Bought 2 laptops directly from DELL. Didn't know there were manufacturing defects after 9 months of frustrated usage. What a disappointment the total lack of quality control at Dell factory in Penang. Dell changed 2 hard-drives for me; but one month later, the batteries faculty. One problem after another. It's so grating. Dell doesn't understand how to handle my case. Now my warranty expired and I have no recourse. So I appealed to Dell to give me 2 new sets as replacements. To be fair, Dell should offer 2 new sets of laptops as replacement for me. They refused. Now my warranty is out; and my family is about to throw away the Dell laptops. Sorry, I will never use DELL for the rest of my life.
