Acer Predator PH16-71 - Won't start up unless connected to mains power, the battery is 80% charged.

Hi,

New here. Very recently purchased a brand new PH16-71 and loving it…but. I've noticed that unless the laptop is connected to mains power it will not start from an off state (i.e. fully shut down).

The battery is 80% charged and once the unit is powered up I can disconnect mains so I know the battery is good.

I've searched the forums and come up with a couple of suggestions but none seem to help. I'd like some confidence that this is "correct behavior" as I'm travelling to Europe with the laptop shortly and although I've got an extended 4-year warranty I need to know its working.

Thanks

Steve

    Hi Steve, this is not normal behavior, use the 330W power adapter provided with this laptop and not a USB-C charger. If you have Acer Care Center or AcerSense running disable these 2 services in Windows Services: accSVc, acsSvc and accAgentSvc, change the Startup type to disabled and click on Apply. In Windows uninstall these 2 battery drivers:

    and in BIOS disable the 3 USB and Wake from S4 (ignore the red box on the picture):

    Reboot to Windows and see if the battery will charge to 100%. If still the same problem, run a battery report with the command prompt: powercfg /batteryreport check if Connected Standby is supported and if the last full charged capacity is close to the design capacity. If you can't charge the battery to 100% there may be a power rail problem or bad plug/socket, and you should take the laptop to Acer Services in your country to check this.
