Apple withdraws a specific type of power adapter that has been in use for Mac machines (and some iOS devices) in recent years. Follow the link below to read more about this, and instructions for how to check whether you have an affected adapter. http://www.apple.com/no/support/ac-wallplug-adapter/
If you have one of the affected adapters you can bring it to the IT department in order to receive a new one. Please contact the https://bs.uib.no/ before coming so that we can arrange to have a new one ready.
PS. Remember to bring your old adapter so that we can deliver it on to our supplier.

Regards
The IT department
