Windows 10: I started my Lenovo Legion 5 15ACH6H and it has a blackscreen

Yesterday after coming from a friends house I had my laptop on my backpack and I left it on my backpack till the next day where I tried to start my laptop but it did turn on just it had a blackscreen and the keyboard was not working. In my friends house we just did a clean up of the ventilation of the laptop and after the clean up it was working just fine. Why is this happening and any help?

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.

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 5 15ach6h bsod whea_uncorrectable_error

hello
my laptop, Lenovo legion, has been having random BSOD error code: whea_uncorrectable_error.

i upgraded the bios and downgrade it, but i still have the same problem, mostly when it's unplugged.

so far, a reinstalled Windows made sure every drive and window is up-to-date, and it still happens.
also, i checked every resource including Lenovo database on how to correct this problem and used intel tools whit no result
I tried the memory test tools and the Lenovo tools, but no error is detected. all software and apps used on my laptop are all legally purchased. no pirated or cracked version is used.
i added an image of a memory dump file with this post for further information
thank you in advance

edit: i just need a confirmation this is a hardware issue
