Hi. I have a Acer Aspire V Nitro VN7-791 My laptop automatically turn on and off. When turn on, only the keyboard has light and the ventilators start to work, but the screen is dark. Afer 10-13 sec, the laptop turn of for 2-3 sec and than turn on again for 10-13 sec. Automatically repeat till I push the power button for a few sec. That is the only time when permanently turn off. If i push the power button or plug in the charger without touching the power button, the laptop start to repeat again the same problem. My battery is not good anymore. I just used from the charger from a few year.

    This problem is to do with either your main battery that needs replacing as your laptop is an old laptop and if you still have the original battery then the battery needs changing, so buy a new battery and then do a hard reset with taking the main battery out and the RTC/BIOS batteries out and take the RAM out also, leave all components disconnected for 15min and reconnect them all and reboot the laptop, as this should fix your reboot problems, if it doesn't then your laptop has internal circuitries like a mosat and/or capacitors issues in its primary power stages at either the 19V or 3.3V stages, that need analyzing by an experienced tech that will chase the problematic circuitry components and change them, as a user like you can't do anything except change the old battery and do a reset.
