			=== Not Powering Up Anymore ===

			There are reports
			([https://forum.pine64.org/showthread.php?tid=12661 #1],
			[https://www.reddit.com/r/PINE64official/comments/q8d08a/pinecil_does_not_power_on/ #2])
			that Pinecil that has been working stopped powering on. Note this is different from black screen issue mentioned above - in this case, Pinecil simply does not power on and also does not recognized as an USB device. Also, it is not an USB-PD compatibility issue as the device has been working fine up until this issue.

			It has been reported that dead USB-PD controller (FUSB302MPX) was the cause. While the root cause of the failure is still unknown, Pinecil can be 'repaired' by removing the chip, allowing it to be used as a DC-powered soldering iron. Removing FUSB302MPX (small 5x5mm QFN) requires some effort, but it is doable by careful desoldering (or hotair desoldering).
