Laptop power adapter you should know about common sense


Laptop AC Adapter knowledge ( 1 )
Recently, ZOL forum , “Deny Romance ” as we shared a common sense about notebook power adapter , Next we recommend.
First, the power adapter ( hereinafter referred to as the power ) of the nominal voltage and current is what does this mean ?
 First , the nominal voltage general power supply , refers to the open circuit output voltage is not connected to any load outside , when there is no current output voltage, as can be understood , this voltage is the power supply output voltage limit. For the internal power supply voltage of active elements used in the case , even if the mains voltage fluctuations , the output value is constant , as the market is generally small transformers , such as music players and the like with the power , if the mains fluctuations , the output of the power supply will also fluctuate . Generally, ordinary For Apple Laptop AC Adapter no-load voltage is not necessarily real and nominal voltage exactly the same, because the characteristics of electronic components can not be completely the same, so there is a certain degree of error , the error is smaller, conformance requirements for electronic components higher , the production cost is high , so the price also expensive .. In addition , on the nominal current value , regardless of any power supply has a certain degree of resistance, so that when the Replacement Dell Power Supply output current, the voltage drop will be generated internally , cause two things , one is to produce heat, so the power will be hot , the other is causing the output voltage decreases , the equivalent of internal consumption.
Second, are the same nominal voltage supply, the output current is different and can not be used in the same books ?
Supply voltage , the output current is different and can not be used in the same books . The basic principle is that a large nominal current of the power can be used instead of small nominal current of the power . Estimated someone would think so , I feel great nominal current of the power will burn books , because the current big thing. How much current is actually the case in the same voltage depends on the load , Oh, think of junior high school physics will know.

When the books when the high-load operation , the current bigger, books go into standby when the current is smaller, there is a large nominal current of the power supply sufficient current margin. On the contrary , it was replaced with 56w 72w of power have no problem with it , because the power adapter is usually designed to leave a margin , load power must be less than the New HP Laptop Charger , so this place in general use is feasible, but the remaining power headroom rarely , once the books you pick up a lot of peripherals, such as two usb hard drives, then cpu running at full speed , and then there is a base, a CD-ROM drive at full speed to read the disk , plus simultaneously to charge the battery , estimated in danger , we should always to feel your power is not already boiled eggs. So it is best not to use a small current power supply instead of high-current power supply.
Laptop power adapter common sense ( 2 )
Third, the same machine , the power of others gentle , and I always very hot , and why ?
Let us not doubt your power supply have problems, take a look at your books are doing, is not like the above said two USB hard disk, CPU running at full speed , hard disk read and write crazy , drive at full speed to read the disk , while charging the battery , put loud the music , the screen brightness maximum , wireless network card has been detected signal and so on, make good use of power management, according to the task rationally adjust the working status of the books is very important.
Fourth,New Toshiba power Adapter voltage than the nominal voltage of my laptop battery is much higher , it will not be an accident ?
First, we must realize is that power to the laptop power supply and battery for books is different.
Battery -powered , the battery output is pure DC , clean enough, the battery voltage is neither possible nor necessary to design very high , the chemical characteristics of the lithium battery of a power-saving core determines the output voltage of only 3.6V or so, so many batteries are connected in series using three methods , 10.8V also became very popular battery voltage. Some batteries 3.6V nominal value of an integer multiple is slightly larger than some, such as 3.7V or 11.2V , and so , in fact, in order to protect the battery.
Power supply , the situation is more complex , you first need to add the voltage regulator further filtering to ensure that the power supply performance is not a good situation stability, voltage regulator two parts of the city , all the way to the laptop power supply work , another way to charge the battery for Cheap Asus laptop ac adapter that part of the time with the same battery and charging the battery through the battery requires that part of the charge control circuit can only be applied to the batteries , the control circuit can be very complex, so the power voltage must be greater than the batteries have sufficient capacity to supply voltage to the charging control circuit of each unit . Finally a real added voltage on batteries you will never supply nominal voltage. Rest assured.
Another search, we look at the battery charge control circuit includes what things should include primary regulator , precision tunable regulator , SCR adjust pulsation output , voltage output , current feedback , the charging process of recording and computing chips , since the feedback regulation of the charging process parameters, etc. , Oh , is not feeling still very necessary part of the electrical energy consumed ah.
Laptop power adapter common sense ( 3 )
Five , why theoretically wife ‘s power supply is usually better than the non-original ?
Oh, I think this issue should be of concern is that many of the Friends . Theoretically . Original power certainly better, but the actual use may not feel the difference . Normally our device has a voltage input range of security , such as a 2.5 mobile hard disk , which is plus or minus 5% requirement 5V , too high or too low, the protection circuit will stop devices work . If the protection circuit is activated , it means that before this, your machine has been close to or exceeded its design can withstand the upper or lower limits , which are affecting the life of the machine . ( Of course, here referred to non- original MSI Laptop AC Adapter , or good workmanship , poor quality products, they do not mention it. )
The problem may be even more important books of data security, automatic protection sudden stop working for a computer is a terrible thing , especially a lot of friends without the battery . Sometimes the computer restarts and also somehow related to this . For the original power supply , the manufacturers are aware of their power needs to have much of the load capacity of the calculated nominal voltage and current security certainly more accurate . However, if you use a non- wife adapters , such as general-purpose transformers and the like, these problems can not be seriously considered , this is the user from the electrical parameters can only try to find ways to get compatible , but each adapter’s internal resistance is different, nominal voltage tolerance may be different under the nominal current output voltage variation range may be different if you’re not careful measurement of the relevant values ??, certainly , there is a risk . This is the difference between original and non-original here can not say to the poor power supply , ah, this stuff is certainly much less insurance .

Toshiba Laptop Battery Problems

Toshiba has come a long way when it comes to the battery life in their laptops, but that does not make them immune to the occasional hiccup. Poor charging practices can cause issues with battery life, and power-sucking settings can deplete a charged battery, especially an older one, at a surprising rate. For many Toshiba laptops, even temperature can affect whether and how your battery charges and discharges.
Charging New Batteries
If your laptop is brand new, you have an opportunity to maximize your battery’s health from the get-go. CNET authors Asher Moses and Brian Nadel state that long-term battery vitality can be ensured if “when first using your notebook on battery power, [you] let the battery completely drain before you recharge it. Don’t recharge when the battery is only half drained. Do that for at least the first two sessions.” If you continue to do this every time you use your Toshiba laptop battery, you will extend the length of time your laptop can run on battery power.

Power Settings
One of the main reasons battery life is so short on many laptops is because of the power settings. You can access the power settings on a Toshiba either by right-clicking the battery tray icon in the lower-right corner of your screen and click “Power Options”, or by going to Control Panel > Power Options. Here, you can select the settings your computer will use when it is running on battery power, adjust when the display turns off, choose when the computer will go to sleep, and decide how bright your display is. The default “Power Saver” settings adjust the display brightness to about 40%, turn off the display after 3 minutes of inactivity and put the computer to sleep after 15 minutes. Think about which settings make the most sense for you,Toshiba PA3921U-1BRS and adjust your computer accordingly to save power.

Temperature
Extreme temperatures can negatively affect your laptop’s battery. According to Moses and Nadel, you should not expose your battery to extreme heat or cold. Heat causes batteries to lose their charge very quickly and cold batteries don’t perform as well. In addition, some Toshiba laptop batteries can detect when they have heated up too much, and will not charge even when the AC power is plugged in. The computer will display “AC power plugged in; battery not charging,” in this case. If this happens, you can charge the battery by shutting down your computer and letting the battery charge while the computer is off.

Age
Laptop batteries generally last for 2 to 3 years. If your battery is not holding a charge and it is older than 3 years, consider purchasing a new battery. Remember to fully deplete and fully charge the new battery the first few times you use it.

Still Not Charging
If you have considered all of these possible battery problems and find that they are not the reason for the problem,Toshiba PA3921U-1BRS Laptop Battery try taking the battery out and gently cleaning the contacts on the battery and in the laptop’s battery compartment with a dry, lint-free cloth. If there is no improvement, you may need to look into updating the computer’s BIOS or using the recovery CD that came with the laptop to clear any internal problems that may be affecting your battery.

Laptop shutting down Without Warnning

Question:”I have an Dell vostro v131 laptop which is 2 years and 3 months old. I have never changed the battery since I got the laptop. For the past few weeks, my laptop has been shutting down without warning when the battery hits 20%. I want to make sure that it’s a battery change that I should do and not something else. “

Solution:”
the warranty of the dell laptop battery is in most cases only half a year, and most laptop batteries do not run longer than two or three years until the battery life is only one third..

But if the laptop is shutting down without any warning, it is mostly caused by overheating. And if the fan is running most of the time at full speed, it is a sign, that you computer has collected a lot of dust between the cooling fan and the heatsink. The heatsink inside of the laptop have very narrow fins, that will get blocked in approximately half a year. But you can clean it quite easily: Block the fan movement using a stripe of cardboard and use the vacuum cleaner from the air inlet off your computers cooling fan. Some laptop models can be opened easily on the bottom side. If this is with your model, you also can disassemble your laptops cooling fan, and wacuum clean your computer's heat sink. after cleaning your heatsink, your computers cooling fan will run in much lower speed, and your computer will not switch off from overheating. This also will increase your computers life span. “

Solution 2: try freezing the laptop battery for a few days
let it thaw a bit after u pull it out, then put it back and check on the charging in about a half hour if it is charging, you may have a bit more life left….but you need a replacement battery
my battery is to use a small UPS and pull the battery…then 2 or 3 times a year, put in the battery, note the charge level, pull the plug out and use the battery to about 10-20% left, then plug in the power …once it is topped off, remove it and shelve it, til the next time to cycle it , or use the battery if you need it, that’s what it is for, but drain it and top it off at least 3-4 times a year then freeze it overnight once a year and top it off after you freeze it, then remove it again til it is time to cycle it or you need to use the battery
once you replace the battery, go into power options, and change the settings for battery power to shut off when power gets to 20% or 10% at the very least…do not let it go to zero….bad bad bad for the battery.

"Battery Door" - who gave me the battery to check(b)

The time limit for the use of laptop battery

Laptop battery life to a certain degree, in the case of proper use, Asus N55SF Laptop Battery the battery will be a general one and a half years to two years time, Dell Inspiron 510m Battery, with the use of time and increase the frequency of consumption of the battery capacity. In the interview, according to the consumer to reflect the market with some batteries in three months there will be a serious phenomenon of excessive consumption of capacity, which is where the consumers when buying batteries concern. So choose reputable vendors and the quality of a good battery is necessary.
 After-sales service notebook battery protection

In the interview, one of Mr. Hu told reporters in Shanghai last year, he bought a store in a Asus notebookbatteries, business commitments given year warranty. Six months later, the battery can not recharge, can not be used, Mr. Yu Shihu batteries will be given to businesses to enable them to repair, after 2 days, businesses would like to ask Mr. Hu to get the battery, but a few days with Mr. Hu also home the same again to find businesses, they have a variety of reasons to shirk their responsibilities. Mr. Hu later said: should have thought of these small businesses are not formal,Dell Inspiron 500m Battery, Dell Inspiron 510m Battery, Dell Inspiron 600m Battery, it should be a good choice of the credibility of the formal business, so the problem will not be such a trouble, the delay time is not that I feel very bad trouble.

As far as I understand it, there are third-party laptop battery 3 months warranty, or six months, or even one-year warranty, which is to increase for consumers, a quality assurance, but also a number of businessmen, the battery is done sold a , after-sales service to push on the push to block on the block storebattery.co.nz/

For the vast number of notebook battery consumption, at the time of purchase how to choose a business,Dell Inspiron 600m Battery in regard to quality and after-sale can be protected? Not have to worry about at the time of purchase quality issues,Asus N55SF Laptop Battery problems or worry about people themselves can not find that this is a key point.

We hope that more experience have had to buy a friend to participate in the discussion will be experiences to share with you.
