I bought this laptop ’Dell Vostro 1540’ three years back and still it’s giving a good performance. This laptop is moderately powerful and relatively inexpensive system for businesses and home users alike.The screen itself is relatively easy to twist, and squeaks when twisted. The keyboard and touchpad both are very sturdy and without flex. When it comes to the battery back up, I managed to squeeze 3 hours 30 minutes out of the battery before it abruptly went into standby. Despite some design flaws this Computer is still an excellent machine.
