Kobo N418 : power question

Fred2Nice · 07-17-2024, 04:07 AM

Hi there,

I replaced the SD card with a new image ( thank you for the image

The screen still display "Power off" overlay on my last book.

I test the battery power : 0v, I removed the battery, now I can read 4v when I plug the device on my PC, but nothing append, kobo not detected.

Before to buy a new battery, can I test to send power directly to the card ?

Or something to check to see if the reader is really dead ?

I trired with second image, the screen was cleared, something is alive.
I added a wire to power it with usb instead of the battery
I have dots, but stay on stage 3 black dots, then blinking, and start again.

So I don't know if it is because I use alternative power, or if I can do something else ...

I tried with another card 32G instead of 64G.
The difference, no more 3 black dots, 2 black, last one empty, and just after a reboot.
