Dell Latitude E5440 dead, no power, motherboard repair - Perfect Friday job 

I just ordered for a usb meter from AliExpress. I have this Lenovo Y700 tablet that just went dead from charging. So i decided i want to fix it myself and i have been watching a lot of your videos and learning a lot. Hopefully my first repair goes well. Hehe

People love you, that's why its very easy to send you gifts. You Are Worth it. You give your time and Knowledge to people for FREE and you can not buy free will. A decision you made willingly . Your an absolute ASSET. Thank You so much for your time .

Just to thank you for all this you are doing for us, it really makes a difference! I have been always curious about electronics, specially about fixing things. Yesterday I became very glad and thought about you when I was able to fix a USB Docking Station. My friend should throw it away but I asked him to let me take a look at it. It was dead... completely dead. Straight away, after following your methodology, I found out the main power rail was shorted. You learned me to be suspicious about capacitors and so it was, a capacitor was shorted to ground. I removed it and voilá, it worked! Then I wondered: should I replace it "later" or should I replace it now? Specially knowing the capacitor was in parallel with another one. Then I decided to measure the sound capacitor to find it was 33uF. I went to my tecjunk box and found a board with a capacitor same size, same value. Replaced it and crossed my fingers thinking "I hope it will not get broken within the next three months otherwise...." :) Again, thank you so much Sorin!

Cheking for short, no short ! 😅 Sorin the best !!!

I want a Sorin t-shirt that says "We have pictureeeeee !" on the back it has "Fixed using calibrated wire"

Thermal camera job. They do make life easier sometimes. No cap no problem, hehhe! 😀. Love your vids Sorin. I've even started to use your vernacular e.g. 'eets working!' , 'i come wiv beeping fing' keep it up and merry xmas.

There are always good people on the Earth, if they are able to send gifts.

I'm learning so much from this man. Thank you

This is a niceeeeeeeeee laptop, I am currently using its next revision e6440, I picked it up very cheap, put in an ssd and 16 gigs of ram, amazing for work. Much better build quality than modern laptops.

La multi ani, Sorin! Felicitari pentru tot efortul pe care il depui pentru aceste clipuri ca noi sa invatam ceva. Multumesc!

Good job mate 👍

Great job! Had same one in for repair! Quiet nice build Notebooks!

The capacitor will be replaced in the next video 😂 Sorin for President of Romania 😊

thank you

Nice simple fix and cool present!

Hi Sorin, great job troubleshooting the mainbord and explaning the schematic, thank u let me learning much more every day, bye Francesco Timpano from Florence Italy

well, my native is Hungarian, and we have a speaking "ajándék lónak ne nézd a fogát", what means "don't look at the teeth of a gift horse" :) Other way, i live in southwest Slovakia where inhabitant´s native is mixed of Slovak and Hungarian, so we have a version of that speaking, as "ajándék nyihaha necsumi protko" - which means the same, but, with some joke :D keep up with the great work, greetings: Benedikt

I got one of these laptop this year. Same model same issue.

I picked up an Asus C302 Chromebook for £12 inc postage!!!!! On eBay. Was faulty due to milk spillage. All I did was removed the mobo and cleaned it and it worked ever since. Does need a new bat now though. And yes I know..... Chromebook.... Hmmm but its great for watching movies on the bed. Plus its a high def glass 1080p touch screen.... My Bargain of 2023.

Its a nice feeling to solve a problem, its like a natural high, merry Christmas Sorin :)

every laptop is nice for sorin :) good jop,bravo 👏

Sorin , This man is a legend !!! Keep on :)

Hello from Greece. Thank you very much for your videos. they have helped me a lot. I wonder if you could make a video showing how the power supply that charges the laptop's battery works, using a multimeter and an oscilloscope, and showing the voltages before and after the mosfet and the waveform that activates the gates from the bq chips. I think you understand what I mean. thanks.

Fewer capacitors means less to go wrong in the future, I hope you charged the customer extra for the upgrade!

I am from Nigeria, I appreciate all your videos. Thank you for your lectures, I have learned much from your videos. Please do you have a live stream question and answer section ?

Dell latitude is best laptop i have used ever. I have dell latitude e6510 1st gen lap. Still working properly. It's 13 years old now.

Hello, good job, Regards 😀

I have this usb tester. it will help you and you can reverse the input/outup coz of the low resistance. The menu switch is not very friendly but can do your work. As for the missing capacitor, I'm waiting for the next video.

Please Sorin, can you do video on how to disable short circuit protection on linear DC power supply? I have one but I don't know how to do it. Thanks

I'll send you present too from morroco think you

We expect the capacitor to be replaced in 2030.Greetings from Serbia

I like Dell :) watching :)

Sir sorin what king of thermal camera you used :)

Sorin !!! Very nice resolution and smooth microscope camera. Which is it???

Sorin....we will not complain if you use a pry bar....instead.😊

also in Italy, '' a caval donato non si guarda in bocca''

Sorin u pushing about 3amps with low voltage before mosfets and voltages can pass through?

Of course ! replacing the capacitor ! Lol

"finally friday" ...again, LOL ...time is moving too fast

Nice present! It's very true, you should never look a gift horse in the mouth! - Good to see you not using pliers to remove a capacitor and that you're going to replace the capacitor on another video, maybe you're not so 'dodgy' after all... ;)

SORIN!!! I can't believe you do dodgey repair and not replace the capacitor!!! 🤪😜😝😅🤣

❤

X for doubt

Sorin, what model electric screwdriver you use?

Hey, sorin, come on, please replace the capacitor 😂,,, ❤

😍😍😍

Easy Breezy 😅

Thanks I have a question, Asus powers on but nothing more, no fan spin no nother indicator light, power bottom can not even force shut down What could be the fault and remedy

At 6:26 PD401 seems dodgy. Seems like this job is gonna come back soon.

Great job Sorin, i had a dell laptop almost identical to that one.I INJECTED 3AMP AFTER THE CURRENT RESISTOR NOTHING GOT HOT ,4AMP STILL NOT HOT. I SHORTED THE CURRENT SENSOR TO GROUND IT WAS SHORTED. I DID 2 MOTHER BOARDS SAME OUT COME. WHAT WENT WRONG.I'M DOING EVERYTHING THE VIDEO TELL ME TO TRY STILL NO RERESULT. THANK
