I have two of these and have had them for several years. Lately one of them has begun to stall in trying to power up when it has been put in low power mode by Windows. I noticed there are some parts available for these, but I'm not sure what part I might need. Anyone know? Thanks for any help. edit: I found among the parts being sold are replacement capacitors. Soldering in some new caps is not a daunting task for me, and they are cheap. Does this seem a likely fix?
