I charged it fully, then set is aside.  When I returned days later, the battery was dead, so I plugged in the charger as normal.  The screen said that it was low charge, the performance may be lower than normal, use the correct 20W charger.I'M USING THE CHARGER THAT CAME WITH IT.Amazon said call Acer.  I called Acer, and ACER TRANSFERRED ME TO A VOICEMAIL THAT IS FULL AND NOT ACCEPTING MESSAGES.I called Amazon again.  They said they can't send a replacement, so I'd need to return for refund.I decided to text Acer customer service.  They are having me to a power wash on this new chromebook to see if that fixes it.  The power wash fixed the charger issue.Now the problem is the touchscreen is not sensitive like an iPad.  I sometimes have to hold the screen with one hand and use the index finger of the other hand to touch the screen several times for it to take on input.  This will not work for my application.  The device will need to be returned for a refund if this can't be fixed.  So I'm texting Acer again.  They say they can offer a repair services, but I'm thinking that since the device is brand new, this is how all Acer Chromebooks behave.
