I recently acquired this laptop and all I know is a bunch of them were donated to a non profit and they upgraded and got rid of them. I installed a ssd and m.2 drives in place of the head and optane drives that were installed (bios setting was changed to ahci before hand) put cover back on inserted an usb with an operating system installer on it and turned the computer on. It loaded the splash screen and about half a second after it went away the laptop abruptly shut off. When I plug the charger in there is no charging light, pressing power button does nothing(no back  Light, keyboard light, no fans etc). Ive done due diligence and spent several days looking at every post on herethats similar and have tried all recommendations. Ive put original hdd and optane in and done the same, charger outputs  19v, have tried without battery and more. Any help would be amazing
