How to shutdown computer automatically at a specific time



For last few days I was searching for a technique to shutdown my laptop automatically at a specific time. My broadband package allow me to download unlimited data only at night i.e from 2300 hrs to 0600 hrs. So, I want some sort of technique to shutdown my desktop before 0600 hrs otherwise I will be charged for downloading data by my ISP. And finally I got a trick. You might also be facing such type of problem. But don't worry friends a trick is here to solve your problem.

Trick 1:
  • Start > Run
  • Type 'shutdown -s -t 1800' without quotes
  • Click OK
  • A dialog will appear showing the countdown timer
Note: 1800 is the amount of time remaining before your computer shutdowns. 1800 is in seconds - 60sec * 30 min = 1800 sec. If you want to shutdown your desktop after 1 hour simply enter 3600 sec, as 60 sec * 60 min = 3600 sec.

How to cancel the shutdown timer ?
  • Start > Run
  • Type 'shutdown -a' without quotes
Trick 2:
  • Right click on desktop, Go to New > Shortcut
  • Type 'shutdown -s -t 1800' without quotes
  • Click Next
  • Type whatever you want to name the shortcut link.
  • Click Finish.
  • Now a shortcut is created in the desktop.
  • Just double click it and your shutdown timer will start.
  • You can customize the look of the shortcut. 
  • Right click on the shortcut icon, Go to Properties > Customize > Change Icon > Select any icon from the gallery > Click OK
Trick 3:

In this trick we will create a shutdown job by using the 'at' command, which is used to schedule task manually in windows.
  • Start > Run
  • Type 'at 13:26 shutdown -s' without quotes, it will shutdown your computer at 13:26 
  • If you type 'at 13:26 shutdown -s -t 60', it will shutdown your computer after 60 sec from 13:26 hrs
  • Click OK
How to view the list of jobs along with their attributes in your computer and how to abort the jobs ?
  • Start > Run
  • Type cmd
  • Type 'at' without quotes. It will display the list of jobs in your computer.along with their Status ID, Time of execution, Command to be executed etc.
Now, if you want to cancel the shutdown job that we had created.
  • Start > Run 
  • Type cmd
  • Type 'at 1 /delete' without quotes. Here '1' represents Status ID of the job. I have already mentioned in the above paragraph how to view the Status ID of the job.

DDR/DDR2/DDR3 SDRAM - The neurons of computer

For last few days I was searching for a 2GB DDR2 memory chip to upgrade my laptop memory. And during this search I come across a memory chip developed by PRO. PRO are developing neurons for computers means 'memory modules'. They provide lifetime warranty on the factory original computer DDR2 memory for Apple, Dell, HP, IBM, Sony and Toshiba. Isn't it awesome ?

Technology on which memory(DDR2/DDR3 SDRAM) depends:
  • ECC Registered - Error Correcting Code enabled RAM. It requires mother-board support. Basically used in servers.
  • Fully Buffered DIMM - It is used to increase reliability, speed and density of memory systems.
  • SO-DIMMS - Small Outline Dual In-Line Memory Module, these are used in systems which have space restrictions such as laptops.
  • DIMMS - Dual In-Line Memory Module, contains a series of dynamic random access memory integrated circuits. Designed for desktop,workstations and servers.
  • RDIMM - Registered Dual In-line Memory Module
On what does today's server, laptop, Mac or PC depends ?
All the above mentioned technologies Quality ECC Registered, Fully Buffered, SO-DIMM, DIMM & RDIMM DDR Memory Modules.
Guys don't think that by just installing any branded DDR3, DDR2, DDR Memory Modue RAM in your server, laptop, Mac or PC does not implies that your system will work at its best. Even if you install oem (original equipment manufacturer) DDR2 memory modules, they will not guarantee that your system will work at its peak. But PRO memory upgraded system will be in top during benchmark because its memory modules are equipped with all the new technologies (ECC Registered, Fully Buffered, SO-DIMM, DIMM & RDIMM DDR Memory).
As I am a Software Professional, I need lots of memory for developing programs, running IDE (Integrated Development Environment) and business application softwares simultaneously. In my analysis I found Pro memory module expansion is the best for developers and end-users. May be it 8GB, 4GB, 2GB or other RAM module expansion options trust PRO and upgrade your computer memory like a PRO!

How to find your stolen/lost laptop


Friends as modernization is on its peak. Everybody nowadays are using Laptop, PDA, iPhone etc and chances of theft is also increasing. So, how to keep your Laptop, PDA, iPhones etc secure. I had found a Open Source Software 'Adeona' which can keep track of your laptop. If your laptop is stolen or lost you can easily trace its location and also catch the thief.





Adeona is a open source system which keep track of your lost and stolen laptop. It uses the Open Source OpenDHT distributed storage service to store location updates sent by a small software client installed on an owner's laptop. Its Mac OS Ver has built-in iSight camera which captures the image of the thief if camera is available in laptop. One bad thing is that your laptop require a internet connection to upload all its information to the server. Location information include the update time, laptop internal/external ip address, access point to which it is connected ,nearest router etc .It is available for Windows, Linux and Mac.

Steps how to find the stolen/lost laptop:
  • Just download and install it in your laptop.
  • Remember the password you given during installation. It will be required during retrieval of information regarding your laptop location.
  • Keep 'adeona-retrievecredentials.ost' in a safe place because it will be required during retrieval process. You will find this file in desktop and also in under program files 'C:\Program Files\Adeona'.
  • TESTING (not stolen) : For retrieval of information from the server start the 'Run Adeona Recovery' program from your computer if you just want to test the application.
  • LAPTOP STOLEN: Install the Adeona software in any other laptop and start 'Run Adeona Recovery' program from their if your laptop is stolen.
  • Enter the password given during the installation of the software in your laptop. Locate the 'adeona-retrievecredentials.ost' file of your laptop , I have told you to keep that is a safer place in previous instruction and start the process.
  • After that a file 'adeona_retrieve_results.txt' will be created upon completion of the retrieval process in your desktop under 'adeonaretrieval-08-26-2009-1653' folder. '08-26-2009-1653' in folder name refers to the date and time of retrieval process completion. So it may change in your case.
I had tested this software its really working. Below is the information, I have got during my testing of the software. Below is the format that you will also get in adeona_retrieve_results.txt :-
  • info: ========== START STATE RETRIEVE ==========
    info: state updatetime: 08/26/2009,16:42 (IST)
    info: succesfully retrieved update replica 0
    info: ======== start location data =========
    update time: 08/26/2009,16:42 (IST)
    internal ip: 120.13.420.217 //your IP Address
    external ip: 120.13.420.217
    access point: technozonebiti //acess point to which your laptop is connected
    Nearby routers:

    12 207.000ms 192.33.92.161 (rou-open-net-switch.ethz.ch)
    info: ========= end location data ==========
Description of the above statements. In the above statements you will find update time,internal ip, external ip and nearest router details.
  • Update Time: The time when your laptop information is being send to the server.
  • Internal IP: IP address is being assigned to your laptop by the ISP (Internet Service Provider) when the laptop was connected to the internet.
  • External IP: IP address is being assigned to your laptop by the ISP (Internet Service Provider) when the laptop was connected to the internet. Basically internal and external both are same.
  • Access Point: The access point used to connect your laptop to internet.
  • Nearby Routers: The routers that are nearer to the internet network your laptop is connected to.

To trace the IP Address location:
  • Just put the Internal Ip you got from the adeona_retrieve_results.txt file into the text field below and click search, you will get the details of the ip address along with a map or search the ip address with any ip geolocation service to retrieve the location of ip address from where your stolen laptop is being connected to internet.


Enter IP Address:

By the help of this open source software you will easily trace your laptop location. If exact location cannot be found, atleast you have an idea about the locality where you will find your laptop. After that you may contact cops for catching the thief.
