A fair number of laptop makers include a power management tool to protect battery health when plugged in for days at a time--Lenovo (Thinkpad series), Dell XPS/G series, Alienware and Acer have charging limits so the battery will need to be drained to 80% before it fully charges and counts as a charge cycle.
Yes, you absolutely can run off of DC power. Google DC-DC ATX power supply units. Here is an example. DC power supply units are not common, but are often used with computers connected directly to battery backups and areas where connection to the AC power grid is not available, such as boats.
Most of the times the laptop battery is fully charged and plugged in. is there a setting I can enable to use only direct power when plugged in and battery fully charged? This is to try and protect the battery from overcharging and heating. 01-16-2024 02:20 PM Hello. There is no such setting.
In my experience every laptop may it be an ultrabook or workstation/gaming model relies upon the battery as some OEMs draw more peak power usage from the battery. Some PC makers do a firmware level restriction if you unplug the battery, the processor will be throttled to 400-800Mhz.
As the voltage drops, probably around 90% of the supply voltage, a setting is triggered that tells the power system external power is gone. In less than a few thousandths of a second, it tells a transistor somewhere to connect the battery, and life goes on.
I don't think any gaming laptop can run at full power while on battery, you need to be plugged in to fully use the components. The laptop doesn't run in its full potential while unplugged, so as to the battery from damage. As someone already said a battery can deliver limited voltage only.
