Dell Latitude 14 E5450 - No Power Fault

[@seckinseckin3919]

Explanation is very good. With that mobo photos, probes, voltage values on the coils, showing on schematics or boardviews, etc.. really clear technique to understand.. good work .. keep that format on your channel and im sure you will have many members this way..

I love watching these videos a second time, because I can see the broken cap from the beginning. Great video!

Very clear visual and verbal explanation! Thank you for your knowledge and for your time! ❤❤❤

[@therepairshare673]

Thank you. Check out my more recent upload for newer model laptops

Thank you for explaining this so clearly, slowly and methodically, learnt so much, liked and subbed... what are the implications of bypassing the first mosfet, is this a temporary fix until the replacement mosfet arrives? Also please can you explain how we can measure resistance between drain, source, gate to confirm the mosfet is indeed faulty.

nice explanation. Sub for sure! Keep it going amazing little different style of others showing problems you go to details with pictures so cool :) Respect! :)

[@repairchannel]

Thank you so much for your clear explanation!

After bios update i got this problem as I had imagined, there are no battery problems because today I accidentally discovered that when the PC tells me that the battery is low, I tried to turn the PC back on and despite the battery indicator telling me 0%, it's more than 1 hour that I'm using it. But now in this situation I don't realize when the PC will shut down, because from 1 hour it tells me 0%. It couldn't possibly be a battery problem because it happened overnight. Now, however, I have this problem that the PC shuts down after 20 minutes because it believes the battery is low, when it isn't. What can I do

[@СергейСеров-г4ю]

GREETINGS, PLEASE TELL WHAT CAPACITY IS THE CAPACITOR WHICH YOU DROPPED ON THE SCHEME AND WHAT THE VOLTAGE IS THERE, THANK YOU IN ADVANCE FOR THE ANSWER.

[@sanojechannel9797]

why not check the 1st mosfet?

Nice video, thanks :)

I need info on a 7212 rugged. No power no charge. Anyone?

It's too good sir

Hello can you teach me on Dell Latitude e5450 No Display,

[@therepairshare673]

It's difficult to give advice without seeing your laptop. With the fault described here, there was a short on the board, which caused the laptop to not switch on. However your laptop may have no display for other reasons. I guess the first thing to try would be to see if the power lights come on, and maybe connect an external monitor to see if it sending video to that.

[@jayriecoboyijib6162]

@@therepairshare673 thank you for the advice ill try that one first

[@nekelly123]

So where was the fault?

[@1967250s]

Shorted capacitor fried the power mosfet, so they both needed replacing.

[@СергейСеров-г4ю]

THEY ARE PAIRED NEXT TO PQ705

MAYBE THIS CAPACITOR RATE SHOULD BE THERE CAPACITOR 22u_0805_25v6m smd

Hi there, thanks for watching. From the schematic for Dell Latitude E5450 ZAM70 LA-A901P rev03, it shows 6 SMD caps between the power sense resistor PR701 and PQ705 PC732 0.1U_0402_25V6 PC713 2200P_0402_50V7K PC714 22U_0805_25V6M PC715 22U_0805_25V6M PC716 22U_0805_25V6M PC717 22U_0805_25V6M

Hello, could u help me to fix my problem with my notebook, when I connect a connector from power adapter, a computer charge a battery 🔋, but after a few time later the computer PIK and the battery wasn't charger, power adapter is connected, after a few time later the computer PIK again and the computer continues to charge the battery. Could u tell me what the problem is this. Thanks.

[@therepairshare673]

I'm sorry, what do you mean PIK?

[@makcimenuka7904]

@@therepairshare673 Hello & thanks for answering. PIK sound such as voice then we often connect or disconnect a connector from a power adapter to a computer socket.

[@therepairshare673]

@@makcimenuka7904 I'm sorry I just dont understand the term "PIK sound" - I've googled it and google doesn't know either. Is there another word that you could use?

[@makcimenuka7904]

Thanks again for answering. When anyone connects power adapter to a notebook, at thet moment the notebook gives sound such as notification sound on a smartphone.
