 Posted: Fri Apr 03, 2020 6:53 pm Post subject: That time when a component exploded... our stories |
 |
|
I have time, thanks to Mr. Covid, to test my motherboards.
Some are dead (but I'll investigate in a future time), most got a Bios flash, others had some component die.
Just tonight I had 3 caps exploding. Nice!! 
One just went "poof", but the board kept going. I pulled the plug.
Another had 2 caps explode in sequence like geysers: WOW!
The last one got me perplexed as it made a noise, saw some liquid boil on top of the cap and that was it.
Tell you stories now!!! Boredom looms and the end ain't nigh... |

"And I thought I had it hard..." has meaning now.
I really hope more stories come in.
One time I fried a mobo inverting P8/P9, black wire at the corners  Late at night never again. |

Back in the day when CD-ROM manufacturers were racing to have the highest "x" rating on their drives - even at the cost of real performance, my boss decided to order in some no-name brand 80x drives so we could have "faster" dirves than the 52-68x ones sold by our competitors.
It wasn't long before we started getting faulty units back, but not for the usual reasons. You see, these drives spun so fast, that even a tiny sticker in the disk would cause them to become unbalanced, warp, and shatter inside the drive. And I don't mean crack - they would break into 20+ small sharp pieces. It was a slot loading drive, and we once had a disk shatter in a machine I was testing in the store.
It broke with a mighty bang, and fortunately I'd left it to install something and gone to do something else because when I got back I found pieces of polycarbonate had flown out the slot and across the room.
After that, the boss switched exclusively to 52x drives. |

I had a Precision M6500 motherboard burn out on me, not spectularly though.
Another turbo retarded thing I did: I sold a EpoX Socket A board and I fucked it up five minutes after receiving the money for it by inserting a RAM module the wrong way in, blowing up one of the memory VRMs. Ended up giving the buyer part of the money back and gave him the board because he wanted it anyway, if he ever fixed it: idk! |

Forgot to mention my 486.
Inserted the wrong way (orientation), powered on, heard a bang.
Removed the cpu, one pin broke but the cpu was still working and works to this day.
I never checked if the pin has a significant role or is just another ground pin. |

I had a 5.25" IBM ESDI hard drive go up in flames.
I kept the board since it had some nice ceramic Intel EEPROMs on it.

Maybe not vintage... but I blew up an HP XW6600's PSU once. I got 1 post out of a dual CPU setup (Another one had a bad PSU, but no bang). Dusted it out... and next time I plugged it in, it went BANG. Tore it down, and sure enough, a big black mark on one of the PCB's.
So if you have one of these towers... think hard about a new PSU. |

Back in the day, I did a lot of work dealing with POS
(point of sale) systems. They were all normally SFF
(small form factor) and Tier 1 manufactured products.
One in particular stands out to me very distinctly as
I am certain that the testing of them has shortened
my life span considerably.
The infamous HP DC5000 SFF PC. I had a large customer
base that used these PC's in their POS platforms. They
had exploding (and I mean exploding) power supplies
that when plugged in, the defective ones when turned
on would give off a LOUD BANG and start smoking. Scared
the dickens out of me on more than one occasion. Especially
when you had an order to deliver a 100 of them at a time.
You never know how many would explode when turned on. 
I finally learned to use a long extension cord to mitigate
the fear factor when pushing the power on button while standing
in front of these wretched PC's. I would plug up the PC to
be tested to an extension cord and then turn on the power
remotely from across the room.  |

Heard nothing, but I broke some days ago my Chinese LGA1156 motherboard when trying to test a Q1KY...
Completely forgot that itwas a LGA1160 chip...
It was switching on for 2 sec then off for 2-3 sec then on...etc. Until I cut the power. After that, I've never managed to switch it on again... Pity is that it was not the latest chip to test...

As a rule of thumb I stopped testing things when I'm tired because of the many "incidents" I had.
I so feel your pain |

Another couple of caps went "pffffffff" on me.
Motherboard still works though.
I know I'm going to leave a whole bunch of money buying new caps. |

For my vintage motherboards I use used caps desoldered from other dead motherboards very often. Of course before I solder them I check in capacity meter. There are many old solid caps are everlasting
New ones for modern hardware and for other people I use new ones purchased for example on Aliexpress.
