    Hi,

    I have a issue with my LattePanda. It was working fine yesterday, then when I connected power the next day it did not boot up and there is no Red LED at all.

    Board: 4GB RAM/64GB purchased from DFROBOT.
    Regulator: 5V 3A
    It has as a heatsink & fan for cooling.
    Booted first in August 2017
    Had the board for 6 weeks but have only used it a few times.
    It worked at first, but now will not boot up and there is no Red LED at all. The Blue LED is lit, and Fan spins so the board receives power. Also, there is no display on the monitor via HDMI or 7" display.

    I have attempted:-

    - A hard reset.
    - Used different power connectors (USB Cables, 3A 5V Adaptor & powered via the CN2 headers).
    - Removed all USB devices and Micro SD card and IPS display before powering up.

    Nothing worked. I think the board is dead.

    Please advise.

    Thank You.

    Hi,

    I have tested again today and still have the same issue. No Red LED at all.

    I believe the board is beyond repair at my end.

    Kind Regards,

    Darren.

    Hi,

    I was using it as a standard Pc, it was working fine, then the next day it would not boot up. There had been no changes to it.

    Thanks,

    I just had this same problem happen to my LP. I've been using my LP for years now without issue. Yesterday it was running a windows update and after the first restart it would not turn on. Blue LED comes on with power applied but no red LED. Tried just pressing the power button again, pressing reset, hard reset, still nothing. I have been using my LP to code in SSMS and a little excel stuff, nothing major. I don't want to mess with flashing the BIOS due to lack of equipment and experience. Any suggestions?

    @Tmx001, if red LED doesn't come on when power is applied, it seems like power circuit issue. You can contact our tech support for repair service.
