Brilliant ‘scope detective work‘ by Neil Ramsay over at Blood, Sweat and Solder, revitalizing an otherwise dead Kindle DX Graphite.
I have an old Kindle DX Graphite lying around. The Lithium Polymer battery on it was well below charge and the safety on it was refusing to allow a recharge via the Kindle’s USB port.
I opened up the Kindle, set my bench-top power supply up to 3.7 V and connected it to the battery headers, that I had soldered some jumper wire to. The Kindle refused to boot!
I decided to jump start the battery with my PSU, but I also wanted to break Amazon’s restrictions and get the Kindle to boot without the battery.
I did some Googling but found very little. So here is what I learned along the way:
