How to save power ( lower the energy bill) when using a desktop/laptop computer

Using Microsoft OS in default setting is not very energy efficient.

It will be consuming & wasting too much power in default settings. So your electricity bill will go up.

Also in laptop it will cause to generate more heat, which the inbuilt fan will not be able to dissipate properly.

You can do these settings to lower the amount of energy spent on CPU.

 

  • Goto Control Panel
  • Open “Power Options
  • Select “Power saver
  • Click “Change plan settings” for the active power plan

You must also do other settings in “Power options Advanced settings” so that it works as you want it to.

I always keep my computer ON. When I am away computer keep downloading.

Here is the settings that i do.  You may do the setting similar to mine or you may do what you like.

  • Set “Sleep after” to “Never” as shown below

  • Additionally you should use GPU inbuilt in processor as it saves power compared to using external graphics card, for your day to day tasks.
  • For gaming, video editing and graphics processing you can use external graphics card.

How to use strong password and keep it safe

I strongly suggest that you use password managers like LastPass to store all your login credentials.

Then you only need to remember one master password for the password manager account.

Also use good internet security like Kaspersky, Bitdefender, ESET, Trend Micro.

You need to use a strong master password.

But memorizing a strong password is not easy. Most people can remember pronounceable words and number.

No problem. You can use easy to remember words and number . I will tell you how to make it stronger so that other cannot guess it or crack it.

 

suppose you can remember words like “dragon warrior” and a number like “49637”.

Now I will tell you how to create a very strong password just by using these two by formatting and repeating it.

First, combine it

  • dragonwarrior49637

Format it like this

  • |dragon||warrior||49637|

Further, expand it by repeating the characters like this

  • |dDdrRraAagGgoOonNn||wWwaAarRrrRriIioOorRr||444999666333777|

You can further format it like this

  • ####$$$$|dDdrRraAagGgoOonNn||wWwaAarRrrRriIioOorRr||444999666333777|$$$$####

You can use the above text as password which a very strong password.

Similarly, you can create your own formatting technique that you like and can remember it.

Here are more examples of strongly formatted passwords using “dragonwarrior49637”

  • +++++[[[[[dDrRaAgGoOnN]]]]][[[[[wWaArRrRiIoOrR]]]]][[[[[499666333377777]]]]]+++++
  • $[dragon]$[DRAGON]$[warrior]$[WARRIOR]$[49637]$[49637]$
  • (—–d—–r—–a—–g—–o—–n—–)(—–w—–a—–r—–r—–i—–o—–r—–)(—–4—–9—–6—–3—–7—–)
  • |||||<d><r><a><g><o><n>#####<w><a><r><r><i><o><r>#####<4><9<>6<>3<>7>|||||
  • =====DDDDragoNNNN^^^^WWWWarrioRRRR^^^^44449637777=====

Similary you can create many strong passwords that are easy to remember.

Don’t use too complex formatting otherwise you will forget it.

 

How to keep your important files/documents safe from being modified/deleted or stolen

In today’s world, your important digital documents and files  need to be protected from hackers and malware.

Hackers could steal your important files which could cause a lot of trouble for you

malware’s could encrypt your important files if you don’t keep it safe. They could also delete your important files.

This method will work for you if access your important files less frequently.

Your first line of defence is a good security software. Use good internet security softwares like Kaspersky, Bitdefender, ESET, Trend micro.

If somehow malware gets installed in the computer then your second line of defence is to keep important files separate & disconnected from the computer.

 

Use Pendrive to keep your important files

  • So my first suggestion is to keep your important files in an external Pendrive.
  • If possible keep two copies of important files in the pendrive.
  • Pendrives are available cheaply and are very reliable compared to hard disk
  • Don’t keep that Pendrive connected to your computer all the time.
  • Connect it to the computer when you need to access the important files. When you are done then again disconnect the Pendrive from the computer and keep it in a safe place where it is not accessible to others very easily.
  • If possible encrypt the content of Pendrive using encryption tools like BitLocker or VeraCrypt

 

Encrypting USB pendrive using Bitlocker

  • I am using windows 10 Bitlocker as an example. I suggest you upgrade to Windows 10.
  • Insert the USB pendrive into the computer
  • Open “Control Panel”
  • Click “Bitlocker Drive encryption”

ENCRYPT PARTITIONS WITH BITLOCKER_30-07-2016_20-39-58

  • Scroll down to the list where your pendrive is shown
  • Click “Turn on BitLocker:

ENCRYPT PARTITIONS WITH BITLOCKER_30-07-2016_20-40-13

 

  • Tick “Use a password to unlock drive”
  • Enter the password
  • Click “Next”

 

ENCRYPT PARTITIONS WITH BITLOCKER_30-07-2016_20-40-36

  • Select a method to save the recovery key

  • I am saving the recovery key in a file

  • Click “Next”

  • Click “start Encrypting”

ENCRYPT PARTITIONS WITH BITLOCKER_30-07-2016_20-41-45

  • Click “Close” when encryption is complete

ENCRYPT PARTITIONS WITH BITLOCKER_30-07-2016_20-42-00

  • You have successfully encrypted the USB pendrive.
  • You can save your important files in the pendrive
  • You need to enter the password to access the content of pendrive

ENCRYPT PARTITIONS WITH BITLOCKER_30-07-2016_20-42-19

 

Keep the important files on a separate partition in the hard disk

  • If you don’t want to use Pendrive for some reason then you must keep the important files on a separate partition on the hard disk. This is less secure than the previous method.
  • Create a separate partition with size that can hold all your important files. You can resize the existing partition to make space for new separate partition using free partition managers like

AOMEI Partition Assistant Standard Edition :  http://www.disk-partition.com/free-partition-manager.html

MiniTool Partition Wizard Free Edition :  https://www.partitionwizard.com/free-partition-manager.html

  • If possible encrypt the content of the partition using encryption tools like BitLocker or VeraCrypt

 

  • Using AOMEI Partition manager I will resize an existing partition and then create a new partition to store important files.

HOW TO KEEP YOUR IMPORTANT FILES SAFE_30-07-2016_18-46-07

  • I will resize the H: partition to create free 2GB unallocated space which will be used to create a new partition.
  • Right click on the partition that you want to resize. In this case, I right click on H: partition.
  • Select “Resize partition:

Get maximum Read Write speed from internal hard disk data drive/volume/partition

To get maximum read-write speed from Internal hard Disk partition you need to Format it with “NTFS” File system and set “Allocation unit size” to 16-64 Kilobytes.

By default allocation unit size is 4KB.

Increasing the Allocation unit size makes it much easier to manage storage space but it also causes wastage of storage space.

So if you worry about wastage of storage space then use Allocation unit size as 16 KB.I recommend using 16 KB as Allocation unit size.

Otherwise you could use highest 64 KB.

Note : Formatting the Internal hard Disk partition will Erase all the data in it.

The internal hard disk in your computer may have multiple partitions. This technique should only be used in  drive/volume/partition which will be used to store users data. Don’t use this tweak in Boot partitions in which Windows OS has been installed.

  • As you can see below that internal hard disk has multiple partitions named ( C: E: G: H: I: )
  • Out of them C: and E: partition has Windows OS installed. The user should not use this tweak in these partitions.
  • G: H: and I: partition is used to store users data. So we can use this tweak on it.

  • Move all the files in the I: partition to another location on the computer.
  • Select a data partition and right click on it.
  • Select “Format
