Charing laptops at school.

What are the negatives of Rimu students charing there laptops at school.
1. It cost almost $ 6450 a year for every student to rimu house to use a charger.
2 We could be spending $ 6450 on resources for us instead of power.
3 We would have around 30 chargers in the class by the end of the day.

What are two of the suggestions for solving problems.
1 Have 2 tickets and you can choose when we want to use during the year when we want to use them.
2 You should use your brains and charge them at night and if you don't work in a book or sit at the teachers desk.
