So to you Sorin my infinite appreciation and eternal respect! Thank you sir x from wee bony Scotland 🏴
Sorin thank you so much.
Exact same laptop similar issues all working fine now ^^
Your a gentlemen and an awesome teacher thank you again.
आपका हर vidio मेरे लिए helpful होता है सर 👌👌👌
I don't miss your any video related to laptop repairing
Tanx for the good teaching.
Whatch your videos Almost every day, i love electronics And you Are the best on you tube…
Thank you.
excellent teaching on Laptops, etc, thank you ...
thank you brother I have exacly the same problem, I went directly to remove the bios battery and its working now , but the fan not working , very strang this models of DELL , maybe I will have to do the same manip as you for the cpu fan but i prefer for now to find how to fix it without putting the wire to 3.30v , thank you so mush
hello Its me again, the fan was not working because this model doesnt lunch the fan automatically , so I was waiting for 3 min to let the cpu hot then the fan started turning , Probably you didnt need to fix it with the 3.30V cable, good to know , thank you brother
How do you keep track of all the screws and cable placments.
after 5000 laptop repairs you get used to it
Hi, thank you so much for this video.
Thank you my dear teacher ❤️
Very good teacher. Thank you
yep ive opend a lot of those lots of screws but they are prety desent systems
Hi Dear,
i like your videos , you re the best !
in this video you lose a lot of time because you test with the wrong power button , for the Dell E7240 pwr btn is in the right not left ( in the left is sound button)
thanks
I have a Dell Latitude E7240 which powers on but no display and no hdmi output, when I plug the charger in the system boots up without display:
- Power button led comes on
- Hard drive led flashes once very quickly
- Battery led comes on for one second
- After 4 seconds the power button led goes off
- After another 4 seconds the power button led comes back on and stays on, the hard drive led flashes once very quickly
The green leds on the actual msata SSD light up
If I leave the system in this state then the cpu and heatsinks get hot and eventually the fans will spin (but still no display)
Pressing the power button once will turn off the system (cpu will cool down, msata leds will turn off)
I’ve tried the following:
- Performed hard reset / static discharge, disconnected and checked cmos battery (3v on multimeter)
- Replaced RAM, msata, screen with known working
- Tried booting while holding down ESC, D, FN keys
- Tried HDMI output (no output)
I’d really appreciate any other suggestions / tips, could it be a corrupt bios? Thanks in advance
Could you have fixed it when you cleaned the spots which were water damaged, and pulled the ram stick and reinstalled it to test it? Water damage sometimes causes corrosion at the contact points.
I don't understand the fix with the fan... when LT was powered up fan started to spin when LT turned off the fan stopped, why needed that jumper wire?
Because when it was running first was running full speed all the time, he didn't want full speed all the time as it would be loud and inconvenient (I guess), so jumped it onto another chip with a voltage of 3.3 so it would run around 65-70% load and because it's piggybacking from that chip it means it will turn off once the computer loses power.
I have started a DELL laptop job. It will not start. There is 19v in the first part of the power connector components mosfets etc. After that 3.3 and 5v etc is fine. But there is no more 19v. It i all 13v. I see you bumped into that on this tshoot so was disappointed when it stated to work as I wanted to see if the 13v was supposed to be there or possibly it sits at that until it starts up.
When this model was new, I had it as my work laptop. It was good, but I still prefer Lenovo. Unfortunately you have to use that brand, what company have chosen. It was my first Dell as before that our company used Lenovo ThinkPads. Dell Latitude & Lenovo ThinkPad series have 3 year warranty, but obviously this model is already older now.

Se poate alimenta un laptop de la pinii bateriei laptopului?
That touching is an easy way to check for hot hardware - do that some I see
BE CAREFUL! BY DEFAULT THE FAN SHOULDN'T START SAME TIME COMPUTER STARTS, THIS MODEL LAUNCH THE FAN WHEN IT'S ACTUALLY NEEDED.
Probably master cut down auto fan management.
What is the power IC number of a dell latitude E7240

Is lighter fluid best thing to clean pcb-s?
This is Ultrabook, isn't all slim laptops so complicated to pack all necessary into that small package? OK, I started to think, that at moment I use ThinkPad X1 & it is much-much simpler inside, but Lenovo is 2 inches bigger also, which adds more space for components.
whats that liquid you use to clean boss?
Thank you so much but I have here dell latitude d830 no power no display completely dead

hi guys is bit hard for me to fix dead lenovo g500 motherboard special on the bottom side on PU401 get hot to much
Those old laptops had a lot of damn screws in them - as far as I'm concerned
What you mean with "old" as this model introduced late 2013 and it was basically 2014 model, so 5 years old(2019)? If you are teenager, then I understand, 5 years is long period for them.
what kind of liquid did you use when you cleaned the motherboard?
petrol

you should get a tray for loose screws fella, make your life easier :)
his desk is a mess, it's a miracle that he finds all the screws to put back, and just think of all the scratches he makes on all those devices.... cut the value of the item in half.
I would just vacuum whole place once in a while and source screws and smd's from dust bin for next repair :P
