Dell Inspiron 15 3511

[jepienkowski]

Good day, good folks of the Forum!
I have a Dell Inspiron 15 3511 that was working perfectly fine before starting a screen installation. Then after getting the screen installed, the system will briefly turn on when I press the power button, but will not stay on...
If I press and hold the power button, the system will "stay on" but there is no POST or anything...
When I connect a charger, the system will power on immediately, and stay on. But no POST and the system can not be hard shutdown...
As there is no CMOS battery, do I just need to disconnect the power and the battery and let it sit for a while to reset the board?
I did pull the RAM, and am not getting any BIOS beep code errors.
The power light (where the charger plugs in) is solid white; no flashing or anything.
I disconnected the screen; still the same thing.
Disconnected the mouse, keyboard, speakers, etc = Still the same thing with the no POST.
Completely baffled by this!
Maybe I somehow killed the board, but if anyone has experience with this issue or one similar, I am ALL ears!!

Mucho appreciato ahead of time!

I did search the Forums for the Dell Model that I am working on, but could not find any similar posts. If I did miss something, I apologize and please send me in the right direction!

I have also gone through the Dell support pages thoroughly!
Including on how to reset the RTC.

Was the battery disconnected while screen was replaced?

Have you tried connecting an external monitor instead?

So I did have the battery disconnected when I put it back together, I also did try hooking up an external monitor via HDMI, but it would only "stay on" if I pressed and held the power button.
If I plugged in AC power, it would just turn on all on its own.
No post either way; just lights, capslock solid, and fans running at max speed.
For my client's sake, I just ordered a replacement board and they are back up and running again. But I'll be DAMNED as to what the hell happened to the old board... I have been doing this 20+ years and never had anything like this happen.
