I Canna' Get No Power, Captain!
You can take all the precautions in the world, but your
batteries are still going to drain. Would you like to watch? The battery meter is normally
buried in the EXTRAS folder, but utilities such as Backdrop+ move it to the
desktop; PowerOff adds a
digital % readout button to the backdrop app; Battery Metrics adds a status tab to the
lower left of the screen.
But for the ultimate in battery babysitting, Newt's Battery is the power user's
way to watch those milliamps trickle away. And if you need to be even more analytical,
BATLOG, written by Dick Campbell, will
provide an MP2xxx current load timestrip for some real number crunching.
For everything you may have wanted to know about batteries
and charging, be sure to check out the Newton Battery FAQ.
NiCad Battery Pack
- Nickel Cadmium for the 110/120/130 series.
NiMH Battery Pack
- Nickel Metal Hydride for the MP2xxx series. 1 hour recharge.
- Conventional NiMH AA Cells
- Jeff Byrkit
reports that Radio Shack sells standard form-factor 1200 mA/h NiMH rechargeable batteries
($10 per pair) and a 4-cell NiMH/NiCad charger ($17). Jeff warns that the charging runs
hot, and he is unsure whether the 8-hour cycle of the charger could cause damage to the
5.5 hour recharge time of the cells.
9W Power Adapter
- Run on AC power and charge your NiCad or NiMH battery pack
at the same time! Conversion plugs available for European outlets. The AC adapter for
older MessagePads (Layne Harris has a
limited quantity of these available) is different
from the MP2 versions, but still compatible. Enfour
has announced their own $20 power adapter, but product info is not yet available.
Solar Charging Station
- A solar panel assembly complete with its own carrying case
will keep any Newton battery pack charged.
- Dock your 110/120/130 in the cradle and charge your battery
while in use. Can also charge an external battery pack simultaneously.
- A docking station to operate and recharge your 110/120/130,
plus an external serial port for connecting to desktops. An optional modem on the serial
port can be shared by both Newton and desktop.
