• I actually start by disconnecting the battery. Older laptops with batteries that pop off, its a quick way to tell if its the battery or not. its a bit of a hassle now that they are inside, but its often the first thing I try, then I check the power connector.

• If they’re going to use USB’s and at that, 1 usb c, could they at least put it on a daughter board that costs $10 to replace.

• I just realized that sorin, and rosin have all the same letters and only 2 letters are swapped.

• If I had your tools, I would have done a million times better job! Your work is just incredibly sloppy.

• It's Christmas soon😂 The laptop in a festive mood🎉😅!

• Hi Sorin what is the name of a spray using

• Flux name please sir

• You identify the problem well, Sorin. As soon as we begin a customer relationship, it's there ready to bite. I had a PS5 come back after 6 months of fixing the HDMI port. Of course, the fix should last longer and I've never had port come back so I take it back. Not able to say if was impacted again, but just reflowed it again no questions. Sales even worse, especially refurbished. Every problem the customer has (like not being able to look up stuff online) and another load of support messages come back.

• This is not a proper job sorin, a proper job would be to desolder the connector, rebuild the traces, secure them with mask and use a new connector, or the same connector if it has no problems.

• Nice one

• very nice repair i loved 👌👌👌👍❤❤❤❤❤

• LOL – I've never seen a laptop with chocolate damage before!! I remember when laptop power jacks came on a very easy to change cable rather than soldered directly to the board.

• What might cause the damage on a fairly new laptop?

• ❤

• I think the chocolate was shorted 🍫

• Using uv mask was so not dodgy. 😅

• There is a limit to what repairs can be covered by warranty.Im not sure about the UK legislation but here (southern Europe), i never offer warranty on liquid damage repairs,mechanical damage and pad restoration,such as this broken port,hinge jobs(even though i never had any returns or complaints),normal broken charging ports,hdmi ports etc.Even on simple capacitor short circuits ,what warranty can you provide?After a month, something might break,like a PCH/cpu/gpu.Customer will never believe you if you tell him "ok warranty only on the replacement cap,this time your cpu is burned to a crisp."Customer doesnt know what is a cap or a PCH,customer knows only a dead or a working laptop.So no warranty /money back, only a free 90 day destimate on whatever similar issue.ofc normal warranty on ram memory dimms/ssd.

• So, what we are checking first? Signs of chocolate, then water, then burnt mosfets (or, when all combined, hot chocolate) obvs, ho, ho

• i prefer the port to be replace… a lasting repair should be on the top list

• I have problem. I dont know how to find main power rail. How you know in just one second what is main power rail?

• A suggestion – take a vacuum to that fan

• Sorin can we use USB 3.1 Type C Connector 24+2P Male Female Breakout Board this type of repair?

• 1 I/O should be banned, ie, Mac's sux. Performers always use Mac, and of course with one I/O it wears out quick and ruins the show when it stops working due to bad connections.
  I would hot-glue that – lol -.

• Ive watched so many of your laptop repair video's that when ever you say "what we checking first" I always say to myself "power rails" and I can easily identify where they are 😁 Love your videos and I always look forward to your next one 🙂
