BT Problem Battery/Power Problem

I recently purchaced a second hand e740 - i say second hand everything in the box was still sealed including the unit itself, when i purchaced it i was informed that it would probably need a new battery because it had been sat for 2 years un-used. i purchaced a new battery, plugged it in and charged it to 100%, then removed it from the power cable and all was good - an hour or 2 later after having it in the cradle i removed it and the second that it was disconnected from the mains power the unit shuts down - loosing all the data as if the battery was not there. i then tried to charge the original battery but that is getting stuck at a constant 1%. i was wondering if anyone knew what this problem might be and might have a way to solve it - i have checked everything i can think off - and no the hard reset switch is in the correct possition. this problem is also present when the mains cable is plugged directly into the unit it is litterally the second it is disconnected from the power it turns off and will not come back on

Re: BT Problem Battery/Power Problem

In my opinion it is always very risky to buy some second hand unit because you can not be sure if every hardware component works properly. The best solution for you is to contact service partner and let them check the PDA. It is also possible that power supply electronic has some malfunction

Toshiba E740 Power Problem


Hi, I noticed that the firmware that you have is not the latest, the last provided was 1.0623.049 which was released a few years ago. I would install this, in addition to the other patches from the Toshiba web site. Hopefully this will overwrite any software quirks for you. regards, Keith

Memory loss


the problem is based on a failure of the backup accu. This can only be fixed by a Toshiba Repair Service. They have to change a Board inside the PDA.

Memory loss/reset


have a suspicion that this whole issue revolves around the fact that the E740 uses a ML1220 coin-type lithium manganese dioxide rechargeable battery which is a 3V battery using specially treated manganese dioxide for the positive material, a lithium-aluminum compound for the negative material, and a specially formulated organic electrolyte. This is found under the left lower cover set on it's edge and like a home PC is I believe the CMOS battery which is rated at 1,000 cycles of discharging to 10% of nominal capacity (Depth of discharge = 10%). The total discharge capacity is quite high at 100 times nominal capacity. Supplies a nominal capacity of about 95% even when stored at 20 deg. C for roughly five years according to accelerated test conducted by Maxell). And since organic electrolyte is used, the battery has superior leakage resistance (shipped fully charged). I have the same issue with my unit and decided to open it up and find out about this battery. I am almost certain that this battery is no longer holding a charge and therefore always crashing an resetting. I have had the same experience with my old Handspring unit as well as an old PC. I would appreciate hearing from Toshiba or anyone else where one can acquire a replacement ML1220 as it is only supplied to manufacturers and not consumers.

The PDA turn off and it will turn back on immediately later ......


I get much the same, but it comes and goes. For a week or two it will behave itself, then goes pop for a month or three! Do you find if you have external power (cradle or USB) that it will switch off? I also find that if I switch it off from battery power, it will switch itself back on, but then the power switch is ineffective for 6 or 7 seconds. Then you can switch it off, only to repeat the whole excercise again (and again, and again, and again...)

In order to be able to turn on the unit, the Battery Switch must be in a battery "Supply" position. Please check if the Battery Switch is in a Stop position or Supply position.

When using the Pocket PC for the first time, slide this switch to the left with the stylus pen. If you have further questions, please refer to the Instruction Manual page 2-4 (21 of 182).
