Get back the original backup time from your laptop batteries
Laptop batteries tend to develop a memory effect after a while. Use this tip to eliminate the side effect of constantly recharging laptop batteries when it is not required.
Battery memory occurs when it gets conditioned over time to run for less time than it is designed for or capable of . Say for example, you run your computer on its battery for an hour and then you plug it back in to let it recharge. The battery will be come conditioned to run only an hour before it runs out of juice.
To correct Battery Memory problems, you must completely drain the battery and recharge it. To completely drain the power of your battery, you need to go to your Windows Control Panel and select ‘Power options’, here you must first disable any ‘Power Management’ settings.
Next, you must go into your BIOS and make sure that if there is a power management setting, you turn it off as well. In most cases, once you are inside the BIOS, you will highlight ‘Power Management’ and select no action for ‘Critical battery’ setting. Once these steps have been completed, use the Escape key to return to the top level menu, and select ‘Save Settings’ and exit.
Once you have completed turning off the power management in both the BIOS and the Operating System., you must unplug the computer from the AC connection, turn it on and let it run until it completely runs out of power. Then you should change the battery for 12 hours. At the end of the charging cycle, run the computer again until the battery is dead, and then charge the battery for 12 more hours. You should repeat this process of recharging the battery for half a day at least four times, before your computer returns to its original factory power management settings.
As far as the battery usage goes, it is recommended that you should use the battery once every two weeks, and keep the battery in the system so that the AC adapter can keep the battery charged at all times even when not being actively used. This reduces possibility of memory effect.
It is also highly recommended for more than two weeks, you should completely discharge the battery (drain its power) and store it at room temperature.

[...] Get back the original backup time from your laptop batteries Determining options concerned: Type ‘about config’ in the address bar of the browser and find the entries you want to block for other system users in the list. You cannot do without the configuration of the Internet proxy set by you in the example. The line ‘network, proxy, type’ sees to it that Firefox uses the proxy. Therefore, you have to ensure that this line cannot be changed. Creating a configuration file: Starts a text editor for this. Type two slashes in the first line and then go to the next line. Place the ‘lock Perl’ character string before the presetting to be blocked. For example: Lockpref(‘Network.proxy.type’,1); You can add the entries for more setting that gave to be blocked in a new line. That way, you can also ensure that Firefox always displays the preset homepage. Save this file in the TXT format; for instance, write as ‘firefox-sperre.txt’. Encoding file: Convert the block file you have just created so that other users cannot open it. The easiest way to do so is using an online encoder such as the tool on ‘http://alain.knaff.linux.lu/howto/MozillCustomization/cgi/byteshf.cgi’. Click on ‘Upload.txt to get mozilla.cfg(byteshift 13)’ on ‘Browse’. Then, browse to the TXT file you created and select ‘Open’ Click on ‘Convert mozilla.txt to mozilla.cfg’ to start the conversion and save the resulting file ‘mozilla.cfg’ in the program folder of the browser: ‘C:programMozilla Firefox’. Activating the block file: You still have to integrate the converted file to the configuration of the browser. To do that. Open the ‘greprefs’ sub folder on the Fifefox program folder. Then, open the ‘all.js’ Javascript file. Insert the following line at the end of the file: ‘pref(‘general.config.filename’, ‘mozilla.cfg’);’. Save the change and restart Firefox. Now, the blocked values under ‘about:config’ has the ‘blocked’ status. Accessing them even through menu dialog boxes is not possible any more. You can stop even experienced users from cracking the block by taking away the writing rights of ‘all.js’ from them. You can remove the reference to the CJG file within ‘all.js’ to lift the block at a later stage when it is no longer needed.
