How much power remaining in full charged Laptop Battery

My two friends send me two screenshot took on their laptop some days ago. I installed LinuxMint 13 (Maya) on their laptop. Both of them are using Toshiba Satellite c100D laptop.
One of them shows that the fully charged battery has 4 hours 32 minutes of power to full discharge.

4 hours 32 minutes of battery power remaining at 100%

Another screenshot shows that 99% charged laptop battery has 3 hours 37 minutes of power.

Laptop battery has 3 hours 35 minutes remaining at 99.4 percent

I do not know the actual reason of this kind of different message in same type laptop and same type operating system.

How long a fully charged battery run on laptop

It is a common question that "How long a battery can run a laptop". It is Toshiba Satellite C800D and OS is Linuxmint13 (Mate). "Battery Charge Monitor" applet showing a ridicules information.
It shows that:

"System is running on battery power

264 hours 7 minutes (100%) remaining"

I am astonished! Really astonished!!

Battery Charge different /variation in LinuxMint13

I have installed Linux Mint 13 (Mate) in my friends laptop (Toshiba Satellite). I put a Battery charge Monitor applet in a panel. System start with its native 'Power Management Applet'. Both tools running smoothly. But both shows some different date about battery power when laptop running in battery. I found different information from both tool. When I just pool out the power cable from the laptop body:
 1. 'Battery Charge Monitor 1.2.1' shows:

System is running on battery power. 4 hours 12 minutes (98%) remaining

    System is running on battery power. 4 hours 12 minutes (98%) remaining  in LinuxMint 13

2. Default 'Power Manager' shows:

 Laptop battery 3 hours 40 minutes remaining (97.9%)

Laptop battery 3 hours 40 minutes remaining (97.9%) on LinuxMint13

 I am really confused. I don't know which is actual reading, which shows perfect information.

Windows button layout right to left in LinuxMint Mate

Desktop settings in Linux Mint Mate

I always like changing the position of windows buttons from right side to left side. It is a Mac like style which is getting popularity day by day. You may know that Ubuntu is using this style from years. I had told you the method of changing windows buttons layout position from right to left in Xfce desktop environment and Lxde desktop environment before.


Today I am publishing the customization method in Mate desktop environment.

This is really an easy task in LinuxMint Mate.

• First of all heed to 'Desktop Settings' through 'System > Preferences'.
• Now click on the 'Windows' at left menu.
• At 'Appearance' change the 'Buttons layout' from the drop down menu. There are two style. One is 'Traditional style (Right)' and other is 'Mac style (Left)'. 
• Change will take effect instantly.

Really great! Nah!
