Bug 511915

SUMMARY

When trying to change the default 'Stop charging at' limit, the first character of data entered is validated immediately and changed if out of range.  For example, with a default of 80, selecting this text, deleting  entirely and typing '7' will immediately be corrected to 50%, rather than allowing the user to continue typing (e.g. 75).  Similar results will arise if attempting to delete '0' from the default of '80'.

The up/down arrows work as expected, but data directly entered by the user should only be validated (and adjusted if needed) in the same manner as the 'Start charging once below' option.

STEPS TO REPRODUCE
1.  Open Power Management -> Advanced Power Settings
2.  For Charge Limit - Stop Charging at, either: 
select and delete all text, then type a single number; or 
delete the last character of the current value.

OBSERVED RESULT
Value entered is corrected to a default (50%)

EXPECTED RESULT
Allow data entry then apply data validation when user changes text field or clicks Apply, and correct if needed.
