In notebook computers, Pavilion DV8000 battery is a love-hate component, it gives the mobile use of notebook computers the ability to continue to work at every turn but a few days compared to a week or even mobile phones and MD, notebook battery time remains a tooth If the cell phone battery can only use eight hours, people would be reviled, but it results in the notebook PC which is the pride of the best, to say the development of notebook computers in the slowest parts, in addition to the keyboard should turn the battery

That there is such a joke: Intel’s investment and technology through participation in support of the new battery technology, “For us, the lithium battery in the 1990s has been good enough,” director of marketing for Intel’s mobile platforms, said Mooly Eden, “Battery Improvement of teens just like the relationship between young people and the same: everyone talking about, but no one has done. ”

Maintenance Pavilion DV9000 batteries notebook computer users has been a hot topic, but in fact there a lot of misunderstanding, in the final analysis from two aspects, one is “thinking does not keep up with the nickel-metal hydride batteries to lithium batteries of changes”, while a more comedy, from the phone, because in fact the majority of mobile phone users access to the first use of the equipment repeatedly rechargeable battery, it will take for granted some of the habits of mobile phone to the laptop was an extension of.

I did not intend to cultivate the majority of notebook users into experts, then there is no need, I just want to bring some of the most vulnerable to clarify the misunderstanding and give the correct perspective and practices.

A misunderstanding 1 : the need for notebook computers bought three times repeated charge-discharge in order to activate the battery.

Unless you buy a notebook computer is more than one year of product inventory, or need not do so because there are Pavilion DV1000 batteries in the battery when the factory has been activated, and the batteries in the package when the battery into the notebook, after a equivalent to the activation of the test, so you get the battery in hand, already have been activated, and again three charge-discharge process was an increase in unnecessary depletion of the battery.

Misunderstanding 2: the first charge must be sufficient enough for 12 hours.

This early stage those who do not have the battery control circuit of the Ni-MH battery models are applicable, but for now have a smart charging and discharging control circuit for the notebook battery is a joke, when the notebook computer battery is full, the charge current will be automatically cut off , even if you continue to charge 120 hours, there will not be any change in status, and generally speaking, even the slowest machine charge, 6 hours when fully charged, the rest of the “charge” is just a waste of their time. It is time to get new machines should be fully discharge first rechargeable.

Misunderstanding Three: the need for regular battery calibration, the total charge released once a month.

Strong memory effect for nickel-hydrogen batteries, which is an essential task, but for Li-ion Pavilion DV2000 battery, the cycle is too frequent, and lithium batteries does not completely eliminate the memory effect, but has greatly reduced the memory effect, if you use the battery is frequent, then you should discharge the battery to the relatively low (about 10 ~ 15%) re-charging, but even if the discharge to the open machines are not (0 ~ 1%), belong to the lithium batteries have greater depth of injury discharge generally every two months to do the operation once it. If you rarely use the battery, then every 3 months as long as the first such operation carried out on it.

Misunderstanding Four: correction to enhance the battery capacity can improve the battery capacity

The so-called correction, when the actual capacity of the Pavilion DV6000 battery and control circuit capacity not the same as the record, the depth of a battery charge and discharge operation, so that a record control circuit to the battery close to the actual situation, this is a true performance of the battery capacity rather than enhance the capacity of the operation, the key factor here is the actual capacity of the battery, if the actual battery capacity than the control circuit in the capacity to record high, correction can increase the battery capacity seems, if the actual capacity than the control circuit the capacity to record low, the correction will reduce the battery capacity seems also that many people debate the reasons for the effect of correction, keep in mind that correction is the true battery capacity is shown by the elimination of the battery and control circuit between the deviation, as demonstrated by the capacity will increase or decrease, this is the status of the battery itself, rather than corrected by your decision. Correction is likely because the battery discharge when the depth of injury, but a substantial reduction in capacity.

Many manufacturers provide a battery calibration procedure carried out, the Windows version and BIOS version, it is best to use these procedures to correct, Windows version can be carried out while working, BIOS version can not be like this.

Tracert and pathping Show route data packets

With the command tracert (Caution : avoid confusion with Linux, where the traceroute command is ) and the appropriate parameters to display the path and all intermediate points (called hops) a packet of data between two hosts. For example, type “tracert www.pcwelt.de ” one . They then learn that the data packet to pcwelt.de goes on – in our specific example see the screenshot – eight hops. Starting with the Fritzbox (which is our default gateway ) of six intermediate stations (for example, your ISP , various routers and gateways) to the destination server pcwelt.de . You also learn how much time the data packet from one station to the next file. For Tracert there under the Free and Shareware Visualization tools that provide a kind of map of the world , with the route of your parcel is located.

Tracert can be used both with an IP address as well as a host name. Tracert is to host the IP address.

The term describes the way TTL Time to Live the life of a data packet in the network. Maximum of one package may go over 255 router, which is Time to Live in each router transition ( Hop ) is reduced by one. TTL reaches 0 and it could not be delivered until then , the packet is discarded.

Pathping : combination of ping and tracert

Pathping is the development of the tracert and ping commands . The upper part of the output is largely the result of tracert . Including a detailed analysis followed by information for transmission of data packets on each hop. All the intermediate routers receive pings , respectively , based on their responses PathPing calculates a statistic. Packet loss and response time are displayed on each router, thus the causes for failure can be a route to quickly identify .

Net: Useful network commands

The net command family to provide a range of functions , not all are necessarily related to the network of your PC and inspiron 9300 battery. The net commands do also have to do with the Microsoft . NET Framework. Some examples of lists : net accounts on the user directives. Net local group shows the existing local user groups. With net local group / add / Tester you will add a new user group called testers. Net local group / add Neuert Tester adds the user Neuert added . With net user neuer_nutzer neues_passwort / add / insert the user with the password to neuer_nutzer neues_passwort .

Net share displays all shares on the local machine. With net share Name_des_freigegebenen_Laufwerks you can view details of the specified share . With ” net session ” to see who the Server is connected – this command is of course only on a server system and not on the client meaning. Net / ? shows all available net commands. net help COMMAND delivers the appropriate help information.

Netsh

Netsh is a shell for network commands dar. An example : You can see little need to uninstall IPV6 and completely reset the IP configuration (install state) with the command ” netsh interface ipv6 uninstall ” and ” netsh interface ip reset c : reset \ . txt. ”

The best protection for your firewall

Myth 3 hardware firewall is better as a software firewall

In fact, the distinction between hardware,Dell inspiron 5000 battery and software firewall is wrong. Even on a hardware firewall software is running . Usually this is a Linux – based operating system with a packet filter. Like any other system can also have this vulnerability and be vulnerable . In fact, already had several suppliers of a hardware firewall to provide updates as their operating systems were dangerous gaps.

The strength of hardware firewalls is elsewhere : they work as opposed to a desktop firewall completely separate from your PC. They come so that the requirement for a firewall to separate two networks , better after (see box).

FIREWALL The FACTS do the programs really,So works a firewall: It separates two networks

A firewall separates two systems from each other. For home users that usually looks like this: On one side is the Internet, on the other one’s PC. The firewall is placed between them : either in the form of a DSL router , such as the widespread Fritzbox , or as a desktop firewall on the PC itself Ideally, both can complement – the protective functions of hardware box and desktop firewall itself .

Why you need a firewall: the only way to stay out worms

A firewall provides protection against malicious code . It blocks all unsolicited requests from the Internet and blocks it from pests , such as worms. This will succeed even in Windows security vulnerabilities , are ready for the no updates. A desktop firewall that runs directly on your PC and Dell latitude d400 battery, works also as an application filter – that is, you will alert you whenever a program wants to go online, where you have previously not expressly authorized . Above all, this function is the last bastion : If a malicious or spying program on anti-virus tool vorbeigeschmuggelt , you are aware , when it wants to establish contact with the Internet.

Weaknesses in a firewall: protection from viruses pry

There appear again and again on pests that bypass the protection and roundabout way to send data to the Internet . For example, take the virus with the rights of Internet Explorer’s connection to the Web. Other viruses can stop the firewall completely and delete , then undisturbed by sending data to the Internet.For example, take the virus with the rights of Internet Explorer’s connection to the Web. Other viruses can stop the firewall completely and delete , then undisturbed by sending data to the Internet.Finally, there is a risk that the firewall is configured incorrectly and thus fulfill their protective function can not.

Consequence: The best protection you get with the combination of hardware firewall (such as via a DSL router) and desktop firewall (such as ZoneAlarm Free , Version 7.0 for Win XP and 7.1 for Vista, Free).

3D Traceroute List: the way of a data packet

The diagnosis Tracert.exe command determines the route of data packets to a destination by ICMP echo packets (Internet Control Message Protocol) broadcasts. Convenient than the command line you use Tracert with 3D Traceroute. The biggest difference from the old-fashioned Windows counterpart: The freeware will show you the way through the Internet as a graphic to illustrate. The graph generated by the tool provides information not only about the number of intermediate stations, but also about their reaction.

Based on the graphic you see at a glance if disturbances occur, and if so, where. Over a number of settings set up the video output according to your pc and its vgp-bps9/s battery.

Visual Route does not, admittedly not quite as complex 3D graphics, this is the readability of the diagrams a trick better than 3D Traceroute. Even with this tool, the user simply URL or IP Adressse a one, and shortly thereafter VisualRoute shows which stations run on the packages. At each station, the tool provides detailed information.

Advanced Remote Info: collect status information on the web

With Advanced Remote Info administrators gather detailed information on Windows workstations. Subsequently, a report on each PC can be displayed. The report contains, among other things, a list of existing hardware and software that is currently logged on user and network configuration on PCs and its Sony vgp-bps8with Windows NT, 2000 or XP.

The scope of the freeware data can be exported for further processing in Excel or HTML format. In addition, other functions are available. For example, can delete file shares on remote computers or create new shares. The system administrator can also uninstall programs on a remote computer, shutdown or reboot can cause the network.

CurrPorts gain: Summary of open ports

No harm, it may be reviewed at regular intervals, which opens ports on the clients and are in use. Well suited for this is the freeware CurrPorts. To start the tool and assign software to the TCP port of the computer to check and let you know what ports programs with which protocols use some. Because the list also displays hidden processes, hidden malware to draw conclusions on possible.

Printer Problems Printers can crash , create a paper jam or a sudden decline in print quality . What you can do about it.

• Paper jam in printerBefore you do anything else, you should try to remove the jammed paper from the printer. Make sure to include the user manual of your device to the pulling out of the paper not to damage the printer. There you will find especially for larger printers may also hints at what points the paper may have jammed and how to get the best there. If you no longer have your manual is the first rule : carefully remove the paper and not a jerk in the direction from which the paper would normally come out too. Generally, a paper jam but easier to avoid than to fix . The first step is the paper evenly and dry place . Creased, torn or dog-eared paper bearing should not be used for printing . You should also keep paper never more than a day in a vertical paper tray. This results in waves and curves, which then may impede the paper feeder. Finally, you should make sure the paper tray always adjust the page size of the leaves. Has the paper too much or too little space , it will probably skew .
• The print quality does not prejudice: First check your printer driver and Compaq presario r3000 battery on certain settings , such as paper type , quality level and the document type. Did you set the wrong type of paper used , for example, high-gloss photo paper instead of normal pages affected by both the pickup settings of your printer, and the amount of ink that is used by default. If all settings to the selected paper and document match , run a cleaning program. Most printers bring this with their driver software. The program cleans the print heads and, if necessary, also be run several times .



• The printer prints very slowly: There are a handful of factors that may affect the printing speed of your printer. First, make sure you do not have the quality in the settings set to high. Depending on where you print , you can also connect to blame for the bottlenecks to be slow . Print , for example, via a Wi – Fi connection , which is often slower than when you are directly connected via USB cable to the printer. Another factor is the configuration of your PC. Most printers rely on memory and processor of the system to which they are connected. Are no longer fresh as a daisy or too small, the machine prints accordingly slower.

Problems with the digicam Although you can not tinker at the inner workings of a camera,acer aspire 1690 battery or a camcorder as on a PC – at least not in any rule. Yet you have a few ways to hold your camera like this to ruin with technical problems, your best shots . More information in:Compaq Presario V4000 battery Dell 1691p Dell gd761

PC Wizard 2010

The tool PC Wizard 2010 comes from the same manufacturer as the popular program CPU -Z for the correct identification of the CPU and ThinkPad x40 battery . In addition to the EXE file for the installation, you can also create a zip file with an Standalone version of PC Wizard 2010 Download . Unzip this file into a separate folder (for example on a USB stick) and run the file “PC Wizard.exe .

When creating a report gives PC Wizard 2010 is also more options than SIW : Click the File menu , click Save as “. Now the tool allows you to either save only the currently displayed selection ( for example, ” System Summary ” ) or the results of a whole category (for example, ” hardware “). This allows you to limit the length of the report useful. Supported file formats are TXT , HTML , RTF , PDF and CSV.

Overall, the surface looks a bit tidier than in SIW , but you have to click several times to see the desired information. Would you like to see , for example, the driver version of the installed video card drivers, you need to left click on “Video “then click the Adapter tab , and finally to ” driver “.

An interesting option is the monitoring on the Windows desktop , as long as the program runs , you will see on the desktop important characteristics such as the CPU clock frequency or temperature . If you do not use this service, you can disable the monitoring in the “Tools” menu under ” Options – Monitoring – Desktop “. This change to take effect, you must start the program , however, new.

Even PC Wizard 2010 shows – as SiSoft Sandra – to network and PDF Printer. In the ” voltage, temperature and fan “you see next to the current temperature data, the rpm of the fan. The unit “rpm “means here the ” Rotary / Revolutions per minute ” , ie the number of revolutions per minute.

In the ” configuration ” is all about the operating system : In addition to the Windows serial number you see here for example the size of the swap file and a list of installed fonts. Also installed Windows updates lists the program. Under ” UpTime Statistics ” will reveal PC Wizard 2010, when the system was installed on this PC, how many restore points have since been set , and even how many blue screens the system has ever produced .

If hardware conflicts occur, you can under “Resources – interrupt request ” to control the assignment of hardware interrupts.

Conclusion:

SIW , SiSoft Sandra Lite and PC Wizard 2010 are a great way to explore the inner workings of the PC and thinkpad t43 battery , without using a screwdriver in his hand. In the meantime, the wealth of information also extends to peripheral devices , operating system and network configuration. Although none of the three featured products perfectly on its own is to leave all three together has it all and reveal nearly every detail about the hardware and the installed drivers. With each of the three programs , you can create a detailed report and thus the hardware characteristics permanently archived , without having to start every time a new diagnostic tool. SIW or PC Wizard 2010 can also start from the USB stick and carry it a diagnosis, without leaving a trace on that PC.

Microsoft products such as Internet Explorer have been distributed too long a favorite target of hackers, malware. Today, however, also offers third-party software such as Adobe Reader hackers a chance to get to your data.

Install all security updates

Attackers have found that some third-party software, like Adobe Reader or Adobe Flash is to be installed virtually on any PC and have exploitable vulnerabilities. To protect themselves and Acer aspire 3000 battery against such threats, you can program how to use Secunia Personal Software Inspector to scan your system for applications that have known security holes and install the necessary updates.

You should update all your programs via currently hold forever. The About.com Antivirus software side is a good starting point to get this information. You can also use McAfee’s Avert Labs Threat Library use the latest threats from the Internet to learn about the.

Although the third-party software is probably the path of least resistance to hackers, the bad boys Microsoft products have not lost sight of. Windows users should then select the option to automatically update the Microsoft products enable and automate the download and installation of critical updates. The automatic update keeps the Windows operating system and Microsoft software, such as Internet Explorer and Office applications, up to date

Security myths

They are doing everything we can to ensure your data security? Or do you feel safe when you surf the net or download data ? Think about it again after we introduce you to five common safety myths about digital security.

I have nothing that would interest an attacker

Average users often think that the data on your computer and Apple PowerBook G4 battery only for themselves have some value , but not for others. Therefore, they worry not so much about the security of their data. However, there are three problems with this way of thinking. First, attackers will often not the data itself, but they want to take control of the computer for sending over this malware and spam to other users. Second, you may indeed be of view that are stored on your PC are not important or sensitive data, but often enough for an attacker ‘s name, address and birth date from stealing your identity and to use such as social networks. And third, the attacks of hackers are mostly automated. Attacks are not usually addressed on a previously selected target , but can strike anyone.
