5 Great Computer Pranks
What to Do If Your Computer Does Not Start
1. No Access to the Keyboard During the Boot Process?
Help, I can't access my keyboard at boot!
If this is the case, I would recommend:
1-1. If using a USB keyboard, plug the keyboard into the primary USB ports on the back of the computer (on the motherboard). Restart the computer and try again.
1-2. Try another known working USB keyboard plugged into the primary USB ports on the back of the computer (on motherboard). Restart the computer and try again.
1-3. Try another known working PS/2 keyboard, restart the computer and try again.
1-4. If using a PS/2 Keyboard, try replacing your keyboard with a USB keyboard, restart the computer and try again.
1-5.
If these steps fail, remove your keyboard connection and shut the
computer off with the power button. While computer is off, plug the
keyboard back into the computer and start the computer.
Still doesn't work? Please go to "I need to flash my bios" section and proceed with flashing your bios.
2. Does Your Computer Freeze at Bios?
Why is my computer frozen?!
2-1. Remove all devices from your computer including removable hard drives, additional USB devices, and printers and faxes. Restart the computer and try again. If no result, go to step 2-2.
2-2. If you can see your bios screen, please tap the key to go into your bios settings. While inside of bios, make sure that your hard drive, memory and video card ( is applicable) are detected. If it is not, try re-seating or replacing the unit that is not being detected. If no result, go to step 2-3.
2-3. While looking in bios and all of your hardware is getting detected okay, please reset the bios back to its default settings and choose "save and quit." The computer will restart and you should be looking at the operating system loading page at this point. If no result, go to step 2-4.
2-4. Open the computer, remove all but 1 memory module (usually closest to the CPU) and disconnect all hard drives. Also disconnect and PCI or AGP add on cards and start your computer.

Before we begin, you need to remember that the tips mentioned here are useful when the battery is running low. Applying the following tips will keep it working till you recharge it again or find a convenient spot to charge it up.
Using the inbuilt option for power saving
The initial step to save power is by customizing the settings of your phone in the Power Saving options. This mode will help you to maximize the speed of your CPU, adjust the background colors of your apps and programs and turn down the screen illumination a notch lower.
Choosing a dark home screen picture
Setting the profile of your home screen makes a lot of difference. If you choose to make a setting that requires a lot of bright colors then chances are that your device will consume more battery power. It is advisable to set your phone profile using darker colors. Enable a profile with darker background colors.
Another thing that you can do is to tone down the brightness. Here is how:
Settings->Display->Brightness, now tone down the screen brightness. However, remember to tone down the brightness to a level where you can still read and see the content on screen.
Making settings for screen out timings
The
Samsung Galaxy S III comes with an inbuilt feature of motion detection
that is capable of detecting if you are using the screen or not. If you
are not looking at the screen then the screen dims out. If you have yet
not turned on this feature then you need to turn it on. Additionally,
you can also make settings in Screen Timeout and make changes in the
time that will take the screen to dim when not in use.Turn off programs
Often the maximum battery power is consumed in extras like Bluetooth and Wi-Fi connectivity that are left on. It is advisable that you turn it off when not in use. The reason behind battery consumption is that they keep scanning for connectivity options while you are on a go. While your device is searching for establishing connection, it is the battery power that is being consumed.
Screen display adjustments
If your screen is adorned with interactive wallpapers and you have a fancy ringtone then the battery consumption shoots up. To be able to have that extra battery power it is better to turn off and change the interactive wallpaper. As for the ringtone, keep it simple like beeps instead of keeping it on vibration or sport a musical tone.
After applying the tips given above you can additionally do more to save battery power.
Other options
• If you are keen on saving your battery power, then you can choose to download battery saving third party apps. You can choose to download apps like Advanced Task Killer. This will help you check the battery consumption and also help you kill apps and programs that are consuming maximum battery power.
• Another third party app called JuiceDefender is a free to download app that will help in increasing battery power of your Samsung Galaxy S III. You can even opt for an advanced Pro version that can be purchased at $5.
• Samsung Galaxy S III is a Smartphone that comes with an option to remove the battery. You can replace it with a larger official battery, for example, you can opt for S III 3000 mAh battery that is provided by Samsung.
