Why Laptop Performance lower on batteries

Why is my game running slower than expected when on batteries ?

The answer is, when your laptop is running on batteries, it tries to save power by reducing the clock speed. Thus the full speed of the CPU is not used and a lower clock speed is set. This is what that causes the game's poor performance.

How can i get the maxinmum performance on batteries ?

Performance can be gained by sacrificing power. So all you have to do is goto the
Control Panel » Power Options » Change the Power Scheme from Portable/Laptop to Home/Desktop. (Windows)

By doing this the laptop does not uses power saving schemes and your game will run at a better performance.

Got a Better answer?

Fedora Core 6
In FC6, changing the default driver from vesa to nv (nvidia) driver can cause the mouse pointer to disappear. Mouse pointer may be hidden or cannot be seen. So add the following lines to /etc/X11/xorg.conf to make it as follows :


Section "Device"
Identifier "Videocard0"
Driver "nv"
Option "HWcursor" "false"
Option "AddARGBGLXVisuals" "True"
EndSection

Auto mounting File Systems in Linux

Some Linux Distros (like Fedora Core 6 FC6) do not automatically mount the local file systems such as FAT/FAT32 systems that belong to the windows drive. To mount and unmount file systems you must be logged on as a root user or must have root privileges

Mounting Manually

First change to root


@localhost ~]$ su
Password: Password
root@localhost ]# mount -t Filesystem Device Directory

Mounting the file system manually is done by the mount command.

Filesystem is vfat for FAT/FAT32 File System.
Other filesystems that could be given can be found on
/etc/filesystems


The Device can be got from System > Administration > Logical Volume Management which shows local hard drives and its name as
/dev/sdaX
or
/dev/hdaX
etc.

The Directory specifies which folder must the file system be mounted into. For example if you want to mount to mnt/hddC/ the device /dev/sda8 (FAT32) , the full command is

@localhost ~]$ su
Password:
root@localhost ]# mkdir /mnt/hddC
root@localhost ]# mount -t vfat /dev/sda8 /mnt/hddC


NTFS
Install ntfs-3g module by yum install ntfs-3g

root@localhost ]# mount -t ntfs-3g /dev/sda5 /mnt/hddD -o force

Unmounting the File System


@localhost ~]$ su
Password:
root@localhost ]# umount /dev/sda8


Automatcially Mounting File Systems :

To automatically mount certain file systems, so that we do not want to do the same procedure each time the computer starts, we have to edit the
/etc/fstab
file. To edit the same you must have root access. Assuming you have root access to mount a local Filesystem, add the following line.


Device ID Mount Directory FileSystem Options

Eg:
/dev/sda8 /mnt/sda1 vfat rw,umask=0000,uid=500,gid=500 0 0


where the uid=500, gid=500 must be replaced by the proper user ids which can be got from System > Administration > Users and Groups in Fedora Core 6.

Automounting NTFS
Append
/dev/sda8  /mnt/hddD  ntfs-3g  default 0 0



Help me
I did this in Fedora Core 6. If any of you guys have any information on how to do the same on other linux distros , or if you have any other information, please post a comment.
