Are there any statistics or at least any anecdotal evidence that this is really a problem?
My regular notebook has over 1000 miles of dirt road travel on it and it's always running OziExplorer, i.e., accessing the disk. I know at least one other person with more miles on theirs.
My older notebook had even more miles on it. The hinges on that one gave up eventually.
Well it may not be his problem but that’s a very common problem. The disc spins. The heads bounce on it eventually you either destroy the disc surface or you destroy the heads. That usually shows itself as a sector error.
another killer is moisture causing oxidation on the boards and components.
Yet another problem is temperature cycling causing failures in the solder. Ideally electronics like to live in an environment where it is about 60-65 degrees and dry.
As an example...some idiot in my company decided that their would be big savings if the temperature in our Cell sites was raised to 75 degrees. Sounds harmless doesn't it and huge savings on electric allowing a 5-10 degree increase in temp of a unmanned building. Well that’s fine its 75 degrees at the wall now but the electronics were then running 90-100 degrees instead of 80-90. Amplifiers that had been running for years with no problems started dropping like flies. So at $1500 each on fixed rate repair on just that one unit and their may be as many as 6 in a big site how much did they end up saving? :xxrotflma
Sealing he main board is not hard. Its the processor and the hard drive making heat that need the airflow. The processor is actually and easy fix byt potting it and only having the heat sink and fan exposed. The hard drive is more complicated to seal and then you still have the issue of Vibration.
They are MUCH better then they use to be that’s for sure but there is still big room for improvement on some components.
