1) The first 3 pink boxes simply mean the computer is not set to sleep after it has been idle for a while and the wireless card is set to max performance even when the computer is on battery.
This is a matter of individual preference, you can change them in the power plan advanced options and in the wireless card options. Mine is set to exactly the same.
2) The 4th pink box says avaerage CPU utilization is high. The culprits are given in the yellow boxes- windows media player, aero, chrome, skype and some windows processes.
3) The battery appears to be in a weak condition since its only holding about 40 % of designed charge. This really depends on the age of the computer, I have a 2006 machine which holds about 32 % charge. If you use this machine a lot on the go, it would make sense to replace it, otherwise if it stays at home, just keep it on power. You might get a slightly better statistic by recalibrating the battery (charge fully, then drain till laptop shuts down automatically, then charge battery back up again, then check) but i doubt the effect will be momentous.
