If you are using cpudyn to control your CPU frequency dynamically, you might be interested to know that it also

can spin down your hard drive. I have seen some drives that simply ignore their idle timeout setting if it's too

low for their taste. Also, idle timeout settings are done in five-second increments, which means that you can't

set it to something like eight seconds. cpudyn comes in handy, because it doesn't rely on your hard drive to

detect idle periods, and it can spin it down whenever you want.

Use a known working AC mains lead and AC adaptor of the same type (if you have one).
Connect the AC adaptor to a mains wall socket that you know is working (e.g. if you normally charge from an RM NoteBus, remove the adaptor from the RM NoteBus and use a wall socket instead).
Switch the system on and check that the power icon at the bottom right of the system has a 'mains plug' symbol and that it says On AC Power or Charging when the pointer hovers over it.

Remember: Your battery is slowly degrading all the time, even if it is not used. Keeping your battery as cool as possible will slow down this degradation considerably.


Lithium-Ion batteries are rated for 300-500 full discharge cycles, after which time they will deteriorate rapidly. In practice, this means that if a school uses the notebooks twice a day, every day, the batteries will only last one year or so. However, if you employ a method of frequent top-ups between use (ie do not allow the battery to become almost fully discharged) then you should get 2 or 3 years of use from them. During this period however, the length of time that a full charge will last will decline by as much as half.

If a Lithium-ion battery is always kept cool, it should last for several years. If it is kept at a warm temperature for most of its life, it will not last much longer than one year. This is why most manufacturers will only warranty their batteries for periods of between three months and one year (maximum capacity).


Notebook BatteryInfo is a more meaningful display of mobile computer battery charging capacity. By default, Windows has only a small battery icon in the Taskbar as a capacity display which isn't much good.
