enjoyable and informative keep up on the excellent content you provide.

The battery voltage on the actual battery being different from the schematic may be just discharged vs charged voltages. Sounds like a HV 3s battery.

I'm a proper pansy when it comes to electricity. How often do you get something like this where you plug it in and it just goes "POW!" immediately?
a li-po 3s battery fully charged has 12.6 volts and avg 11.4 so schematic and labeling were right
What can break the solder balls on a BGA chip? Would that be from a drop/fall?
Yes, that can definitely cause it
for last step can inject 5v to rail with low amp
