Looking on the system I realized that even though I deactivated both mouse and keyboard to awake the computer on sleep
When I put the pc to sleep manually, it still responds to both of them.

Therefore Im not sure if we can trust it's not awaked with the lid closed.

Also I heard mine awaking the HDD making very low sound and stopping seconds after randomly when it's supposed to sleep.

I applied all the tips of the battery forum, I'm just curious to know if this both things happen to someone else
