Windows 7 Power Efficiency Diagnostics Report

0

Finally… a OS power efficiency report for Windows! This can help laptop users determine if a driver is bad or not installed, or if the battery is charging completely.

1. To run click on the start button and type “CMD” in the search bar.

2. Type in the command “powercfg -energy” and press enter.

This process will give you a general report shown is the command prompt and also build a nice html report. In my case it put the html file on the C: drive at C:\energy-report.html.

3. Navigate to the report using Windows Explorer and open the html file with your browser (Internet Explorer, Chrome, Firefox, etc.)

4. The report will show you programs that are consuming CPU time AKA power.

For laptop users testing the battery charge:
Near the bottom of the report is information about CPU utilization, processes, and this little gem (screen shot above) This report can help troubleshoot battery usage and charge capacity. This gives admin’s a great way to decide when a battery should be replaced. If the last full charge is consistently dropping from the design capacity it may be time to replace the battery.

With this report Admins can tweak power profiles to realize the maximum benefits of new power efficient computer systems.

Some more info about energy costs:
A kilowatt-hour means using 1000 watts of electricity for 1 hour. Ten 100-watt light bulbs lit for one hour would equal 1 kilowatt hour, or one 100 watt bulb lit for ten hours would equal 1 kilowatt-hour, costing 10 cents. So if one 100 watt bulb costs 10 cents to run for 10 hours and there are 8760 hours in a year, and you push a few buttons on a calculator (876 x .10), you’ll find that the actual cost is $87.60!

My power is now 11 cents per kilowatt-hour, so the cost is now 876 x .11, = $96.36 per year.

If you plan on leaving that 100 watt bulb on a lot, it is worthwile to buy the compact fluorescent version, that uses about 20 watts for the same brightness. (20 watts for 1 year at 11 cents per kilowatt-hour = $19.27 , or about 20 cents on the dollar)

An electric clothes dryer or water heater can use four to six thousand watts. Fortunately, they only operate for short periods of time. (4000 watts for 1 hour at 10 cents would be 40 cents.)

Cost = rate x energy, which contains these units:
$ = $/kWh x kWh

The average computer tower consumes 400 watts. If you have your computer on for 4 hours a day then you used .4 kilowatt-hours which is about $0.44… That can really add up. About $160.60 per computer per year if you use it for 4 hours a day.

Some large television sets can use several hundred watts of power. So if you’re a couch potato, add it up

How to get Active Directory Users and Computers with Exchange Management Tools working in Windows 7

1

h3>1. Install the w7 AdminPak (RSAT)

Remote Server Administration Tools for Windows 7 Release Candidate (RC)

http://www.microsoft.com/downloads/details.aspx?displaylang=en&FamilyID=7d2f6ad7-656b-4313-a005-4e344e43997d#filelist

2.Install IIS and Remote Server Admin Tools (Active Directory Users and Computers)

Use the “Turn Windows features on or off” feature to add IIS Stuff and the RSAT Stuff

4. Copy some files to your windows system32 foolder.

I used the files from my XP installation with these bat files, you will have to get them yourself
(REMEMBER: you need to run the cmd promt as administrator, use the one in accessories, right click it)

Text file of files that need to be copied

Bat file to copy from old install (assuming D:\windows\system32)

If you dont have these files available, you might find them here

5. Register the files

(same deal with cmd promt as administrator)

eg:

regsvr32 /s adprop.dll
regsvr32 /s ws03res.dll

Batch file here

5. Vista ESM

Download from here

http://www.microsoft.com/downloads/details.aspx?familyid=3403d74e-8942-421b-8738-b3664559e46f&displaylang=en

Run it to extract the MSI, then run the MSI from command prompt (with admin rights!) with the /q switch to get rid of the ‘not for vista’ error

eg: c:\users\you\downloads\esmvista\esmvista.msi /q

Wait at least 10 minutes while it does its thing.

It is is a silent install, you wont see anything, but I have had cases of it breaking because people started AD too soon.

6. Run Active Directory

Run Active Directory users and computers from your start menu.
