My Tab shutdowns before the warrenty period hence I visited to lenovo service station, there is a guy said me problem with the battery hence and it should be replaced, and he said come after 2 days but after 2 days when I went he said battery is not reached to his service center and he says come tommorow, than I dicided tontake some delay and I went after 3 days and he resended the battery to lenovo manufactureres, so I come at home and used that defective product about 15 days and my warrenty also expired between that 15 days , after a month tab completely shuts down and I go to same station and he said problem with motherboard and it should be replaced and he taken 3800/- , what a great cheating they does.
