Windows 10: My laptop keeps pressing letter C lenovo legion 5 pro

Hi so recently my lenovo laptop has been randomly pressing the letter C on my keyboard whenever I try to search or type be it in settings or browser i can use my touchpad to move the mouse around but cant click with it as well. I tried updates, reinstalling drivers, using external keyboard I scanned with windows defender and used malwerebytes to see if it's any malware and it keeps happening so I tried to bring it back to factory setting but it got stuck on 64% for like 2 days went to the repair shop they factory reset it and said it should be fixed but it wasynt, now also my external mouse

:)

 

Lenovo Legion 5 15

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.

Enjoy *Smile

 

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?

 

It looks like my lenovo legion 5 pro has suddenly an underpowered GPU, and I can't figure out why

Hello,

Based on your description, since the model is marketed as a "gaming" laptop, it is likely that it requires specialized version of the GPU driver to work as advertised.

I recommend installing the version posted on the Lenovo support page, and see whether the issue persists.

If the issue still persists, since there are lots of OEM customization done to the hardware, I recommend contacting Lenovo support for further assistance.
