Acer Aspire ES 11 won't start

Jan 24, 2019
Power won't turn on, yet the battery is not drained. It just blinks blue everytime I push the power button. I charged it for an hour and got the charging light blinking too. I unplugged it and surprisingly, it worked. After some hours, it happened again. The unit can't be turned on, the power light just blinks. What is probably the problem? Thanks!
