The slight tingling sensation discussed herein has been present in the electronics industry for numerous years and is common on notebook PC products and other electrical devices and appliances that utilize metal surfaces and 2-prong ungrounded AC adapters. HP Notebook PC models include a

3-prong grounded AC adapter to help minimize the presence of slight tingling sensations as well as for compliance, safety, and reliability reasons that are mentioned herein. In addition, HP has made efforts to further reduce electric current leakage on typical notebook PC touch points such as the palm-rest area.

Warning

To ensure continued compliance with regulatory requirements, HP recommends that only HP-branded AC adapters, batteries, and other accessories be used with HP Notebook PC products. To reduce the risk of serious injury, read the Safety & Comfort Guide included with HP products and available at
