Wow Thanks so much! I think this is my exact problem. Too bad I already took the motherboard out and put back together after giving up. Guess I'll have to give it another try.

Hi... Bro My dell latitude e7440... Had the same problem... mechanic said that... Change the whole board

Hi Nasir, thanks so much for sharing this video. I have exactly the same issue with my E7440, which cannot be powered on. When I plug in a working AC Adapter to this laptop, the "power on" indicator on the AC Adapter will also become off, which indicate that within the laptop there is a short circuit. Here are my questions: (1) in your case, what may have caused that 19V short?? Was it caused by water damage or?? (2) other than 19v short, what other possible scenario that can cause the behavior that I described, and (3) are you located in USA and if so do you take mail-in repair for similar repair and how much you will charge for such repair?? Thanks!

Tengo la misma y tmb problema de energía siempre, 😮, no prende, creo q la venderé por partes

Good poz

Salam bhai, 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

you should slow down and give more details about your diagnosis

Nasir.. sup, I have the same exact Laptop but mines powers on and work functionally.. the issue I have is that the charger and battery 🔋 light flickers orange and then automatically power and it keep saying lower battery even with a half bar of power.. any thoughts?

Now that you have over 1000 subscribers - how does that actually help you in any way?
