I have a razer blade 15 advanced 2022 connected to a thunderbolt 4 dock (dell wd22tb4, although tested with other tb4 docks). I use the device in a closed state connected to the dock and the included 240watt power adapter. Unfortunately, no device connected to the dock is able to wake the system from sleep. This includes both modern sleep S0 and legacy S3. This includes a wireless logitech mouse, a wired keyboard and a USB NIC configured for wake on lan. I can confirm that when connected directly to the USB ports on the blade all these devices are able to wake the laptop from sleep. Additionally I can confirm the dock does indeed stay powered on as I can see the network card blinking active, but still not waking the machine. Some laptops offer a BIOS setting for “wake on thunderbolt”, the blade does not however, is this feature not supported?
