1. Power Management Solutions ALL Day Power for Mobile Computer Labs

2. Inefficient Charging Systems Poorly Designed Supplemental Power Options Limited Battery Power Other Limitations of Internal Batteries Issues Preventing Effective Use of Mobile Labs

3. Inefficient Charging Systems Limits the number of laptops able to be simultaneously charged Requires multiple or higher than average electrical power circuits

4. Poorly Designed Supplemental Power Options Modular secondary battery option causes loss of optical drive Add on battery chargers for secondary batteries are cumbersome and require even more cords and power AC adapters requires disassembly and reassembly of cart power and then wires are strewn throughout classroom

5. Limited Battery Power Maximum of 3-4 hours of run time in a 6+ hour school day –Laptop batteries die during later class periods –Laptop lab not available to every class period throughout the day –Laptop lab not a good fit for online testing

6. Other Limitations of Internal Laptop Batteries Lithium Ion Batteries are limited to 300 – 500 charging cycles –Batteries only last 1 ½ - 3 years before needing replacement Runtime is severely reduced as battery ages –Means even less availability throughout school day
