It could simply be a failing battery not holding its charge once the power has been disconnected
Create a battery report to check the status of the battery.
When you have the report, compare the Design Capacity value versus the Full Charge Capacity value shown in the report. For a good battery these two values should nearly be the same.
You can work out as a percentage how good the battery still is by using the formula Full Charge Capacity value x 100 ÷ Design Capacity Value.
If it is a very low percentage you may want to consider replacing the battery.
