Hello
I have a NEW Aspire E1-731 and when i insert the battery it says "pluged in not charge", i have this laptop in my store sealed in a box for 1 year and it's out of warranty now.. 
I have try the ACPI unistall method and to plug in the battery when the laptop is on but still nothing, i have also buy a NEW battery but again the same.. i have also try a new power adaptor with no results.
When the laptop is off the battery led is blinking orange.
OS is Windows 7 with latest drivers from Acer site, but i don't think this is software problem.
Can anyone from ACER told me how to repair the laptop? i'm laptop techician..
This is the link from my laptop. Barcore (4713147088485)
