Hi everyone, newbie here.
I have a problem that has been occurring for one month now:
once or twice every other day, my laptop freezes, meaning that the screen starts flickering, and then the laptop reboots. The issue sometimes manifests itself by trying to boot several times, but failing. Sometimes I have to hard reboot after the screen freezes.
It usually happened when I tried to move the laptop from below, or when I moved the screen after some time.
This issue is 'scientifically' happening also when I am trying to train a machine learning model with FastText on a coprus of 230MB, indipendently from using 1 thread or the default settings. Three times out of three, after some time (usually around 20% of the training), the malevolent event happens.
I kept track of the CPU temperatures during the last training, with core-0 being at 65°C and core-1 at 57°C (never above 69°C).
My laptop is a Lenovo ideapad 310
Intel Core i5-7200U [email protected] x 4
12GB RAM
Intel HD Graphics 620 (Kaby Lake GT2) ---> I have also a dedicated NVIDIA GeForce 920M, 2GB
The laptop is 2-years old, the battery is not good (it probably lasts ~1 hour max), the charger is not the original Lenovo one, as it stopped working; I bought a KFD charger that suited the voltage.
I opened the laptop a couple of days ago to remove some dust from the case and the fan.
Dual boot with:
Windows 10
Ubuntu 18.04.3 LTS
98% of the time I use Ubuntu.
From /var/log/syslog, this is the last set of messages before I had to hard reboot:

Oct 2 16:14:56 MatteoLenovo systemd[1]: Starting Flush Journal to Persistent Storage...
It happened at 15:54.
Do you have any advice on such a matter? Can I post any other log?
Thank you very much for your time and your help
Cheers
