Re: Ubuntu 16.04 is reaching EOL next month; can I upgrade?

Getting support may be essential for many, but is not always the case (e.g., fixed and static installation, never touch the Internet, etc.)
Please see the chart here to decide which next version to choose:

Re: Latte Panda Alpha Not Powering Up Blue LED blinks

Okay, now it appears the POWER SWITCH, the device itself is fine. There are other potential failure points: 1. USB-C 15V 3A power adapter is not functioning properly 2. too much peripheral devices connects to the LP Alpha (draw too much current) 3, BIOS setting is corrupt Possible fixes: 1. get a qu...

Re: LattePanda Alpha issues on battery power (No charging)

Q1: Why Arduino is still powered Ans 1: I suspect the Windows is in the "Fast Startup" mode, when you shut it down. Please check this fix to see if it works: https://www.lattepanda.com/topic-f23t18595.html Q2: incorrect battery State-of-Charge reported A2: as you can see in the 3rd link of your post...

Re: Latte Panda Alpha Not Powering Up Blue LED blinks

Please perform the test I suggested above (post #6).
It is simple, just use a small flat blade screwdriver.

Re: Lattepanda Alpha 864 not powering trough USB-C but powering with 12V DC

It looks to me the USB-C PD-source mode (supplying power to a device such as your phone) works. But the USB-C PD-sink mode (taking the power feed from a power supply) failed in someway. Per your description, it seems to be the USB-C COntroller works in both modes, but the actual POWER-feed path fail...

Re: Latte Panda Alpha Not Powering Up Blue LED blinks

Okay. Then the next diagnosis step is to perform a "power switch" turn-on test (by not using the existing "PCB Power Switch"). The procedure is to use a snall flat-blade screw driver to short the "SW" socket (see picture) for 3 seconds or so. Be CAREFUL Do NOT touch anywhere else. It simulate the sa...

Re: Lattepanda Alpha 864 not powering trough USB-C but powering with 12V DC

Changing power flow direction is indeed the USB-C's tricky design (and flaws). I found playing around the USB-C use cases and gadgets. Sometimes, the faulty situation got automagically removed. At least, temporarily. For me, using 4-pin DC_in seems to be a good one. Other than that, it's phase of th...

Re: [LattePanda Alpha] LabView Interface for Arduino Leonardo

The link in between is just a regular serial port off the x86 processor to the Arduino Leonardo. ... another USB port back-to-back connects to on-board Arduino Leonardo's USB port (latter emulates a COM port, detected by Win10 as COM3) You can always use Arduino IDE to verify the port number is corr...

Re: my delta can't boot, stop at logo and shows 98

POST code 98 usually means need a USB keyboard for the boot process to complete.

A2 probably means "no boot drive"

A new, fresh CR927 battery should be replaced into the battery slot. It probably will last at least a year or so.

Re: Lattepanda Alpha 864 not powering trough USB-C but powering with 12V DC

Sorry the new USB-C power adapter did not work out for you. The mysterious USB-C controller hickup inside the LP Alpha/Delta is a big puzzle for a few people. My general advise is: if it works, take it as a blessing. Actually, I blame USB-C standards. Overly ambitious, trying to do too many things, ...
