When a device like that fails completely, and the charger is charging there's only so many things that can go wrong.

• The device has completely failed (worst case, but, not if nothing happened to it, no plugged in while lightning, no dropping, etc.)
• The battery won't charge. If it's not easily replaced, see a battery store, they'll usually install one for the cost of the battery, if they can open it.
• The regulator for charging the battery has failed. This means not only will it not charge the battery; but, it can't tell when the battery is charged, and it will kill the battery, this must be replaced by a repair shop, unless you know an electrician, and have the key to open the tablet.

What is your question?

Is the brightness problem only when the battery is low?

There are many reasons y0our laptop is running slow. 1. Make sure the ventilation holes of the laptop are not blocked with dirt, or blocked by placing laptop on your lap, or a non-hard surface. When the CPU gets hot, it will throttle down to run slower. You can install a temperature monitoring program to determine if the CPU is running too hot. 2. If the temperature is within normal range, then check to see the amount of free space on your HDD. Keep at least 10% or more free. 3. If that is ok, then you may not have enough ram to run all the programs. Windows 7, or 8 should have at least 4GB or more RAM. 4. If that is ok too, then you may have a lot of unnecessary programs running. Run a virus scanner program to get rid of viruses, etc. 5. Uninstall unused programs. Sort by date to see which programs were installed most recently, By doing this if you can remember when you started having problems, you can uninstall programs installed around that time that may be causing your problems. As you can see a lot of things can cause slowness. Good luck!
