Mac shuts down when running on battery alone
My mac shouts down when is not plugged in. Specially when I watch videos on youtube or on a VLC. Now it's doing it more often, even when I'm emptying the trash.
Battery health is at 84%, and once its off stays the same way, so it's not the battery. It doesn't over heat (according to iStat)
I've opened it to dust off and still doesn't solve it, so it's not dust either.
Any help? Thanks
Is this a good question?
