I have had this laptop for just more than a year and never faced any problem with it until sometime back when I got a "tingling sensation" using the track pad, just around the edges. That happens only when running on AC.
When I Googled I see there seems to be a problem with this laptop. However, many posts in different forums talk about two pinned adapter as a probable cause but I have a three pinned one. The wall outlet is earth grounded properly.
Since I never had this problem, is this about faulty hardware or other environmental factors? It had been a hot day and the night is cold (but it has been so mostly this season), also I have scrapped my fingers around the nails lightly (just thinly peeled off skin) doing gardening.
I just want to know what's happening, as I cannot call the customer care till Monday. Any clues?
The harder I press the track pad, the more the sensation.
I got it again, even when running on battery but with the adapter chord plugged in and AC off! I unplugged it and the shock was gone. I plugged it back in and the shock didn't return! Its funny. I am not even able to see a pattern.
