I work on a HP laptop plugged in most of the time, and after few months the battery went off-duty.
Of course, I could remove the battery each time the laptop is plugged and place it each time I must move where no sockets are around. But I think that:
- it would be really BORING!
- The computer would not avail of the useful backup power supply a battery can provide in case of black out.
I think that in 2012, among all the automated tasks a computer can perform, having no built-in charge management software on a laptop is really deplorable for HW houses.
It should simply switch off the battery charging when a safe power level is reached (i.e. 95%) and start recharging it not every five minutes, but only under a certain safe threshold (i.e. 40% - 50%).
In its energy-saving profiles, Windows 7 only allows to set up screen brightness, screen fadeout, screen deactivation and the suspension, not managing any charging issue.
Googling the question I discovered Dell has a "battery life extender" software. Is there some platform-independent similar software for this task?
