Welcome to Lenovo Community!
As per the query we understood that you are facing issue with Battery problem in your Z510 laptop.
Try to update the energy management to the latest version and check for the issue,
Click here for the energy management windows 7.
Click here for the energy management windows 8.1.
Also try to perform the gauge reset: go to power manager, select battery option in advance mode, under the battery select battery maintenance and select perform reset under battery gauge.
Also try to uninstall the Microsoft ACPI application and check and also reinstall the application.
Hope this helps. Do post back if issue persists!

Thanks for the reply,
The issue could be with the power manager software as you have mentioned that after the update and gauge reset the battery is charging to 100% and discharges very slow this means the battery is in good condition.

The advice to delete the Microsoft ACPI compliant Control Method Battery in device manager, although has been known to work sometimes, is unlikely to produce any results here. The Energy manager installs 2 virtual system drivers - Lenovo ACPI-Compliant Virtual Power Controller and Lenovo Primary iM Controller. I think it is the interaction of these with Microsoft's power management that can eventually kill an OK battery. It seems that after a time it becomes impossible for windows to determine the correct battery gauging and then will over charge or discharge completely, which is not good for batteries. Then the only solution seems to be to replace a battery that was otherwise good before software damaged it.
I have kept mine on conservation mode as much as possible and will not use the Energy Manage guage reset.
