Well, one of the more plausible explanations for my Dyson?s odd behaviour
(namely dying within seconds of coming off charge but being ?restored? to
normal running duration by recharging for just 5 seconds back on the
charger) was that poor connection between the battery and the handset might
be the problem.

Well I removed the battery, cleaned the contacts and crossed my fingers but
it?s made no difference. I?m really puzzled by this behaviour. I did
wonder if it was just ?pretending? to have recovered so having vacuumed the
hearth, I carried on with the sitting room, the hall and then the stairs.
By then I was getting bored but it seems to have plenty of capacity.

I don?t really buy the ?dead/dying cell? theory or the ?low charger
voltage? theory as I can?t see how either of these could cause this odd
behaviour.

Seems to be that the ?battery charge management? chip is getting its
knickers in a twist and cutting the battery off at too high a voltage and
is getting ?reset? when I put it back on charge.

Does this sound plausible? Anyhow, as long as I can easily restart it it?s
not a huge problem but it is curious.

When did you last clean the air filter(s) (I say filters because some
have more than one)? I don't honestly believe that will be the cause
but tech does odd things occasionally!


*sigh*

And just how would blocked filters produce the exact symptoms my vacuum
cleaner has? Would blocked filters make it recover after reconnection to
the charger for a few seconds? I think not...

Tim;/.l

Because I had one that did just that. I have NO idea why just that
when I cleaned everything it worked.

YMMV.
