Keep taking the tablets

Tablets seem to be all the rage at the moment. I’ve been working with three different types over the last month or so and thought I’d share my observations. These are base on my personal circumstances and needs – yours may be quite different.

The 3 tablets are in order that I...

Kindle Fire quirk

Quick report of an oddity that I discovered with the Kindle Fire.  If you copy an ebook in mobi format onto the Fire you can read it with no problem.  If you select remove from device when you have finished reading the book it disappears from the list on books on the device. The file...

Computer report

A recent post on the powershell.com site asked about running a Windows command (batch) file through PowerShell against remote machines. The batch file was expected to produce a number of files of data in a folder structure based on computer name. This makes it difficult as we could in theory run...

Monitor brightness–or not

In this post

root\wmi–set monitor brightness

Oddly the methods for changing the brightness aren’t on the WmiMonitorBrightness we get a separate class with the methods. This function can be used to set the brightness

function set-monitorBrightness {
[CmdletBinding()]
param (
[ValidateRange(5,20)] ...

root\wmi – Monitor brightness

The monitor brightness can be discovered like this

function get-monitorBrightness {

$monitors = Get-WmiObject -Namespace root\wmi -Class WmiMonitorBrightness

foreach ($monitor in $monitors){
  $brightness = New-Object -TypeName PSObject -Property @{

root\wmi – WmiMonitorColorCharacteristics

The rather long winded name of this class might put you off but it does show something useful

Get-WmiObject -Namespace root\wmi -Class WmiMonitorColorCharacteristics

produces these results (dropping the system properties)

root\wmi–MSBatteryClass

Posted by: Richard Siddaway

A number of the classes in root\wmi return results from more than one class. That sounds odd but it can be explained by an example.

The namespace contains a number of classes related to the battery in laptops

gwmi -Namespace root\wmi -List *battery*

MSBatteryClassEvent ...
