Hello

Due to extensive use of the workstation with continuos AC power supply I chosen profile that suppose to prevent battery charging to 100% to protect it when on AC source for longer time, however it does get charged fully to 100%. The profile is genuine DELL profile within Dell Battery Information tool, called 'Primarily AC Use'. I generally use battery quite a lot, however I expect to use the laptop on AC for long periods in next few weeks/months and would prefer to not ruin it because of that reason as they are not cheap. Could anyone help, how to set it up to make sure it remains uncharged fully while on AC source?

Regards

Pat
