Acer Aspire ES1-512 won't power from battery

[m3g4tr0n]

need help, got an Acer Aspire ES1-512 that won't power on from battery. the battery is fully charged. no battery leds light up.

if i connect the ac adapter the laptop will power on without pressing the power key. it'll also charge the battery. (battery was 50% - now 100%)

if i disconnect the ac adpater the laptop turns off then i have to switch off/on the ac adapter to power on again.

it won't power on from ac adapter if i disconnect the internal battery.

ACER ASPIRE ES1-512-C5YW

remove the battery and plug in the AC adapter.
then, press the power button and measure voltage on coils.
