doesn't open, hard restart, recharge and recognized on computer
I have a paperwhite. Everything was normal until yesterday. I had recharged it on saturday. I used it on saturday and sunday (there should be still pretty much battery). But i couldn't open it on sunday evening. Couldn't restart/hard reset it. I plugged it on my computer. It didn't show up on my computer. Even if battery is dead, i thought i could see it on my computer as a USB stick. I charged it for 10 hours but still battery lamp is orange not green. What is the problem ?
