"HP customers affected by this program will be eligible to receive a replacement AC power cord for each verified, recalled AC power cord at no cost," says HP. The power cables in question are marked 'LS-15', and although the recall is specific to the US and Canada, HP will exchange the cable globally.
A company rep made a post on the HP support forums detailing the issue. Apparently only the power cord poses a fiery threat to your system, while the adapter is A-okay. Approximately 5.57m units were sold in the USA, with a further 446,000 flogged in Canada. The US Consumer Product Safety Commission says HP's received 29 reports of the cords 'overheating, melting, or charring'.
The US CPSC cites two claims of 'minor burns' and 13 claims of minor property damage in its recall report for the China-manufactured cables.
