Battery Life

By its self this code is rather simple and meaningless but useful when adding to scheduled tasks or applications that take a long time to run and have the potential of running on a laptop.

Before using the code below in Design View you’ll need these:

• 1 Progress Bar
• 2 Labels
• 1 Timer

Public Class Form1

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Timer1.Enabled = True
        Dim psBattery As PowerStatus = SystemInformation.PowerStatus
        Dim perFull As Single = psBattery.BatteryLifePercent
        If psBattery.PowerLineStatus = PowerLineStatus.Offline Then
            Me.Text = "Battery Indicator - " & perFull * 100 & "% Battery Power"
        End If
        If perFull * 100 < 10 Then
            MsgBox("Your battery is running really low you may want to plug in.")
            Application.Exit()
        End If


    End Sub

    Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
        'Objects for retrieving the information
        Dim psBattery As PowerStatus = SystemInformation.PowerStatus
        Dim perFull As Single = psBattery.BatteryLifePercent

        'Show the remaining battery power in percentages
        ProgressBar1.Value = perFull * 100

        Label1.Text = "Total battery power remaining: " & perFull * 100 & "%"
        Me.Text = "Battery Indicator - " & perFull * 100 & "% Battery Power"
        'Is the battery charging?
        If psBattery.PowerLineStatus = PowerLineStatus.Online Then
            Label2.Text = "AC status: Plugged In / Charging"
        ElseIf psBattery.PowerLineStatus = PowerLineStatus.Offline Then
            Label2.Text = "AC status: Not Plugged In / Not charging"
        End If



    End Sub
End Class
