Dell laptop heats up after Shutdown/Sleep
Hello Readers,
If you are reading this, it means you might be having a Dell laptop with windows 10, which heats up sometimes, more often when charger is plugged in and you shut it down or put it to sleep and it ends up discharging the whole battery(Saying from experience).
I own a windows 10 operated dell 3542 and gives the above problem.
Today I learnt how to get rid of this.
Actually this is caused by the INTEL MANAGEMENT ENGINE INTERFACE provided by dell(Intel graphics driver).What we are going to do is to uninstall it.
Step-1-Right click on "This PC" and go to "properties".
Step-2-Click on "Device manager" on the left side of the window.
Step-3-In the "System devices" section you will see "Intel(R) Management Engine Interface", Double click on it.
Step-4-Go to "Driver tab" and hit "Disable". And "OK".
Now you would be able to shutdown your dell PC without any harm.

Unable to mount partition in linux
Hello Readers
if you are new to linux-windows dual boot , then you might this.
Why does this happen?
You might have noticed that after Windows 8 and later, boot time of os is faster as compared to Windows XP/7.For this to happen Windows save some metadata on the hardisk which disable the access to it.So, What we going to do is to turn off fast boot.
Step-1- go to Power & Sleep Settings(hit start key and type power) .
Step-2-Go to Advanced Power Setting.
On left side on the window you would be able to some labels.
Step-3-Click on "Choose what the power buttons do".
Step-4-Click on "Change setting that are currently unavailable".
Step-5- Scroll down and uncheck fast start up.
And you are done.
But turning off fast start up will affect your boot time.
Thankyou.

How to hide your files behind an image.
Hello Reader,
ooo...Steganography, very heavy word, isn't it?
If you are expecting a steganograph tutorial, I'm sorry. Because this is way sillier than that.
This post is on merging two same or different type of files, and yeah!, literally two or more files of any formats.
Below i have chosen a .jpg file and a .mp3 file.
Archive the file to be hidden, to keep both the file distinct.Using WinRar,etc. Simply right click and archive.
Step-1-Choose the files you want to merge and keep it in a single folder or location for ease.
Step-2-Make sure that you know the formats of the files chosen.
Step-3- Open Command Prompt(Win-R->type cmd->hit Enter)
Step-4- Using 'cd' to open a folder,'cd..' to go to previous folder and 'dir' to list the content of the folder, locate your folder where your files are kept.
Let your first file is file1.jpg and second file is file2.rar and resultant file is result.jpg.
Step-5-Now type 'copy /b file1.jpg+file2.mp3 result.jpg.
This will create a new file in that folder of the extension .jpg.
Try simply double clicking it.This would open file1.jpg image. but try opening it with an application compatible for .rar file.
This would open archive with file2.mp3 and you can use it.
By this way you can merge two files.
Try merging a video.mp4 and image.jpg with resultant newimage.jpg,
Now open it with photo viewer, and then by WinRar.
"Oh my god my video is encrypted behind an image, safe from my brother.LOL"
This is real silly fun, right!!.
Why don't you try merging two mp3 files or two movies and see the results.
But when you merge a file with a .txt file ad open the resultant file with notepad then you would see a bunch of codes and then comes your text on the text file.
Thankyou!!
