Dial-up connection using Command prompt

Connecting to internet using mobile partner or some other program is simple. But it consumes your system resources(around 200 MB of RAM). You can simply save your resources by using command prompt. This method is applicable only on Windows platform.

First, install the device driver and create the dial-up connection, or just install the mobile partner(or software that came along with your modem) and connect using it(it will automatically create the dial-up connection). now you can exit that program.

Here is the procedure to connect using command prompt:

  • Open command prompt
  • Type the following command
rasdial "CONNECTION NAME"
Ex: rasdial "TATA DOCOMO INTERNET"

To disconnect,
rasdial "CONNECTION NAME" /Disconnect

You can also automate this process by creating batch file.
Connect
Open any text editor and copy the following code

:Redial
rasdial "CONNECTION NAME"
if %errorlevel% == 0 exit
goto Redial;
Replace the CONNECTION NAME with your connection name(you can rename it) and save it as connect.bat

Disconnect
Open any text editor and type the following
rasdial "CONNECTION NAME" /Disconnect
exit

Replace the CONNECTION NAME with your connection name(you can rename it) and save it as disconnect.bat

Save them at the location of your convenience and just double click them to connect and disconnect a dial-up connection.

Keyboard keys not working


Recently I faced an issue with my laptop keyboard. Some of the keys are not working.
As it is still under warranty, I thought of replacing the keyboard.
When I contacted customer support, after listening to the problem he asked whether I tried DRAINING.
Then he explained me the procedure, and guess what - it's working perfectly again.

Here is the procedure of DRAINING:

  • First shut down the laptop/notebook
  • Remove the battery
  • Also unplug the adapter
  • Now press and hold the power button for about 25-30 seconds
  • Insert the battery again
  • Now power on the laptop by pressing power button(normal booting)

Now your keyboard will work again normally.
If the problem still persists, consider replacing the keyboard.

     Add these lines below 'ro.cm.device=YOUR_DEVICE_NAME'
    ro.lewa.version=YOUR_ROM_NAME
    ro.lewa.device=YOUR_DEVICE_NAME
    Add these lines in # ADDITIONAL_BUILD_PROPERTIES below 'ro.com.android.dataroaming='
