For $0.00 cost (the moulding was in my wook scrap bin), it gives me the proper keyboard angle and decent airflow. I recently installed a new fan (installing a fan in this unit is HARD it is the first thing in the case, meaning you have to take EVERYTHING out to get to the old fan to install a new one) and I blast the air passages regularly. Did this just last friday. It COULD be that the temp went up a degree and it was enough to trigger the shutdown. I was wondering more if it is a problem with the ACPI in terms of reading the CPU temp. Isn't there a file in /proc with this information? Maybe I can have a process that watches it and writes a log entry everytime it changes? > There are several laptop manufactures that are stupid and place the air > intake or visa versa at the bottom of their laptops.
