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...
