Dell charging sign ON but NOT charging - Dell laptop not detecting the charger repair solution 

Is that now no diode no more protection

@@jcb208 Correct, no more protection, its Zener diode. 19:48 Marking is ".8" and part number is "BZX584C4V3-V-G". You can find schematics by that. Just one thing that Sorin almost never do, and its beneficial to really show, is to measure faulty part outside of circuit. Jokes aside, it will be pure example how faulty component looks like when measured with component tester outside of circuit. For single component there is always multiple parameters, with component tester we may see what is problem... For example if you measure diode in diode mode, you may get good reading with multimeter, but if you use component tester, then you can see it has large leakage current. Or ESR on capacictor... ESR is different from capacity, but they are both on capacitor. 20:36 - Diode is still in circuit and according to zener diode usage, there is always something in parallel, so resistance shown is not the one from diode.

​@@orion310591RSyeah, Sorij should test components after removing them, and should use more often oscilloscope, component testers and so on. It would bring more audience to his videos. A new layer of info that we want to watch

@@orion310591RS Please what component tester do you recommend getting?

do you also watch Northridge Fix? :)

@@needlethread4715 Yes i do watch nf too

Exactly my thought. If not much harder almost impossible!.

this dont work....i tried that 2 months ago, actually completly killed my battery, i have to now remove my battery to use the laptop....i also thought if i use the dock it will bypass the 1wire ic heck but it doesnt, it still wants the oem charger

@@jacovanzijl8904 I guess I am lucky that the E-dock worked for both of my laptops with this problem. I always use OEM chargers that are confirmed good in other Dell laptops to eliminate the charger as a cause.

How right you are!!! Can't tell you how many times we've cussed Dell for their charger foolishness!!! Even if you use a charger with more amps than is required, (but is a non Dell charger) Dell REDUCES the cpu output & won't charge! VERY frustrating, and NOT customer friendly at all!!!!!!!

what is the software you mention?

@@dimitrismaster ThrottleStop - disable BD PROCHOT (if I remember it right). It only helps with the CPU clock, not a no charging issue.

Best thing you can do is remove Winblows entirely and install Linux....for ANY laptop.

@@englishrupe01 might be true but these issues happens outside the OS of choice, so not sure Linux will help much in this case.

Yep. Dodgy repair bypasses design safeguards. Customer should be advised never to use a Dell Dock, or anything other than the small capacity power brick it came with. Then hope the brick does not fail and pump a destructive voltage or current into the laptop.

Ok, but why not replace it actually? Is it hard to find? Expensive? Too much time to order and wait for delivery? Why just remove the protection and risk much worse damage next time than simply ordering and replacing that diode? I really try to understand the reason here, is it just being dodgy and not doing it since it already works without it?

​@@moldeaux I don't know myself I have seen engineers do this many times... If it works leave it 😂

I just posted about my 2 bad E7250 and E7450 (of many units) where I brought out an old PRO3X E-dock yesterday (06/20/24) to finally fix the AC unknown issue. The dock bypasses the AC jack on the laptop. Now both units charge and run faster, and BIOS indicates correct adapter wattage (90W required for the dock to operate). The E-dock is cheap online and should work with all Latitude e-series laptops.

Great info, I was wondering why it still worked after the diode was removed.

Replacing an ESD diode, whatever next? Replacing capacitors?

Hi Sorin thank very much, Never stop learning from you, i have same problem with a customer i sold the Dell two Year ago just out of warranty, but the different is that my laptop d'ont power on, i must remove the battery and put on again then i seem to work fine, i tray your suggesting and leet you know...go on so then i a lots

OneNote is good solution for notes.... easy to draw schematics, easy to attach files, easy to search, easy overview with sections and pages... It will eventually grow into big database of solutions...

Did you talk to him? He did say he will offer you free license if you only do a few batteries a year. Very flexible and reasonable

In charger is a chip especialy in dell that derminate wats and is is correct charger...also to protect charger it self, and the bench psu only had positive and negative so laptop cannot determinate what type of "charger" is that and wont allow to work...i mean dell have some specific system but in general interesting fault...

Because the proper charger sends a signal/sinks a particular current so that the laptop knows its power capacity and charges the battery/powers the laptop accordingly. When using the bench power supply the ID pin is not connected, so the laptop doesn't charge as it's saving potential issues with itself or the unknown connected power supply...

If my knowledge is right, these power pins do come with with integrated stuff to make bench PSU to be identified as correct charger type by Dell, HP laptops & this is SPECIFICALLY HIGHLIGHTED by websites selling these types of adapter pin sets!

@@Aneesh.Asokan You may well be correct, but in this case his set does not appear to do that. Indeed in some cases it would be useful to have one set that does and a second that doesn't.

@@will_doherty I think that Sorin jump started that method to diagnose this fault! I have seen many online websites specially mentioning that their adapter pin sets specifically comes with integrated electronics to make Dell, HP laptops to identify bench PSU's as orginal chargers to make it work without this glitch! That's why I felt confused! Yes, Sorin must have used his own methods to diagnose this fault!

Try a bios update, or the copies batteries are just very bad

Nu, acel 3.3 este un "average" aratat de DMM, daca pui osciloscopul pe pin vei vedea ca pe acel fir are loc o "convorbire" prin square waves.

@@alexg9155 aa, asta inseamna ca nu ai nici-o sansa sa incarci bateria decat cu incarcator dell, sau ai putea reda acel semnal cu un spectrum analyser si cu power supply sa incarci bateria?

@@alexg9155 scuze, cred ca voiam sa zic generator de semnal, cred ca spectrum analyzer e altceva; inca nu le am asa bine

@@leerzeichen1910 Doar cu incarcator Dell din cate stiu. Acel semnal nu cred ca se poate emula pentru ca e vorba de niste date practic. Poate exista incarcatoare aftermarket care pot vorbi si ele, nu am cautat, dar cu power supply poti incarca bateria doar "pe direct" cum a mai aratat Sorin in trecut (intepi bateria practic) sau cu acel battery analyzer.

@@alexg9155 da, asta stiam. doar ca ma gandeam in ideea... ok, cum testezi daca circuitul de incarcare al placii de baza functioneaza daca nu ai incarcator original? te ocupi cu reparatii? stai in RO sau in DE?

Dell deliberately did this for security reasons, even though they actually wanted to sell batteries

Not necessarily but in this case it proves that you did not understand why this issue happened for sure, read the video description.

some people now have laptops with no ram slots.....that is the trend they want to push :))))
