Actually very good if not:

Unfortunately, still occurred defects which have then but prompted me for a replacement, return it and me to refund the purchase price.

Here Lenovo seems to have not been able to keep the quality at a steady level.

The following problems were encountered both in the first, and in the replacement:

1. rattling at irregular intervals touchpad.

- Always seems to occur when work is frequently performed with this.

2. the fan bearings seem consistently to have a problem.

- This is indicated by a rattling sound at certain speeds

3. When the battery is fully charged and the ultrabook remains on the network, is a high-frequency sound coming from network
Connection to hear.

- The plug is removed, the sound is gone.

These 3 problems were the reason to return this but to be very well-equipped ultrabook again for me.

Schade Lenovo.
