Battery Removal
The four battery door screws use a T-9 driver
or a 3/32" hex key. A 2.5mm hex key can
work, but is a bit too large. When the screws
are completely removed you can use a flat
screwdriver in the slot where the hose cover
comes out to pry off the lid over the battery-
it seals very!tightly, so it will take some force
to pry the door open. Once the lid is off you
will see the battery with three wires and a
connector attached to three pins coming
directly out of the Cobalt's case. You just
need to remove this battery connector from
the pins.!
Restoring Firmware
!If the internal firmware needs to be restored after a failed update attempt, this should be done
while the battery is removed, using either the Cobalt_firmware_update_Mac application or the
Windows firmware updater.!The updater requires an extra step!if no battery is present- you must
unplug and replug the USB cable from the Cobalt after starting the update process.
Replace Battery and Restart
Cobalt
The battery connector can only be
plugged in one way. You can leave it
unplugged as long as you like- no
memory will be lost, but plugging in the
battery needs to be done with a single
quick motion so as to provide the
processor with an appropriate reset. If
for some reason the Cobalt doesn't
start up in 20-30 seconds, try removing
and replacing the battery connector
again.!
If the computer does not start up when the battery in replaced, either the battery is dead (possible
if it has been sitting a long time) or the firmware internally has become damaged- this can happen
if the firmware update process was interrupted by pulling off a cable mid-stream, for instance.!See
restoring the firmware above.

Reinstall Battery Door
Reinstalling the battery door is much easier
and will make a better seal if you carefully
remove the tiny rubber ball that makes up
the overpressure relief in the battery door-
its locations is visible inside the battery
door as a raised circular boss with a hole in
the middle. If this ball is not removed there
is a tendency for pressure to push the O-
ring off the sealing flange, possibly causing
a leak.!You can push the ball out from the
inside of the door with a paper clip or
something similar. Be careful to catch it
on the other side- it can pop out
suddenly and fly away!!
Press the door back over the O-ring and
fasten the screws. If the factory sealant is
still covering the opening for the ball it
might be very difficult to press the door
down- id so, scrape some of the sealant
away to allow for air passage. You should
get a small rush of air from the opening as
you press the battery door down. After the
door is sealed on the O-ring and the
screws are back in place press the rubber
ball back into the small opening from the
outside. Use a small dab of silicone sealant
(silicone glue or caulking) before inserting
the ball to help seal it in. The hex key or
T-9 driver is just the right size for pressing it solidly home.!!
Important note on restarting a Cobalt with a depleted battery:
If the battery is completely dead, use the AC charger to reset the computer, not USB. USB will
charge the battery, but won't generate a reset pulse.!If you only have access to USB, you can use
that to charge the battery, but will need to remove and reinstall the battery to restart the program
as soon as there is sufficient charge in the battery to run the Cobalt (which should take just a few
minutes). The USB can then be used to recharge the computer normally. !
