I have learned about problems (data loss, speaker problems, resetting, etc.) with Palm Treo 600 and 650 Smartphones which include a cell phone and PDA computing device together in a small package - does anyone have any theory that such problems with the device are caused by bad or impacted capacitor(s)? Any information would be useful.

Re: Are there BadCaps in Cell Phone/PDA Devices?
Interesting topic.
I haven't found anything about bad capacitors in these devices, but I have found two bad electrolytic capacitors in the audio section of a Sega Game Gear. Replacing them fixed the problem which was causing the sound to be very weak, even at full volume.My first choice in quality Japanese electrolytics is Nippon Chemi-Con, which has been in business since 1931... the quality of electronics is dependent on the quality of the electrolytics.

I have two TCL A30 phones.
Old Phone: This phone worked fine for years, then stopped charging If you plugged a charger into it, the phone would make the charging sound, the phone would tell you it is charging, but the battery icon would not have the charging symbol in it and the battery would not charge.I tried new battery, same behavior.
New Phone: Works fine, bought as a donor board to try and repair Old Phone
My interest here is to repair Old Phone, using components parts off New Phone if needed. I am not interested in replacing Old Phone with New Phone.... -

I have gotten so tired of battery cells leaking and it happen to this device and it is not very old I had bought these battery packs from The Electronic Goldmine for $1.00 a pack when they had a sale and I am putting 3 packs to good use so I do have to deal with leaking battery cells I am over it
I bought the label maker at Sam Club a while back for $29.99 it come with 4 cartridges and they had them on sale again for $29.99 again so I bought another one because I was not sure if I was going to able to get it to work on the battery cells that I had planned on using for this particular... -
I got a chromebook with battery problem. It was charging when plugged in. But the indicator just showed that the battery was below 10% no matter how long it was plugged in. I took the battery pack out. There are two cells in series. Each cell had a voltage of about 3.7V. I charged one of them with a lithium cell charger. I can see current going into the cell at about 500mA. After several hours, the voltage was just about 3.8V. I charged it again manually by connecting 4.2V to it from a power supply and set the maximum current to 500mA. I can see about 100mA going into the cell. But the voltage...
