Hey Darth,


There is something between NTC and Ground! It is the temp sensing circuit!  Try an SD card with the skit "Startup script to disable battery temp sensor"  and see if it starts!


Cheers!

thx, but unfortunately nothing happens...

another tip:
pleo that works with original battery with switch on -> see over usb, with switch off -> no usb (like as expected)
pleo that works with custom battery [with 10kohm resistance, or without is the same] with switch on -> see over usb, with switch off -> see over usb (!!!)

pleo that don't work with original battery with switch on -> no usb, with switch off -> no usb
pleo that don't work with custom battery [with 10kohm resistance, or without is the same] with switch on -> see over usb, with switch off -> see over usb (!!!)

I think there is a circuit inside the pleo between the 2 negative poles that check something. And there is something broken in my broken pleo.

thx for reply.
no, both the pleo are ugobe.
the strange thing is that the original battery (that works on other pleo) don't work on this (both ugobe).

Hi Darth,


3 beeps means the battery is low on charge and Pleo has saved his (or her) current state before shutting down, and it is safe to remove the battery. When the battery is low, Pleo will assume the standard box posture EXCEPT that his head and tail will be down and not straight.


Am I correct that you own a RB version of Pleo?


Cheers!

Ok I have more info.
First of all I connected pleo to pc, and see if the pc see it (on macos this is the command system_profiler SPUSBDataType).
With original battery (that works on the other pleo) no result.
With my modified battery (that also works on the other pleo) I see it!
This is the output:
Pleo:

          Product ID: 0x0100
          Vendor ID: 0x6962
          Version: 1.00
          Serial Number: 110401014598
          Speed: Up to 12 Mb/s
          Manufacturer: Ugobe Inc.
          Location ID: 0x14100000 / 12
          Current Available (mA): 500
          Current Required (mA): 100
          Extra Operating Current (mA): 0

So it's very strange.
However it doesn't start, but I exclude the fuse.
So I put the sd card with firmware, and with power switch on or off (it's the same) I can hear three beeps.
What this means?

Thanks

Hi Xu Peng,


Here are the power stats from a powered up pleo, not what you asked for, but an intermediate step!



<=== SENDING COMMAND ===>
stats power
                  Battery Voltage = 83, Min 83, Max 84 (tenths of a volt)
              Battery Temperature = 23, Min 23, Max 23 (degrees C)
                  Battery Current = 278, Min 278, Max 2659 (milliamperes)
             Battery sensor value = 100 (% capacity remaining)
      Battery sensor direct value = 100, Min 0, Max 100
              Battery Voltage A/D = 743, Min 643, Max 745
          Battery Temperature A/D = 345, Min 232, Max 346
              Battery Current A/D = 39, Min 39, Max 372
            Thermistor Resistance = 11390, Min 9713, Max 11448 (ohms)
      Battery Internal Resistance = 0, Min 100000, Max 0 (milliohms)
        Battery Capacity Consumed = 10 (mAh)
                       Powered up = true

Hi DarkS,


The fuse is a good place to start if there is no sign of life at all!


Cheers!


Peter

I don't know the exactly reason, but now it works.
I install popos then lifeos 2.0.1, but nothing.
Meanwhile I have modified the battery pack.
Reinstall popos and the lifeos and now seems work.
So I don't know if I have fixed with the battery restoration or with the several tries with updating system.

Now I have to come back to life the other pleo, that seems never used, but doesn't give life sign.
I'll try to see the fuse as the first try.

thx

Hi Xu Peng,

I am working on it, but it might take me a while, okay!

I have a mock up that was working (but now is giving me problems).  I would rather use the mock up so that I don't have to deskin my working Pleo.

I will let you know as soon as possible.

Cheers

Peter
