Dell Latitude E7240: How o fix DEAD LAPTOP, No Power, No Display: SOLVED 

Well done, but twice bad points to Dell: first for putting a consumable like that battery in a place that's so difficult to access and secondly for making a BIOS which doesn't even allow getting into the BIOS if the battery powering the CMOS RAM is causing the latter to malfunction. They should be able to detect that type of failure and operate with sensible defaults hardcoded into the BIOS to at least give the user some options and decent error indication.

The first time was working as you showed me but when I put everything back in place. did not work ,☹️

why does this keeps happening work for some months then the same issue no power on. please help!

Is this permanent solution or temporary?

I tried but nothing. The light blinks & the fan spins then it cuts

My power button does light up and the charhing thingy when i plug it in vut no display

Can someone please tell me the type of cmos battery I need for this laptop E7240

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
