Hi,

Hope this helps someone.

I received my device just before Christmas. I was able to start the device and update Windows 10. After a week I had the same problem where I the device was dead when powered up using the out of the box power supply.

I tried hard reseting (reset button with power button 20s with power in and without, waited a minute with power in). I even took out the battery. Nothing seems to work at all.

So, I left the device plugged in overnight and this morning the red light was on and the blue light was blinking.

The device somehow self healed. I suspect some dodgy capacitors perhaps?

Now I'm running with a NVME drive plugged in. I just hope I don't have this problem again.

Regards

Ajay @ Enjector

Dear Ajay,

Thanks for your sharing. We are also analyzing this issue. One potential reason can be the design of LattePanda Alpha is kind of static electricity sensitive because of it's technical architecture. We are also working on this issue to see if there's any solution, for example installing a case for LattePanda Alpha to reduce the static interference.

However to deal with this issue for now as we know:
1. Turn off device. Remove all power source!
2. Remove RTC battery
3. Keep it there for several mins or short connect the positive and negative pins of RTC battery holder to completely discharge the power onboard
4. Reconnect RTC battery and power source..

Feel free to let us know your further idea or problem. And we will keep testing to dig out all potential reasons..

Thanks for your support.
Enjoy Tinkering with LattePanda ! :lol:
