Yoga S740-14IIL (81RS) : No standby when connected to compatible Lenovo dock (40AN)

2020-04-20, 6:33 AM

Hi,

 

 

When putting into standby (using Windows 10 start menu) my closed Yoga S740 (81RS) connected to Thinkpad Thunderbolt 3 Dock Gen 2 and external monitor, the laptop battery indicator blinks blank about 3 seconds and then comes back to solid blank. The external monitor stays in standby and I cannot wake it up anymore unless disconnecting/reconnecting the dock. Both laptop and dock are fully compatible according to https://accessorysmartfind.lenovo.com/#/products/40AN0135EU

 

Hopefully this will be investigated and corrected because, for now, using same brand laptop and dock is as useless as using different brands (no compatibility in fact).

USB-C/TB3/Power management is plainly wrong on this laptop! At least when used with external TB3 dock (compatible Lenovo model).

 

Sometimes, it's stuck on post Lenovo logo when rebooting, sometimes the second monitor is "blurry" when disconnecting/reconnecting the dock, sometimes when you disconnect it from the dock put it in standby using Windows menu, it wakes up as soon as you close the lid... Unbelievable! HP laptop connected on the same dock is perfect!

 

Once powered on, using this laptop is great but then, DO NOT PLAY WITH THE POWER BUTTON/MENU/LID if it's connected on the dock.

 

Lenovo has to fix this. It's an expensive latop/dock setup.

Yoga S740-14IIL (81RS) : Wife drop outs

My Yoga constantly drops wifi connection. It is the only device in my home that does so. Any suggestions on a fix.
