Hi,
I searched the forums but I couldn't find my problem.
I have a G750JZ laptop, comes with a core i7 processor and a GTX 880M GPU. It is working flawlessly and is still in an excellent condition. However, as soon as I unplug the AC the laptop shuts down, or to be more precise, it powers off immediately.
The battery is fully charged (99% or 100%) but the laptop would not work on battery. It will not boot if I press the power button on battery, as if there is no battery at all.
Since my brother has the exact same laptop (G750JZ with the same exact specifications, we bought two units together) I tried to use his battery on my laptop, but it will not work. If I plug the AC, it will work again with nothing wrong at all.
Please, I'm lost with this problem although I have good experience in dealing computer systems.
