Power adapter failure analysis

Posted by admin on January 7th, 2015

Whether the voltage output of the power adapter failure, incorrect output, poor contact, shell cracking, leading to laptop adapter shop power adapter failure the following categories: power environment does not meet the requirements, physical damage, incorrect use, and other environmental adverse

Reasons:
The power environment does not meet the requirements: unstable power supply guide inside the Asus ADP-180EB D AC power adapter switching transformer components often subjected to the impact of failure, resulting in no output power or output incorrect power adapter can be adapted to a certain voltage range, but often fluctuate power environment, the voltage adapter can also cause varying degrees of damage; does not meet the requirements of the power supply will not only damage the power adapter itself, but also cause damage to other parts of the laptop.

Physical damage: many power adapter failure is the power adapter is often dropped or bumped due for notebook power adapter, are most vulnerable parts of neglect, this collision will not only cause the shell to crack, and sometimes there is no obvious damage in appearance the case, the internal components have been hurt; components due to collision-induced displacement or pin loose, resulting in functional failure of the AC Adapter For Asus power adapter, power adapter soon after powering on or in use burned.

Use is not correct: notebook cable smaller, often stuck or caught in the cracks in the tables and chairs, if the gap is too small, with the passage of time will lead to the cable damaged or in the case of the appearance of non-destructive internal short circuit, open circuit ; when not in use or move the computer, often the power adapter body and cable entwined incorrect winding way, will lead to the Asus ADP-180EB D AC laptop adapter cable with the adapter body occupies a position this paragraph damaged, cause visible damage, short circuit, there is no significant change in appearance, and internal short circuit, open circuit; these reasons lead to power adapter failure, the severe burning power adapter; Some use a fixed environment or have more than one power adapter users, power adapter plugged in, disconnecting the power for a long time, it is neither conducive to environmental protection, will also affect the life of the power adapter.

Other adverse environment: high temperatures or humidity (especially some of the ground of the room more humid) environment using the power adapter, the internal device will overheat and malfunction or moisture short-circuit, resulting in power adapter disabled, burned.

Check Laptop Battery Life In Four Step

Posted by admin on November 28th, 2013

One of the worst things that can happen while working on a laptop is to have your battery die while you are in the middle of an important project. To avoid this, it’s good to know how much life your battery has left in it.

Most laptop computers offer a couple of ways to do this, and there are several free downloads that will put a large battery-life monitor on your screen, meaning you’ll never be caught with a dead battery unexpectedly again.Toshiba NB550D battery for example.

1.Look in your computer’s system tray, which is at the right side of your taskbar near the clock. You should see a battery icon. If it doesn’t show up automatically, click the arrow on the left side of the system tray, which will expand the tray and show all icons.

2.Place your mouse over the battery icon, but don’t click on it. The icon will show roughly how much life is in the Toshiba battery.

3.Hovering your mouse over it will pop up a label showing exactly how much time remains before you run out of power and what percentage of the battery remains charged.

4.Plug in your AC adapter if the battery needs to be charged. The status in the system tray will show that the computer is now running on AC power, and the battery is charging.

How to Rebuild a Dell Laptop Adapter

Posted by admin on October 18th, 2013

If you own a laptop, you may at some point notice that its laptop adapter has failed or is deteriorating, with wires suddenly exposed. Over the last few years, Dell laptops have been known as being faulty, and the adapter is no exception. However, with the right tools, skill and caution, you can repair your adapter by yourself.

Instructions
Examine the LED light that is on when your Dell laptop’s adapter is plugged in and is in working condition. If the light blinks when you wiggle the power adapter while it’s plugged in, it means there is a problem, possibly a short in a wire inside it.

Turn off your Dell laptop and unplug the adapter as well. Then, open the Dell adapter’s clamshell case by using a 7mm flat-headed screwdriver, inserting it between the clamshell and the AC power socket (two- or three-pronged). Keep the blade close to the outer edge of the socket and twist clockwise and counter-clockwise alternately in an attempt to get the clamshell to pop open on either or both sides.

Use either the screwdriver or a 7-mm thin Swiss army knife to cut a crack along the edge of the clamshell, then utilize the blade to expand the crack by about an inch and a half. Separate the outer layer from the interior and tightly twist it.

Cut off the large choke, also known as a ferrite, on your Dell adapter if it is too close to the barrel connector. Use a wire stripper to do this so that you can strip the coax rather than having to sheath away with a cheap tool. Strip away about one inch of the outer sheath, then twist the braid shield together.

Use the knife to remove about 1/4 inch of the insulation from the center electrode and tightly twist it, using a soldering iron to seal the connector. Use electrical tape on it if your soldering is not perfect.

With some skill and much caution, you can repair your Dell laptop’s adapter.

Laptop battery how to maintain?

Posted by admin on September 18th, 2013

Buy a notebook, is not on the notebook, such as their other half to take care of it? I believe that just bought. Many people only relationship like the computer system. Laptop battery you care about it?

Notebook battery maintenance began:
Step / methods
1.When power is connected, the Dell Inspiron 14Z battery can pull or not to pull, pull, pull depends on actual usage: do not disconnect the battery while connecting the DC power battery and does no harm, because the battery is not fully charged will no longer accept any power injection, power will all turn directly to the power supply system of the notebook. But when the high-speed operation of the notebook, internal overheating is best to remove the battery, otherwise it is harmful.

2.long-term use of the Lenovo B450 laptop battery how to save, pay attention to clean the dust inside the computer.
Laptop battery is put photoelectric save or fully charged, should save? Put photoelectric long-term preservation will make the batteries will lose their activity, and even lead to the control circuit protection self-locking and can no longer use the full power will bring long-term preservation security risks, the best method of preservation is to use electricity to about 40% and then stored in cool, dry place, about 20 degrees Celsius is the ideal storage temperature. Of course, the best month to take the battery out with time, both to ensure battery good state of preservation, but not so the battery is completely lost and damage the battery. When the computer for a long time in a dusty environment, it is best to regularly clean up the dust inside the notebook,Dell Inspiron 1545 excessive dust caused by poor heat.

3.How to properly charge laptop battery
Should try to avoid battery power light depleted rechargeable battery as this will give a lot of pressure resulting in damage. More feasible approach is to be charged in about 20-30% of the remaining power. In fact the notebook lithium battery in the number of “light / charge” there is a limit, all used up to recharge would greatly shorten the battery life. The same time, the battery should be charged the Dell PA-20 adapter in a dry place, Also note that the heat problem, which is the enemy of batteries.

4. Measures to extend notebook battery operating time
1 to reduce the brightness of the screen: You can use the fn + down / up key combination to quickly adjust brightness (specific FN + which keys need to see their own laptop).
2 make good use of standby, sleep and other functions: When long time without a computer,Dell XPS 15 ,allowing notebook standby or hibernation, both to save power and prolong the life of the computer.
3 to open cpu SpeedStep function, can significantly extend the battery operation time: cpu speedstep in the bios default boot When using the battery, the CPU automatically reduced frequency use, in order to save energy. Not open the boot by F2 into BIOS Performance, set Speedstep Enable as to “Enabled”.
4 when using theToshiba PA3715E-1AC3 battery, try to turn off the wireless, Bluetooth and infrared port. Removed without the use of peripherals to avoid to enable large 3D program, games, etc., to reduce unnecessary battery consumption.

Dell laptop doesn’t recognize the ac adaptor

Posted by admin on August 28th, 2013

“Basically when I plug it in I get a nice popup telling me that it couldn’t detect that its a Dell power supply so it won’t charge the battery and underclocks the system. It still works for other purposes (that is, giving power)

I thought it was the actual power supply cable so I bought a new one, that worked for a while, provided I inserted it at JUST THE RIGHT angle. But now that’s not working anymore, so I assume its the part which connects to the computer.

The battery charging I can live without, the underclocking I can’t. I’d like a way around this issue. Things I’ve tried:

Updating the BIOS
Replacing the power supply cable
Inserting it at different angles
Turning it off and on again
Swearing at it
Twisting it while inserting it
So, is there a workaround somehow? I’d like to avoid taking out my soldering kit and risking permanently damaging expensive equipment if that’s allright. I’m hoping for a software solution.

Added: The exact model is a Del Inspirion N5010″

Answer:” I suppose that there would be a few models that DO have more than two wires going down the ac cable; however if you follow my trouble shooting guide your problem will be solved.
1: Check battery
2: Check AD adapter
3: Check DC power jack to motherboard connector/wire/ whatever it is

if it is not one of those three things then you have faulty circuitry on the motherboard that can be repaired by someone with experience – not by the folks at Best Buy – not likely at any local computer repair shop either… you need a tech that has advanced skills (and tools) <br />
if your problem is the Dell DA130PE1-00 ac adapter because Dell has a build in mechanism to make sure the adapter is Dell before allowing it to charge the battery. However, even if the adapter is Dell, if the identifier chip inside the adapter is broken, the laptop would refuse to recognize the Dell XPS 15 L502x adapter and stop charging. It seems that your laptop was starting to have the problem when it shows you the message that ac adapter cannot be recognized.

You can follow this Dell’s troubleshooting guide to try to get the laptop to recognize the charger. It might not work for your laptop because it is a bit outdated.
http://ftp1.us.dell.com/diags/R66243.htm

If the troubleshooting does not work, most likely, you will have to buy a new adapter for Dell XPS 15 L502x since the laptop cannot identify the charger as Dell anymore. However, before you buy a new charger, borrow someone else’s charger to make sure it will charge the laptop and that is the problem for sure. I wouldn’t want you to waste money on a part that is not necessary.”

laptop AC adapter not recognized

Posted by admin on July 21st, 2013

Every time I turn on my Dell Inspiron 15R laptop, I get the following message:

“The AC adapter wattage and type cannot be determined. The battery may not charge. The system will adjust the performance to match the power available. Please connect a Dell 130W AC adapter or greater for the best system performance.”

I don’t know why I am getting this message since:

– I am using the 130W Dell AC adapter that came with the laptop

– The adapter is charging the battery properly

– The green light on the Dell DA130PE1-00 adapter stays on all the time when in use

– The port connection is fine

So, other than this annoying error message, everything seems to be working fine.

Solution:

Please share the exact error message that you are getting from the system. Please check if the charging port on the laptop is loose. Connect an alternate laptop power ac adapter to see if that works fine with the system.

Do you see light on Dell AC Adapter? If yes, please follow the below steps:

Please check the status of the AC Adapter in BIOS:

Restart the system and keep tapping ‘F2’ as soon as the Dell logo appears.

Under ‘System’, go to ‘Device Info’.

Check the status of Dell Xps L702X Adapter.

Note: Use arrow keys to navigate in BIOS.

Also, check the battery health in BIOS:

Go to ‘System’ and go to ‘Battery Info’ and also check ‘Battery Health’.

Also, boot the system in Windows and place the cursor on the battery icon on the right bottom corner of the system and it will show either of the messages:

Plugged in, charging.

Plugged in, not charging.

If you are getting ‘Plugged in, not charging’ message, I will recommend you to update the BIOS:

Please find the link for BIOS update: http://dell.to/SEKdFG

Note: The Dell XPS 15 L502x ac adapter should be connected and the battery should be at least 10% charged. Please disconnect all the external devices connected to the system before updating the BIOS. Please save all the unsaved data as your system will restart automatically while updating the BIOS.
