I understand you have battery issues with your laptop.
Don't worry I'll try to help you out.
Did you make any software or hardware changes on your PC?
Battery cycle life is the total number of discharge-charge cycles (Figure 1) a battery yields before it can no longer hold a useful amount of charge. Estimating the cycle life of a rechargeable Li-Ion battery is difficult because cycle life is affected by the average operating temperature of the battery and its energy discharge rate.
Basically, higher temperatures and higher energy discharge rates decrease battery cycle life. The operating temperature of the battery depends on the air temperature as well as the heat generated by the notebook itself and by its immediate environment, such as a docking station. The energy discharge (drainage) rate depends on the type of applications running on the notebook and by its power management settings.
For example, running computer-intensive applications such as CAD, gaming, and DVD movies drains the battery faster and decreases its cycle life more than running word processing applications.
A cycle for a rechargeable lithium-ion battery is the cumulative amount of discharge approximately equal to its full charge capacity. For example, 10 occurrences of a 10% depth of discharge or 2 occurrences of a 50% depth of discharge represent one cycle.
