Samsung Galaxy Tab 2 Charging Loop

I'm finally blogging about this, because I've had to do this several times for my kids' Tab 2's when they fully discharge the battery.
The battery and the device will be 'out of sync' and will not report correct voltage, then the internal charger will 'loop' showing a charging cycle start, then crash and restart the charge again with the same result of crash and restart.
Remove the charging cable from the device, then hold down the power button for a full minute.  Time yourself.  It must be at least 60 seconds.  This will reset the charger.  When you plug it in again, it will show nothing at all.  Wait at bit, then push the power button again, briefly.  It should then start the proper charging cycle.  Allow for a full charge before removing from power.
Hope this helps!

Surviving Starlink Beta

 I was approved for the Starlink beta at the beginning of March 2021, and have been using it not quite daily since.  It was very simple to set up, just as advertised.  I am not yet using it as my main service, as I ordered a mount to put it up on my antenna pole.  The speed is quite good, although there is a little noticeable drag as it switches between satellites.  One thing I found amusing was as I was testing the speed, I was testing on dslreports, and it allows you to set the type of service.  However, when I set it to satellite, the server said my response time was too fast for me to be on satellite, and I had to set a different service type.  I hope the speed lives up to the promises, and I am happy that this service has come out for my location, as I doubt fibre will ever happen here.

Leaving LastPass for Bitwarden

 Now that LastPass is beginning to charge for logging in on more than one device many are leaving the service.  I must admit I have been a stalwart LastPass user for several years, and was dreading the change to a different service.  However, I have moved over to Bitwarden, and even though they don't include as many things as the old LastPass did, they are still quite good, and I plan on staying there.  Since they are more open-source some things aren't quite as well integrated as LastPass was, and I still have not been able to get their Chrome extension to work.  Nevertheless, I am happy with the offering, and, ironically, I may start paying for some of their premium services! Have you switched away from LastPass, or are you wondering what I'm talking about?  Let me know in the comments!

ATSC 3.0 or NextgenTV

Image
In case you've missed it, changes are coming to our beloved broadcast TV!  After several years of great HD content, with the best signals available, it was apparent that the local stations were getting left behind in the push to UHD, or 4K.  To remedy this situation, several markets in the US have already started to rollout the new channels, and over the next couple of years, this service will be in most major markets.   In order to receive these new signals, you will either require a UHD TV with an ATSC 3.0 tuner built in, or purchase an external tuner.  If you don't have a UHD TV yet, and your HD TV is working fine, you may want to wait until all of the manufacturers have added them.  So far, only a couple have added them to their higher end sets.  I will be following up with more on this over the next few weeks.  So stay tuned!
