      Micro$oft does have VBS code, which can serve as a starting point. After all, translating from VBS to Perl should be easy &foolish_grin;

    For win you could do something like this:

    #!/usr/bin/perl -l

use Win32::OLE('in');

my $objWMIService = Win32::OLE->GetObject("winmgmts:\\\\.\\root\\cimv2
+") or die "WMI connection failed.\n";
$colItems = $objWMIService->ExecQuery("Select * from Win32_Battery","W
+QL",0x30);

print "$_->{DeviceID} ($_->{Description}): $_->{EstimatedChargeRemaini
+ng}%" for in $colItems;

    Of course, I get percentages greater than 100% when I'm plugged in so it isn't completely ideal. =/

      well it's most certainly a start. if nothing else i can be like, "hey dad, check this out" :-)

      might even be able to play around with it and see what the problem is with the percentages...

      meh.

        For Windows scripting checkout Scriptomatic 2.0 from the microsoft scripting guys... 
        use strict;
use Win32::OLE('in');

use constant wbemFlagReturnImmediately => 0x10;
use constant wbemFlagForwardOnly => 0x20;

my $computer = "localhost";

my $objWMIService = Win32::OLE->GetObject("winmgmts:\\\\$computer\\roo
+t\\CIMV2") or die "WMI connection failed.\n";
my $colItems = $objWMIService->ExecQuery("SELECT * FROM Win32_Battery"
+, "WQL",
               wbemFlagReturnImmediately | wbemFlagForwardOnly);

foreach my $objItem (in $colItems) {
