Dell has acknowledged that some of its laptops give a “tingling sensation” to users when plugging in cables or accessories—but insisted the “voltage does not present any risk of injury.” Complaints about the surprise jolts have been trickling in about a few different models for the past year, Techworld reports. Dell simply recommends unplugging AC adapters before attaching peripherals.
The "tingling” Dells have raised concern because of previous incidents of batteries catching on fire; the company recalled 4.1 million of them in 2006. Using grounded power adapters (plugs with three prongs) solves the shock problem, but Dell has no plans yet to send users replacements for their current ungrounded adapters. For the time being, the company suggests, keep your hands dry and don’t compute barefoot.
