Chip giant Intel has now confirmed there was a problem with some mobile parts but said the problem was in the substrate and not the silicon. (Story: Tosh, Panasonic recall Intel notebooks). A UK representative said: "It wasn't a silicon issue, it was a substrate packaging issue with one of our suppliers. It is, by no means, a recall." The problem is restricted to a relatively small batch of parts, he said, although he did not say how many were affected. He said he was unable to say which geographies were affected by the problem. Intel in Japan originally issued the warning. If customers have problems booting mobiles, he said they should call their local notebook supplier for help. ®
