Battery power being cut way too hard
Battery power being cut way too hard
Hi everyone. While my laptop is connected to the AC adapter, my dGPU is limited to 50 watts and my CPU goes up to 80 watts momentarily and 45-50 watts under sustained load; And both of these are normal according to specs. Going forward, when it's not connected to the AC, the dGPU is imited to 30 Watts and CPU to 25-30 Watts under sustained load (if I test CPU and dGPU separately). My problem was, and is, when the dGPU is under load and consumes 30 Watts stably, if my CPU power consumption goes beyond 12 Watts, the dGPU massively throttles, going from 30 Watts to 8, and it's memory clock going from 5000MHz to 405MHz, basically rendering it unusable, and this situation goes on for 4-6 seconds; At the same time, CPU can be seen throttling, say for example, suddenly dropping from 25 Watts to 8. But as I said, if I limit the CPU power to 12 Watts, nothing would throttle, but performance is garbage anyway because of CPU power being so low. I know that laptops perform inferior while on battery, but come on, I don't think they can't provide more than 42 Watts combined, right? So I think it's a power delivery problem, as I troubleshooted NVIDIA drivers and that's not the issue. I even tested Linux drivers and still the same thing happens. Thanks for any help in advance.

Actually gaming laptops come with about 45 to 50 watt-hours of battery life. So this looks like it matches up in the specs. Is it easy to find or replace? EDIT: I found a link here: https://www.msibatterystore.com/msi-batt...cement.htm This specific laptop has a 54 watt-hours battery, but that number isn't exact. You lose some power when you convert it, so the real usable power is actually around 45 watt-hours.
I don't think how much juice a battery has matters when it comes to speed. If you take 45Wh and use it up all at once, you get one hour of work. But if you try to dump 90W right away, that same battery only lasts 30 minutes. So, what really limits power is how good the tech inside is, not just the size. Basically, batteries of the same type should be able to give out their max power no matter how full they are.
