How can I bypass the charging port on a textbook tablet

Hi Elizabeth.
Problems charging Android tablets usually stem from either the charger or the charging port itself. If you notice your tablet isn't charging, set it to Air plane Mode and reduce the brightness to extend the battery life while you work to solve the problem. Back up your files while you can, in case the problem can't be solved at home.
Sometimes the problem is with the charging port of the tablet itself. Examine it to see whether it's bent or misshapen. The connector on the charging cable needs to be able to fit well, so that all the pins on the charger are correctly attached to those on the port. If your port is damaged, it may need to be fixed or the entire unit may need to be replaced. You should also check the connector on the charging cable to make sure that port is correctly shaped and not damaged.
Sometimes using an incorrect power adaptor can prevent a tablet from charging. Look at both the base of the adaptor that plugs into an outlet and the cable itself. Very long extension micro USB cables, for example, charge more slowly than shorter OEM cables. Check the manual that came with your tablet to see what type of charger you need. If you're charging the tablet from a computer USB port, it may prevent the tablet from charging correctly. Use a wall adaptor and see if it fixes the problem.

Does it have a micro USB charger/charging port? This was the universal charging adapter most manufacturers other than Apple moved to around 5 years ago. In my experience, the charging port to charger connection can become loose and prevent charging....especially if you use the tablet or phone during charging. The best method I have found to troubleshoot the issue is to try a charger that successfully charges another device and plug it into the tablet or phone. If your device still does not charge, and especially if the connection is loose, it is most likely that your charging port is damaged. Another possible issue would be the battery itself but the charger or charging port is the most likely culprit for your issue.

Some tablets have a charging port and a usb port. If your tablet is so equipped it should charge while connected to another computer by usb or to a usb charger.

If your tablet is only equipped with a usb port and that is broken, it will need a repair before the battery can be charged.

Linda, if it is the charge port, mini USB, yes they can be fixed or replaced by cell phone/computer repair shop.

It sounds like there's a problem with the charger. The wire on the charger is rather delicate. So is the port on your tablet where the wire plugs in. There may be a break inside the wire. If you dropped your tablet while the wire was plugged in and it hit the floor on the charger plug, the charger plug could have damaged the charging port in the tablet or the wire itself could be damaged.
Find someone else who has the same tablet and ask to switch chargers to see if either of them still work on the other tablet. If your friend's charger starts charging your tablet without a problem, then the problem is a a broken wire in your charger. If neither charger will charge your tablet but both chargers charge your friends tablet without a problem, then the problem is with the charging port on your tablet.
