Have been using a Sculpt keyboard since around 2015. One thing that seems to alleviate the problems of missed keys and the keyboard going to sleep (at least on Windows): in the Device Manager, look for the connection dongle (it should be connected via the USB Root Hub) and edit its Power Management settings to disable "Allow the computer to turn off this device to save power."<p>I haven't had any issues with the laptop going to sleep when it's told with this setting enabled, and afaik battery life is unaffected (still haven't changed batteries in the keyboard after 3 years).<p>Regardless, I'll still be checking out this mod. I didn't even know this keyboard had LEDs in it.<p>Suggestions for Microsoft product developers if they ever read this or care:<p>1. Fn keys have <i>got</i> to be like the rest of the keys. Like other users here, I get F5 (which I use to <i>run code in Visual Studio</i>) stuck probably greater than 50% of the time.<p>2. Separate Fn key, or separate media keys. The switch is stupid, and I never use the non-Fn functions.<p>3. Take the calculator key off the main keyboard; it's a duplicate of the key on the numpad, <i>where it is actually useful</i>.<p>4. I'm ok with the backspace key on the numpad, but the top 3 keys should be regular keys, not microswitches.<p>5. Better power management and wake-from-sleep. This thing should <i>never</i> be dropping keystrokes. Ever. I'd trade battery life for this feature.<p>6. Make wired optional! Almost <i>everything</i> has a charger these days...why am I given alkaline batteries for this? This also potentially opens up the gamer market, given the latency reduction shown in this article.
