Ubuntu 18.04.1 random crashes and slow cpu

I have a MEDION AKOYA S6217T MD99051 Laptop running Ubuntu 18.04.1.



My Problem is, that it randomly (seems like it) crashes. Sometimes a few minutes after reboot, sometimes long after. With crash I mean totally so no Terminal session possible and no sysrq.
In syslog I couldn't find any useful information, just /00/00/00... at the point of crash.
In addition to that my cpu runs not at maximum frequency, often at minimum frequency (500MHz) even in performance mode, but sometimes id runs at max freq. as it should. The cpu temperature seems to be ok at around 60°C.



Could there be any connection between these problems?



If you need me to, I can provide more system Info.



Here is a plot of cpu temp and MHz I recorded. Every five seconds a value was stored. The two dips in temperature were times I suspended my Laptop for a while and at resume it was cooled down.

  • If you mean upgrade from a lower Ubuntu version, no then it's a fresh install.

Title Spacing in Bjornstrup Chapter, Removing Chapter Number From Contents

Image
up vote 5 down vote favorite 2 I would like to make it so that the vertical space below the title of each chapter is the same when using the Bjornstrup package (i.e. so that the descenders do not affect the spacing - as shown by the red arrow in the picture below). I think I'm fairly happy with the spacing around "A chapter", so I'd really like titles without descenders (e.g. "Contents") to have the same vertical spacing as "A chapter" below the title. I would also like to remove the large "0" in the contents title. Any help appreciated, as always. documentclass[11pt,a4paper]{book} % Packages[![enter image description here][1]][1] usepackage[left=3.5cm, right=3.5cm, top=4.3cm, bottom=4.25cm]{geometry} usepackage[utf8]{inputenc} usepackage{libertine} usepackage[libertine]{newtx...
