I bought a Sony Vaio laptop - model no. VGN-CR 490 - seial no. 3000480 - made is USA from a dealer in Hanoi in Vietnam before 3 weeks. On receipt of the laptop, I felt mild shocks through power leak on the metal frame of the laptop. Tested with a power tester and took photogaphs of the red indication on the tester to confirm power leak and asked supplier to replace. The supplier refused to accept my claim for replacement and retainined my laptop for testing by SONY Vietnam - another authorised dealer for nearly 2 weeks. After testing the dealer issued a letter stating that all the laptops of CR model have such leak which has effective DC voltage of 19V inducing a voltage of AC 75 V as leak which causes the shock. The statement further indicates that the leakage does not cause any harm to human health and if there is any loss to human life caused by the notebook the dealer is legally responsible for the pledge. I lodged complaint in web site of Sony - Asia Pacific - attaching photographs taken but no response from SONY. I wish to know if anyone experienced similar complaints and also is there a way to take up this issue directly with SONY - USA or Japan for replacement of the laptop.
