After I initiate power off/restart, system usually lead to a black screen as shown below or the basic Ubuntu logo screen
Then it freezes right on that screen or the display turns off yet the system keeps running. The hard drive and mother board active notification light remains on and within a few second of being frozen the CPU cooling fan speeds up.
I have to press the power button for 10 sec to shut it down. I have been facing this problem since I have installed Ubuntu 18.04.
I have tried couple of provided solution given in askubuntu but nothing worked(although didn't tried all due my limited knowledge)
I have tried grub edit method and I have tried
sudo shutdown -h nowand similar commands like it, nothing worked
you will see in the image I provided, there is something like "firmware update deamon[started]" so, I looked into the log for some bug related to firmware and found couple of them but to newbie to do something about them.
Also the OS freezes sometimes during regular task like Web browsing.
- processor-Intel® Pentium(R) CPU N3520 @ 2.16GHz × 4
- memory-2 GB
- graphics-Intel® Bay Trail
- OS type-64-bit
Laptops details- - Acer Aspire E-1 series Model-Z5WE3
Existing hardware problem-
- Battery is out of work
- Inbuilt keyboard have button pressed issue( currently floated with
xinput(I don't think this is the cause because I had this problem even before I floated the buit-in keyboard)
I think the freeze of OS during casual work and freeze during shut down are caused by same bug. Although OS freeze during casual work is rare.
Please help I am too Newbie to solve this problem by myself. I reinstalled Ubuntu but the problem is still here.
P.S- I installed Ubuntu 18.04 with a USB drive not by CD/DVD rom
