Tip & How-To about Tablets & eReaders

How to always plug the mini-USB charging cord in the correct way.

I see several people having problems with their charger cord not plugging into the device so it charges or not staying plugged in because it comes right back out etc. I have found a way to make sure I don't damage those somewhat delicate and very small, mini-USB charging ports which are usually not repairable or replaceable.

I *borrowed* my wife's red fingernail polish and then I plugged in the charging cord on all of my seven or eight different devices and wall chargers which I have all labeled so I use the right one - I use masking tape and simply write the device name on the tape with a pen.

But, back to the red nail polish - I put a splotch of red nail polish so I can see it from the front of the device when it's plugged in correctly. This way the next time I plug it in to charge it, I'm not taking a chance of trying to plug it in backwards which can surely damage the female, mini-USB port, metal catch tabs and electrical pins.

my tablet wont turn on unless connected to a power supply and when its connected the screen stays black


I'd check the tablets internal battery and also the cord and plug from the charger. Though the cord powers it enough to run the connection may be too insufficient to -keep- the battery charging. I would also turn the device completely off while troubleshooting.

Why did it charge only 13% all day plugged into an electrical outlet?


The cords go bad, check a different cord and plugin.

My nextbook 7 will not charge. When I plug in the charger it would begin to charge for a dew seconds and then the charge will drop. I thought that maybe it was the charger, so I tried the charger on another device. The charger charged the other device. What is the problem with my tablet, and is there anyway to fix it??


Is there an indicator light that comes on when the charger is plugged in. If so, does it stay on. If there is and it does then there may be a problem with the battery. If there is a light but it goes off when you wiggle the plug when it's plugged in, then there may be a broken connection inside where the charger plugs in to the socket.

no power


I had the same problem! It's not your charger, it's the tablet.


Most likely, the soddering came apart on the inside of the tablet, on the part that connects the charging port with some important wires. You can either take the cover off and fix it, but if it's like mine, it'll just come apart again.
This is what i did: plug in the tablet, and cross the cord from the right across the screen, to the left, and make sure it's tight. I use a binder clip to make sure it stays and charges.
