  • Low 0-60 times are inherent to EVs. There's no transmission and the motor has a wide efficiency area. It's basically hard to make a non dual motor EV accelerate slowly. Single motor ones aren't quick, but you won't get AWD if that's a thing you desire.

  • The 5090 costing an arm and a leg is fine since it's the flagship. I just hope the 5080 isn't actually just half the cores of the 90 just like 40 series has been.

    I just hope anything less than the best of the best isn't an awful value like 40 series has been. And the 5090 costing 2k isn't gonna make 50% less cores on the $1k 5080 look like a better deal.

  • The power draw is being limited, but not because the CPU or GPU are running too hot (they'll be in the mid 80s or even 70s). It's when the power delivery parts (inside the laptop) get too hot to keep up and it can't keep up. You can override those with programs like throttlestop, but the battery will drop MUCH quicker. When it's hot the PL1 and PL2 drop to about 25 watts which is basically unusable on 11th gen i9, but it easily has the head room for 45-55 watts. GPU is largely unaffected which is weird. I've seen it get limited to around 60 watts, but the 3080 mobile below 80 watts is also awful.

    For monitoring power usage I use hwinfo 64 in windows, I'm not sure if the portable version would work.

  • P1 gen 4 with the i9 and rtx 3080. Pay close attention to the power levels under heavy load. It will drop massively under long term heavy loads to try to prevent the battery from discharging. My machine only takes in a little over 170 watts from the power supply, but with a laptop cooling pad it can easily sustain over that 170 watt mark. It doesn't happen instantly, it starts when the laptop is fully heat soaked (takes 30+ minutes with the cooling pad). You won't notice it until about an hour or two in, but once it starts it will start accelerating as the battery heats up. Shorter loads that the laptop is more designed for it handles it just fine. It's only when you push it for too long and too hard.

    Also whats the power consumption of the mobile 4090 like sitting on but idle? Random programs trigger my 3080 for no reason and that GPU draws about 20 watts minimum. I want to upgrade, but I'd lose vram if I got anything less than the 4090 and I don't know if I want all of that excess power draw when the system can barely benefit from it, and it makes using it as a laptop awful.

  • There's nothing wrong with the device, Lenovo has confirmed this, and both motherboards my laptop has had have the same "problem". This isn't my only machine like this either, 16" Intel MacBook Pros are also known to discharge under full load, but that's because they're limited to 100 watt USB C.

    There's a reason why those devices run at minimum clock speeds when their battery is sub 5%.

  • It even happens with power efficient devices. All Macbooks will run at their lowest clock speed with a dead/low battery (even my M1), My Thinkpad T14 with an ULV CPU and it's odd. It tries to limit total system power to around 25 watts, even though I have a 100 watt power supply connected. My theory is that since 30 watts is the lowest power supply it will run off of it's trying to keep that 5 watt buffer. Unfortunately that means my CPU runs at 800mhz doing anything but idling. Laptops with dGPUs often just wont work at all, or are so far limited they're unusable.

    Some older laptops like my Thinkpad X220 will run at 800mhz on a 65 watt charger, but on a 90 watt charger it will run at full speed. But unfortunately in the days of USB C that makes things a lot more difficult.
