Diagnose & repair a unique fault, a hard one! How to trigger power output on a locked battery

[@CrucialSpeaks]

....WOW! How great to have that depth of understanding of these. ... from a 45 year component level technician! - BTW I ALWAYS SHARE YOUR VIDEOS! THEY ARE THE BEST EVER!

[@erdaler1682]

very intelligent solution, thank you very much Mr. Sorin..

It’s really hard that you re working with many different brands and models of laptops every öne has different design hard job.thank you for that Good lesson.

🤗👍👌 exactly what I Had on my tablet , I did what you always do, because I brought a multi power supply like you , and a multimeter, battery was taking zero volt. I had to shake the battery by cells and then became to charge. This is because I didn't went on internet for few weeks and I turned of the tablet for long without charging... For a reason the battery discharge on Android google as if we turn off the button. So these chrome works like that, you must charge it as if you don't use it. I have the same plate battery, only one of the two. This is because I listen to your repairs and brought the material, that I'm able to do it, because I had to open the tablet. Last year I changed the battery wich was dead, after fifteen months non stop well working. So thanks for the video!🙏💚🧡

[@patriciaoudart1508]

I add also about my quad-core chinese tablet, working well every day, since two years, became my connected source, having also my phone on it, the USB C port have been made independently from the mother board, so it is moving a little bit, but working well. But this is amazing to be afraid in that way, always thinking the port is dead, and no, it is fine every time I had opened the tablet, thinking this would be why the tablet not charging.. So think this will be useful. I brought a USB charging cable that is blinking red and blue when talking to the S IO, red when charging and blue when no current more. So, imagine when the tablet not coming on, the cable standing blue, the cells saying zero volt, and my variable power supply sending 2amps for nothing charging. So this is a conceptual issue not a material issue. I think this is not either a security, this is a back door on the system wich is not made to let your computer account off the outside net control. They yant you to be a consumer, non stop. Not being so free!!! that you can put for a month you device off without being connected to data they find in domestic current, wifi, 4G, bluetooth triangulation. As turned off, your computer keep sending informations by those ways, so big data knows you anyway, and keep an EYE on you.😵 If you stop this, the sanction is immediate😱, and your computer is dead. Some will buy a new, some will learn at electronic repair school!🤗👌🙏💚🧡

[@ytrew9717]

2:00 what is a "frozen super IO"?

[@frozendude707]

I think he is referring to that a super I/O chip runs some simple firmware to change states and have different modes and such, if it cannot change states anymore for some reason then.... I have also experienced similar problems, usually removing all power and letting everything discharge forces it to reset completely, which often fixes it.

Hello, Sorin, great videos. Can you please tell what type of microscope you use. Thanks.

[@algis3207]

Hi! You said you ordered a new battery, did that fix the problem?

[@Iceking007]

On occasion when Batteries fall below a threshold voltage they will no longer take a charge, and the monitoring circuit sits the system down. It can be possible to force charge the battery and get it above the threshold voltage, you'll get some more life out of it... but is a sign of EOL.

[@pheneaschiwenga3392]

Is it possible to force charge it using a dc bench power supply

[@frozendude707]

@@pheneaschiwenga3392 Yes you can do that, but some controllers remember that the battery is bad and will not let you charge it normally again (to prevent battery explosion), so you can only use it until the charge is gone again or you reset the parameters of the charge controller.

I received a few weeks ago one laptop from a customer. Dead short you'd say as well, but was exact fault. Only I did not go through such long process. I started to unplug things as always I do, and when I've unplugged the battery, laptop has boot up. But yes, this is not a most common fault. I don't remember if I've got a video about that laptop cause I've got too many of them now :D and few weeks ahead as well.

[@diytechspirit914]

Use your battery analyzer and unlock it and then charge it thrue analyzer to test it.Might as well use it if you have it lying around.

[@westsenkovec]

Read the description. Also, this is at work and not his home shop.

[@diytechspirit914]

The power port on the motherboard, not the port on the small board with power switch, has a broken and twisted pin. I ordered a replacement and installed. I still have no current at this port and battery is not being charged at either port. Can I try to power-up C-433t without motherboard power port?

Possible to add own bms board to the cells? Battery gauge won't work but will at least charge and discharge safely, right?

[@gile849]

Bms yes, cell is good but 0V on output.

[@ytrew9717]

I'm not sure to understand: was the problem caused by a (or few) faulty cell (but the rest of the battery is working)?

[@surgingcircuits6955]

I think the charging light "flashing vs solid" was a hint.

[@colinsmith7379]

Hi I have learned so much from you thanks a lot. With this laptop have you tried unlocking the battery with the machine you reviewed some months ago as it seems like the bios uses the main battery, just a random idea, I think it should be illegal for them to make laptops like this that won't work if the battery goes flat it seems like they have included a chip to stop the battery from charging anyway thanks again.

[@theflowbox]

I already seen this video... is an old video before you have the Romanian battery analyzer, I think now you can use the tool to unlock that battery

[@patriciaoudart1508]

This is a big issue because in a collapse case, those tablets and computers can't work without battery, this is the case using power by solar panels, wind or Tesla antenna. So we need to know how to pass the battery controller. One thing is to have batteries in reserve and charging a little time every day. But this is nt nrmal that the battery discharge as we turn off le tablet, or computer, that means it never go off.

[@BilimTek26]

Sorin, I think you bypassed the battery protection circuit. It seems very dangreous, battery can be overcharged.

[@MrRvdbeek]

The battery is dead. That’s what the super IO thinks. Is the battery dead or did the power stay to loo for a long time? I have a chrome book and same story. Did battery test did charge it fully and did use it for more than 8 hours whiteout charger. So battery is good but the driver says something else.

[@pjhb_microsoldering_portugal]

If some battery cells have low voltage, you could try charging them directly from your power supply.
