How to open a Toshiba AT300 to replace the USB connector

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.

Hold the power button down. Being that it is frozen may take a little longer than usual, but less than 30 seconds.

You probably broke the screen or a cable popped out. I made a video on how I replaced the screen in one.

Hi, you can buy new ones from here 2 pcs Replacement Micro USB Charging Port Connector for Vizio Tablet... and change it . take a look. enjoy

Sounds like there might be dust inside of the laptop that is blocking one of the air vents. Plus the connectors to the screen may need to be reseated so that way the screen can be moved freely without it locking up on you and cutting off.
You have two issues going on. Bring it to somebody so they can open it up and make sure the air vents are cleaned out. Also they need to make sure the CPU fan is running properly. Then with the screen the connectors need to be reseated. Its also quite possible the screen connector might need to be replaced.
If the laptop is under warranty see if Toshiba will reapir it.

it's a digitizer (hardware part of LCD screen) problem, U can try to buy that part and replace it or just squeeze a little bit LCD screen on the edges around (don't squeeze the screen itself but just black plastic frame around the screen) - it helped my Toshiba for a while :)

pls get ur cdrom service & try again but prior to that pls check ur data cable which is connected to ur pc

I found the same problem on one that I bought from a guy for $100. He had been picking it up by the screen and every connector in the screen and the pivot came loose. I was able to tighten every thing back up and now I have a real nice laptop.

Hi

The Satellite R10-S802TD doesn't have built in bluetooth device, however it's bluetooth compatible. any external bluetooth adapter will work. Toshiba recommends
PA3370U-1BTM Toshiba Bluetooth SD Card V1.2 or
PA3405U-1BTM Toshiba Bluetooth USB adapter as indicated you product's spec sheet.
Please post if you need further assistance.

Good Luck
