Hi,

my LP Alpha (backer#316) received almost 1 year ago, but used very few, yesterday it stopped working without any particular reason.
It was running with at low cpu level, when it stopped I was not present, when I realized that the board was switched off I have tried to turn it on, but no lights were present anymore.
Pushing the power button nothing changed, I have tried to check if the power supply was off, but connecting other devices to it, it charged correctly.

On the board there are no signs of shot circuit at all and no burning smell is detected.
Let me know what should i do to try to revive or to send it back to you to be repaired.
Kind regards

Fabio

re: check if the power supply was off, but connecting other devices to it, it charged correctly.

Not a valid test. LP Alpha negotiate with the USB-C power supply in PD mode and requires 15V 3A negotiation step's success.
(Can try a working power supply in the forum list instead.)

If no BLUE nor Red LED light at all, try remove the Lithium battery trick. Also change to 4-pin DC powering method. That method is much more stable.
Few threads here had discussions on those topics.
