Many laptops (I know Lenovo at least does this) allow you to charge the battery up to 80% (probably around 3.9-4 volts) and keep it there. This is ideal if you want to use your laptop with AC power, as lithium cobalt batteries lose the least capacity when stored at around 75-80% charge.
A Data and Safety Monitoring Board (DSMB) is an independent group of experts that advises the sponsor and the study investigators.

Stands for Digital Subscriber Line.. It is a medium for transferring data over regular phone lines and can be used to connect to the Internet. However, like a cable modem, a DSL circuit is much faster than a regular phone connection, even though the wires it uses are copper like a typical phone line. An asymmetric DSL (ADSL) connection allows download speeds of up to about 1.5 megabits (not megabytes) per second, and upload speeds of 128 kilobits per second.
