Re: [PLUG] OT dell laptop repair

[Matt Murphy <mattyhead@gmail.com>]

Same thing happened to me with my now-ancient XPS M-1210.  However,
since I toenailed dellfand (source is out there -- it's C code for fan
control on a large swath of dell laptops) in as a service, this hasn't
been a problem (if hybernate/sleep is incomplete, it keeps pushing
what air is there around, thus somewhat saving my bacon.  Of course, I
have spare fans already for the inevitable burnout due to increased
use).
