Seen a few posts about setting battery to ‘Primarily AC’. I can’t see that as an option in Windows power management. Is it a BIOS setting or an addon?

  • It's a BIOS setting

    Thank you. Will have a look tonight.

  • It's in the bios, some alienware systems rely on the battery to get stable performance, since my laptop lives on the desk most days I set a costume battery profile which starts battery charging at 50% and ends at 55% this prolongs the batteries and avoids any stress on the battery
