There are a lot of Strange things about these machines!!
Initial release was fun with probably the worst being a BIOS issue where some folks were experiencing very long boots. When I say very long I mean like upwards of a minute or more, not the mammy whiners complaining over a few seconds. Whaaaaahhh, my friends Acer boots in 9 seconds and this is taking 12! I got so sick of that one that I got in trouble here for scolding them.
My philosophy, if it aint broke dont fix it.
Weve seen a lot posting over heat issues just to find it was sitting on a bed restricting air flow.
When these fans crap you will know! Either they quit and one fan goes to running full bore all the time or they make a very loud screeching or crunchy sound from bearing failure.
Other than that.....run it like you stole it!!
