Complements of babelfish: .. Correction, I found a component which heats, ullages! It is component the mic256, " Dual Slot PCMCIA/CardBus Power Controler ", but the datasheet gives 125C like operating temperature... A high temperature thus has the air normal. By cooling the chips with a metal strip posed on the case, I obtain operation lives a little longer, but however, the other face of the chips (side pcb, it is to say) remains hot. I have the impression that the problem comes from there. The mic236 has a thermal protection which starts. Why that does it overheat? Mystery... Perhaps that the catch from Jumptec will be able to say some to me more. .. -Chris -- Subscription/unsubscription/info requests: send e-mail with subject of "subscribe", "unsubscribe", or "info" toWear-Hard Mailing List Archive (searchable): http://wearables.blu.org please, Please, *PLEASE* don't subscribe through a forward/false domain
