No suggestions but want to say nice laptop. They also seem to be popular being they're currently unavailable

That said my only suggestion would be to take time to learn the laptop yourself.

Lenovo Legion 5 wakes from Sleep even after disabling waking

My Lenovo Legion 5 (82AU00BVUS) keeps waking from sleep, even though I've taken all sorts of steps to prevent it. WinVer: 20H2 (19042.867)

System bios info:
SMBIOSBIOSVersion
EFCN38WW

Here's what I've done so far:

1. Disable wake timers

I completely disabled wake timers in Power Options:





2. Checked wake_armed devices

I checked which devices are "wake_armed" in powercfg. Armed devices include the keyboard, and the ethernet port of an external dock, which is strange because when I look in device manager at that ethernet port, the enable wake is disabled, so something isn't adding up right.





3. Check Device Manager

In Device Manager, I checked on the eXtensible Host Controller that you see mentioned above as the cause of the last wake event. There's only one such controller:





And the device properties:





As you can see, according to device manager properties, the device isn't allowed to wake up the computer - and yet it did.

And remember how it said that the Plugable ethernet was wake_armed? Well check this out:





4. Check Event Viewer

Event viewer confirms the eXtensible host controller as the cause of the wake event:

The system has returned from a low power state.

Sleep Time: ‎2021‎-‎03‎-‎25T21:37:43.268198000Z
Wake Time: ‎2021‎-‎03‎-‎25T22:46:01.919720100Z

Wake Source: Device -Intel(R) USB 3.1 eXtensible Host Controller - 1.10 (Microsoft)
Summary

1. In power settings, wake from sleep is disabled entirely.
2. The system is being woke by a device that, in device manager, shows isn't even allowed to wake up the computer.
3. Another device (plugable ethernet) shows in powercfg that it is wake_armed, even though its power configuration in device manager says the opposite.

Something crazy is going on here. How do I stop this computer from waking up?

 

Lenovo legion Y540 Keyboard not working after windows 11 recent update

I have a lenovo legion Y540. I have been using windows 11 for the past 2 months, couple of days back system installed some new updates for windows 11 overnight post that laptop's inbuilt keyboard has stopped working but the keyboard is working in BIOS and external keyboard via USB is also working just fine.

I already tried usual solutions to update drive which always say's that driver is updated . I tried troubleshooting which also did not find anything.

I don't suspect any hardware issue because the keyboard works fine in BIOS.

Any suggestions ??
