Ipaq H3835 PDA - won't hold charge??

If you purchase a new battery, they usually come with directions and special tools to change the battery. I had the same issue with 2 of mine when I got them at a used electronics store. IF it is the battery that is not working, then replacing it is easy, and you can get a replacement at your local Battery-Plus store.

In my case, one was fixed by a new battery, the other was not, and I actually had to press pretty hard in the cradle to get the second one to work. It never worked out of the cradle, so I gave that one to a neighbor kid to tear apart and see if he could get it working. (I got them for $15, so no big loss.)

You will need to change the battery (If you can figure out how).
In the manual there are no instruction and there is little indication just by looking at the PDA to figure out how to replace the battery.

I think the circuitry of charging the IPAQ PDA has some flaws. It will blow up and mess up the battery if there is surge of current flow, and the the battery is already fully charged. For example if you leave the Battery on a charger and let it stay and if due to storm or whatever else power goes out and then comes back on again IPAQ Battery is likely to get damaged. The sudden surges of electricity are of course cause problems ion all sort of products, but IPAQ charging circuit is very little (no tolerance) to cope.

They should have added a resistance to cope with this, even if that meant longer charging time.

So if you do get a new battery, be careful in charging it. As soon *** it is fully charged take it out its charging stand.

Seems there is a bad connection with the mainboard and the battery or the battery is dead.

Might need to replace the battery or atleast check the connections inside.

I had 3950 myself few years ago.
