Charging only up to 35% - Toshiba laptop C50, board repair, bribed with candies :D

Hello, friends! Please, allow me to reinforce some VERY IMPORTANT advice from Sorin here: DO NOT TRY TO SOLDER WIRES ON CR2032 BATTERIES (or any battery, but specially on CR2032 "coins"). They get very hot very quickly and explode on your face, throwing acid everywhere and burning your skin (yeah, it happened to me, and I was VERY lucky that the acid didn't get to my retina, but it was a very close call). Washing with water just makes it 10 times worse, as the water reacts with the acid (yeah, also learned that the hard way). And yes, I know it works sometimes. It worked 10 times for me before the last one exploded. Don't do it, it's not worth it. Buy a battery spot welder if you need to attach things to batteries and be happy. Happy 2025!!!

[@bobpowell3301]

Nice post! I'm glad that you pointed that out. Thank you!

[@isaacn751]

there is a special tool for that , works with electricity not heat and can solder a little plate on the battery without damage , it solders thee plate with high current , so the way do it , you solder to the little plate your cable and the plate you attach it to the battery with the special tool that uses high current to solder

[@viniciusvbf22]

@@isaacn751 Yes, this tool is the spot welder I mentioned! Be safe! 😉

[@g4z-kb7ct]

@@isaacn751 There is zero reason to do that. You can just buy batteries with the solder tags on them already from china for $1.

Who's "greatest dell technician that's ever lived"?

[@ArandomHitman]

@@viniciusvbf22 It's a channel called "Dell Parts People" that specializes in dell laptop repair. I asked for any tips/advice for getting into something similar and they passed me off to here.

[@starfansubs]

Yeah I'm curious to see who

[@ArandomHitman]

@@starfansubs ​ @starfansubs I'm referring to a channel known as "Parts-People Dell Laptop Experts" on youtube. As odd of a name it may see, they're pretty good at what they do. I asked them one day how they learned and got the experience for microsoldering/PCB repair and they gave me the link to this channel.

Hi Sorin, I'm a French guy so sorry for my English but I want to thank you because I have been watching your videos for two or three months and thanks to you because I managed to repair my first motherboard. It was almost an easy pizza. Just the first Mosfet on the main power rail. Thanks again your videos are really cool.

[@ReparadorAficionado]

Sorin is excellent on his work and he also has sense of humor. That´s why we watch him.

[@alessandrovirdis520]

Toshiba's mosfets are your main pizza sponsor!!! 😄 Have a beautiful week Sorin👋🏻

Sorin, dedication, and experience is your best presentation, thank you for sharing!

you have adapter for that batteries , plastic thingy with wires where you put regular 2032 ( temu :)

Thanks for taking the time to make a video Sorin.

[@alirezanzdy]

Sorin buy a small spot welder, and then just use it to make the bios battery, so easy I always do it.

[@suprmeatdude]

Just use tape bro

[@Customer22374rt]

I Just use electric tape and it works always

[@tommytsg7742]

before I bought 100 brand new batteries for cheap I used copper tape to fit the original battery cable on 2032 and wrap it into heatshrink tube..

[@davidlguerr]

@@tommytsg7742 That is how I do it.

[@Doman2000]

As mentioned here already, just some metal tape and kapton to isolate works fine.

[@LetUsRepair]

Interesting how you get so many Dynabooks. I've never even seen one; Not for sale, resale (used) or had one in for repair 🤔 Always nice to get a little treat with the repair ;)

[@geovani60624]

maybe it's a regional brand

Same! Been doing this for so long and never had one in. The last Toshiba laptops I worked on were Vista / 7 era.

Used bios battery is a discharged bios battery. So long as it has 3v, it's new.

[@davidlguerr]

No, it is not new. A brand new coin battery will have about 3.3V.

[@h1234e1234]

Check your new probes with a magnet to see the wires are not made of iron, because lately we run that risk. Good video Sorin, and nice to see you again. Cheers.

[@h1234e1234]

If you are more interested in the subject, search on youtube: "Clip leads made with fake wire". I check mine and some are made with iron, i ordered those from china.

[@jurgenkruger3932]

I think it can be the voltage divider resistors which measure the battery voltage. But it can be also an issue with the control PCB inside the battery.

[@ZiadSayegh-v8u]

After the first explosion you won't do it again 🤣🤣🤣🤣🤣 Thank You so much Mr SORIN for the slightly long video (I *LOVE* LONG VIDEOS) AND SPECIAL THANKS TO YOUR INCREDIBLE BRAIN WHO COMES UP WITH THESE HILARIOUS JOCKS .

[@SymbolTech21]

Check the gate voltage. I think maybe there is some overshoot of voltage gate and maybe this causes to burn the mosfet. And check on the pcb traces if there is any gate resistor. And maybe changing that value will prevent in the future to happen again

[@alessiociulla8184]

Ciao Ottimo lavoro 👏🏻👏🏻👏🏻👏🏻

[@KeiLin11]

Bios battery with voltages closer to 3V is always brand new no matter where motherboard it came from.

[@rfr653]

Good job mate 👏

[@djtongi]

12:54 always a good idea to put sharp probes on a lithium battery and then put pressure on them due to bad contact... :D be careful!! don't get into routine... can be fatal...

[@joeanon1415]

Sorin, Try putting some solder paste on the threads, see if that helps your probe connectivity issue.

[@TechTronics7]

You can find those cr2032 batteries everywhere, from supermarket, pharmacy to gas stations because some car remotes use them or cr2016 - thinner version..

[@lagunafishing]

I think heat-shrink tubing over a replacement coin battery is much safer than soldering wires on.

[@warunakangara6791]

What a great brand new bios battery 😂

[@suprmeatdude]

I always have 5-10 CR2032 on hand. You can make your own "special" BIOS battery with some electrical tape anyway.

[@Luis_Sebastian7674]

I got a trick to replace those coin batteries without having to solder with a solder iron or even a spot welder, COPPER TAPE. 😎

[@Electorr]

sorin likes to build calibrated fuses from old wires 😂

[@circuicitis]

Sorin, I highly recommend you MaAnt P22A probes. They are sharp enough to draw blood on my fingers, they have replaceable tips, and the silicone wire never tangles and feels nice to touch. It always pisses me of when a multimeter plays tricks on me, so can relate :(

[@MikeG-rh1lk]

Its not about the size but where you measure from 😀

[@muhkuh5804]

Good job Mr sorin

[@g4z-kb7ct]

FYI Dynabook is NOT Toshiba. Sharp bought Toshiba laptop division in 2018 and since then they call it Dynabook. Sure it's still very high quality like Toshiba but now made by Sharp.

[@xristosglezellis3025]

Sorin you can remove the cell from battery and put a new one 😊

[@preytec]

Try burning the tips of the multimeter and dip them in WD-40. That should stop them for crusting up on you

[@rouuuk]

that bios battery is not small, its just cold :)

[@davidlguerr]

You do not need to solder them. Just rip off the tabs, then use another CR2032 battery and attach the tabs to the new battery using tape, you use a conductive tape and then isolate everything with electrical tape. Have been done it for years. Never bought any coin battery with cable, they are not that cheap.

[@Carlos_Eshuzao]

only one word...Master!!!!

[@gaetanodistefano9014]

actually is possible to use a normal battery there but you need to put a diode before the battery to stop the battery charge because of corse the cr2032 are not rechargeable. :/

[@cam70android64]

Mr Sorin, I bought the same multimeter leads, I'm very dissapointed with them, I preffer the other ones I got better measurements with them and can press beter in the components for the measurements.

[@mardina1a]

you can use 2032 battery just stick cables with tıght adhesive plastic tape no need to use solder they usually works as this

[@migsvensurfing6310]

Not something you would do as a pro

[@adaniel69]

5:45 Is that liquid damage? Between pin 2 and 3 on the bottom of the mosfet?

[@adaniel69]

Maybe on top, also...

[@hugovale8070]

soo what ? pins 2 and 3 are together in boot sides !

[@adaniel69]

​@@hugovale8070 maybe this caused the mosfet to get short...

[@loizostheochari1509]
