Executive 14 BIOS update

Hello, I wrote to the support about 4 month ago (we started the 8/5/2024) about the issue that laptop is having while on battery.

So everyone knows (since reviewer does not do their homework..):

When charging the laptop with its charger

- In silent mode the EC give 15W of max TDP to the CPU

- In normal mode the EC give 40W of max TDP to the CPU


When charging with USB-C of 100W or 65W capacity:

- In silent mode the EC give 15W of max TDP to the CPU

- In normal mode the EC give 25W of max TDP to the CPU

But on battery,

- In silent mode OR in normal mode the EC give 40W of max TDP to the CPU.

Its not normal for this tiny laptop to draw 40W, regarding the operation mode when on battery. So please, fix the bios for your customers (those wo already paid and are waiting for "support").

As a customer, you  can monitor your laptop power draw in different mode while using intel-undervolt to measure the power consumption of your CPU (AC Power, Battery, USB-C powered, activating and deactivating silent mode).

type sudo intel-undervolt measure in a terminal, it will ask your password and show the power draw in real time. You will be surprised.

Hello Romain,  

I understand your frustration regarding this matter. It has indeed been a while, but due to certain circumstances, we haven’t been able to release the update yet.  

I assure you that I am in ongoing discussions with the development team to expedite the update and address this "issue." I put it in quotes because it is not currently classified as a high-priority matter, and here are the reasons:  

1. The CPU stress test you are conducting displays the TDP, which means you are practically using the maximum performance allowed by the TDP limitation.  
2. This does NOT mean that the CPU is consuming that amount of energy under normal conditions, such as browsing or watching videos.  
3. When the charger is connected, there are different operating modes, but in battery mode, there is only one. However, this is dynamic; the TDP may vary depending on the battery percentage:  

   - 40%~100%: 32W  
   - 15%~40%: 28W  
   - 0%~15%: 10W  

The reason for not implementing multiple operating modes in battery mode is related to battery degradation over time (which is inevitable and happens to all batteries). As the battery degrades, it may no longer sustain the same voltage as when it had zero charge cycles. For instance, if the "normal" operating mode requires 40W and the battery is at 20%, it might fail to maintain the voltage and cause a sudden shutdown.  

That said, as I mentioned earlier, we are working on an update that will include different operating modes, even in battery mode.

We will notify you as soon as the update is ready. In the meantime, we kindly ask for your patience.  

Best regards,
