HP Ipaq hx2755 does not charge
Eric Anderson
several chargers.
I have had this Ipaq for several years without incident. In the last
few days I have noticed that it has not charged very well. Now it
does not charge at all.
I have tried the USB charger, a charger I use each night and the
charger in my car. I have also tried 2 batteries. Still no charging
is done.
The Ipaq brightens the display when the charger is plugged in, so the
charger is sensed. I don't see any place where the Ipaq says it is on
AC, however. Where does it say that? I thought it said that in the
charge remaining screen, but it does not say that. Any ideas before I
send it in for repairs? On my Ipaq 3800 I did a hard reset years ago
and that fixed it, but I have not hard reset this Ipaq since I have
had it. Any possibility that would help this, or does it look like a
hardware problem?

Sounds like it is as simple as the battery has just about died. Just pick
yourself up another battery, open the back of the unit and swap the old one
out. You should be fine.

Don't take this the wrong way, because I do appreciate feedback on
these things, but....
I said I tried both batteries I had. Sometimes I wonder if anyone
ever reads an email past the first subject and verb. I have been
trying to figure out how to word an email so everything gets read, but
I digress.....
Both batteries are good. After trying several chargers (car, house on
wall wort, USB on computer at home) and charging stand powered by wall
wort at work, soft rebooting several times, etc. I changed my USB
fast charge to slow charge and now it charged my original battery to
100%. I don't know yet whether the change to USB slow charge is the
reason
Can anyone tell me what USB slow vs. fast is all about. What if you
have USB charge off entirely? What happens if you have a wall wort
plugged into the charging stand when the Pocket PC is on USB charge as
I have now?

Oops!! Forgot to say that the Ipaq normally says "charging" when you
look at the battery state bar while it is on AC power and charging.
My main battery just said "Battery power remaining" as it would off
the charger, although the charging light on the top left of the Ipaq
was flashing normally and the backlight brightened as it does when it
senses it is on external power.
Ideas??

I feel your pain. I've found it impossible to get a sensible answer to
a question that cannot be completely expressed in the subject line.
Even that won't guarantee a signal to noise ratio greater than 0.

USB has insufficient power to charge a PDA. Different USB ports
implement this in different ways. Some current limit, but keep putting
out current. Some shutdown until you remove the load. Others require
you to go into a usb device menu to reset the power. I've got one
laptop that won't reset the usb port power until you reboot.
Different PDA's handle this in different ways. Some just don't care.
Others have two power inputs. The one hooked to usb will only charge in
slow mode or will only charge when the PDA is off. Sounds like yours
has a switch. Can't tell if it's HW or SW, but doesn't matter.
There's a whole series of threads on aximsite.com that discusses the
aftermarket charging cables you get off ebay and how they abuse
usb power.

Did you try a hard reboot before trying to charge?

Well, for some reason, the Ipaq 2755 is now charging. I took it to
work where on the charge stand it still did not charge. My next
office neighbor has a 2755 also (he heard me expound about it). We
looked on his and he had it set for USB slow charge. I set mine to
that and then it started to charge. Now I don't think that is the
total answer. I think there is something else going on here, but as
long as it works, to heck with it. Keep in mind that I have a wall
wort on my office charge stand, so I don't think this makes much
sense.
Just for grins, I would be interested to hear any ideas of what is
going on.
