hello all. been awhile.
The charger on my phone is broken, so i decided to use this phone as a tethering device for my carcomputer.
its a palm treo pro, and i would rather power it from the battery bay anyway since that would shut the phone off when i disconnect the power.
i cant get the phone to turn on by just supplying 3.7v to the battery terminals. there are 4 ternminas, and the two outside ones are definitely the main voltage, but the two terminals inside do something that tells the phone its OK to use the battery.
anyone know how these work? to get 3.7v i just used 4 diodes off a 5v usb cord and 3.6ohms of resistance.
thanks!
