Hello. So the story is the following. My keyboard was damaged and I took my laptop to a service. The keyboard was replaced succesfully but some keys were were too much inside. So I removed the backend of my laptop and noticed that my (internal unremovable) battery was in a wrong position. I took the screws out, placed thr battery in the right place, put the screws back on. Now the keyboard was looking good, keys weren't sunk in anymore. But when I pressed the power up button, I only got a black screen. Nothing pops up, not even the logo of the computer or the button menu. I can hear the fans running and the power button light is on, but I get no response whatsoever from the screen. Does anyone have any idea what happened?
I tried connecting it with a hdmi cable to a tv and looks like the video card it's fine, it displays right on the tv. Could it be that the guy I went to replace my keyboard to didn't connect all the cables right? He did a poor job with the keyboard too.
