[OmniBook] xe4500: ac adapter sometimes not charging

[Thomas Perl]

Hello!

(Yes, this is the second hardware-related problem mail about the xe4500
today ;)

My xe4500's ac adapter (not the one with the two cords, but the part of
the ac adapter that is on the back right side of the xe4500, where you
plug in the power cord) makes a humming noise when charging, which is a
little bit annoying. More recently, it sometimes simply stops charging
as if the power cord was unplugged, but it isn't. I then have to fiddle
around with the plug until it starts charging again, but this doesn't
always work.

Sometimes, charging doesn't start until the xe4500 has drained its
batteries and it loses power - as soon as it has lost power (and battery
capacity went to zero), it starts charging again in powered-off mode -
looks like this might be software-related (running kernel 2.6.15).

Has anyone experienced similar problems with the xe4500 or a comparable
laptop? Is there any hint or solution of this (annoying) problem which I
could try?


Thanks,
Thomas
