Framework Laptop 13 Ryzen 7040 BIOS 3.07 Release BETA

Hopefully I misunderstood, because that seems far from ideal. If the machine is plugged in, the battery should just sit unused (not charging, not discharging), the power needed to run the machine coming from AC power, unless power draw exceeds the capacity of the charger of course.

The laptop doesn’t seem to fully support bypass charging, while gaming (or doing demanding tasks) the battery cycles between charging and discharging and the battery level fluctuates ±1%, even when the power draw is only 48W

61Wh battery lifetime extender functionality and warranty

I’m going to take a stab at it and guess that’s not the full story. There’s likely(?) an additional compounding issue with the FL13 having a battery charge / discharge flip-flopping behaviour when the laptop (processor, more specifically) is under repeated high load. e.g. [TRACKING] Battery flipping between charging and discharging / Draws from battery even on AC That’s been a requested feature since 2021…and has been ignored we have yet to see anything reagarding it since then.

I’m actually curious about the bus voltage or the mainboard voltage of the laptop, is it 19V~20V or somewhere else?

Why is "19.5V" used as a common laptop charger voltage? - Page 1

Since the bus voltage is related to circuitry USBC->bus->battery->bus->USB&vrms&5V&3.3V… or just USBC ->battery ->vrms

BTW, where are northbridge, southbridge and what are the voltages of these components?
