four, and using battery correction function, recovery battery charging effectiveness

Dang notebook computer using a time Hou, you is often think battery of using time how increasingly short has, actually this is because Notebook battery in constantly filled, and discharge of process in the, sometimes BIOS by reconnaissance to of power, will and battery actual power does not match the, in this situation Xia, although battery also has is power, however BIOS is will judgment power with finished, turn entered closed machine state.

to resolve this problem, some manufacturers include in the portable system BIOS "battery calibration (Battery Calibration)" function, to help with your notebook battery is full, then discharge to completely dead, and then full again, so for the prolonged absence of error at which a complete discharge caused by gateway laptop batteries, a certain degree of corrective action.

１． First of all, enter BIOS Setup, switch to the "Power" tab

2. Then move the cursor to "Start Battery Calibration" option, press the "Enter" key to perform

3. Prompt message for the notebook computer with access to the external power supply, and waits for a period of time the battery power is full of

the second, open BIOS anti-virus features

if you use a computer for some time, it must start the virus, it is intrusive in memory when the power and undermine the start sector, causing no small loss. However in recent years, start virus momentum seems to be better than ever before to the large, this is mainly because most of the system after the 2000 using the NTFS file format, to start in the face of virus attacks, have a valid defense.

1. Switch to the "Security" tab

2. "Boot Sector Virus Protection" project is set to "Enabled" to

This feature is turned on, then if a boot virus attempts to undermine the start sector, BIOS for enquiries feel to this operation and display "program attempts to overwrite the start sector" message, then you only have to press the n key refused, you can.

three, and opened province electric function

for using notebook computer of people,, battery of using time has been is user is care of problem, in cannot external power of situation Xia, General notebook computer of using time about in 2-4 hours, although meet one meeting or briefing using has enough, however if you wanted to using a entire afternoon playing report, may with to half, on will appears power insufficient of warning, if at this time side if no alternate battery, can on miserable has.

it is under no external power supply situation, we can use some power saving techniques, extending notebook computer use time, let the future by setting the LCD power saving features in the BIOS, laptopsComputers without using an external power source, slightly weakened slightly of LCD screen brightness, as a result, will not affect screen output quality and prolong the time notebooks:

1. First of all, enter BIOS Setup, and then switch to the Power tab

2. Move the cursor to "LCD Power Saving" option, press the "Enter" key to set the

3. Will options set for "Enabled" is complete

4. When the screen appears "Please remove AC adapter" information, said power has been fully satisfied, then to discharge zxcsky32645 operations, first unplug the external power supply, and your laptop power, until the battery runs out.

Note: this operation will make inroads into a period of time, you can go to do some other work, until the discharge is complete and then return to action to.

５． Battery discharge after completion and automatic shutdown, not on laptop power, then connected to the transformer to charge again, wait until the charging indicator (usually orange lights) goes out, work that is done for calibration of battery.

in General Dell Inspiron 1521 Battery, there is battery life, battery storage charge of excessive use of natural low, so we cannot guarantee that this method will restore the storage capacity of the battery, but if your battery has used not long ago, often feel that power usage under 32 runs out, you may wish to try using this functional recovery of storage battery power.

Note: too-frequent battery calibration operation is not available, or regular discharge will reduce the battery life is short, recommendation 2-3 months correction once.

an article on: "bad food" teaches you how to make laptop power more next: "bad food" teach you to love your books away with notebook habit At present, most online tutorials are desktop BIOS setting that is described, however, in recent years the share of laptops and desktops on an equal footing, to do this we will be here for you most laptop BIOS settings on the analysis of the market, including system restore, save energy, such as anti-virus, are generally ignored, but a very useful feature Ibm Thinkpad X60 Battery, you should not miss! (Notebook, for example)

first of all we introduce how to enter the BIOS settings of a laptop, in General, laptops to F2 key or combination of other keys to enter the BIOS, and the desktop using the Delete key often have significantly different.

, set the boot password

as the laptop is mostly portable, so a password to prevent theft of computer data, there is a necessity. In this tutorial, we will introduce how to use the password for the laptop lock to protect system security.

we all know, most of the password in the BIOS is divided into User Password and a Supervisor Password, both passwords can limit others to enter the system hp pavilion dv5000 Battery, the only difference lies in the Supervisor Password have full right to change BIOS settings, User Password is not. In short, if you are a User in the Password to enter the BIOS, some projects will become set. Since notebook computers are mostly more opportunities for their use, it is recommended that lock directly with a Supervisor Password for the notebook computer, it can secure your computer and have all rights

enter BIOS setting Supervisor Password

1. After power is turned on, press the F2 key to enter the BIOS

2. Switch to the "Security"

5. "Spervisor Password Is:Set" password has been set to complete

6. Last will "Password on boot" options set for "Enable", set power Shi was entered password only line, to this all set on complete has

Dang we again again power zhihou, notebook computer does not directly entered Windows, but first requirements you entered password, entered correct of password Hou, computer to smooth completed power, entered errors can then retry, but over 3 times words system will full died lock, at this time on must close computer then again power has.
