				Sage near unusable when charging
			 
			
			
			When I first got it a couple of weeks ago and was setting it up I encountered the worst input lag using the on-screen keyboard and other bits of the UI.  It went away, so I put it down to maybe old firmware. 
		
	
		
		
		
		
		
		
		
		
		
		
	
	Last night I had to charge for the first time since then (while reading) and found once again that the interface became really laggy and unresponsive. As soon as I unplugged the USB cable it was fine. Has anyone encountered this?  |

			No, and I've read a number of times while charging. Mostly I charge from a wall socket, not a computer, though.

			I have to agree with Sirtel.  I've often used my Sage while charging and I haven't noticed any lag.

			I've used mine while charging and it's been fine.

			That doesn't ring a bell, no. 
		
	
		
		
		
		
		
		
		
		
		
		
	
	One random idea, though: if it's currently inside the PowerCover, get rid of it (that thing's an unrecoverable buggy mess anyway), as I *have* seen the cover doing... all kinds of nasty things to the system.  |

			Agreed. My charger (from a Lenovo Yoga Tablet) is about x5 faster than the USB2, USB3 or USB-C ports on my computer. So I only charge via PC/Laptop if I've been using Calibre and continuing to work at PC.

			This has not turned out to be consistent at all.  It seems fairly random, but I’m also getting more failed page turns (swipe, not keen on the buttons) than on the Aura.  Might just still be getting used to it.

			I've not experienced this with my Sage or any ereader that I recall.  I am certainly no expert, but I assume you have tried different books in the event of corrupted files, changed out adapters and cables.  My next step would be to perform a full factory reset (not a restart), add only one book, and test again.

			Try rotating the charger that's plugged to electrical plug.  
		
	
		
		
		
		
		
		
		
		
		
		
	
	Try to charge from a USB c power bank Try using a grounded USB c charger. Like the one from laptops, plugged to a properly grounded electrical plug. If those fixed it, then it's electricity leak/grounding issues.  |

			USB-C power bank or charger is irrelevant. Any USB-A works, though some 1.5A ones charge at full speed. 
		
	
		
		
		
		
		
		
		
		
		
		
	
	I've never seen an earthed/grounded USB charger. Also most laptops are not earthed/grounded. I live in a Country that uses earthed 3 pin wall sockets always, except for isolated shaver sockets.  |
