IPAQ trouble - won't turn on

[bill palmer]

I have an HP IPAQ 310 that I run X-C Soar on, that won't turn on. :-(

I left it in my bag for a few months and didn't use it, and wouldn't be surprised if the battery ran down.
Before that period, it worked fine and was not in a condition to suffer physical damage.
When I plug it in, the amber charge light illuminates, but even overnight charging never shows the battery fully charged.
The unit won't turn on at all, whether plugged in or not.

Searched HP forums and didn't find this exact issue with this model

Does anybody know if this is how it will behave when the battery finally gives up the ghost? I'd hate to spring $25 or more bucks on a battery for a dead unit.

Bill I use the 310 with LK8000 and did the same thing - battery was bad went to battery plus and picked a new battery been running good for a year.

you may have to do a hard reset.

This often happens when a battery discharges and goes flat for an extended period. A new battery will likely fix it.

If changing the battery doesn't fix it, I accidentally discovered that running over an IPAQ with the car takes care of similar issues.

The IPAQ 310 manual says you should take the battery out if you're not
going to use it for some time.

The problem with leaving the battery in it is that, when you turn a 310
off, some of its electronics are still running: the on/off touch switch
for draws power because it is a sensor rather than a mechanical push on/
push off switch and the clock/calendar is still active as well. These
will drain the battery if it is left in the 310 and, as the battery is
lithium-ion, running it right down will kill it.

However, replacing the battery in a 310 is really simple and replacement
batteries are available from eBay.

I had two on offer for free on glidersource for ages. along with two ipaqs and misc accessories. no takers after a year. couldn't give 'em away. ipaqs (3135 and 5555) are freecyceled and gone. still have the ipaq 310 batteries if you want them. also the suction cup mount and charger too.

Bill,

Your name is familiar as I think I sold you the 310. The unit will have these exact symptoms also if you try to charge using any cord other than the original cord that came with an HP 310 (special HP wiring)or if you don't use the USB OTG pigtail that I provided with the unit. The details are hazy but the 310 looks for one of the USB pins to be grounded to another, if I remember correctly pins 4 and 5, or the unit will not start the charging process.

When I bought the unit the owner had just replaced the battery so it is relatively new. He hadn't found this information about the charge process so the battery wouldn't charge. I could plug in the unit for long hours get the light as you describe above and the unit would never turn on or charge. After hours of internet research I was able to find the USB OTG solution and after charging with that pigtail the unit would turn on within a few minutes and then fully charge after several hours. I used the unit for multiple hours for several use/recharge cycles to make sure the battery was ok. Then also did the tests with the extra external battery for extended inflight use. You still need to use the USB OTG pigtail for that backup battery as well or again the 310 wont start the charging process.

If you're using the USB OTG pigtail then I'm not sure what else the problem could be.

[Greg Delp]

I will also add that I did find out that even if you put the 310 in it's protective carrying case, the power button is very easy to activate with just slight pressure from other items in a bag or just sliding the unit in and out of the case. Like Martin said above, I would remove the battery once it's charged just to make sure it's not drained by an accidental activation and it will be ready for your flights.

Another problem can be the lid over the battery. There is a tiny switch
near the battery, which will be pressed by the properly closed lid and
otherwise prevents HP310 operation.

Bill, I suggest you toss your IPAQ into the hazardous electronics bin at your local dump. After suffering through over 10 years of squinting at that damned thing I recommend getting an Avier, Oudie or ClearNav, whatever you can afford. You'll be glad the battery on the IPAQ died, let it rest in peace.

I'm with Herb on this one. Since you are an XCSoar user, you have many Android options as well. I've been happy with XCSoar on a Dell Streak 5, which has a very good screen, but is no longer in production.

I didn't see this response; here's what I learned when my 5555 did the same thing. I downloaded the manual. Sure enough, it turned out when fully depleted, it was required to charge in steps. Charge as you did, Unplug, Push reset button, Charge again. Then done.

Sorry if this is not the same issue for your model.

I have a 314 thatmust be 4/5 tears old, I just keep it in a drawer as a
spare, and always forget to keep it charged, so the battery does go quite
flat. After a few minutes using the mains charger, it starts up and works
fine. Just done it again 5 mins ago, after it has not been touched for
several weeks.. As has been said you MUST use the original charger and
cable. If not, the light will come on, but it is not charging. It can be a
good idea to pack the small press switch next to the battery, with a very
small bit of tape, they have been known to not make contact when the lid is
put on.
Having said that, the reason it is in the drawer is a V2, which has a much,
much, better sunlight readable screen.

That's it for me Frank! Thanks - I was trying to breath life into this old Ipaq since we use with our hotel lock system (Vingcard) - I put new battery in and it would only boot up for a few seconds then die. Tried all kinds of things to breath life- finally came across your point that the iPAQ likes to have its battery cover Covered - put the cover back on and its working like a champ now (with new battery) - swew! Thanks - I'm the hero at my work now - thanks for posting!
