It is important to know how to troubleshoot your LAN adapter.

For many years Samsung has been a popular name in the field of computers and other electronics. The network cards the company makes are widely used in a number of different computer models. While most of the time these LAN adapters will work quite well, it is important for computer users to know how to troubleshoot those adapters when they stop working.

1. Log on to your computer and click on the “Start” button. Choose “Run” from the menu and type “cmd” in the box.

2. Wait for the DOS window to open and type “ipconfig” at the prompt. If you see a “media disconnected” message or fail to get a valid IP address, check the network cable running into your Samsung LAN adapter. Make sure the cable is seated fully in the port.

3. Type “ipconfig /release all” at the prompt. Samsung ATIV Smart PC 500T This will force the network adapter to disconnect. Wait for a few minutes and then type “ipconfig /renew all.” This will force the network to attempt to reconnect.

4. Right-click on the “My Computer” icon and click the “Hardware” tab. Click on the “Device Manager” button and click the plus sign next to the network adapter section.

5. Look for a yellow question mark or a red exclamation point. These are indicators that the network adapter is not working properly. Right-click on the network adapter and choose “Update driver” from the menu to force the operating system to download an updated driver.

6. Log on to the Samsung website and download the latest driver for your Samsung adapter if the operating system fails to install it. Then go back to the Device Manager window and make sure there is no question mark or exclamation point next to the network adapter.

A power cord, or AC adapter, charges a Toshiba laptop battery and powers the laptop. If the battery is not charging while the laptop is plugged into the AC adapter, it is likely that you need to replace either the AC adapter or the battery. You can easily test both to determine which is the cause of the problems. Once you have identified the cause, you need to replace the faulty part. Following the instructions will solve your trouble.

1. Power down the Toshiba laptop. Remove the AC adapter and any other power sources.

2. Slide the battery release mechanism, located on the bottom of a Toshiba laptop, to the right. Continue holding the release mechanism in place while sliding the battery out of the battery bay.

3. Install the AC adapter into the outlet on the right side of the Toshiba laptop. Plug the AC adapter into an electrical outlet that is working. Power on the laptop. This process troubleshoots the AC adapter. If the laptop turns on, the AC adapter is properly functioning. If it does not, replace the AC adapter. Once replaced, the new AC adapter should charge the battery. If it does not, continue troubleshooting the battery.

4. Turn the Toshiba laptop off. Remove the Toshiba PA3822E-1AC3 Laptop AC adapter.

5. Clean the Toshiba battery contacts by dipping a cotton swab in isopropyl alcohol. Rub the cotton swab on the battery and battery bay contacts to remove dust and buildup. While cleaning the contacts, inspect them. If you note corrosion, dings or dents on the battery, replace the battery. Do not use a damaged battery in a laptop as it can cause damage or start a fire.

6. Line up the Toshiba battery contacts with the battery bay contacts. Push the battery downward until it snaps and locks into place.

7. Insert the AC adapter. Charge the battery for eight hours. During this time, do not turn on the laptop or remove the AC adapter.

8. Remove the Toshiba AC adapter. Turn the Toshiba laptop on. Replace the battery with a Toshiba battery if the laptop does not turn on. If it does power on, the battery is charged.

A number of issues can come up with any technology, including with the Samsung ATIV Smart PC 500T1C notebook. Power, display and audio issues are just a few of the problems you might encounter with your laptop. You can troubleshoot most of these problems at home before contacting Samsung for service.

1. Power Issues

1. Remove the battery from your notebook and disconnect the AC adapter if your laptop doesn’t turn on when you hit the power button. Wait 10 seconds and reconnect the AC adapter. Shut the computer down, reconnect the battery and charge it for an hour if the laptop powers on, then disconnect the AC adapter again. If it doesn’t power on, you have a battery charging problem. If the computer does not turn on after you wait 10 seconds and reconnect the AC adapter, call Samsung support.

2. Remove the battery pack from your computer and connect the AC adapter to your computer and a wall outlet if your battery is not charging. If the notebook turns on, you may have a battery issue.

3. Remove the battery pack and examine it to make sure no parts are bent if you are having battery issues. Put the battery pack back in the laptop, connect the AC adapter to your notebook and plug it in to a wall outlet to charge the battery. A red LED light should light up on your laptop to indicate the battery is charging. If it isn’t lit, call Samsung support.

2. Display Issues

4. Check the LED lights on the computer if the screen is blank when you turn it on. You have a power issues if the power light — the last one — is not on. If the first light, the HDD LED, is not on, you have a hardware issue and need to contact Samsung. If the HDD LED is on or flashing, hold the “Fn” key and the up arrow simultaneously to turn the brightness up in case it is turned down.

5. Force the laptop to shut down if it turns on but doesn’t move past the Samsung screen. Press and hold the power button until it turns off. Turn the notebook back on and hit “F2.” Once the setup utility has opened, press “F9” and then hit “Enter” to select “Yes.” Press “F10” then “Enter” to save any changes, let the laptop restart and then restart it again.

6. Hit “Fn” and “F5” at the same time to turn on the backlight in case it was turned off if your screen is dim.

Laptop Adapter/Charger Inside Part & Exegesis By Laptopacadapter.com.au:

Power adapter (Power adapter),in laptop adapter shop also known as an external power supply (switching power supply adapter), it is a small, portable electronic devices and electrical and electronic power supply voltage conversion device, it was the result of in real life, electronic devices are often not directly use household power, because the home, using a 220 volt power supply voltage, while the the universal electronic products generally required supply voltage is about 5 volts to 20 volts. Therefore, the role of the power adapter is crucial (module power). With it, we can facilitate the safe use of these electronic products. Power adapter, what is it? For this problem, Xiaobian collected data be simply summarized.

Composition and application of the power adapter (power adapter works)
The power adapter is common in mobile phones, LCD monitors and notebook computers and other small electronic products. Usually casing, power transformer and rectifier circuit, their output type can be divided into the type of AC output and DC output type; connection can be divided into the wall plug and the desktop. Widely used in the phone Cordless phone, game consoles, language repeater, walkman, notebook computers, cell phones and other devices.

Computer power adapter
The power adapter is widely used in industrial automation and control, military equipment, scientific equipment, LED lighting, industrial equipment, communications equipment, electrical equipment, instrumentation, medical equipment, semiconductor cooling and heating, air purifiers, electronic refrigerator, LCD monitors, LED lighting, communication equipment, audio-visual products, security, computer chassis, digital products and instruments such as the field, and have a negligible role in these areas. Power adapter What?

The role of the power adapter
In general, the power adapter to the role of transformer and rectifier.For example Acer TravelMate 5720 Adapter ，Household AC 220v, and our computer land is DC 12v (as if), and so can be sure that the power adapter is a transformer Chief rectifier. The adapter is a transformer, then we should know, through the transformer transformer AC 220v DC rectifier, here are consumed, which consumed is converted into heat, power adapter fever normal. The transformer is a silicon steel sheet made of, the transformer is energized, magnetic flux is generated, the magnetic flux will incur generated between the force acts in the silicon steel, thereby generating a buzzing sound, which is normal. Burned earth, the sound is not normal, why are many: 1, AC voltage instability. 2, chips breakage. 3, inter-turn short circuit. 4 component damage. By the way, the role of the adapter is to convert alternating current into direct current electronic products.

Power adapter space are generally built-in, general adapter volume is not small, the small volume of the macsshine are external, in order to save space, and to replace is also convenient, mains adapter with high voltage,like Dell GA240PE1-00 Laptop AC Adapter put the inside of the machine is more dangerous.

The power adapter should pay attention to several issues

The label above the power adapter (below adapter) will generally have several needs attention.
First, is the model of the adapter, such as the the Fengyun adapter model is XVE-120100, it tells us several manufacturers, wattage the XVE beginning, generally is XX code, 120100 is to explain this The adapter is 12W 050200 is 10W.

Second, is the adapter INPUT (input), in general, China is generally 100-240V 50-60Hz,like the Fengyun adapter can work in 100V-240V voltage below normal.

Third, the adapter OUTPUT (Output), two figures can be calculated very quickly of this adapter wattage, such as the adapter voltage 12V * current 1A = 12W (power), this power is 12W adapter.

Most laptop power adapter suitable for 100 ~ 240V AC (50/60Hz). Basically most laptop regard the external power supply, a power cord and a host connection, which would reduce the size and weight of the host, and only a handful of models to power the built-in host.

Power adapter has a nameplate above marked power, input and output voltage and current indicators, with particular attention to the range of the input voltage, which is the so-called “travel power adapter”, if the mains voltage only a 110V country, Dell laptop adapter this feature is useful when some parallel laptops are only sold at the origin, this compatible voltage design, or even only a single input voltage of 110V, 220V mains voltage plug will burn.

Summary
The role of the power adapter is the home of the high voltage into low voltage, stable work so that they can work properly. Instead it will bring a lot of inconvenience to our day-to-day use. This paper describes the role, composition and application of the power adapter as well as attention to some problems when using the power adapter.

AC adapters convert electricity in alternating current form from one voltage to another. If you are looking at two AC adapters that both convert, say, 120V AC to 12V AC, it can be confusing to see different wattage ratings (such as 65W vs. 90W) for the two adapters.

What Is a Watt?
A watt is a unit of measurement. This particular unit measures power, or capacity to do work. Watt’s law (named for James Watt, an 18th-century Scottish engineer) states that one watt (1W) is how much power is in an electrical circuit where one ampere (1A), or amp, of current flows across a difference of one volt (1V).

Function
Using the equation P=V x I, where P = power in watts, V = voltage, and I = current, we can determine that an AC adapter rated at 65 watts with an output of 12 volts AC will have a maximum electrical current output of approximately 5.42 amps (12V x 5.42A = about 65W).

An AC adapter with a rating of 90 watts with an output of 12 volts AC will have a maximum electrical current output of 7.5 amps (12V x 7.5A = 90W). Therefore, an AC adapter with a higher power rating (measured in watts) will be able to supply more current to a device it’s connected to.

Practical Application
Since both AC adapters are capable of supplying the same voltage, it may seem like there isn’t much difference between the two. However, the amount of current the adapter can supply should play a major factor in your decision as to which one you will use.

For example, HP Envy X2 Laptop AC Adapter 15V 1.33A 20W device that requires 15V AC and 1.33A will require an AC adapter that is rated for at least that much power (72W). Trying to use a 65W AC adapter will not provide enough power, because the AC adapter will not provide enough electrical current. In this case, the 90W power supply would be the appropriate choice to power the electrical device.

Similarly, since the power rating is considered to be a “maximum allowable power” indication, an AC adapter may be used to power devices that are rated at or below their power rating. If a device requires 12V and 3A (36W), either the 65W or 90W power supply may be used to power it.

Other Considerations
If an electrical device contains a rechargeable battery, an AC adapter that has a higher power rating will allow for faster battery charging: An AC adapter with a higher power rating will allow more electrical current to flow, allowing more of the spare electrical current to flow into the battery.

Cost may also be a factor. Usually, since AC adapters with a higher power rating must be capable of delivering more electrical current for the same amount of voltage, the components required to assemble an AC adapter must be more robust than that of a lower-power-rated AC adapter.

AC adapters with higher power ratings also give off more heat than adapters with lower power ratings. If excess heat is a consideration, an adapter with a higher power rating may not be suitable for the application.

Which AC Adapter Is Right for Me?
While an Hp AC adapter with a higher power rating will allow for faster battery charging times and increased electrical loads, an AC adapter with a lower power rating may suffice, especially where there is a concern about excess heat or higher cost.

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.
