Logitech MX Revolution Mouse and the flashing red LED
Yesterday, as I was shutting down my PC, I noticed that my MX Revolution mouse was low on charge. I placed it on the desktop charger and checked that the green charging bars were showing in sequence. But bizarrely the charging bars stopped after a couple of minutes and the LED started flashing red. I wiped the contacts on the mouse and on the charger just to see if this was causing the issue, but sadly the flashing red LED continued.
The next port of call was to take a look at the Logitech site and see if there was any explanation for the issue and whether or not a fix was available. After a bit of digging around I found a reference in the FAQ to the flashing red LED with the advice "If the light is still not on or it is blinking red on the charging cradle, please Email Us" I don't know about you but my MX Revolution is well outside of the warranty period so with this advice I just saw $ dollar signs flashing before my eyes.
So, I took the next step of a search on Google for "MX Revolution flashing red led" Quite honestly I should have done this in the first place, since judging by the number of search results that came back, this is obviously a fairly common problem! But what staggered me, was the fix that pretty much everyone suggested - give your MX a hard slap on the underside or bang it down on the table and then try charging again. Don't believe me? Well look here: Easy fix for Logitech MX Revolution not charging.
It took about 4 slaps to the underside of the mouse before "hey presto" it started to charge again without the flashing red led. Unbelievable, but true.
Do your slapping/banging with a bit of care - but there are plenty of users out there who swear that this fixes the red flashing led problem. Good luck!
