This might be useful when your machine shuts down unexpectadly under heavy loads: https://github.com/FlyGoat/RyzenAdj

For me it only happens in Windows when the batery is charging too. I think charging thresholds are a must. In linux we have tlp: https://linrunner.de/tlp/ and https://wiki.archlinux.org/index.php/TLP and https://github.com/linrunner/TLP :-D

Enable SMART on Old External Seagate SSD Ubuntu 20.10

Submitted by Greg Nowak on 2021-02-05

I have an old external seagate ssd 2TB for backup called "BUP Slim BL". It was a challenge to enable the SMART capability on Ubuntu 20.10.

You might give this a go: sudo smartctl -d sat -T permissive --smart=on /dev/sda1

If that does not work, you might need:

echo options usb-storage quirks=$(lsusb | awk '/Seagate/ {print $6}'):u | sudo tee -a /etc/modprobe.d/ignore_uas.conf
sudo update-initramfs -u

Lenovo G580 Notes

The screen started flickering and the quick fix is to push down just above the keyboard in the middle and then the flickering stops. Looks like a loose connection of the cable connecting the screen with the motherboard.

Lenovo T450s Thinkpad Screen Connectivity Issues

Submitted by Greg Nowak on 2018-12-11

Recently I am experiencing bad connectivity on my LCD-screen. It seems to happen randomly and periodically. The connection is disrupted and a gray darkish void appears on the screen. Sometimes this can be ammended by moving the screen up and down but the bulletproof solution is to suspend the laptop and wake it up again, then the screen works properly. Sometimes for hours sometimes only for minutes. Last time I managed to remove and reattach the left hand side LCD-connector from the motherboard. This releived the problem for a couple of days, but now it's back again.
