Chosen Solution
My Macbook Pro recently developed a range of issues within the last day or so. The battery indicator, both the software one and the hardware one on the left side of the laptop, have stopped working. The fan is at full power even when every program is closed and the case being cool for a running laptop. The keyboard laptop back-light stopped working, and the laptop no longer goes to sleep when the screen is closed, with the screen and apple logo on the back remaining on. It developed this problem after I accidentally bent the power cable at a weird angle and screen went black and the sound of the video I was watching cut out. When I shut it down and restarted it, it had developed these problems. Any help would be welcome.
