Lenovo laptops are made from cheap plastic that crack during normal use - typing. My laptop that has only been placed on a soft surface, never dropped (not even rattled) has 4 cracks. Lenovo refuse to show interest and say it is caused by the consumer. That laptop is less than a year old. The laptop crashes daily and has done since the day I received it. Lenovo said this is not covered by their warranty. Don't waste your money.
