Hi, I installed Ubuntu MATE 16.04.01 LTS on a netbook, Acer Aspire ONE D150-1 Bk and I have two issues:
- when I turn off my netbook, the netbook doesn’t turn off, but it goes to standby mode, so 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 … This wording is a result of a “fsck”?, … can be reconnected 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 " and when i press the ON button, my PC goes OFF normally,… but why the PC behaves this way?..what’s the problem?
- 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 comand: " 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
