LattePanda 3 Delta red blinking and blue led but no boot
My LP 3 Delta has been working fine till today. Now, when I try to boot after connecting to power supply with the standard adaptor, the following happens every time:
1 blue light turns on
2 green light turns on and very quickly off
3 red light starts blinking for around 10/15 times and then turns off
4 blue light remain fixed, but nothing can be visualized on my monitor (no hdmi output). Keyboard leds are on.
I tried the "hard reset" method and I tried to remove the RTC battery, both methods did not work.
Thanks in advance for your help.
