Thought I might offer this, even though I don't understand it, in case
anyone else has a similar issue.

If you use hibernate mode the machine completely powers itself time
after a user selected period of time. This minimizes dust ingestion.
The recovery time on our laptop is less than 15 seconds after touching
the power button.

HTH.

I experimented with both "sleep" and "hibernate" modes. Frankly, as far
as power usage is concerned, I don't see any difference.
In both, the display, hard drive and cooling fans stop operating.

The reason I started doing this is, as you pointed out, over time you
build up dust and the cooling becomes less effective.
This laptop is over 6 years old and I used to just leave it on 24/7. I
started shutting it down because I was concerned the cooling probably
wasn't as efficient as when it was new. But, so far, no problems.

How much dust ingestion are you going to get on a decently built laptop?

Now, a desktop, especially a homebrew desktop, is different. I just open
up the panels on mine and use canned air to blow the dust out every couple
of months.

Every laptop I've looked at have a grill over the area where the fan in
sucking in fresh air. What is decently built that is different from that
design?



I didn't say "no" dust would get in, I implied it would be minimal. I
was at the Apple store a few weeks ago and watched a tech replace a fan
in a Macbook pro. He said the laptop was about a year old. When he
removed all the screws and popped it open, I was amazed by how clean it
was inside. No visible dust, not even on the fan.
