Leaky Capacitors and Computer Instability

Monday, July 7th, 2008

Some time back I did an article here about leaky capacitors and linked to some really great photos of a “healthy” mainboard capacitor and “bulging” capacitors. The long-story short version is this… Once upon a time there was some corporate espionage among capacitor manufacturers. Someone had a really good electrolyte formula (the goo inside a [...]

Reinventing the capacitor

Friday, June 9th, 2006

These days, big inventions aren’t entirely new creations, but improvements on an old idea. This latest in a string of interesting science/technology breakthrough stories is about just that. Researchers at MIT (how many sentences have I started like that this week?) have developed a new way of constructing a capacitor. One of the limiting factors [...]

Sometimes the simplest things solve problems….

Tuesday, January 17th, 2006

How many times have I had this kind of phone call…. “my computers not working”… “the light on the monitor is on, but there aren’t any lights on the keyboard. everything seems connected, but there’s nothing on the screen.” Usually, my first question is along the lines of… “have you tried turning it off and [...]

Basic Hardware troubleshooting

Friday, January 6th, 2006

Sometimes machines stop working, or you install a new piece of hardware and just can’t boot again. That’s when you have to get back to some basics to troubleshoot what the problem is. Yesterday I saw a machine that wasn’t booting. It would display the splash screen and then power down. They had a new [...]

Bad capacitors causing strange system behavior

Thursday, November 10th, 2005

This is, in fact something I’ve been getting ready to do an article on soon. I had a system that had very strange and random problems that I’ve visited and tried many of the typical fixes for, in fact I think I saw it a couple times a week and either couldn’t reproduce the errors [...]
