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%
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
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

264 hours 7 minutes remaining in 100% (full) charged battery
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
    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
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

windows button right to left in Linux Mint 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!
