Recently my laptop screen started getting very dim while unplugged to the point where I can barely see the screen. This is not an issue with windows power settings where it auto dims a little when unplugged. Manually adjusting the brightness has no effect, I can barely see my mouse when it's like this. This has to be a hardware issue because occasionally the screen will be the correct brightness when not plugged in. Unfortunately, I'm out of time to do an RMA, typical, especially when you spend $1500 so I need some help.
