I have a pup that chewed the charging cord. I repaired it and am getting the
correct voltage out of the cord connector. I am getting on the lower right tray "connected but not charging" Is there a circuit that controls the charging of the battery? What would you suggest?

Here are the specifications for the power chord for your notebook. 417220-001 :AC adapter (65 watt) - Input voltage 110-240VAC, 50-60Hz, 2.4A - 18.5VDC output voltage, 65-watt - Requires a separate 3-wire AC power cord with C5 connector
Either the power supply has a loose connection or is faulty. You can try removing the battery pack, press and hold power button for 3 seconds and then put battery back in and see if it corrects the problem. You can test power output from the supply to see if it is putting out the voltage it states it should on the label of supply.
You either have bad power transformer or a bad opwer receptacle on the laptop.
You can test the power supply with a multimeter. If it gets the correct voltage, your receptacle on the laptop is broken. Repair requires replacement of the motherboard, and probably will not be cost effective.
When you plug in the adapter into the laptop a LED lights up to indicate that it is connected to the mains supply and is charging. The adapter is faulty or the connector is not making proper electrical contact. Wriggle the connector plug to see if the charge light comes on, if it does then the loose connector needs repairing.
Check the adapter with a multi-meter, the voltage reading should be a slightly higher than the voltage that is printed on the label on the adapter. If the voltage is more than 10% below the nominated voltage then replace the adapter it is faulty.
Check the adapter with a multi-meter, the voltage on the plug that connects into the laptop should have a voltage slightly higher than the voltage that is printed on the lable on the adapter. If you get nothing then the adapter is faulty and needs to be replaced. That is why the battery is not charging.
It is not a special chip that dictates if a charger can charge a certain laptop, but these two factors:
1) You need to have a power adapter/charger with the correct voltage and amps. Some common Dell laptops use 19.5V (volts) and 4.62A (amps). I have seen some Dell adapters with 3.34A (amps) as well. If you use an adapter with the wrong voltage and amperage, you could cause damage to the laptop's power supply and/or motherboard...or it just won't work at all.
2) The type of connector to the laptop. Different manufacturer's use physically different connector sizes and shapes. Some are larger and circular with a pin in the middle, while some are smaller with no pin. It depends on the laptop.
You can look at the voltage of the original charger on the brick part (the middle of the cord that looks like a brick). Make sure you get one that matches exactly.
The power connector on the motherboard is not making contact.
This is not a simple procedure to correct due to the laptop needing to be completely disassembled to get access to the motherboard.
If you gently move the power cord around in a circle while pushing towards the laptop it should get power to it until it moves out of place again. Do this while watching the lights panel for any signs of light. Also remember it will take a second or so for the battery charge light to show power entering the laptop, so move the cord very slowly.
The suggested soloution will invole the laptop being sent to your local laptop repair centre for this to be corrected, or if you still have warranty, then get it done by Toshiba.
It is also a common fault to all laptops.. There is just not enough strength in the solder that holds the power connector in place to take years of connecting/disconnecting of the cable.
The Aspires should have no issue booting without the battery installed. Have you done a static reset? (i.e. hold the power switch for 20/30 seconds without power or battery in) And the voltage range on the Aspire 5100 should be +19v - +20.5v on the inner part of the connector so it might be worth checking that the power adapter is outputing correctly.
If it works without battery, then it can be checked by testing the voltage between pins 1 and 6 on the battery (the ones either end) and should be 7.5v or above if the battery is charging correctly.
Hope that gives you a starting point, if you've done all those things already then appologies and best of luck with it.
