Problems with Ubuntu MATE 16.04.01 LTS and Acer Aspire ONE D150-1 Bk

Question

I installed Ubuntu MATE 16.04.01 LTS on a netbook, Acer Aspire ONE D150-1 Bk and I have two issues:

1) When I turn off my netbook, the netbook doesn't turn off, but it goes to standby mode. I need to press the ON button, the PC restarts and again click on the icon to turn off the PC, and my netbook goes OFF. Same thing when I turn it ON, I press the ON button, and after the bios message, the PC goes to standby mode, I need to press again the ON button and only after this procedure, the PC turns ON, so what's the problem?

I also noticed that when I turn off my PC, the screen goes all black and it appears only a line that says something like dev/sda1 clean, xxxxxx bytes, xxxx bytes something like this. Is this a result of a fsck?, Can it be connected to my problem?

For this problem I try this "fix":

• I try with a shutdown -h now command and the PC turns OFF normally;
• Also checked my power management settings in System -> Preferences -> Hardware -> Power Management and set all the options to Never or Do Nothing, but I have the same problem;
• In System -> Preferences -> Hardware -> Power Management -> General I set When press the ON button -> Turn OFF the PC. When I press the ON button, my PC goes OFF normally but why the PC behaves this way? What's the problem?

2) Sometimes when I turn on my PC the Wi-Fi card doesn't show any wireless network, so I need to open a terminal and issue the following command: sudo service network-manager restart. After this command, the Wi-Fi starts to work well, why I need to do this, why the Wi-Fi card sometimes doesn't show any wireless network?

For this Problem I try this "fix":

• Here is the output of the command sudo systemctl status network-manager, performed after switching on the PC and before restarting the service network-manager: https://thepb.in/p/76hErQzXPk1HV

I solved these problems by updating the BIOS of my netbook to the latest version.
