If you have a CCI laptop... take it to them today and they will either fix it on the spot or set you up with a loaner. If it's a loaner, be sure to have them install the software needed for COMP110/COMP101.
If it's not a CCI laptop... you'll want to have it repaired or replaced as quickly as possible. The late points policy covers this kind of situation. If it will be a prolonged period you may need to depend on a friend or roommate who is not in the class to borrow their laptop and install the required software.
If you have any case-specific concerns, Message your Team and we will be happy to talk with you through the issue and empathize (however we will likely not grant extensions to problem sets due to the late forgiveness policy (see Syllabus)).
