A flash code of 4 amber, 1 white or a constantly flashing amber light would be indications of a Temporary Battery Failure. The 4,1 code in particular would be due to 2 possible reasons. Either the battery has become too hot and has shut off the charging function to try to cool down the battery, or the computer has experienced an Over Current Protection event while charging and has shut off charging temporarily to protect the computer. Both of  these scenarios are recoverable. However, the computer does not charge until the Temporary Battery Failure condition has been removed.

This is working as designed to protect the computer. Use the following steps to recover the charging capability of the computer and stop the blinking LED code from being displayed:

1. Reseat the AC adapter. This can be done by disconnecting the AC adapter for ten to fifteen seconds and reconnecting it to the computer. If the Over Current Protection circuitry has triggered this, it resets the protection and resumes charging
2. If the battery has gone above its thermal threshold, move to a cooler ambient temperature environment and wait for the computer to cool. Once the battery temperature has decreased, the computer should resume charging.
3. If still unresolved, perform a Hard Reset:
   1. Power the system off
   2. Remove the bottom cover and disconnect the battery cable
   3. Hold down the power button for 10 seconds
   4. Reseat the battery cable
   5. Power the system on and test to see if the issue is resolved.  
4. If still unresolved, test with a known good OEM battery if available
