Re: [OT] Good quality hair dryer needed for Squeeze




Hi,
 
I am replying to all, not used to sitting in the dark with the light of the notebook to type only, Out here in the sticks there are always power failures when it rains. I normally use pop, not used to gmail., the mobo is two years old a midrange board with SATA 6 and USB 3.0, an ASUS, I also thought it was the Ocean air and humidity but my other ASUS mobo has no hassles. I have enough lightining protection to protect I dpn't know what and always unplug before storm, I think I was naughty when I fist received the board and overclocked it from 2.8 to 3.8 even though the temps where fine ans I have a fantastic Zalman aftercooler. devede ran quite stable a sdid prime sorry for the s[peeling my UPS is about to go flat

Was that only a decade ago?  I recall a number of front-page and cover
articles on the subject in "Electronic Engineering Times", "EDN", and
"Electronic Design".  And the problem involved some of the most
reputable motherboards of the day, including Tyan.

When I picked up the old-style (linear regulator) wall-mount power
supply of an ADSL modem, I heard a rattle inside, so I suspected that
the supply had become a fire hazard.

Rather than simply tossing the supply into the dumpster, I sawed open
the case.  Inside, I discovered a radial-lead (that is, parallel-lead)
electrolytic which had bulged on the bottom (at the rubber seal),
rather than tearing open at the score marks on top.  (The score marks
are not decorative; they are designed to act as a pressure-relief
mechanism.)

The pressure exerted by the bottom of the capacitor against the
circuit board caused the capacitor leads to pull out of the solder
globs on the circuit board, leaving a pair of open holes.  The rattle
was caused by the capacitor, which was loose inside the case.
