I have bought this laptop since 2 months and unfortunately have had to put to repair 3 times already for motherboard getting malfunctioned. Looks like reverse current issue. The Dell repair center at Regenerisis(nalstop, pune) has not been able to fix it. So trying another authorised service center. The only good part is all repairs are at zero cost as its in 2 year warranty. However, I would have prefered a non defective piece instead. Fingers crossed and looking forward to getting it fixed for good. Will provide my next update after the usage after few more months.
