Now, however, the major shortcoming of this castle: In the product description is a cable length of 1.8 m. This would be roughly the cable from the heater etc. halved since even back to the laptop back must -> remain 90cm, which is not the world, but is now pretty much standard in locks. This cable here is so strongly coiled it up with incredible force draws back together as soon as it is stretched longer than 50cm (25cm so from the heater).
I have no Ultrabook but a DellXPS battery is a 9-cell for a modern laptop really extremely heavy, others are likely much earlier the problem that your laptop have become self-employed.
Since I can not always rely on me that I find in 30cm near an object to connect I have to lock unfortunately send back, maybe it will always connect to the same place but someone else I can not recommend it unfortunately
