<div dir="ltr"><div class="gmail_default" style="font-size:large">Mark and All, When I hear "the laptops I lend them have started not working," I have to ask the user several questions. "not working" usually means it won't do what I want, when I want and how I want. It can be a variety of things and nothing at all. It may be that some cache or memory allowance has been exceeded, which may be very specific to the "what I want" part of things. When I encounter this situation I try to get more information about the circumstances and details. Who knows, maybe one cannot be playing Fortnite and while compiling code? Just a thought. Thanks, Ted P<br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Sat, May 8, 2021 at 12:44 PM Mark Galassi <<a href="mailto:mark@galassi.org">mark@galassi.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><br>
I sometimes get reports from my students that the laptops I lend them have started not working. When I get them back I boot them and they seem to be OK.<br>
<br>
I have gone and run the classic unix "crashme" program to stress them with load and threads and memory access, but they go along nicely.<br>
<br>
I wonder if anyone has a favorite program to stress the system, disk, display, memory, CPU, ... Display seems important: sometimes the problems I've seen had to do with the video drivers trying to use advanced hardware features that are not well supported.<br>
