I plugged in a laptop using a universal laptop and it fried it

I plugged in a laptop using a universal laptop power adapter, and now it stinks.

I plugged in a laptop using a universal laptop power adapter, and now it stinks as if it burned out or shorted before. The adapter probably used the wrong voltage. Should I only replace the power connector board? Or the whole system board?

Connecting a power adapter with the wrong voltage or current can be deadly for most electronics, and especially "sensitive" ones, such as laptops... If I were you, I wouldn't take the risk - and change the whole system board!

Good luck,
Pelu.

Laptop is turning on and off


Remove the AC adapter (Charger)

PROPER method is to disconnect the power cord of the AC adapter, from power; THEN unplug the AC adapter from the laptop.

Same thing in reverse to plug the AC adapter back in.
AC adapter is plugged into laptop, THEN AC adapter is plugged into power.

Unplugging the AC adapter from the laptop, while being plugged into power; can cause a Voltage Spike.

You may get away with it for years, and several laptops; and have no problems.

However it only takes ONCE, to fry out the SMD fuses, Multi-Layer Ceramic Capacitors, and Power MOSFET's, on the laptop motherboard's DC to DC circuit.

Jus sayin'.

Moving on........

AC adapter removed, remove the Battery.
Press the Power On button in, and hold in for a count of 10 seconds.
Let go.
Do this procedure 2 more times.

(Draining residual power)

Reinstall the Battery. Attach the AC adapter, plug AC adapter into power. Let the Battery charge 24 hours.
Then turn the laptop on, and tell me what happened.

Usb powered adapters for laptops


Use a universal power adapter. This is perhaps the most obvious solution to your battery woes. Readily found at most retail outlets that carry electronics, a universal power adapter can range anywhere in price from $30 to $100 or more. The adapter comes with multiple tips, one of which will likely fit your laptop's charging port. When plugged in, the adapter will not only power your laptop, but will charge its battery as well.

I was given a easy pc E700 netbbok without any adapters. The battery was low, so I used a sord I had at home to work on for an hour trying to set it up for my wireless internet...anyway I havent figured...


TRY THIS...TAKE YOUR BATTERY OUT...AND USE THE POWER CORD YOU STARTED OUT WITH...SINCE YOU WHERE ABLE TO POWER YOUR COMPUTER ON... SEE IF THIS WILL START YOUR COMPUTER...YOUR BATTERY MAY HAVE BEEN THE PROBLEM IN THE FIRST PLACE.

IF THE ADAPTER YOU PURCHASED HAD A BOX(TRANSFORMER) TO PLUG IN...THEN THE BURNT SMELL WILL BE...THE ADAPTER TRANSFORMER BLEW.

MOST UNIVERSAL POWER ADAPTERS COME WITH ASSORTED SIZES FOR USB PORTS...SOUNDS LIKE THE SALEMAN/WOMAN GAVE YOU THE WRONG POWER SOURCE FOR YOUR NOTEBOOK. TAKE IT BACK...AND GET YOUR MONEY BACK!

BATTERIES ARE VERY EXPENSIVE, SO IF YOU ARE ABLE TO GET YOUR COMPUTER TO COME ON, THEN JUST LEAVE THE BATTERY OUT!

HAVE YOU EVER NOTICED...WHEN YOU GO INTO THE STORES...AND ALL THE COMPUTERS ARE TURNED ON...THIS IS BECAUSE THEY TAKE THE BATTERIES OUT, SO NOT TO RUN THE LIFE OF THE BATTERY DOWN OR OUT!

IF YOU NEED FURTHER ASSISTANCE, PLEASE DON'T HESITATE TO CONTACT ME!

KIND REGARDS!

HI there! I am using a targus universal wall power adaptor for laptops, it has an output of 19.5 V and 90 W. I was wondering if I could use this to charge my UK laptop from ADVENT. The charger for this has...


The wattage is to different, the wattage for the adapter is 90watts, and the charge for the advent is only 65w.

You can always try it, but you risk damaging your battery, or motherboard.

hello,

you are right, the adapter used a wrong voltageand is burnt.

i strongly advice you replace the whole system board.

simply because you might not be able to detect if there is a component on the system board that is affected.

take care

Power adapter port on motherboard fried, cannot power on laptop. The original HP adapter burned up, purchased a universal and it also stopped working. I could only power on laptop with my charged battery...


Get you an external battery laptop charger and charge the battery that way.  Your gonna have to open this puppy up and replace the power port IC board if you want to charge by AC cord. Your non factory charger could have fried the board.  The board isn't too spendy, but you gotta know what your doing or you will crack the case or damage other parts when opening this thing up.

Charging the mp3mp4 player


  1. Get a USB wall charger. These are AC adapters that plug directly into the outlet. You then plug the USB from your MP3 into the port on the adapter.
  2. Charge your MP3 player on the go. There are also charging kits that plug into the cigarette lighter or power plug in your car. These kits come with a DC power adapter that has a port on the end for you to plug in your MP3.
  3. Acquire Apple iPod specific chargers. When you need to charge your iPod music player through an outlet, look for the Universal USB car charger or the Universal USB travel charger made specifically for Apple products.
Make sure that you have your player on a power strip or surge protector so that if you get a surge you wont fry your player.

Power supply doesn't seem to supply power to Gateway labtop


Well its likely that you could have damaged the power cord. If one of the internal wires got yanked when your foot caught the cord it could have lost it's connection. Try going to an electronics store and asking if they have any universal adapters, look on the back and see if your laptop model is supported. Try it and see if it works, if not return the cord and the problem will be with the female plug in the back of the laptop. Like you said its probably not the laptop

Hope this helps, please comment back if you have any further questions or information about the problem. Feel free to leave positive feedback if this helps, thanks for stopping by at Fixya!

Sony Vaio ac adapter submerged


If the ac adapter was plugged into the laptop at the time may be bad news. Unplug AC adapter, take out the battery and hold power button for 10 seconds. Then connect AC adapter and hit power. If that doesn't work put battery back in without ac adapter and hit power button.

If neither test works bring to repair center for diagnosis. Best case AC adapter would need replacing. Worst case Motherboard fried.

Thanks
