Acer Aspire R11 Power Issue
Good afternoon-
I have an Acer Aspire R11 netbook (similar to a Chromebook) with a SSD hard drive and Pentium processor, manufactured in 2017. It is having power issues after allowing it to sit for a couple of months unpowered. The battery when plugged into AC shows to be fully charged (left blue light on right side of netbook) but will not power on when I press the power button. If I unplug AC and use the battery disconnect button through the pinhole on the back of the machine it will then power up (right blue light) and work after plugging back in AC- when doing so the battery shows on screen as fully charged. However when the AC is removed it will immediately turn off (or if netbook is already off will not turn back on after removing AC) and cannot be restarted again until I go through the procedure I just described again. I have replaced the battery with a new one and it had no affect. I have read elsewhere that maybe the AC adapter could be defective but seems unlikely since the netbook will operate on AC once started through the procedure I described. Is this a motherboard issue or something else?
