Reboot reboots your Nokia 9200 series communicator
without having to remove and reinsert the battery. Err.... that's it! For why
rebooting is important, read on...
Why is Reboot needed?
No operating system is
perfect and there will always be memory leaks of some kind or other. Symbian OS
is great in many ways but rather fallible when it comes to holding its own on
the memory front. As third party software in particular is started up and
perhaps closed again, memory gets gradually allocated and messed around.
Now, to a certain degree, the operating system copes with
being messed around, with firmware versions 4.xx and above containing built-in
routines that kick in when the free execution memory drops below a certain
point, optimising memory and closing down built-in applications until there's
enough room to breathe again.
Sooner or later though, mainly on the older 9210 and
9210i, it's time to consider a reboot, clearing execution memory right down and
reloading the operating system into execution memory. After a reboot, a 9210
communicator should have around 3MB of RAM free (well over this, in fact, on a
9210i). The process of rebooting only takes about 30 seconds and no data should
No data lost? Are you sure?
Yep. In fact, the
Communicator is outstanding in terms of data integrity. Everytime you switch an
application away from the foreground or close the communicator's cover, its
data is automatically saved into flash memory inside the device or onto your
expansion card, as appropriate. So, even with Sheet or Word files open, you can
reboot the communicator and you won't lose a thing. Honest.
So why not just remove the battery then?
to save wear and tear on the battery catch and contacts, partly to save time.
With a complete battery removal cycle, the phone side of the communicator gets
turned off as well, so you have to power it on manually and then re-enter your
PIN and other security information. With Reboot, you just use it from the
Extras bar and after the operating system is up and running you'll be pleased
to note that the phone's on and ready to use as normal.
How often should 9210 owners use Reboot?
depends on what you use your 9210 communicator for. Light users who mainly use
the built-in applications can probably get away with running it once a month.
Moderate users who use the 9210 heavily and have some third party applications
will probably benefit from using Reboot once a week. And heavy users,
especially game players, will need to use Reboot or similar as often as once a
day, to free up execution memory for large games or street maps, etc.
NOTE: this release doesn't appear
stable on the 9500. Please use

grabbed and unzipped, please read my README.TXT file if
you're unsure about installing software on the communicator.
