Hi
i buyd a new battery for my laptop . it wasnt a originala cer battery cause they arent  made anymore or at least that what iwas told by acer support. so today i put in new battery and laptop doesnt start. when i press power button keybord lights up fans turn on but blackscreen. whats strange is the little button(to disable touchpad) right to the touchpad is flashing/blinking fast. i tryd battery reset(unplug adapter and press the littlebuton for 10 seconds) 
what i noticed is the old battery sas TYP 6000mAh/88.8Wh Min 5700mAh/84.3Wh and the new one says 5800mAh/85.84Wh. i guessed that Min is for minimum power needet to operate so im above thtat and it should be fine to work but maybe not..
any guess what it is? do i need to send back battery?
