BTW - I also started late in the IT business (full time in 1977, though I was programming 10 years before that) - my experience before that was all electronics. Multilayer boards are no fun. Sometimes a board only should be repaired with a professional brandet hot air soldering station. To notice at what point you need unpayable expensive soldering tools, before you damage something, needs experiences. Usually you can use a good soldering iron or at least conventional professional brandet soldering and unsoldering stations. Since this is an open mailing list, we IMO should point out to be careful. If there should be a crack in a conductor path, somebody who knows how to solder, even without much experience, usually is able to fix it with even an elCheapo soldering iron, but in some cases you e.g. can damage the connections of the vias, so it's important to be aware of this. I need reading glasses for some time past and I don't own professional glasses for soldering. A friend need reading glasses too, but he has got special professional glasses for soldering. Repairing modern boards sometimes needs special tools. Btw. I'm experienced in soldering, I did a lot of audio and video engineering in my life. I several times repaired sewing machines, laptops etc., while I always repaired the electronics, I very often damaged the casing and it sometimes needed days to mount the casing, after the electronic was repaired within some minutes. What I want to say is, that even if you have much experiences in doing something, there are some very common miscalculation. I know how to open many computer cases even without damaging a seal of warranty, but I don't know every plug made of plastic, inside every sewing machine. I encourage everybody to repair as much as possible by ourself and to encourage people does include to share experiences. 2 Cents, Ralf -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe.

If you are lucky your board has a built in post card. If not, you will have to buy one. They are nice to have around for such things. In case you are not familiar with post cards they have a numeric readout that ratchets up through the motherboards post process. The final number displayed can be looked up in a table that will tell you where and probably why the process failed. I would advise researching the post process on the net. If yours is built in ( like my intel i5-750 board) then instructions will be in your board manual. Intermittant problems are a bitch.

What happens if you shut it down completely; i.e. turn it right off so that even the LED on the MOBO is off? Thus fully isolating it from the electrical circuit. Surely, if the LED on the MOBO is on, electric power is till to some extent flowing, and the computer is still connected, live, to the electricity supply. It is therefore not completely immune to lightening strikes. So, if you are going to take these precautions, surely it is worth doing it properly, turning the computer fully off and then unplugging it? FWIW, I just plough on through thunderstorms.

The only thing that works is hot air from a hair dryer directed at the MOBO to the left side of the CPU after cooler for 30 seconds or so. I work in an environment characterized by high humidity; with respect to climate, Houston year-round is a tropical mosquito swamp. Five to seven years ago, I had a pair of ASUS motherboards, both of which eventually I scrapped due to a problem of the nature which you describe. Sometimes the boards would power up; other times they would not power up. When the boards were returned to the vendor (which is in a drier climate), the problem disappeared. It would appear that moisture is condensing on the motherboard -- or more likely, is being absorbed by the motherboard -- so as to provide a conductive path between two terminals or component leads. Even a slight lowering of the resistance of the motherboard substrate can cause trouble. Also, if components have been soldered in by hand at some point in the manufacturing process, check carefully for rosin bridges, which also can be hygroscopic and conductive, even if perfectly translucent. Rosin is brittle, and can be removed by scraping with a metal probe. Be ware of solvents, for some solvents can damage components such as capacitors. Application of a non-conductive water barrier to the troublesome region of the motherboard might solve the problem, if you first get the board really dry. A silicone spray made to waterproof shoes or fabrics might work, but only if it dries to a non-conductive state. To get the board really dry (so that trapped moisture is not released under the moisture barrier), you could bake the board for a day or two in a home-brew oven using the hair dryer or an incandescent lamp and a circulating fan, but then you need to monitor carefully the temperature so as not to exceed the factory rating for storage operating temperature. Capacitors in particular can be damaged by elevated temperature. Populated circuit boards of the highest quality (such as military grade) often are protected by a conformal coating; this is similar to the way power transformers are dipped in resin and then baked. And there are silicone-like potting compounds which can be applied, so that a circuit board and its components appear to be encapsulated in a block of firm gelatin.

Inspect the suspicious area of the MOBO carefully with a magnifying glass and then fix the crack or bad solder joint. The problem is that motherboards today typically are multi-layer laminates; if there is a broken trace on an inner layer, the break is not visible. But you bring up another possibility: the absorption of moisture may cause the motherboard to swell; this, together with an mounting screw which has been torqued a little too much, can cause conduction of current between traces within the laminate. When torquing motherboard mounting screws, use a jeweler's screwdriver (which typically has a barrel about 1/4 to 3/8 inch (5 to 10 mm) in diameter, and hold the screwdriver with your bare fingers. But do not leave the screws loose; they need to be set firmly -- else a screw may vibrate loose and cause an electrical short circuit. If you use a workman's screwdriver with a large handle or an electric screwdriver, you likely shall crush the motherboard beyond repair.

I would look them over very carefully. If you determine it is the bad cap problem then you would probably be able to replace the bad caps.

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. RH -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe. Trouble?

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 -- Forwarded message -- From: Russell L.

Rather than simply tossing the supply into the dumpster, I sawed open the case.

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. RH -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe. Trouble?
