Those who know me, unfortunately know I repair motherboards from time to time. I've replaced untold hundreds of bad caps. Some of them are actually "ok", not defective per se but the board design, system cooling or other variables (like overclocking or someone doing an upgrade unsuitable from a current perspective like running a 1.4GHz Tualatin Celeron on a generic '98 BX board) caused failure.
It was once thought the truely defective caps would fail merely by holding a charge, no ripple at all, but it's worse than that. I have a board I keep around as a reminder, it hasn't been hooked up for well over 18 months (is just sitting loose) and the cap swelling is still progressing. Funny thing is, that motherboard was one that had it's original caps fail, I'd replaced those caps a few years ago with some that weren't known defective at the time, and now many of the replacement caps are also swelling up and leaking.
If only it were generic caps, but some of the same brands that had problems are still used on new major-name boards today, albeit different cap family/models than previously, but then again for all we know they could've just changed the model name, put a different colored sleeve on them and that was the extent of the fix.
Lelon, (G-)Luxon, Tayeh, Jackcon, JPCON, Chhsi, GSC, Ost, et al. Fortunately most manufacturers aren't using these in high current areas anymore where the higher ESR->heat has the worst effect, but PCChips (and their relabels) still extensively use Ost where most manufacturers cutting fewer corners, wouldn't.
one thing the linked article has completely wrong, "If you are qualified to fix it yourself, Radio Shack sells the caps". Absolutely not, Radio Shack has nothing in the same ESR-zip-code as what is needed. The Panasonic FMs many of us use here will work though, among others.
