My Asus worked perfectly until yesterday. I assume that the battery drained and AC was not plugged. I turned it on and doesn't chargeat all. It seems that something wrong with my battery. It works from AC but when it is plugged it shows only 4% available charging. When I unplug AC it shuts down right away. I already tried the 45 seconds holding power button method, and I uninstalled in device manager Microsoft ACPI-compliant Method Battery. Nothing helped. Does anybody has any idea?
