I suffered through about a month of misery of having my Treo 600 hang on me, typically while trying to place an outbound call or just seconds after receiving an inbound call. The screen would freeze for about ten seconds and either the outbound call would never go out, or the inbound call would be disconnected. In the top left corner “Sprint” would sometimes be replaced by “print” or “rint” and the message “No Service” would also appear at the top of the screen.
Oddly enough, email and web access were not affected nearly as dramatically. Sometimes the Treo would hang for a few minutes while downloading email, which would chew through a lot of the battery’s charge, but it didn’t happen that often.
Another problem is that the battery ran down really quickly. It needed to be recharged every day. The only way the Treo could survive a weekend without charging was if I turned off the wireless radio each night.
Finally, I got around to searching the web to see if this was a common problem. Of course it was. It’s easy to forget that there are a gazillion people out there like me who have problems with things and then post on the web about it. Just like this blog post.
Other people had reported this problem on the TreoCentral (here’s one of many threads on the topic) discussion forums and on several other Treo discussion forums. The first proposed solution was to send your Treo back to Palm if it was still under warranty and the ESN on the back was between 09600716001 and 09600864216. Mine is in that range, but is long since out of the warranty period.
The next thing people discovered was that replacing the battery would fix the problem. I came within one click of ordering a new battery before I decided to take one more look at what people had posted.
I then discovered a couple of posts suggesting that the problem was with the battery connection. The real benefit of replacing the battery actually came from reseating the battery connection. While the Treo would still work with a loose connection, it caused battery discharge and wireless radio problems. I suspect this might be because of undesirable drops in voltage or current across the connection.
To make a long story only a little bit longer, I used some excellent online instructions from gethightech.com to take apart my Treo and reseat the battery connection. Those instructions are for replacing a battery, but they tell you exactly what you need to know to just fix the connection.
Problem solved. It’s now been almost two weeks since I fixed the battery connection, and I haven’t had a single reoccurrence of what had become a near daily problem.
Update 11/1/2006: The problem came back. I reset the battery connection again. Unfortunately, now my Treo reboots everytime I turn it on. I did a battery reset, which fixed the reboot problem, but caused my Treo to no longer find the Sprint network. Then I did a hard reset, and everything seems back to normal.
