[Update: Re-written with a better hack on November 14th]
How about having your computer start up by itself; Download stuff at the odd times in the night that your telco feels you can enjoy unlimited plans; and then sleep/shutdown by itself; while you sleep soundly all the while :)
That's exactly what we'll learn to do.

Software you'll be using (200KB)

I just love this simple software to turn on and turn off the PC. It does it's job as advertised and is quite simple to use. The screenshot below shows the program with preferences set to start utorrent (you can have anything here) at 2:10AM and then turn off the computer at 7:50 AM.



We'll also make use of Scheduled tasks in windowsj; with the scheduled tasks you can have even more programs turning on automatically. You can find a neat write up on using Scheduled tasks here

If your service provider times your connection properly then this should be it. You're done and enjoy your sleep.
But I've found that certain operators don't have enough intelligence in their PC's and over-charge you for using your computer beyond your stipulated time. For eg: suppose your free download time ends at 8AM in the morning and you start a 200MB download at 7:50AM. By 7:59:59 you'd have downloaded 150MB and then by 8:03AM you download the remaining 50MB. But the stupid/whatever telco would charge you for the whole 200MB!!! In case you have had this problem use this work around.
The batch file below will simple issue commands to ur modem to disconnect and reconnect to the network. This way you'll have a time-stamp to disprove the telco.

Type out the lines between <---start of code----> and <---End of Code---> into notepad and save it as "bsnl.bat" or anything for that matter, the extension should be "*.bat"
<-------------------------------------Start of code--------------------------------------------------------->

Code analysis: {skip it if you are okay using a random script }
line 1: it's simply a comment line
line 2: turn on Firefox {change the location if you installed firefox elsewheree}

line 3: this'll wait for a few milliseconds. This is to let firefox to turn on. 
line 4: this line of code will turn on firefox with the link shown. It'll simply disconnect the internet connection. 
line 5: another wait so that the modem has disconnected fully
line 6: this time we'll connect back to the network and the URL does just that




Now this batch file will be scheduled to run using Windows Scheduler. Schedule the batch file to be run twice. Once at around 2:11 Am. Just after the Computer is woken up by W.O.S.B and again just before the computer is shut down. that’s around 7-49AM in this case. Enjoy the limited unlimited plan with lots of sleep and no strings attached!

This article will teach you how to make the best use of your Broadband plans which offer unlimited Downloads at insane times of the day.

UPDATE:Also Read the article on an extremely simple method to automatically turn on and off your PC without any of the following fuss.

Some of the major Broadband providers (e.g BSNL in India) offer cheap plans wherein you have a data limited internet usage during the day but you get unlimited downloads during your sleeping hours (e.g 2.00 AM to 8.00 AM in case of BSNL in India). So, if you have to download stuff off the web you have to wake up at this time of the night and then lose sleep for an hour trying to figure out the links and then wake up again in 5hrs to switch off your internet connection.

The best way to use these plans would be to automate the whole process of switching on the PC. beginning the downloads and then turning it off by itself. I will show you exactly how to do this using resources available on a Windows XP PC and few free softwares.


1. How to Automatically turn on your PC at an assigned time

We will use the task schedulder of windows to automatically wake up your PC from 'Hibernation' or 'Stand-by' (You cannot turn-on your computer automatically after it is turned off) .

i.Go to 'All programs' --> Accesories-->System tools-->Scheduled tasks

You will find the following screen:


ii.Click on 'Add Scheduled Task'


iii.Choose the Torrent program or any other program that you wish to start at a predefined time.


iv. Choose a time when your have free usage of the web and click on next

v. For the task scheduler to work properly you must create a password for your user account. ( if you haven't yet created one, click here to guide you through the process)

vi. Make sure you checked the 'open advanced properties tab'. This is critical to wake up your PC. (tip: you can also access the following screen by right clicking on a task under scheduled tasks and then clicking on properties)

Select the option 'Wake the computer to run this task'. This will automatically turn on your PC from hibernation or stand-by and then run the task. ( how to enable hibernation in Windows XP)


Click on 'apply' and 'OK', that's it ! your PC will now wake up by itself every night at 2:05A.m and will turn on utorrent. and utorrent will begin downloading stuff off the web without any intervention from you.

Kougon Tip: Since you can schedule any file to run by itself at a prescribed time. You can have our torrents begin by themselves. Save the torrent file onto your computer. And then make sure your Bit Torrent client will save data to a default location. Have the scheduler to run the torrent and lo! your torrents will begin to download by themselves without you having to put them inside a client!



2. How to turn-off your computer automatically

Even though this sounds like the harder task, it is actually quite easy to turn off your PC automatically. I prefer using a freeware called 'Shutdown After' to do the same.

The software is a 3.2MB download and is worth every byte of it.

Click here to download Shutdown After v2.2

The software is self explanatory in nature and has very few options. You can either set your computer to turn off after a prescribed amount of time has elapsed or at a particular time.

Set the time at which you want your PC to sleep, Hibernate, stand-by, Shut down or even Restart! and it will happen.



Using these two tricks you can have your PC waking up and shutting down all-by-itself without you having to intervene at all!!!





UPDATE 1: Some people have reported that their internet connection does not resume automatically when their PC's come out of standby. Here is a work-around for this problem.

In-order to address this problem what you need is a software to automatically configure your internet connection. One of the best softwares out there is Toshiba's ConfigFree. Using a small hack you can use this software on any computer.

The following lines were taken from a forum of PC WORLD.

Configfree will run every time you turn on your PC and will automatically configure the web for you.You will not be without the web whenever you recover from standby or even after a shutdown.
